8:45. Energy consumption = 2L gasoline + 7.3kWh / 100km. With battery capacity 17.3kWh, it will be depleted in 237km. So, in order to get 1500km range, you wil need 30l gasoline + charging the battery from outside source every 237km. My point is that the title is misleading.
This is brilliant!! You have the efficient power and torque delivery of an electric motor, without range anxiety!! 2 liters / 100km is over 100 mpg. I want one!!!!
I don't get the hate. It's related to how a diesel electric freight train works. Engine is only running to recharge the batteries that run the car. No car has this technology, and to scale the technology down to the size of a car is impressive. Is it as efficient as a BEV? No. However, it gets around a major problem that BEV's have. You need to have a house, or someplace to charge a BEV, which is not always available outside of the major cities and first world countries. Not everyone is well off to own a house with solar panels, so this tech could help.
I understand the hate but I don't think it's warranted. Right now the cost per mile to drive this car is roughly the same as electric, except electric is getting cheaper and oil is getting more expensive. Battery technology is going to keep improving to the point where they have the same range anyway, and infrastructure is only getting better. Right now this mostly solves the energy density problem, which means the concept is not really that useful for small passenger vehicles, but more for buses, trains, maybe airplanes and for transport semi trucks.
A great idea! I think this makes more sense than carrying a gigantic and heavy battery all the time. Also the excess heat from the generator will be used to heat the cabin which further increases total efficiency. Heating a pure EV from cold used a big portion of the battery. But perhaps they should use a microturbine as a generator. It has similar efficiency, but burns much cleaner (more complete combustion).
although I'd love to see a micro-turbine range extended EV for the novelty (see ERDEngineering's RX7 😆) ... even the smallest turbines produce incredible noise. It seems they might be better at maintaining battery charge in some continuous high-speed application, but not so good while starting and stopping in most driving situations. If accurate, 2L/100km is in the neighborhood of a Yamaha Zuma 50cc scooter - that would make biofuels or green gasoline actually sustainable (more efficient than sourcing electricity from the grid unless its coming from >50% renewable or nuclear sources).
Turbines are crazy compact yes, but they're not that efficient and they're only cleaner if you don't have an exhaust system which can't really be done on a turbine. Turbines are great if heat or power per weight is what you want, hence most modern diesels have one to get the actual engine up to temperature fast enough. Linear generators or opposing pistons (2 pistons in the same cylinder) have potential, less moving parts and easier to pack. You can really optimise for efficiency if the engine can just run at its most efficient setting no matter what. Ideally allow it to pre-heat the batteries (less degradation) in the winter and use the gas engine as a heat sink for the battery coolant so it's already warmed up a bit before kicking on when exiting the city.
This is essentially an Eletric drive vehicle. The gas engine can be optimized to produce electricity. Hopefully Elon Musk is watching this video and will offer this as another Model option.
The extra heat from the generator can be used to heat the interior of the vehicle (like traditional ICE cars). That will in practice make it much more than 40% efficient. I really think this is the future. Especially for larger vehicles.
Yep, recycling the waste heat from the inevitable combustion losses is the right way to go, its how cars have been made for decades so its best to use a tried and true system :)
New batteries are on the way, within a few years the range will be over a 1000 km, a much lighter battery pack & recharge almost instant. Combustion is the past, biofuel is an awful idea.
@@nyali2 what materials are used for the batteries? are they recyclable? what is the carbon footprint of their production? how safe are they? do you need to replace a whole pack or only a small unit when it gets damaged? Just bc the car doesn't emit CO2 doesn't mean it's better for the environment overall. A couple years ago a Range Rover with 5.0 V8 doing 17mpg was better for the environment than a Prius bc the Range Rover didn't require the battery pack. A single cargo ship produces more CO2 and other green house gasses as 50 million cars. Seventeen largest ships in the world produce more CO2 than ALL THE CARS IN THE WORLD COMBINED! Having to ship massive quantities of lithium and rare earth metals doesn't seem like such a great idea in the light of this...
Apparently if we keep mining Lithium at the current rate it will take 10,000years to electrify the World's cars, trucks and buses. Of course we can open more mines, but we mine the easy stuff first, it'll get more difficult as we have to progress to lower grade deposits.
Absolutely freakin love this. THIS is the way forward for the developed world for cold regions, vast regions, and urban areas that lack home charging ability. This car will use so little fuel that it will produce negligible pollution, and the fuel can be expensive, synthetic, and renewably sourced. It won't matter. The engine layout is good, but piston side forces could have been eliminated with rhombic drive. Mazda is working on a range extender rotary, which will have 3 moving parts and be the size of a large shoe box. Toyota is working on a free piston linear generator range extender. This is really the holy grail, the best of everything.
Sorry I’m American so I did the conversion, he’s saying he has developed an engine that gets 120 miles per gallon????? but isn’t mass producing it?? why?????? That's incredible!!! and this is a WAY better hybrid system than most car manufactures currently have!!! I love getting the benefits of both electric and gasoline!!!!
This is a range-extended electric, not a hybrid electric. That's not a valid comparison. VW had a 2 cyl diesel range extended concept that got over 200mpg over 10 years ago.
@@someotherdude And the fact that VW never decided to try to make a cheaper consumer version of the XL1 is baffling. There's no point going gas to electric cold turkey all at once, you need to wean society off of gas powered cars if that is even the ideal result, which it isn't, since high enough conversion efficiency from crops to gas to electric in cars is far higher overall efficiency than batteries, of which we're nearing the physical limit of capacity. The theoretical limit of NCA (Tesla) batteries is 274 mAh/g and the limit for Li-S batteries is 1675 mAh/g, and the gravimetric density changes based on discharge voltage, although Li-S has been found to have very low cycle life to not be viable.
This makes perfect sense to me. Now I see a car that will work for me. I spend most of the working week driving about 50 miles a day. But on the weekends I drive about 100-200 miles a day, sometimes even 400.
As a model Y, I would actually love to get this installed! Best of both worlds. Full EV for local driving but when longer trips or even if you can’t charge at home.
Woohoo there are really alot of comments.. now here my opinion based on your input: 1) Its killing the purpose of EVs: No its NOT. You can also drive pure electric and you still drive pure electric. the engine is just recharging the battery. You need to understand that the engine is HIGHLY efficicent. Usually fuel engines have max 35% efficiency and during accelerating they run in load ranges that are not the optimum. This engine always runs in perfect conditions with 40% efficieny. Thus its VERY environmental friendly. 2) Its stupid because you now have more maintenance: Wrong - the engine concept is super basic. No timing belt to change. all maintenance would be somtimes new plugs, an oil change, maybe filters. How long does it take.. maybe 30mins ? costs ? almost nothing.. The benefits having this engine are clearly higher than the downside of maintenance 3) Range Well 1500KM with 30L is correct - watch the interview at 14:30. If you charge the battery every 1-2 days you get 1500km out of 30L. in fact range on a single trip would be 800. This 1,500-km range comes with a fully charged battery pack. It is equivalent to being able to run a little more than 930 miles on a tank. The 700-km (436-mi) range shows up in the worst-case scenario: a depleted battery and running the car solely at high speeds! 4)It does not help the environment In fact in mass it does more than a tesla. Full EV is not possible with the infrastructure today. To get CO2 QUICKLY down we need this concept to roll out EV quickly to the masses. Charging infrastructure is not ready yet and also production of EVs is too expensive right now to make this technology ready for the masses. As said in this video. You could get an electric car with this concept for 20.000 EUR - Look at the prices Tesla is charging - Who is able to afford this ? Def. not the average people out there... It would be a bigger benefit for the environment to get all cars down to 2L / 100km instead of driving a few EVs which are not changing anything in the real world statistics of CO2 emission... And think about Bio fuels... when you just need 2L per 100KM then more expensive biofuels make sense!!
It's a hybrid EV and I think this is a brilliant idea because u can add a really long range and there is another reason that this kind of idea is more suitable for some country's like here in my country we are not allowed to import EV's because there is no infrastructure for it so we need this kind of technology in my opinion Nice video by the way 👍
Nice point.... But I think that they should had use a hydrogen engine (i don't know anything about it but they Are avle to use it in cars) and solar roof just an idea and the time that Eva get to evert country i think that there should be a network in You're country to
Exactly. I might also add that pretty much every country's grid would have difficulty handling an all electric fleet. I take it you live in Africa? An all electric car might actually work better there than here, you could conceivably charge the battery from solar panels on a roof, possibly economic in the tropics where you get really strong sunlight, but certainly not here in Scotland, though that doesn't stop green halfwits promoting it.
