At the end you proved why you are the best!! I see people on livestream all time saying “just do to 50%” and extrapolate or stuff like that. This test would have been totally inaccurate if u did that way. Thank u for your dedication.
@@GregHassler So you wanted to watch him get towed from the side of the road?
@@PhilKulak Yes! And send DB the bill if it was lying about the range/capacity.
The other option is to abort as he did, but then drive around the charging station until it's down to maybe 1% so he can make it 200m to the charger.
Maybe he can work with someone to have a portable charger available, put a 50kWh pack in a trailer or something with a charger?
We really need to start seeing these kinds of rescue vehicles, maybe a business opportunity for someone?
Strip out a model X and put another battery and charger in the back. Or maybe an S "truckla" type thing?
@@GregHassler Bjorn pushed it to 6% on his trip to bergen. And later filled it up again. It accepted 58kwh. Look at the lifestream video, its all recorded.
Agreed. :-)
It is wrong to be so rude just because you disagree
Bjorn you are getting to the point where you are "the" world authority on EV testing. Keep up the exemplary work. Much appreciated!
EQC range drops quicker than fuel range in euro truck simulator.
It might seem more efficient because you were getting good numbers but maybe most press people just do 50-100km so they set up this car to show good range for the first 50-60% battery, when in reality it may have been using 30-40% more energy.
So cheat software for a German company?:o Why would you even think that was a possibility
Thought about the same, I believe the consumption is also not accurate. Maybe should have maybe drive it near empty near a charger?
this is actually a simptom of a bad battery, it happens with cellphones too, when the battery is bad, the last percentages drop crazy fast
I would think ... it’s just charged high stage of charge between 80-100% the hole time, and the bms have that’s why a big offset ... or you could be right and they cheating =D
The battery gauge on the EQC reminds me of the fuel gauge I've had on some past ICE vehicles.

This is unacceptable battery management and information from Mercedes.
BMS-gate
BMS = battery miscalculation system
@@karenrobertsdottir4101 Think this is more about the type of batteries they used. The rated capacity could be correct, but the consistently draw is not. at full charge till 1/2, the batteries output is pretty consistant, but once it hit a certain point, battery drain to keep up power demand multiplied. It's one reason why tesla went with cylinder type of batteries, they get consistent draw no matter what range. So nothing wrong with the BMS, the batteries just sucks.
Gordon Chaffin - I’ll cut Mercedes some slack here. BMS is surprisingly difficult to get right, and it becomes more difficult as you add more cells. Lithium batteries don’t give a whole lot of feedback on their condition (via voltage) until you get to the top or bottom of the charge. When you’re in the middle of the charge, the BMS is kinda going by dead reckoning, which can accumulate errors. That’s why Tesla owners recommend doing a full 0-100% charge cycle to their packs when the range gets too out of whack. That allows the BMS to “discover” the top and bottom limits of each cell again.
In which case it's would also be a software thing as well as an "real" capacity thing. They need to adjust the %/range algorithm to compensate for the battery behavior so that the SoC is linear (based on actual driving) and the range predicted is accurate.
I always wondered what happened to those VW cheat software engineers - maybe they now work for Mercedes 😉
Shot in the back of the head and corpses dropped in the Baltic sea. They knew too much.
Maybe it's like my phone where I can watch 3h of youtube with 1% of battery 😀
Those engineers are probably still working for Vw. A court in Düsseldorf just recently found out that the updated diesel engines are still having a defeat device. Exhaust gas treatment on the updated engines only works between 10 and 32 degrees celcius...
Stefan Saxer . Interesting- and unrelated - very cool name !
maybe 270wh/km is in reality 370hw/km, can't trust any numbers on display!!
That nonlinear decrease in capacity could be the result of a bad battery cell. The Chevy Bolt EVs that had faulty battery cells from factory behaved in a very similar way. Hopefully, Mercedes can clean up their battery manufacturing process in the same way GM/LG did.
Right. When using pouch or prismatic cells, because there are far fewer of them than with cylindrical cells, the failure of a single cell can have a large performance impact. That may be what we are seeing here.
@@npbetts1 Yes, I don't know the total number of cells in the EQC, but the Bolt EV only has 288 cells, so a failure in any cell will make the bottom ~20% of the battery completely unreliable.
@@newscoulomb3705 I can't wait to hear what Mercedes has to say about what the problem is.
