- ( www.TFLcar.com ) How far can a car go on one gallon of gas? That's the competition that University of Colorado Mechanic Engineering students will be taking on later this month as they go and compete at the annual Shell Eco-Marathon in Texas.
You can learn more on their team's Facebook page: / cubouldershellecomarat...
Roman recently caught up with CU's team as they were doing some fine tuning and found out for himself the secrets you need to know if you want a car to get a real world 1767 MPG.

So many people here are completely missing the point of this. Programs like this are less about the vehicles consumer potential and more about training the engineers of tomorrow. Obviously from what was said they are using whatever is at hand which in turn breeds ingenuity.
Just look at the guys from Virginia Tech and what they've been doing with their electric motorcycle. They're successfully competing against the likes of Honda and Yamaha who are working with astronomical budgets. Personalty, I think project like this are a great idea,
The proble is that consumers should focus on this.
This has incredibly good consume potential for me if it gets solar panels and a eletric engine, preferably with option for pedal power.
I bet if the wheels didn't have spokes these cars could squeeze out an extra 40 or so mpg. Or if they put something that covered the spokes, because they do have a lot more air resistance than people think.
CockatooDude that’s additional rotational mass though, and at that speed the need for wheel covers aren’t that important
thesuch low speed probably will make it so the aerodynamics wont matter

I met a man who built a 3-seat all electric trike that goes steady 45 MPH on just sunlight - no fuel/engine at all, street legal.
Would win this event hands down. Build cost $8,000
hi ,tell me more about that gay ,woul be great to learn something like that
There are different fuel classes. That vehicle would be ineligible.
I don’t believe you. The instantaneous power required to move 45 mph would need a solar panel the size of a houseroof. (Therefore impossible to carry on the motorcycle.)
oh
@@electrictroy2010 I met Larry at Daytona several years ago. The instantaneous power comes from 3 Marine lead-acids.
By now, Lithiums would be affordable.
The batteries also allow night-time driving.

Imagine the possibilities of where you could go with a platform like this though. Use a hybrid drive system, cover the thing in flexible solar panels, rig up a tiny little turbocharger, and a lightweight air conditioning unit for basic comfort.... If you didn't have to worry about getting run over, you'd have a little runabout that could get you to work and back on like a gallon or two a week. Hook up a little streamlined trailer and you could go on road trips for a couple bucks' worth of gas.
The funny part is we have so many safety regulations forcing our vehicles to be so heavy but we could achieve amazing MPG with current engines if the cars were lighter.
This is true.
And I bet they could make em pretty safe and light but that would make less money perhaps. A caterham . Mass produced. 50hp only. Boxes and crumple zone between wheels or perhaps a whole new solution like a small protective cage around the seat that comes down or an airbag donut. And honestly I'd have no issue with a half face helmet
And hell I'd be fine with being risky a bit now. I think making a caterham considerably safer could be done for 500bucks 50kg easily enough. If those had the economy of scale of a ford focus and healthy competition in the concept thered be plenty of them. Aero clear plastic shell around too.
tens of thousands dying but look how much I saved on gas!
Hard working individuals like these graduates will help change the worlds transportation problem.
lol... you said "change the worlds transportation problem." not "solve" so that would imply they would create a problem if they have their way, which maybe true as this thing is slower than a bicycle
Solve
CatcherOfBass there is already a ton of solutions and some of the systems in huge cities already work so its not really a big issue.... but its good they are doing this as it will advance us in car tech (i know a bicycle is more practical, more green and faster than this but this is how the car as we know it today started off life)........ given time they might actually help in developing a truly efficient full size car that people can actually use
not if the oil giants keep having there say
@@dunhillsupramk3 You have to get rid of big oil...
The fuel economy's fine, but can it do a burnout ?
Was that supposed to be an attempt at a joke? Either way you’re an idiot.
Top Secret why be so mean
@@topsecret1837 Yes, it was obviously my attempt at a joke, and my idiocy is a matter of public record. So, all things considered, your comment was pointless. But, never mind, you tried your hardest. So, well done, you get top marks for trying.👍👍👍
Yes if you try it hard enough
@@CalculatorGuides Good point.👍👍👍
Surprised they weren't running some sort of high end aero wheels like Zipps or HEDs given how important drag would be to something as low margin as this.
Zipps w/ Ceramic Speed bearings are used in competition but standard wheels are used for testing
***** Blech. Hybrid bearings?
Filthy casuals.