I understand that this is a more affordable car right now, but instead of wasting our time on this and work on better battery technology than we can achieve affordable ev cars, the right way.
So you are saying: lets wait another decade? Batteries will be expensive if (and this is a big if) batteries will be good enough to overcome the problems of the batteries we are experiencing today.
@@hermanstokbrood no what we are saying is the concept is stupid. Had this been a hydrogen fuel cell technology I could understand it. But this takes an efficient design gives it the middle finger and slaps you in the face. Oh, lets put a generator in an electric car. Thats not stupid at all. If you want smarter rig a flywheel off each wheel and charge it that way.
@@jamesirwin7677 Waiting for better batteries seems to me a waste of time. So we have to think of something better in the meantime. Hydrogen fuel cell technology isn't efficient at all. It looses to much energy just by making it. You can't fill your tank everywhere either which is even a bigger no-no for most people. Don't get me wrong, I don't think this solution is the best we can come up with but it is a step in the good direction and we can do it now waiting for better batteries to come.
That's assuming that we can significantly improve the battery tech. We probably need to double the power density and halve the price for all electric cars to go mainstream. In any case we would still have a huge cost to upgrade our electricity infrastructure to accommodate these new batteries. Do you think its feasible to charge a 100kwhr battery in the same time it takes to fill your gas tank? 1 MW charger anybody!?
@@colinmacdonald1869 Yeah, better batteries don't grow on trees. Graphene seems to be the solution but this is promised to be the holy grail for a decade by now. Progress is very slow. So, I think this company is walking the right path for now. Don't waste time just waiting for batteries that might never be good enough for the masses. I thank Elon Musk to be bold enough to start Tesla. It isn't the perfect car yet but the Model 3 was the best selling car in my country for 2019. Just because the government knows their priority. We have still a way to go but all new companies coming with any solution is better than none.
What is the power of your engine ? Did you consider using it for a power backup generator ? If it is really so quiet and smooth you will blow the competition in North America out of water if you can sell it for a competitive price.
I love the concept. For America, I would like to see it in a minivan with 75-100 mile battery range. That would cover virtually all urban use as a pure EV, while offering no stress, zero compromise family vacation travel at 50+ mpg. Even light towing! Not mentioned in the video is the fact that this system can eliminate all the cold weather disadvantages of pure BEVs.
I agree, seems like a level up in hybrid technology. I always believe that hybrid cars is the transitional technology period to full electric, with every country moving into sustainability in my opinion is the best way to transition into full electric while weening off Petro, but in the political world seems like they are pushing everyone into electric the wrong ways with little to no transitional period for the technology to catch up.
Did you do it? I’ve a ‘21 M3 on over 100k would do this but would rather convert my other vehicles to range extenders first. It’s great but would surely void most warranties.
Fantastic idea that should have been standard when it was implemented a century ago with the 1916 Owen Magnetic. Definitely the best solution for today eliminating range anxiety, speeding up refueling times and reducing the heavy and expensive battery found in full B.E.V.

Next best " new" thing mini nuklear powerplant range 25 years of running 😁
I can see them making cars that will be fully recyclable and batteries that will last many years without worry of needing a change for the life of the car.
You guys don't get the point... This would allow to make cheaper electric cars! Smaller battery, greater range = less cost of production, less cost of buying All of you complaining about how this is burning folli fuels, while in reality this would just simplify the switch to electric cars.
This is not a Prius, but is exactly like the Chevrolet Volt, which is an electric vehicle with an onboard gas generator range extender. Not a new concept, Chevrolet did it from 2011 to 2019.
This car actually proves how bad current petrol cars currently are. It's appearantly capeble of driving a 1000km with just 30 liters of petrol. Call me any petrol car that can do that and remember, a model 3 is not the smallest car at all.
This will work great if they can make a plug-n-play version of it ….I.e. don’t remove Tesla battery or change any of Tesla electronics - connect up to extender to the existing charging circuit and price it under 5000 Euros + maybe another 1000 Euros for installation. This can just act as a power plant when car is not moving and thus eliminate all range anxiety as we can then charge it anywhere and not worry about availability of ev chargers.
This is the best transition to EV. I really like the concept of a Extended Range EV, especially in North America. If 90% lf the time you drive less tha 100 miles per day, why don't share all the lithium between 2 or 3 cars with an extended range when needed.
I like it. It is a Prius plug-in with 2.5x more efficient ICE and stronger electric motors. 2l per 100km vs 5 l/100km. I just don't like the idea of exhaust ending in front of the cabin. I wouldn't like increased risk of being poisoned by fumes.
Damn, people are haters. How is no one impressed with the range! It'd astounding how far that can go. From a cost standpoint from the customers, it must be cheaper to fill up the tank for the constant recharging than to re charge a Tesla battery 3-4 times thus saving time and money!
Yep that's exactly it. This is a whole nother ball game I wished serious production of this was happening as fast as possible. Like teaming up with a German car company and start production in a year or two seeing as this video is a year old
would be nice if they would make something that weighs about 150lbs and puts out about 10kw that fits on a trailer hitch to give any electric car a bit more range.
Da gibt es als Themen einmal eine Vorstellung des Generators, dessen Laufgeräusch und -ruhe, aber vor allem das Arbeitsprinzip, denn in einer Animation waren 2 gegenläufig rotierende Zylinder mit 2x 20 kW Generatoren zu sehen, die ja reichen würden, den E-Motor direkt anzutreiben Nehmen wir an, die 40 kW liegen im Drehzahloptimum zu 95% vor, dann wären es 38 kW. Wozu braucht der Hybrid dann noch 7 kW aus dem Akku oder läuft der Wagen im Standardbetrieb mit 20 kW und die 7 kW on Top aus der Batterie bringen dann gesamt 27,5 kW für grob 150 km / h im model 3 auf die Straße und mit leerem Akku gäbe es eine weitere Reichweite von bis 800 km, dann aber limitiert auf max 20 kW, was im model 3 wohl 125 km/h entspräche. Die 2 Liter Diesel haben grob als 2 kg Diesel einen Energiegehalt von 22 kWh ... nur wie kann das bei 40% Effizienz oder 8,8 kW für 1h Betrieb reichen, wie es das Generator Video zeigte. Eins bleibt ja dann immerhin kein Thema: Heizen im Winter kosten dann keine Reichweite mehr. Jedenfalls ist der 2 Zylinder Generator mit grob 20cm Tiefe und 70 Breite x 50 cm kompakt und sehr leistungsstark geraten verglichen mit Honda Notstrom Aggregaten. An sich erinnert mich das an den alten U-Boot Konzeptantrieb aus dem 2. WK.
Great idea ... currently we use 2 cars ... a bev for 250 km radius and a blue efficiency diesel. Our first bev sucked from day 1 ... a tesla that had issues from day one. 400 km for each try to fix it cause Tesla service center are too far away. Now we have 4 service stations within 20km but this car does not need a repair... cause it simply runs ... or charges cause range is the missing point of the new, but if range matters our Mercedes blue efficiency Diesel is unbeatable. BMW i3 had a similiar range extender concept ... but did not succeed ...
The thing I love about having a combustion range extender is that you can use the excess heat to heat up the cabin (thus dramatically increasing total efficiency). Also, the lower total weight means the tires wear longer and don't produce so much rubber pollution and airborne dust. Perhaps a microturbine would be even better as a range extender because it burns the fuel more completely and thus emits a much cleaner exhaust gas.
Modern Teslas use a heat pump to cool the battery pack, there is a fair amount of waste heat in a 100KWhr pack. You probably only need 500W to heat a car, that being said if you're talking about heating s car in Iowa, January, there probably isn't any waste heat and the battery has problem lost 50% of it's range coz it's cold.
How disappointed i am when seeing this video today....reason, i had this idea 3 days ago ....calculated how this was way way efficient and cheap to make ...also had this idea if only it would be possible to have an alternator that with 10% input gives out 100% output...this is a game changer...if only it would be possible , which it is but the tech is years to come with major breakthrough.. Got this idea, but its already showed up..Big Thumbs up to this guys..this is great news and happy that someone actually thought of it....This is the next tech that consumers don't even know yet how best it will suit them.✨💯🇰🇪
Ha! I had the same idea years ago, I hate parallel hybrids they're just messy and complicated, I've been wondering why nobody has tried using a teensy weensy engine to charge a battery and then just run an e motor. My reasoning being I only 10% of the power 90% of the time. Only could find one serial hybrid, the now defunct Fisker. Then I stumbled on this completely by accident.