Charge percentage is an estimate based on current battery voltage, which doesn't drop very linearly. Could very well be a honest mistake... check out this image for an idea photos5.appleinsider.com/gallery/24198-31518-Li-ion-Discharge-Voltage-Curve-Typical-l.jpg

You should try driving the eqc around the ionity charger for the last 75kms till the car goes to turtle mode.
Does it have a turtle mode?
@@sokolum Something else that would be good to test/discover. :)
Hahahahahs... 😂 😂 😂
@@sokolum has a turtle on the dashboard inside the speedometer display / you can see it when he is charging it
Somewhere in California, Elon is having a laugh.
They rejected Tesla batteries and drive train. So Mercedes needs to learn that was foolish and will cost them money.
@M Hadi You are right every new BEV is welcomed even quality seems good, technology not up to date and look is ugly :D
Hope not, he would spend his days only laughing judging by the competition...
He sure has no reason to laugh. Tesla is only superior in range. The rest of the cars is very poor in quality. Barely any Body part without problems and poorly assembled.
Because early Teslas never had any problems, right ? And current Teslas are perfect and bug free , right ?
I'm pretty sure, this battery pack is not properly balanced, or some group of serial arrays cells are different capacity than others.
I build, my own solar battery packages, following jehus garcia style (tesla style), and normally it happens when for example group of cells 7 is 0,15V below the others groups voltaje. When you charge your battery, all the groups are 4,2V but this group 7 is 4,08V, then when you discharge your pack, this group will reach bottom level when all the others groups are still with charge, then the BMS needs to shutdown the whole package, to save the live of the group 7, but then you still have a lot of energy in the others groups that can't be used to protect group 7 from overdischarge.
You can fix this, chargagin at low speed the battery, giving days to the BMS to balance all the cells, it's not enought with a 0-100% charge, we are talking more about, charge 10 times the battery from 30%-90% at 3kw, it will take several hours, but will allow the BMS to slow burn energy in the good groups of cells, while still charging the unbalanced group 7.
This stuff is messi to explain, I hope this explanation helps someone to improve his battery management.
It might be an idea for the manufacturer to do this kind of "battery pre-conditioning" when the pack is manufactured. It would/could also act as a burn-in test to identify any dodgy cells/packs so they don't go into production. One would presume individual celss should be/are tested as well before they get put in a pack too.
Maybe Tesla does this?
Carlos Portillo Sanchez But But But this is a Mercedes! Like the time I drove the first I3 BMW at CES rollout. I looked my BMW rep in the eyes and said “ This is a BMW? “
@@eubikedude I think they can't, it's something that the BMS do every day, rebalance the cells, but this BMS for example on solar systems, burn only 1Amp, if you are charging at 200Amps, the BMS doesn't have time to rebalance the cells. Becuiase the higesth cell is charging at 200A-1A=199A, while the lowest is charging 200A, difference is to small to balance a prrety unbalanced pack. This is why is recommended slow charging, not only because the life of the cells, too to give more rest time to the bms to improve the cells balance.
@@daviddrake7003 I don't understand you... :-)
Note the same "gear" stalk at Tesla Model S and X; for those who don't know Tesla and Mercedes have a parts sharing agreement. So many of the Tesla Model S and X buttons/switches are from Mercedes. Nice to see Mercedes use the same parts still !
Tesla clearly wants to get rid of this, as they are reducing the number of switches :')
That was all going so well can’t wait to find out what went wrong 😮
Mercedes caught with their pants down... They were really asking for it letting you drive, Bjørn!
The legacy car companies think it's easy to make an EV. They all have a lot to learn.
I imagine the executives at MBZ are now saying” Shiiiiiiit!” More than Bjørn! 😱😂😂🤷🏼♂️
"Bjørn Nyland ist not like Fully Charged??! Verdammt!"
npbetts1 - The legacy manufacturers are still using pouch cells, which are more expensive than the Tesla style commodity sizes (18650 or 2170). Only Tesla has figured out how to control and balance thousands of cells, and they only really perfected that with the Model 3. The S & X still have problems with their packs acting up, although they’re much better than before. But the legacy automakers have trouble managing a 1/10 of the cells as a Model 3.