4:35 And oh boy when it does work it puts a smiley grin on your face.
If it doesn't, more tests and hypothesis. I'm the same.
No bladed spokes or aero rims. Bit of an oversight.
You know what, you’ve got a great point. If I were to change this I would have reversed the wheel orientation so that there would be 2 rear wheels and one front wheel. Same number of wheels, but all three wheels can be embedded into the body of the vehicle. And with that it could be improved; all it would need then is a low center of mass and it won’t be unstable.
@@topsecret1837 Look at Velomobiles. The best aerodynamic arrangement is 2 wheels fwd and one aft and you can still embed them perfectly in the body. Best examples are the Milan SL or the After7 which are both incredible efficient Velomobiles.
Probably needs two front wheels to be classified as a car
Very cool...hope they have a real world challenge for these students...something that can actually go hiway speeds & have a passenger...
Drinking game: take a shot every time he starts a sentence with the word "So"
+Brian McKenna That's OK, I don't feel like commuting suicide today.
so I'm wasted now so far so that's good.
Cool and very interesting!
Smart young Americans... I love it !
Can It go uphill or handle any bumpy road
Top speed?
We managed 1760mpg with an AC1 lister diesel at Silverstone UK in 1993
Using Avid BB7 brakes made me laugh a bit.
I wonder if they could increase fuel efficiency by running these on rails rather than roads to really reduce roll friction, and also... why not feed compressed oxygen into the engine for standard performance in all altitudes rather than keep re-tuning every time you relocate for a race? That way if you do cross the country you don't have to re-tune based on altitude as you go, you just go.
the rails would be best to make a train, and the tuning for air, is that its a 35 cc engine, really small, and it takes energy to run a supercharger, and a turbo wouldn't get enough exhaust. They literary just put a motor on a recumbent reverse trike. search battle mountain velo.
But how fuel efficient is it when the engine is always on, like most cars, realistically are?
Same sound effects as Veritasium? or is it the other way around..
I noticed that too! If I had to guess, I'd say it's probably a royalty-free sound effect from UA-cam that Veritasium happened to make famous.
The oil companies would sure fight to keep these off the road if they were built for the public or they might just jack up the price of gas.
Must be why it's called the "Shell Eco-Marathon". To make sure that those kind of (probably copyrigthed) ideas never get near an assembly line by controlling it at the source. Clever.
Lol just buy a motorcycle
Ben Gagnon
They’re probably not copyrighted. And what if hypothetically someone created a vehicle that was roughly like these but could be homebuilt either from scratch, by parts kit or a full vehicle? I’m thinking up of something like these based on a normally pedaled vehicle called velomobiles.
So when do you get to drive the VW XL1? :-P
I know of a vehicle that can go 15mph and gets infinite mpg.
+Jween Tech Oh yes, bycicle
well you still have to fuel yourself. how many calories will you burn using a bike per mile. so there is that factor.
do the math tell me what you get, im kind of interested
oh you can bike 1767 miles without stopping?
That's not infinite, its undefined. Miles divided by Gallons of gas, when Gallons of gas is equal to 0, is undefined.
Wow that ginger is hella intelligent... you can see it when he talks. He knows his shit.
i have a theory that there might be a weight which isn't the lightest weight of the vehicle possible that increases the efficiency by increasing the coasting duration thereby gaining more savings then is lost by accelerating the extra mass. Maybe i'm way off here but i see it as similar to driving in rolling hills country side where your storing energy uphill, where the engine operates at high efficiency then releasing it down hill on the coasting phase. providing of coarse the brakes are not applied. is there a point which isn't the lightest weight possible where efficiency increases due to the nature of the internal combustion engine?
No.
+Explora21 H Def not.
imagine one of these with a stirling engine powered from radiant heat coming from the street, that'd be pretty insane
Jimmy Puppo ok that wouldn’t work I’m sorry. We may as well just use solar panels on houses to power it which is a much better motor. Same energy origin.
yes, i can imagine its so slow id rather watch paint dry.
I want some guy in a zombie movie traveling the wasteland with his self distilled moonsshine in something like this.
Matthew Niedbala
In any other case than summer it wouldn’t work. But considering that summer roads can be hot enough to run feet and cook eggs, it at least has a grain of plausibility. During that month, that is.
Houston Texas!!!!