@@electrohawk1 It is lighter, cheaper, has more range, is conveniently to refuel everywhere with existing infrastructure, has lower total CO2 emissions and...?
@@ericwanyonyi2445 put this in an overlander vehicle and power all sorts of accessories via the generator. Doesn't make sense in a sedan where superchargers are plentiful 17kWh battery lol
Discharging and charging a small battery like that will degree the lifespan of the battery. But! Since it’s a small battery, they can be purchased or replace for a small fraction. Not often tho. So yes, 2 liters for 100km is revolutionary. It’s actually cost effective and ensures your trip. Hybrid is the way to go.
This is what the prius should have been, a electric gasoline hybrid. I mean it's a great idea a plug in for short trips with the optimized generator for longer trips . But it feels a bit late to the game and it's not new tech, trains have been doing this for a while now.
I find it funny how we kept throwing train and marine technology at cars and then diesel-electric was kind of forgotten in the automotive industry. We had steam trains and chucked steam at cars only to find out it was either not very good or we couldn't make it good enough, then we took other tech and decided to throw motors from grid-powered machinery at cars and realized batteries were super heavy and sucked, so we went all-gas. Then nearly a century later we decided electric was good enough and we've forgotten about gas at the sacrifice of personal independence and range. For use in a city with short trips you only need maybe 80 miles not 400, so that's 80% less battery weight, and a lightweight gas generator plus fuel is far less than the weight that was saved, so 80 miles battery-only range becomes maybe 85 instead. Once again public opinion, marketing and politics have ruined progress. Edit: The average driving distance in an urban environment is around 36 miles per day. So 80 miles even is overkill :P
Well I thought you rerouted HVAC system to use waste heat of the petrol engine. Reduced battery size also makes the motor less powerful. Basically devalue the vehicle. It's proof of concept alright but it's a really old concept, Prius is demonstrating it everyday on the street.
@@honeybee0414 lol what is the most power they can get out of a 17kWh battery this is similar to the defunct fisker karma... Performance is not scalable ... this is only suitable for an econo car not a platform that can compete with ICE performance vehicles
I'm still waiting patiently for a Obrist package for retrofitting to existing Petrol and Diesel powered vehicles. Imagine if I am able to properly convert a commercial vehicle or even a recreation vehicle for this purpose. Replacing existing internal combustion only powered vehicles with this "Hyper Hybrid" concept is exceptional and will help us meet our carbon goals before 2050.
I love it. I just wish there was a trailor version for my Rav4. It only goes 65 miles till I have to stop and recharge. I wish there was a way to hook up this system in a trailer in back to extend the range. I have seen another car built to do that. Looking for a range extender for my EV.
so basically a step backwards? what a joke. EVs not only help the environment but the whole point is to avoid the gas and maintenance costs that come with gas cars. Honestly, how can you be serious about this? fast charging is the way to address range. not this nonsense with hybrids.
On a longterm yes. But who has EVs right now? People who have to money to afford them. But who emits the most co2 ? Yes the people who can’t afford crazy prices Tesla or others charge. To quickly get co2 down there is no way around super efficient hybrids. Infrastructure can’t be changed that fast.
@@TechMagnetWith the new Zoe and Corsa e/208e there are affordable electric vehicles on the market. I'm living in rural Bavaria and I do not need 800km of Range without stopping. 250km per charge is fine. And I can charge at home.
@@TechMagnet sounds like the oil company has you by your little balls too. I can't wait for this company to fail miserably. This would have been relevant and innovative in 2008, not today. I live here in California, and yes Tesla's are expensive, but I probably see at least 10 every day. And that's not counting electric cars made by different companies. This is such a step backwards, it's hilarious.
Well, they could update the engine with the 55% efficient SkyActivX or perhaps wait for the 65% efficient LiquidPiston engine once it reaches production now that they aren't tied up with what I believe was a military contract. Also replace the battery entirely with supercapacitors or sodium-ion to eliminate the use of lithium-cobalt and therefore greatly reduce the production carbon footprint of the car. It takes a few dozens of thousands of kilometers before any Tesla breaks even with a vehicle like a 3rd or 4th gen Mazda3, and even then the battery has already lost at least a tenth of its original range, perhaps more depending on charging habits and how much "fun-having" you do, aka time at WOT, as well as weather conditions since equatorial or arctic weather (the latter being me up here in the tundra-like-winters of Ontario) damages the battery, the former overheats and overstresses the lithium while the latter reduces range and therefore increases the charge cycles which reduces lifespan. Its all complex, so you might as well cut out the more chemically complex bits and use the simplistic and efficient creations of our forefathers rather than reinventing the wheel.
Congrats! you built a Chevy volt! People are trading in Kias to buy a model 3 so price isnt the biggest issue. At least not in my part of the world where people will pay 80,000 + for a pickup truck. Good concept but 5 to ten years too late. Bevs are the future. To me it just dosnt make sense to haul 2 power trains around to get where you are going. I hope Teslas battery day will put all this hybrid stuff to rest.
Yea and yours or my part of the world are small compared to the India where EVs just exist on the paper. Still we are living on the same planet and getting CO2 down with EVs is something to dream about. Chevy volt is different though. When the engine is running it may be periodically mechanically linked (by a clutch) to a planetary gear set, and hence the output axle. Emitting way more pollutants than this just acting as a generator
Look at how many cars Tesla has sold. U think that makes an impact ? With those huge batteries Tesla is using the carbon fibre footprint doesn’t look good aswell. And if u can bring the majority of cars down to 2L this makes more a difference than all units Tesla sold so far.
@@TechMagnet I agree that Obrist would be better in terms of emissions now. But it's a form of settling. ICE technology is dead-end tech. While EVs as of now, may be less eco friendly that Obrist, it holds the promise of much lower net outputs in the future. Choosing plug-in hybrid tech is good enough, though when have we settled for good enough?
I actually did a little math. Tesla produce something around 11 tons of CO2 on 1 battery. That would leave you with 73g/km CO2 if you drive 15 000 km per year for 10 years. Assuming that 11 tons of CO2 is for long range battery with capacity 75 kWh + 5 kWh of unusable capacity that would mean that 137 500 grams of CO2 is required for 1kWh worth of capacity. This would mean 2.3 tons of C02 is produced on 1 Obrist battery (17.3 kWh). That leaves as with 15.9 grams of CO2 per km for 10 years(150 000 km) + 23 grams that is produced by petrol engine. Total CO2 emissions are 38.9g/km. So this means Obrist produce about 53% of emission of Tesla Model 3 (assuming that Tesla runs of 100% of clean energy which is for most places false claim). cs.wikipedia.org/wiki/Tesla_Model_3 eufactcheck.eu/factcheck/mostly-false-electric-cars-generate-higher-emissions-than-diesel-cars/ www.obrist-powertrain.com/hyperhybrid/
Very good idea and hope you guys will achieve your goals. But let´s keep in mind that CO2 is not a pollutant. CO2 is plant food, which produces O2 through photosynthezis. CO2 is only 0,004 % of our atmosphere and we need more of it, not less.
2 liters per 100 Km seems to be about 124 MPG. Excellent...and is not limited to only routes served by charging stations. I really think Obrist should avoid doing an exclusive deal with Tesla. They should offer this as an after market upgrade with a lot of electric car companies. I would imagine a Renault Clio, Captur, Cadjur with this system would get even better gas mileage and sell to a much larger demographic group than the high income Tesla owners.
They could reduce mobing parts by most by putnog inside gas alternator and gas turbines And sacreficing some of efficency but removing internal combustion process , its Type of flameless combustion where gases are heating them self below its temperature of ingnition in turbine generating electricity .
Put this in my Audi S4 and I’d have zero regrets. Sadly, EV tech and the compromises and limitations that come along with ownership just don’t make sense for most people I know. I’ve avoided Tesla as a result. On the other hand, 800+ miles of range in a hybrid would be a complete game changer. Not to mention the lifetime carbon benefits vs. EV’s. Bring it to the states. I’m in.
This is a Range Extender not hybrid since the ICE does not drive the wheels. I think the optimization of ICE power and battery size is interesting. IMHO, this is the best system.
Capacitors have very limited range. That being said there must be a use for them in regen braking, they are super efficient at charging and discharging quickly with miinimum round trip losses.
Ha! It would a nice thing. But I reckon it would cost more than a new Tesla, that being said I'd consider it for an old Tesla with a crapped out battery.
This really seems like the way to go. However, I wonder how long it will take for faster charging batteries to come online. If you can charge your car in 10 minutes or less, will this still gain traction in the automotive marketplace?
Well, the bigger the battery, the more miles you can recharge in the same time frame, fast charging still kills the battery, especially if it's too cold or too warm, so having it below 20% or above 80% charge for extended periods. Better battery tech is unfortunately a long way off. LiFePo4 can do many charge cycles, but it's not that energy dense, can't be charged or discharged as quickly but might be an option if it's supposed to last as long as the rest of the car.
The problem with fast charging batteries is you need the chargers to support them. You might be able to charge a 100 KWHr battery in 10minutes but getting a 600KW charger is another matter. Now imagine 8 of these in one place, that's 4MW. That kind of draw would probably put the lights out in my town.
@@Hamachingoare you aware that batteries have active thermal management? Also storing a battery at very low or very high SOC can cause degradation, but that isn’t what you do on a road trip.
This is a great hybrid electric vehicle. It would be great to market to those who drive ICE cars. But this is a terrible Tesla. It is much more destructive to the environment than a pure electric car. And you need to lie about BEV environmental impacts in order to make it sound better. Telling people that electric car "is not possible with the infrastructure today" is a great way to prevent them from adopting the cleanest available option. It's no different from what the oil industry is doing. It's also false.
Well Obrist are just next door to Germany where they're tearing up the forests for lignite mining. To supply the power stations. To power the Teslas. So Germany's maybe the world's 5th largest car market and Teslas there do come with an environmental cost.
This is just the next generation of the Chevrolet volt/Opel Ampera. That car also had 13.9 kwh usable, had a small engine whose main role was to assist the battery and held around 30 liters of fuel. They literally just copied the volt specifications and changed the engine to make it more fuel efficient with less electric range. This is not to say it's a bad idea, but I'm hoping they can actually get people to buy since the volt did not sell well and GM never made a profit on them. 🙁
Do you know what happened in the meantime with this concept. I tried out the link but it's not working anymore. Looks for me almost as this amazing concept that showed in real drive got somehow scrapped. I'm definitely completely convinced this would have a chance in car conversion or older electric cars with not enough range. Waiting for an update 😊
This could be good if for example batter size and density gets so low that you can cram let's say 40khw in the model 3 with this 2 litre engine. And make is so that the engine only kicks when the battery is really low or when on a road trip. Around town you can drive ans charge the model 3 like you do normally and still get 200 to 300 km of electric only range. Let's say you drove around town and have 50 percent battery and suddenly have to go really far that's when the engine can kick in. It would be very useful in big countries where people travel a lot. And would mean we dont need 100kw or bigger packs. Smaller batteries smaller waste and the engine being used rarely also means near zero emissions and massive range if needed. It's a i3 range extender but much better
Nailed it! Tesla purists may hate it, but everyone else sees a high performance car with brilliant fuel economy that you can charge at home should you wish.
This application seems ideal for commercial vehicles. And or I you could get in contact with Toyota. Try to combine your tech with their hydrogen tech for a full package solution. (Preferably without selling an exclusive deal to them).
I don’t get the hate. I love the concept. Power and speed of electric, the reliability and quick refueling of a gas motor. You get the best of both worlds. For those of you saying “who travels 1000km in one go anyways”. One word. Road trips. When your traveling long distances you wouldn’t want to be stuck at a super charger charging for two hours every 3 hours of driving.
I like the idea of this concept, too, but charging for 2h is not true, too. It is more about 20mins each 250km. The charging technology develops fast. The Taycan need 20mins to 80% and the upcoming Hyundai 45...more affordable...will charge to 80% in 15mins. Means, we will see who wins the race to market...this kind of technology or pure EVs. BUT...I assume both, since there was never a single solution for a complex problem. 😉
A better option would be to use a Microturbine Generator instead of any Internal Combustion Engine, smaller, lighter, maintenance and emissions free it would be able to fully power an EV while recharging the battery.
Orbrist should consider coming to Africa, where the eletric car resources and infrastructure are very little. With a great price tag 4 the model 3, i see how this might be a better solution for the combustion engines mostly found on African streets...
Absolutely. Might add that there's a ton of solar power in Africa. You could probably charge up this Tesla with roof top solar on your garage. Now granted that's probably beyond the budget of most Africans but it still cheaper than a an all electric Tesla in a country where you might only have electricity 10 hours a day.
Yeah it is but it's to late and the reasoning is stupid... With the upcoming gigafactory 4 near Berlin tesla cars Are goinging to get cheaper.... And Electric vehicle Are get ting better and better.... To put it short these Guys Are stupid and they can't beat tesla in anyway
Agreed, but Wrightspeed has not made any news or announcements for awhile. I wonder what the delays are. This tech could be used for almost all commercial vehicles right away...
Maybe they sold the technology to china. The way china be pumping out hybrid vehicles beats imagination. Only way is if the bought over the technology from other researchers
This is basically a model 3 with less preformance and less overall efficiancy, you also now have the added maintenance of a engine, all for a Prius conversion, also model 3 battery has a life span of 300-500k miles before hitting 80% original life, basically a life time worth of driving, this is a half measure that counters the market that buys BEVs it also makes it more likely that people will depend on gas stations then charging stations leading to a slow down in EV infastructure demand further delaying the inevitable switch to full BEV.
@Andrew_koala again, 300,000-500,000 miles of usable cells is 30 years worth of driving so people wont be replacing batteries because they drove them too much, what high cost maintenance? BEVs require less maintenance then anything else.
@@colinmacdonald1869 they are currently in the model 3, you can buy them online, they actually have a standard life span but the Tesla thermal management snd BMS system extends the life, people dont see in ther phones or computers go this long because the lack proper thermal management, they are now pushing a 1 million mile chemistry.
Stop being a no-compromise purist. This car will still pollute far less than an all-electric car and it's the answer for those who live in very rural areas, or areas where there aren't charging stations.
For all the Americans out there I did the math a couple ways just to be sure. When he says 2 liters per 100 km That adds up to over a hundred miles per gallon. That is insanely good gas mileage.
8:45. Energy consumption = 2L gasoline + 7.3kWh / 100km. With battery capacity 17.3kWh, it will be depleted in 237km. So, in order to get 1500km range, you wil need 30l gasoline + charging the battery from outside source every 237km. My point is that the title is misleading.
Imagine the looks filling up your Model 3 at a petrol station 😂
Wouldn't raise an eyebrow in my town. No-one quite believes that it only runs on electricity.
Hhm Theres a video a guy fuelling up a hybrid tesla
@@RandyTWester That's funny because o get the same reactions as well when they cant believe its fully electric..
@@RandyTWester Seeing how crap its range is when pressing the pedal to drive at highway speeds, it's definitely electric..
This is brilliant!! You have the efficient power and torque delivery of an electric motor, without range anxiety!! 2 liters / 100km is over 100 mpg. I want one!!!!
I don't get the hate. It's related to how a diesel electric freight train works. Engine is only running to recharge the batteries that run the car. No car has this technology, and to scale the technology down to the size of a car is impressive. Is it as efficient as a BEV? No. However, it gets around a major problem that BEV's have. You need to have a house, or someplace to charge a BEV, which is not always available outside of the major cities and first world countries. Not everyone is well off to own a house with solar panels, so this tech could help.
I understand the hate but I don't think it's warranted. Right now the cost per mile to drive this car is roughly the same as electric, except electric is getting cheaper and oil is getting more expensive.
Battery technology is going to keep improving to the point where they have the same range anyway, and infrastructure is only getting better. Right now this mostly solves the energy density problem, which means the concept is not really that useful for small passenger vehicles, but more for buses, trains, maybe airplanes and for transport semi trucks.
Actually the engine use as a charger, Chinese cars have this technology for a long time like the Li Auto L6,7,8,9 and AITO M5,7,9.
A great idea! I think this makes more sense than carrying a gigantic and heavy battery all the time. Also the excess heat from the generator will be used to heat the cabin which further increases total efficiency.
Heating a pure EV from cold used a big portion of the battery.
But perhaps they should use a microturbine as a generator. It has similar efficiency, but burns much cleaner (more complete combustion).
although I'd love to see a micro-turbine range extended EV for the novelty (see ERDEngineering's RX7 😆) ... even the smallest turbines produce incredible noise. It seems they might be better at maintaining battery charge in some continuous high-speed application, but not so good while starting and stopping in most driving situations. If accurate, 2L/100km is in the neighborhood of a Yamaha Zuma 50cc scooter - that would make biofuels or green gasoline actually sustainable (more efficient than sourcing electricity from the grid unless its coming from >50% renewable or nuclear sources).