Its so technologically advanced he uses a rock as a parking brake
Why don't they use zipp deep section wheels
plz describe the engine used in this car i wnt to make a report
Google weed eater engine
1767 mpg... at 15 mph lol. I'd like to think somehow tech will advance such that fossil fuels will still be viable at legal road speeds with such insane mileage but there's no upside for the gas companies so I'm sure they'll stall this as long as they can just like they did with electric cars
+Matthew Wilson there's already been patents for cars that run on hydrogen and oxygen, both via a water tank and even one that supposedly could get them directly from the air. But of course none of that will ever come to market because of big oil
+Matthew Wilson I hope you realise this event is sponsored by Shell
Frido15 the same company that held back synthetic oil for decades and bought out patents and paid hush money until they were ready to enter the market? Another Shell fanboy eh
+Mathew Wilson Note the yellow sticker on the side of these vehicles.
Yep. Just lip service...
How can we get such high mileage out of a scooter or a small cc motorcycle? Best ive gotten is 70 mpg, 200-300 mpg is what I would like, even more would be better.
SweetLowFat Jesus i drive a pulsar 150 and I get about 45kmpl / 120mpg
Look At record vehicles. Build a fairing.
So hot that that chick knows what she's talking about with cars :D
Do I smell a TFL Car mash up?
those tires wont last 1767 miles lol
I weight about 220 pounds (100kg) . Without heavy breaking and skiding , I can do more than 2000km (1200mi) with same tires on my bicycle . But you are could never understand that .
Mladen Milić that only works if you're going 15-25mph. The vehicle in the video can go faster than 35mph and you need to understand that higherspeeds will wear out the tire faster than a human riding a bicycle. I'll give you a cookie for riding 1200mi kiddo.
I drive a bicycle - I do about 800 km every year and last time I changed tyres was about 3 years ago and these are still ok , but I have to point out that I rotated front with rear one last summer . This mega MPG numbers are achived on average speeds regulated by rules - 15 mph . Air drag gows with v*v*v (v^3) so by dubleing speed you have 2*2*2=8 times more drag . That means that they can do 1700mpg on same tyres on one gallon of fuel thereticly , but that would take 5 days of non-stop driving 15 mph .
yeah but you dont do all the 800km in one day. tires get hot after very long distances. just feel your tires whenever you go longer that 100km
I used to have Continental Gatorskins on my last bike, they lasted roughly 2000 miles... but thats why they're $40 each!
Keep in mind gas has 3/10ths more cals per gram than ethanol.
it just like a super car.... mid engine... rear wheel drive ..... lolzzzzzz
Wow.
Calm down folks. These things are an engineering exercise. It is so these aspiring engineers can play with aerodynamics, advanced engine controls and other ingenious devices and maybe learn something they can apply further down the road.
so SO SO SO!
I don't see the whole point in this...Yes they are very efficient but only when traveling around 15 miles per hour. That would take 117.8 hours to go 1767 miles.
beats walking
Recumbent Aero bikes can make a 25mph cyclist into a 40mph one. This could be a cool way of cheap travel n camping. Bit of solar power bit of gasoline and your legs combined getting you to 50mph at 500-800mpg. After 4hours you are tired. You rest 2 but ride on. Then another 2. You cover 400km a day and set up your tent.
sko buffs!
I think these have more consumer potential than people think. They arent going to replace cars neccesarily but a bridge between bicycles and cars for lazy people who want efficiency.
Nice and not extensive .. That much milage who cares about speed . local or break up your trip !!! Free traveling !!! Work on regular vehicles body to get high milage . drive slower and glide .. Their not even using vapor fuel . lol . where do I find parts of buy one ?? Parts is good .
Have you considered recirculating exhaust to recapture some of that unburned fuel? A chemist might be able to help you with a catalyst that when put on a mesh can recapture unburned fuel.
It probably have just enough power to run around the parking lot, can't take any hills I am sure.
well at least its lightweight so you can push it up the hill ;)
Why do they always use 4 strokes? Use a bourke engine.
bet! make it commercial
But it's is never been come with public use . Change design with 2 seater motor bike .
Why do those people start their sentences with "So" when responding to a question. It ticks me off when they do it every time, lol.
Like, it's better than them using the word "like" in front of everything. Like it's annoying to say "so" but, like it's not as bad as them like, saying other stuff.
So, actually and so.... must be part of the secret code.
It's equally annoying when people end them with so as well.
My mother says the same thing. I find myself doing it quite a bit. I guess it's just a bad habit of the younger generation. I've heard people doing it for years, though.