Turbines are crazy compact yes, but they're not that efficient and they're only cleaner if you don't have an exhaust system which can't really be done on a turbine. Turbines are great if heat or power per weight is what you want, hence most modern diesels have one to get the actual engine up to temperature fast enough.
Linear generators or opposing pistons (2 pistons in the same cylinder) have potential, less moving parts and easier to pack. You can really optimise for efficiency if the engine can just run at its most efficient setting no matter what. Ideally allow it to pre-heat the batteries (less degradation) in the winter and use the gas engine as a heat sink for the battery coolant so it's already warmed up a bit before kicking on when exiting the city.
This is essentially an Eletric drive vehicle. The gas engine can be optimized to produce electricity. Hopefully Elon Musk is watching this video and will offer this as another Model option.
The extra heat from the generator can be used to heat the interior of the vehicle (like traditional ICE cars). That will in practice make it much more than 40% efficient. I really think this is the future. Especially for larger vehicles.
Yep, recycling the waste heat from the inevitable combustion losses is the right way to go, its how cars have been made for decades so its best to use a tried and true system :)
New batteries are on the way, within a few years the range will be over a 1000 km, a much lighter battery pack & recharge almost instant. Combustion is the past, biofuel is an awful idea.
@@nyali2 What is the material used for the new battery? Lithium is toxic
@@nyali2 what materials are used for the batteries? are they recyclable? what is the carbon footprint of their production? how safe are they? do you need to replace a whole pack or only a small unit when it gets damaged?
Just bc the car doesn't emit CO2 doesn't mean it's better for the environment overall.
A couple years ago a Range Rover with 5.0 V8 doing 17mpg was better for the environment than a Prius bc the Range Rover didn't require the battery pack.
A single cargo ship produces more CO2 and other green house gasses as 50 million cars.
Seventeen largest ships in the world produce more CO2 than ALL THE CARS IN THE WORLD COMBINED!
Having to ship massive quantities of lithium and rare earth metals doesn't seem like such a great idea in the light of this...
Apparently if we keep mining Lithium at the current rate it will take 10,000years to electrify the World's cars, trucks and buses. Of course we can open more mines, but we mine the easy stuff first, it'll get more difficult as we have to progress to lower grade deposits.
Absolutely freakin love this. THIS is the way forward for the developed world for cold regions, vast regions, and urban areas that lack home charging ability. This car will use so little fuel that it will produce negligible pollution, and the fuel can be expensive, synthetic, and renewably sourced. It won't matter.
The engine layout is good, but piston side forces could have been eliminated with rhombic drive. Mazda is working on a range extender rotary, which will have 3 moving parts and be the size of a large shoe box. Toyota is working on a free piston linear generator range extender. This is really the holy grail, the best of everything.
Sorry I’m American so I did the conversion,
he’s saying he has developed an engine that gets
120 miles per gallon?????
but isn’t mass producing it?? why??????
That's incredible!!!
and this is a WAY better hybrid system than most car manufactures currently have!!!
I love getting the benefits of both electric and gasoline!!!!
This is a range-extended electric, not a hybrid electric. That's not a valid comparison. VW had a 2 cyl diesel range extended concept that got over 200mpg over 10 years ago.
@@someotherdude And the fact that VW never decided to try to make a cheaper consumer version of the XL1 is baffling. There's no point going gas to electric cold turkey all at once, you need to wean society off of gas powered cars if that is even the ideal result, which it isn't, since high enough conversion efficiency from crops to gas to electric in cars is far higher overall efficiency than batteries, of which we're nearing the physical limit of capacity. The theoretical limit of NCA (Tesla) batteries is 274 mAh/g and the limit for Li-S batteries is 1675 mAh/g, and the gravimetric density changes based on discharge voltage, although Li-S has been found to have very low cycle life to not be viable.
Because it does not work as well as they say and/or no-one is interested
This makes perfect sense to me. Now I see a car that will work for me. I spend most of the working week driving about 50 miles a day. But on the weekends I drive about 100-200 miles a day, sometimes even 400.
As a model Y, I would actually love to get this installed! Best of both worlds. Full EV for local driving but when longer trips or even if you can’t charge at home.
Woohoo there are really alot of comments.. now here my opinion based on your input:
1) Its killing the purpose of EVs:
No its NOT. You can also drive pure electric and you still drive pure electric. the engine is just recharging the battery. You need to understand that the engine is HIGHLY efficicent. Usually fuel engines have max 35% efficiency and during accelerating they run in load ranges that are not the optimum. This engine always runs in perfect conditions with 40% efficieny. Thus its VERY environmental friendly.
2) Its stupid because you now have more maintenance:
Wrong - the engine concept is super basic. No timing belt to change. all maintenance would be somtimes new plugs, an oil change, maybe filters. How long does it take.. maybe 30mins ? costs ? almost nothing.. The benefits having this engine are clearly higher than the downside of maintenance
3) Range
Well 1500KM with 30L is correct - watch the interview at 14:30. If you charge the battery every 1-2 days you get 1500km out of 30L. in fact range on a single trip would be 800. This 1,500-km range comes with a fully charged battery pack. It is equivalent to being able to run a little more than 930 miles on a tank. The 700-km (436-mi) range shows up in the worst-case scenario: a depleted battery and running the car solely at high speeds!
4)It does not help the environment
In fact in mass it does more than a tesla. Full EV is not possible with the infrastructure today. To get CO2 QUICKLY down we need this concept to roll out EV quickly to the masses. Charging infrastructure is not ready yet and also production of EVs is too expensive right now to make this technology ready for the masses. As said in this video. You could get an electric car with this concept for 20.000 EUR - Look at the prices Tesla is charging - Who is able to afford this ? Def. not the average people out there... It would be a bigger benefit for the environment to get all cars down to 2L / 100km instead of driving a few EVs which are not changing anything in the real world statistics of CO2 emission... And think about Bio fuels... when you just need 2L per 100KM then more expensive biofuels make sense!!
I completely agree with you and think this is a brilliant idea for an average person.
40percent efficiency on fuel? Are you a fucking coal plant?
most gasoline combustion engines average around 20 percent thermal efficiency....
It's a hybrid EV and I think this is a brilliant idea because u can add a really long range and there is another reason that this kind of idea is more suitable for some country's like here in my country we are not allowed to import EV's because there is no infrastructure for it so we need this kind of technology in my opinion
Nice video by the way 👍
Nice point.... But I think that they should had use a hydrogen engine (i don't know anything about it but they Are avle to use it in cars) and solar roof just an idea and the time that Eva get to evert country i think that there should be a network in You're country to
@music hald: even on a bright sunny day a solar roof charges only 1km per hour
Hybrids usually mean there is a physical mechanical connection between the engine and the wheels which this doesn't have.
finally! was looking for a video on this topic
oil change? maintenance for the engine??
This is good for countries with poor power grid. Generator onboard. No need to look for a external power source
Exactly. I might also add that pretty much every country's grid would have difficulty handling an all electric fleet. I take it you live in Africa? An all electric car might actually work better there than here, you could conceivably charge the battery from solar panels on a roof, possibly economic in the tropics where you get really strong sunlight, but certainly not here in Scotland, though that doesn't stop green halfwits promoting it.
I understand that this is a more affordable car right now, but instead of wasting our time on this and work on better battery technology than we can achieve affordable ev cars, the right way.
So you are saying: lets wait another decade?
Batteries will be expensive if (and this is a big if) batteries will be good enough to overcome the problems of the batteries we are experiencing today.
@@hermanstokbrood no what we are saying is the concept is stupid. Had this been a hydrogen fuel cell technology I could understand it. But this takes an efficient design gives it the middle finger and slaps you in the face.
Oh, lets put a generator in an electric car. Thats not stupid at all. If you want smarter rig a flywheel off each wheel and charge it that way.
@@jamesirwin7677 Waiting for better batteries seems to me a waste of time. So we have to think of something better in the meantime. Hydrogen fuel cell technology isn't efficient at all. It looses to much energy just by making it. You can't fill your tank everywhere either which is even a bigger no-no for most people.
Don't get me wrong, I don't think this solution is the best we can come up with but it is a step in the good direction and we can do it now waiting for better batteries to come.
That's assuming that we can significantly improve the battery tech. We probably need to double the power density and halve the price for all electric cars to go mainstream. In any case we would still have a huge cost to upgrade our electricity infrastructure to accommodate these new batteries. Do you think its feasible to charge a 100kwhr battery in the same time it takes to fill your gas tank? 1 MW charger anybody!?
@@colinmacdonald1869 Yeah, better batteries don't grow on trees. Graphene seems to be the solution but this is promised to be the holy grail for a decade by now. Progress is very slow.
So, I think this company is walking the right path for now. Don't waste time just waiting for batteries that might never be good enough for the masses.
I thank Elon Musk to be bold enough to start Tesla. It isn't the perfect car yet but the Model 3 was the best selling car in my country for 2019. Just because the government knows their priority.
We have still a way to go but all new companies coming with any solution is better than none.
What is the power of your engine ? Did you consider using it for a power backup generator ? If it is really so quiet and smooth you will blow the competition in North America out of water if you can sell it for a competitive price.
I love the concept. For America, I would like to see it in a minivan with 75-100 mile battery range. That would cover virtually all urban use as a pure EV, while offering no stress, zero compromise family vacation travel at 50+ mpg. Even light towing! Not mentioned in the video is the fact that this system can eliminate all the cold weather disadvantages of pure BEVs.
Best hybrid concept ive seen in years.
VW XL1
I agree, seems like a level up in hybrid technology. I always believe that hybrid cars is the transitional technology period to full electric, with every country moving into sustainability in my opinion is the best way to transition into full electric while weening off Petro, but in the political world seems like they are pushing everyone into electric the wrong ways with little to no transitional period for the technology to catch up.
Did you do it?
I’ve a ‘21 M3 on over 100k would do this but would rather convert my other vehicles to range extenders first.
It’s great but would surely void most warranties.
Fantastic idea that should have been standard when it was implemented a century ago with the 1916 Owen Magnetic. Definitely the best solution for today eliminating range anxiety, speeding up refueling times and reducing the heavy and expensive battery found in full B.E.V.
Next best " new" thing mini nuklear powerplant range 25 years of running 😁
I can see them making cars that will be fully recyclable and batteries that will last many years without worry of needing a change for the life of the car.
You guys don't get the point...
This would allow to make cheaper electric cars!
Smaller battery, greater range = less cost of production, less cost of buying
All of you complaining about how this is burning folli fuels, while in reality this would just simplify the switch to electric cars.
And is there a update on the results?
This is not a Prius, but is exactly like the Chevrolet Volt, which is an electric vehicle with an onboard gas generator range extender. Not a new concept, Chevrolet did it from 2011 to 2019.
This car actually proves how bad current petrol cars currently are.
It's appearantly capeble of driving a 1000km with just 30 liters of petrol.
Call me any petrol car that can do that and remember, a model 3 is not the smallest car at all.
Where do you get 30 liters of petrol, 2 liters/100 Km means 20 not 30 liters per 1000 Km.
30 litres of petrol and a full battery.
This will work great if they can make a plug-n-play version of it ….I.e. don’t remove Tesla battery or change any of Tesla electronics - connect up to extender to the existing charging circuit and price it under 5000 Euros + maybe another 1000 Euros for installation. This can just act as a power plant when car is not moving and thus eliminate all range anxiety as we can then charge it anywhere and not worry about availability of ev chargers.
This is the best transition to EV.
I really like the concept of a Extended Range EV, especially in North America.
If 90% lf the time you drive less tha 100 miles per day, why don't share all the lithium between 2 or 3 cars with an extended range when needed.
no, the best transition is made by : transition one, a French company
So basically it is a hybrid car.
Cost? Availability?
I like it. It is a Prius plug-in with 2.5x more efficient ICE and stronger electric motors. 2l per 100km vs 5 l/100km.
I just don't like the idea of exhaust ending in front of the cabin. I wouldn't like increased risk of being poisoned by fumes.
Then I'm sure you never drive behind other vehicles.
Damn, people are haters. How is no one impressed with the range! It'd astounding how far that can go. From a cost standpoint from the customers, it must be cheaper to fill up the tank for the constant recharging than to re charge a Tesla battery 3-4 times thus saving time and money!
Basically a prius
🤦♂️
@@thomasr.5022 Next, they'll get rid of the battery and call it a gasoline powered car.
Clearly didn’t understand it :D
It has a plug, thus it's a Prius Prime.
Prius with one 1 liter petrol only cover 30 km
Very curious how you got past all the software lockouts and safeties to charge the battery while driving
It's a hybrid. Yes better than a standard car but nothing new. If it had come out 10 years ago then it would have been worth considering.
chevy volt has been doing this long time ago, simply its a "range extender"
This would also be perfect for CO2 neutral synthetic fuels.
Yep that's exactly it. This is a whole nother ball game
I wished serious production of this was happening as fast as possible. Like teaming up with a German car company and start production in a year or two seeing as this video is a year old
would be nice if they would make something that weighs about 150lbs and puts out about 10kw that fits on a trailer hitch to give any electric car a bit more range.
Da gibt es als Themen einmal eine Vorstellung des Generators, dessen Laufgeräusch und -ruhe,
aber vor allem das Arbeitsprinzip, denn in einer Animation waren 2 gegenläufig rotierende Zylinder mit 2x 20 kW Generatoren zu sehen, die ja reichen würden, den E-Motor direkt anzutreiben
Nehmen wir an, die 40 kW liegen im Drehzahloptimum zu 95% vor, dann wären es 38 kW.
Wozu braucht der Hybrid dann noch 7 kW aus dem Akku oder läuft der Wagen im Standardbetrieb mit 20 kW und die 7 kW on Top aus der Batterie bringen dann gesamt 27,5 kW für grob 150 km / h im model 3 auf die Straße und mit leerem Akku gäbe es eine weitere Reichweite von bis 800 km, dann aber limitiert auf max 20 kW, was im model 3 wohl 125 km/h entspräche.
Die 2 Liter Diesel haben grob als 2 kg Diesel einen Energiegehalt von 22 kWh ... nur wie kann das bei 40% Effizienz oder 8,8 kW für 1h Betrieb reichen, wie es das Generator Video zeigte.
Eins bleibt ja dann immerhin kein Thema: Heizen im Winter kosten dann keine Reichweite mehr.
Jedenfalls ist der 2 Zylinder Generator mit grob 20cm Tiefe und 70 Breite x 50 cm kompakt und sehr leistungsstark geraten verglichen mit Honda Notstrom Aggregaten.
An sich erinnert mich das an den alten U-Boot Konzeptantrieb aus dem 2. WK.
Great idea ... currently we use 2 cars ... a bev for 250 km radius and a blue efficiency diesel.
Our first bev sucked from day 1 ... a tesla that had issues from day one. 400 km for each try to fix it cause Tesla service center are too far away. Now we have 4 service stations within 20km but this car does not need a repair... cause it simply runs ... or charges cause range is the missing point of the new, but if range matters our Mercedes blue efficiency Diesel is unbeatable.
BMW i3 had a similiar range extender concept ... but did not succeed ...
The BMW effort is just awful, but BMW has completely lost its way. The reliability issues (electrical) are a shit show.
The thing I love about having a combustion range extender is that you can use the excess heat to heat up the cabin (thus dramatically increasing total efficiency). Also, the lower total weight means the tires wear longer and don't produce so much rubber pollution and airborne dust.
Perhaps a microturbine would be even better as a range extender because it burns the fuel more completely and thus emits a much cleaner exhaust gas.
Modern Teslas use a heat pump to cool the battery pack, there is a fair amount of waste heat in a 100KWhr pack. You probably only need 500W to heat a car, that being said if you're talking about heating s car in Iowa, January, there probably isn't any waste heat and the battery has problem lost 50% of it's range coz it's cold.
How disappointed i am when seeing this video today....reason, i had this idea 3 days ago ....calculated how this was way way efficient and cheap to make ...also had this idea if only it would be possible to have an alternator that with 10% input gives out 100% output...this is a game changer...if only it would be possible , which it is but the tech is years to come with major breakthrough.. Got this idea, but its already showed up..Big Thumbs up to this guys..this is great news and happy that someone actually thought of it....This is the next tech that consumers don't even know yet how best it will suit them.✨💯🇰🇪
Ha! I had the same idea years ago, I hate parallel hybrids they're just messy and complicated, I've been wondering why nobody has tried using a teensy weensy engine to charge a battery and then just run an e motor. My reasoning being I only 10% of the power 90% of the time. Only could find one serial hybrid, the now defunct Fisker. Then I stumbled on this completely by accident.
SPOILER ALERT: ITS A HYBRID
Not really a better Model 3 🤔
It's actually a Worse Model 3

Discharging and charging a small battery like that will degree the lifespan of the battery.