Stick a turbocharger on it lol
So we need these to be sponsored by Shell, but not 50 MPG SUVs?
must be scary as hell driving those things.
lets just say they wouldn't hold up well in a car accident. eep
I mean... if you get into an accident on a closed course that's around a parking lot for a competition where the goal is to go a minimum of 15 mph for the highest gas mileage... I'm imagining you'd have to be a shit driver or mental. Or both.
If it can reach 70mph and it can be registered it's on my shopping list
gg
And that is a goal I’d love to have. Look up Velomobiles, if you may. Add a motor to it and you essentially get something like this.
You say secrets revealed but nothing has been revealed no one ever says exactly how the retrieving the incredible mileage as far as the engine itself is concerned
I’ll tell you what this video really means. The people of the US could save staggering amounts of capital and resources if they radically reduced the weight, speed, and windage of private vehicles on public roads. That’s a simple fact. And it can’t be done right now because big, fast vehicles own the road. The public policies that make it that way are strictly determined not by the people but by private profit interests, chiefly the financial sector but also advertising, construction, insurance, and of course the car industry, all of whom profit hugely off of forcing everyone into a wasteful and expensive mode of transit with absolutely no future. To avoid dying on this hill, the American people must form a government that decouples public policy from private capital interests.
I have done this year over 5000 miles per 0 gallons! That weird machine in called bicycle!
Only Chuck Norris is capable of this miracle
+Chuck Norris Food production is way more resource intensive than petrol production. Just sayin.
That's great, if you want to travel at 18 mph everywhere you go
+paul rogers A more practical challenge would be nice. 4 door /w cargo space targeted @ ~73 mph. Sure they wouldn't do thousands of mpg but maybe a couple hundred.
Hell, even if they just had them go at highway speed, id buy one of those.
if you look at a city car's average speed you'll find its around that figure
I'd actually love to see travel like this, but combined with cycling. So. A 3wheel recumbent, bit of solar too. And perhaps going quite a bit faster for a couple hours per day, when you are tired and the sun goes down you go more for fuel. I imagine a tiny electric motor could help a bit still. Maybe getting 800mpg and 25-40mph
VW tried their best on the XL1, seems like a practical car would do about 100 mpg. But then again there has been some time since the XL1. Maybe we can push that a lot further.
"You can almost drive across the country" if it was flat
Solar and electric
$30.000 for that thing holy shit and it's only got a small 4stroke motor probably cost couple hundred dollars and push bike wheels one expensive tub
Ethanol is also 106 octane race fuel! Not to mention less than 10% the emissions of gas clean as hec. Good choice.
Jay Santos
could be good point as far as food I don't know. as far as messing up motor how is that? its race fuel prevents knock good for motor.
boostercontrol100 ethanol vapor turns back into water as it cools inside the motor. this causes oxidation that blocks passages and constrict fuel flow. ethanol also usually needs about 15% gasoline to make it burn properly.
charles bishop I been running 4 and half gallons e85 in my mazdaspeed 3 for like 6 years 100,000 miles on stock injectors. Everything still peach and making over 400hp to the wheels stock motor. There alot rumors out there I know its a great race fuel with only like 8% the emissions of gasoline.
I don't know about any rumors but a quick Google search can turn up a few facts.
On the other hand I have seen the runners on a S10 Blazer intake manifold that were 30 - 50% blocked by aluminum oxidation. I don't know where the oxidation came from but I was told that it was from the ethanol in the gasoline we have to run in Colorado during the winter. They're only a couple of gas stations in the state that sell non ethanol gas during the summer as well.
Also, I'm not sure, but I don't think the injectors have aluminum parts.
Do you have a turbo on your mazda? Big big fan of small motor big Power.
Stop using this music music. Whenever I watch this with my parents they think im watching something else
heck I would be more happy with a 500MPG in more of a bicycle body :)
Non aerodynamic bodies are a real... drag.
I would not drive this in fear of lifted pickup trucks driving over me.
could def use some work on the aerodynamics lol
a three-wheeled vehicle is considered a motorcycle in Colorado.
can i drive it on the road long as i stay under 20 ? lol
I have a friend who build similar cars like these. The difference with his is that they run highway speeds and more. Plus his is completely street legal. This is a link to his Facebook page: facebook.com/alienvehicles/ go check him out.
super cool craftsmanship.