But!
Since it’s a small battery, they can be purchased or replace for a small fraction. Not often tho.
So yes, 2 liters for 100km is revolutionary. It’s actually cost effective and ensures your trip.
Hybrid is the way to go.
That’s the point bro. They keep the battery percentage up it will never fully discharge. Only partially
I can see Tesla coming after them with a Blank Check
Hahahaha yes !!! Repost and Tag Elon musk on Twitter 😂😂😂
Now this is great but how do they get the car to run on 7kWh/100km? AFAIK you're lucky if you get 15kWh/100km
This is what the prius should have been, a electric gasoline hybrid. I mean it's a great idea a plug in for short trips with the optimized generator for longer trips .
But it feels a bit late to the game and it's not new tech, trains have been doing this for a while now.
I find it funny how we kept throwing train and marine technology at cars and then diesel-electric was kind of forgotten in the automotive industry. We had steam trains and chucked steam at cars only to find out it was either not very good or we couldn't make it good enough, then we took other tech and decided to throw motors from grid-powered machinery at cars and realized batteries were super heavy and sucked, so we went all-gas. Then nearly a century later we decided electric was good enough and we've forgotten about gas at the sacrifice of personal independence and range. For use in a city with short trips you only need maybe 80 miles not 400, so that's 80% less battery weight, and a lightweight gas generator plus fuel is far less than the weight that was saved, so 80 miles battery-only range becomes maybe 85 instead. Once again public opinion, marketing and politics have ruined progress.
Edit: The average driving distance in an urban environment is around 36 miles per day. So 80 miles even is overkill :P
The large companies have large off the shelf engines.
This one of the greatest innovations made we just dont know it yet

Good success with your system!
Sebas M yea we got some good engineers here! Thanks mate :)
Hybrids have too many compromise just to have further range. Safety and speed are some of them.
Well I thought you rerouted HVAC system to use waste heat of the petrol engine. Reduced battery size also makes the motor less powerful. Basically devalue the vehicle. It's proof of concept alright but it's a really old concept, Prius is demonstrating it everyday on the street.
If you would do more research, you will know that its not the same as a Prius! Knowledge is power!
@@honeybee0414 lol what is the most power they can get out of a 17kWh battery this is similar to the defunct fisker karma... Performance is not scalable ... this is only suitable for an econo car not a platform that can compete with ICE performance vehicles
The prius is not a range-extended vehicle. You're not making a valid comparison.
I'm still waiting patiently for a Obrist package for retrofitting to existing Petrol and Diesel powered vehicles. Imagine if I am able to properly convert a commercial vehicle or even a recreation vehicle for this purpose.
Replacing existing internal combustion only powered vehicles with this "Hyper Hybrid" concept is exceptional and will help us meet our carbon goals before 2050.
I love it. I just wish there was a trailor version for my Rav4. It only goes 65 miles till I have to stop and recharge. I wish there was a way to hook up this system in a trailer in back to extend the range. I have seen another car built to do that. Looking for a range extender for my EV.
The coins were glued to the valve covers 😂😂
so basically a step backwards? what a joke. EVs not only help the environment but the whole point is to avoid the gas and maintenance costs that come with gas cars. Honestly, how can you be serious about this? fast charging is the way to address range. not this nonsense with hybrids.
On a longterm yes. But who has EVs right now? People who have to money to afford them. But who emits the most co2 ? Yes the people who can’t afford crazy prices Tesla or others charge. To quickly get co2 down there is no way around super efficient hybrids. Infrastructure can’t be changed that fast.

This is such a step backwards, it's hilarious.
@@Andrew-eg7fy i think he was payed.
@techmagnet, I'm sorry for all the people that don't understand this. Great video mate!
Thanks for the heads up mate :)
Great! We need these in vans, NOW!
So basically a bmw i3REX
This would be perfect for general aviation .
Well, they could update the engine with the 55% efficient SkyActivX or perhaps wait for the 65% efficient LiquidPiston engine once it reaches production now that they aren't tied up with what I believe was a military contract. Also replace the battery entirely with supercapacitors or sodium-ion to eliminate the use of lithium-cobalt and therefore greatly reduce the production carbon footprint of the car. It takes a few dozens of thousands of kilometers before any Tesla breaks even with a vehicle like a 3rd or 4th gen Mazda3, and even then the battery has already lost at least a tenth of its original range, perhaps more depending on charging habits and how much "fun-having" you do, aka time at WOT, as well as weather conditions since equatorial or arctic weather (the latter being me up here in the tundra-like-winters of Ontario) damages the battery, the former overheats and overstresses the lithium while the latter reduces range and therefore increases the charge cycles which reduces lifespan. Its all complex, so you might as well cut out the more chemically complex bits and use the simplistic and efficient creations of our forefathers rather than reinventing the wheel.
This is exactly what I would want here in the US 🇺🇸
Love it, best of the best, I would love to have that technology available in the states
Congrats! you built a Chevy volt! People are trading in Kias to buy a model 3 so price isnt the biggest issue. At least not in my part of the world where people will pay 80,000 + for a pickup truck. Good concept but 5 to ten years too late. Bevs are the future. To me it just dosnt make
sense to haul 2 power trains around to get where you are going. I hope Teslas battery day will put all this hybrid stuff to rest.
Yea and yours or my part of the world are small compared to the India where EVs just exist on the paper. Still we are living on the same planet and getting CO2 down with EVs is something to dream about. Chevy volt is different though. When the engine is running it may be periodically mechanically linked (by a clutch) to a planetary gear set, and hence the output axle. Emitting way more pollutants than this just acting as a generator
I'm sorry guys, it's a flawed concept. It introduces more complexity for virtually 0 gain. How often do you need to drive 1000km in 1 go? Be honest.
Would say that depends where u live. Not all people live in the city. When u are in the city how often do you need a car at all ?
@@TechMagnet würde ich nicht sagen....ich feier deine Videos nornalerweise, aber das war wohl nix!
@@TechMagnet so you live 1000 kilometres from the next city 😂😂?
@@ForChiddlers yeah...thought the same!
Do you really need 250miles EV battery when you charge every day?
Great, let's convert electric zero emission cars to fossil burning cars, LOL.
Look at how many cars Tesla has sold. U think that makes an impact ? With those huge batteries Tesla is using the carbon fibre footprint doesn’t look good aswell. And if u can bring the majority of cars down to 2L this makes more a difference than all units Tesla sold so far.
you're braindead
@@TechMagnet I agree that Obrist would be better in terms of emissions now. But it's a form of settling.
ICE technology is dead-end tech. While EVs as of now, may be less eco friendly that Obrist, it holds the promise of much lower net outputs in the future.
Choosing plug-in hybrid tech is good enough, though when have we settled for good enough?
I actually did a little math. Tesla produce something around 11 tons of CO2 on 1 battery. That would leave you with 73g/km CO2 if you drive 15 000 km per year for 10 years. Assuming that 11 tons of CO2 is for long range battery with capacity 75 kWh + 5 kWh of unusable capacity that would mean that 137 500 grams of CO2 is required for 1kWh worth of capacity. This would mean 2.3 tons of C02 is produced on 1 Obrist battery (17.3 kWh). That leaves as with 15.9 grams of CO2 per km for 10 years(150 000 km) + 23 grams that is produced by petrol engine. Total CO2 emissions are 38.9g/km. So this means Obrist produce about 53% of emission of Tesla Model 3 (assuming that Tesla runs of 100% of clean energy which is for most places false claim).

This is good to make gas cars more efficient not to convert electric cars. So they should target big manufacturer with this concept.
Very good idea and hope you guys will achieve your goals. But let´s keep in mind that CO2 is not a pollutant. CO2 is plant food, which produces O2 through photosynthezis. CO2 is only 0,004 % of our atmosphere and we need more of it, not less.
Great Idea, but can it be put in without having to take out the original battery, like an aftermarket kit ?
makes sense to me. have 50-150miles of ev range and a small generator to charge/maintain the battery when needed.
Range extended trucks is the market they need to go after. The added complexity in a truck is ok. For cars going full electric is the way forward.
2 liters per 100 Km seems to be about 124 MPG. Excellent...and is not limited to only routes served by charging stations.
I really think Obrist should avoid doing an exclusive deal with Tesla. They should offer this as an after market upgrade with a lot of electric car companies. I would imagine a Renault Clio, Captur, Cadjur with this system would get even better gas mileage and sell to a much larger demographic group than the high income Tesla owners.
They could reduce mobing parts by most by putnog inside gas alternator and gas turbines And sacreficing some of efficency but removing internal combustion process , its Type of flameless combustion where gases are heating them self below its temperature of ingnition in turbine generating electricity .
Put this in my Audi S4 and I’d have zero regrets. Sadly, EV tech and the compromises and limitations that come along with ownership just don’t make sense for most people I know. I’ve avoided Tesla as a result. On the other hand, 800+ miles of range in a hybrid would be a complete game changer. Not to mention the lifetime carbon benefits vs. EV’s. Bring it to the states. I’m in.
great video, thanks.
This is a Range Extender not hybrid since the ICE does not drive the wheels. I think the optimization of ICE power and battery size is interesting.
IMHO, this is the best system.
So my question is, can you take the batteries out of the equation? Maybe just use a capacitor?
Capacitors have very limited range. That being said there must be a use for them in regen braking, they are super efficient at charging and discharging quickly with miinimum round trip losses.
Want this in a 4wd pickup/ bigger engine that runs episodically as needed
When will this be available in the USA? Also, this would be really cool if a conversion kit for used Tesla models can be offered.
Ha! It would a nice thing. But I reckon it would cost more than a new Tesla, that being said I'd consider it for an old Tesla with a crapped out battery.
How much does the Orbist cost??? Especially to install in the Model 3? Also do the sell the Mark II... Alrrady installed and for how much?
Its a development company. I think they just sell their patents and licenses.
This really seems like the way to go. However, I wonder how long it will take for faster charging batteries to come online. If you can charge your car in 10 minutes or less, will this still gain traction in the automotive marketplace?
Well, the bigger the battery, the more miles you can recharge in the same time frame, fast charging still kills the battery, especially if it's too cold or too warm, so having it below 20% or above 80% charge for extended periods. Better battery tech is unfortunately a long way off. LiFePo4 can do many charge cycles, but it's not that energy dense, can't be charged or discharged as quickly but might be an option if it's supposed to last as long as the rest of the car.
The problem with fast charging batteries is you need the chargers to support them. You might be able to charge a 100 KWHr battery in 10minutes but getting a 600KW charger is another matter. Now imagine 8 of these in one place, that's 4MW. That kind of draw would probably put the lights out in my town.
@@colinmacdonald5732 Excellent point.
@@Hamachingoare you aware that batteries have active thermal management? Also storing a battery at very low or very high SOC can cause degradation, but that isn’t what you do on a road trip.
Do you need to fully charge the battery on the power station or it can be solely charged by the engine?
This is a great hybrid electric vehicle. It would be great to market to those who drive ICE cars.
But this is a terrible Tesla. It is much more destructive to the environment than a pure electric car. And you need to lie about BEV environmental impacts in order to make it sound better. Telling people that electric car "is not possible with the infrastructure today" is a great way to prevent them from adopting the cleanest available option. It's no different from what the oil industry is doing. It's also false.
Well Obrist are just next door to Germany where they're tearing up the forests for lignite mining. To supply the power stations. To power the Teslas. So Germany's maybe the world's 5th largest car market and Teslas there do come with an environmental cost.
This is just the next generation of the Chevrolet volt/Opel Ampera. That car also had 13.9 kwh usable, had a small engine whose main role was to assist the battery and held around 30 liters of fuel. They literally just copied the volt specifications and changed the engine to make it more fuel efficient with less electric range. This is not to say it's a bad idea, but I'm hoping they can actually get people to buy since the volt did not sell well and GM never made a profit on them. 🙁
Yup, it's a high-end bolt.
My 2016 sonata plugin does this already. Nothing new here.
Your sonata using 2L gas on 100KM??? hehehe .... YAH WHRITE :-)
Do you know what happened in the meantime with this concept. I tried out the link but it's not working anymore. Looks for me almost as this amazing concept that showed in real drive got somehow scrapped. I'm definitely completely convinced this would have a chance in car conversion or older electric cars with not enough range. Waiting for an update 😊
This could be good if for example batter size and density gets so low that you can cram let's say 40khw in the model 3 with this 2 litre engine. And make is so that the engine only kicks when the battery is really low or when on a road trip. Around town you can drive ans charge the model 3 like you do normally and still get 200 to 300 km of electric only range. Let's say you drove around town and have 50 percent battery and suddenly have to go really far that's when the engine can kick in. It would be very useful in big countries where people travel a lot. And would mean we dont need 100kw or bigger packs. Smaller batteries smaller waste and the engine being used rarely also means near zero emissions and massive range if needed. It's a i3 range extender but much better
Nailed it! Tesla purists may hate it, but everyone else sees a high performance car with brilliant fuel economy that you can charge at home should you wish.
This application seems ideal for commercial vehicles. And or I you could get in contact with Toyota. Try to combine your tech with their hydrogen tech for a full package solution. (Preferably without selling an exclusive deal to them).
I don’t get the hate. I love the concept. Power and speed of electric, the reliability and quick refueling of a gas motor. You get the best of both worlds. For those of you saying “who travels 1000km in one go anyways”. One word. Road trips. When your traveling long distances you wouldn’t want to be stuck at a super charger charging for two hours every 3 hours of driving.
I like the idea of this concept, too, but charging for 2h is not true, too. It is more about 20mins each 250km.
The charging technology develops fast. The Taycan need 20mins to 80% and the upcoming Hyundai 45...more affordable...will charge to 80% in 15mins.
Means, we will see who wins the race to market...this kind of technology or pure EVs.
BUT...I assume both, since there was never a single solution for a complex problem. 😉
How much the Orbist cost?
A better option would be to use a Microturbine Generator instead of any Internal Combustion Engine, smaller, lighter, maintenance and emissions free it would be able to fully power an EV while recharging the battery.
But Noise and Vibration
What if we make some kind a generator that you use when you go long trips.
Fantastic job 👏👏👏👏
And a useless one
Orbrist should consider coming to Africa, where the eletric car resources and infrastructure are very little. With a great price tag 4 the model 3, i see how this might be a better solution for the combustion engines mostly found on African streets...
Absolutely. Might add that there's a ton of solar power in Africa. You could probably charge up this Tesla with roof top solar on your garage. Now granted that's probably beyond the budget of most Africans but it still cheaper than a an all electric Tesla in a country where you might only have electricity 10 hours a day.
love your channel just subscribed
This is a great concept!!
Yeah it is but it's to late and the reasoning is stupid... With the upcoming gigafactory 4 near Berlin tesla cars Are goinging to get cheaper.... And Electric vehicle Are get ting better and better.... To put it short these Guys Are stupid and they can't beat tesla in anyway
I want to see a 6hp Lister Diesel sticking out of the hood running all day on Peanut Oil while I'm at work.
I think a turbine generator burns cleaner than a regular piston generator. Check out Wrightspeed.
Agreed, but Wrightspeed has not made any news or announcements for awhile. I wonder what the delays are. This tech could be used for almost all commercial vehicles right away...
All Nissan Leaf needs this engine to keep them on the road. how can I get one for mine?
5 years past, and then where are them? not a single car like that. who stop them?
Maybe they sold the technology to china.
The way china be pumping out hybrid vehicles beats imagination.
Only way is if the bought over the technology from other researchers
Maybe tesla sued them
No,they didn't.
This is basically a model 3 with less preformance and less overall efficiancy, you also now have the added maintenance of a engine, all for a Prius conversion, also model 3 battery has a life span of 300-500k miles before hitting 80% original life, basically a life time worth of driving, this is a half measure that counters the market that buys BEVs it also makes it more likely that people will depend on gas stations then charging stations leading to a slow down in EV infastructure demand further delaying the inevitable switch to full BEV.
@Andrew_koala again, 300,000-500,000 miles of usable cells is 30 years worth of driving so people wont be replacing batteries because they drove them too much, what high cost maintenance? BEVs require less maintenance then anything else.
Wow, I want these cells NOW! Where can I get them? Elon's fantasy crystal Mars base perhaps!?
@@colinmacdonald1869 they are currently in the model 3, you can buy them online, they actually have a standard life span but the Tesla thermal management snd BMS system extends the life, people dont see in ther phones or computers go this long because the lack proper thermal management, they are now pushing a 1 million mile chemistry.
all the ICE cars disadvantages come to the model 3 now.
Stop being a no-compromise purist. This car will still pollute far less than an all-electric car and it's the answer for those who live in very rural areas, or areas where there aren't charging stations.
For all the Americans out there I did the math a couple ways just to be sure. When he says 2 liters per 100 km That adds up to over a hundred miles per gallon. That is insanely good gas mileage.