Tell them to stance it lol
you guys are driving around a parking lot, not really going anywhere necessarily, to show the everyone how little amount of gasoline you guys use? Does anyone else get this?
damn i was expecting a car powered by hydrogen
Why? ethanol is readily available (corn or soy oil) and easy to obtain. Hydrogen is not. Hydrogen has to be manufactured from another source (like oil). Not convenient at all
.
Sounds like someone snuck in some porn music at the very beginning from 0 Minute 23 Seconds to 0 Minute 45 Seconds.
their should be whole roads made for smaller slower less regulated cars
Or the right lane...
expensive n useless for a car... unless they consider to put cargo area n comfortable average seats u know i prob dig it. taking it on for cruise, the mpg is quite good concept, but then again crash collision would b another thing
nightmare oil companies
Hear me out: drive these but in dedicated pathways ONLY by AI in big cities. The pathways are light enough to be built above ground and even connect to buildings. Dedicated structures and AI only makes it a consistent environment AI can operate in properly, with user override for emergencies. Musk's underground tunnels are only useful for military use, not current transportation. With these they become far more viable.
isn't that just a train
Trams
Interesting technology but highly impractical unfortunately for the consumer with how things are. Great vid.
We could get better mileage in our cars but they ain’t gonna do that
I wouldn't call that a car...
The rules are boring and not leading to much technical improvement, it would be much better if the engine had to be on most of the time.
just use a horse . infinite mpg
Our hole auto industry have to change ! This includes the highway industry . In order we can have cars like this on the road . 18 mph is not going to cut it . We need to be at 50 mph to make a difference in time and distance . The auto indusrty with a good help of our crooked government that is bought off by the oil giants . If we only made the auto even lighter and not heavier in the last 40 years then we may have cars running with less than 400 cc engines and getting 80 MPG . Not the other way around when a subcompact car weights in at over 4,000 pounds that is just stupid . A small SUV is close to 6000 pounds . That is heavier than a 1959 Cadillac . We are traveling at speeds above 70 mph . If the speed limit was reduced to a modest 45 there would not be any deaths . Heck semi trucks is running over 80 down the interstate . At those speeds there is no chance of survival . I dont care how strong and heavy a car is .
They must get closterphobic
I have to wonder what is the point of the drivers wearing racing style helmets? Come on, they're going 15-18 mph... in a parking lot... in an enclosed trike with 2 front wheels (extremely stable). The helmet seems like pointless additional weight that's probably not that comfortable, either. Oh yeah, they probably see these as more like gas powered bicycles, and bicycles MUST be dangerous, right??
I wonder if that one carbon fiber vehicle would do any better with 20" front wheels (typical on recumbent trikes) instead of the usual 700c bicycle wheels up front.
+Connor Toale yeah but in a vehicle like that I don't really see how that could happen. It's not like they can fall off, or even fall out.
+Patrick94GSR Remember that if they where to crash. Let's say they have a worst case scenario with a broken wheel and the body starts to roll over. The shell isn't that sturdy so it will easily collapse and break in.
It's like the old ww1 helmets. They didn't protect the direct damage, but made sure the damage was way less! 😃
+Patrick94GSR i can run faster than 18 mph so should i run with a racing helmet in case i fall?
I wouldn't buy a smart car if it was only $5,000 why would I ever want this? Do appreciate the technological path they are taking that's incredible, but unless it meets the needs and desires of all consumers this will go no where.
if it meets only 1 percent of a billion people that's still 10 million in sales and a large impact on the emissions
you are missing the point about these vehicles.
How am I missing the point? I definitely acknowledged the fact I appreciate the path this is creating and I do appreciate these young adults for pitching this idea and going forward with it. I just don't see how this type of mobility at it's stage will be practical. There's still a lot of issues needed to be implemented to be a full fledged capable automobile for the masses.
But you're still missing the point. It's an engineering challenge that breeds ingenuity, not a plan for a real production car. Of course nobody is going across the country at 18mph in a tricycle.
If it wasn't for things not being mass produced being u viable this would be viable as heck. Just as recumbent bikes with fairings. Gimme a solar cell, small e motor too, gimme that thing and my legs and I can go 50mph for 4h a day with it at 500mpg. Cool. Just too expensive because unviable. I mean okay carbon is pricey but plastic would kinda work too
LOL they're wearing helmets for this......... please
Make a law where people have to drive smaller car and gas saver simple
They should make it minimum 60km/h driving to get a more sensible practical vehicle.
That's a bicycle. No technological innovation there