@@nilreb No proof of course, but I believe the reason MB dropped their partnership with Tesla was because they thought they could easily do it themselves if they ever needed to. Now that they do need to, they are finding it much more difficult than they thought. Imagine the product MB could have today if their interior design, chassis engineering, and manufacturing expertise were combined with Tesla's power train and software capabilities. Arrogance on MB's part is to blame.
Sounds like a buggy BMS - perhaps an early gen car problem?
in a Mercedes? u kidding?
Trades46 - Yeah, early bugs are pretty typical. The early Bolt’s also had BMS problems, and that system was built by Koreans (who REALLY know their electronics, unlike the Germans).
@@mattaut88 for ANY car you never buy first year, even for brands like Toyota with good reliability.
@Onkar Sawant Just like how Tesla "cheated" the range numbers by pushing the battery beyond its limit & degrading the range right?
You're making conjectures.
@@Trades46 conspiracy theory. Elon musk lies to us.
There seems to be something wrong with your unit, Björn!
We’re working on it and will get in touch with you.
Thanks for bringing this issue up and for just another amazing and unbiased video. Love what you’re doing,

Head of Digital Transformation @ Daimler
+Sascha Pallenberg Awesome :)
The EQC instrument cluster is so cluttered and busy it drives me nuts. Tesla really hit it spot on with it's minimalist interface
Bjorn, don't you think that the displayed consumption could have been wrong too?
At 6% charge and filling it up to 100% it accepted 58kwh of charge.
Andy And that was not tested in the factory? What about quality control? This is not some shitleister brand. You expect better from Mercedes!
Reinout Schotman u don’t know when it failed. But not like Tesla he just had to go to a service station and they fixed the car. No 5 months waiting time, panel gaps, quality issues.... etc..... I really don’t get why people hate on German brands so much.
Reinout Schotman I agree wholeheartedly. Shall we say Nekulturny??
That confirms for me that the other youtube test attempts were cancelled with no further explanations or awkward excuses or simply ignored that problem without any range or efficiency results. This car stinks like shit as those testers are. Its a Fakecedes EQC. Thanks Björn, for your honesty!
Quite efficient at 90...if those numbers are valid 🤔 But 271Wh/km at 120?! That’s a *lot* compared to my MX, which performs those kind of numbers on snowy winter roads (E4) with 20” Hakka 😲 Not sure what temp the battery had when you started the 120 test?
Maybe the cells are misbalanced. A nice long, slow charge might help.
Otherwise I will go with bad battery cell causing the issue.
@@DavideBonetti actually balancing is needed with a full slow charge on almost all cars once a month. Otherwise the predicted range and battery percent can be completely wrong. To balance the batteries a full charge on the in car charger is needed. Multiple partial charges, or charges on rapid DC chargers means the cells will become unbalanced.
For most people this isn't an issue as they generally charge to full on AC most nights at home, but for those who only rapid charge it becomes an issue. Bjorn himself has demonstrated this issue on Optimus Prime.
For US viewers, that's 161 highway miles before mileage left starts falling rapidly, bailing at 167 miles to recharge. Range spec is 250 miles and dash usage indicates high efficiency. This is an excellent test methodology! Thanks Bjorn!
I really like the EQC, looks like it is less thirsty than the iPace or eTron. Also BMW i3 also shows temperature of the tires.
I like the EQC very much. i hope this was only a problem with this special car.
Nosy what you can find out. Thanks Björn.
how bad is the non Tesla charging even were a Tesla has got to line up they have min 6-8 chargers, theirs no way id buy a non Tesla at the moment the infrastructure just isn't there.
I would buy a non Tesla EV, because I have electricity at home. For super long trips, I'll rent a fossil.
Mercedes EQC is the Biggest Mercedes failure...
The worst, most expensive electric car...
Another great info-video Björn!
You're #1!
Congrats ! I personally appreciate your dedication in testing (e)cars. I'm subscriber by quite a while and these tests never let me down. However this Merc let me down a bit because I have a very positive point of view regarding this brand. I just hope they fix whatever it is wrong with BMS and this vehicle will rise up to the brand standard "The best or nothing" .
Cheers and again congrats.
Any reaction yet from Mercedes? I just hope that it is an easy fix. The car deserves it in my eyes. Great video Björn.
Tesla is still the EV champion in Range, Performance and Efficiency. Still waiting for a Tesla Killer.
Tesla is working on few... oh...
Porsche might best them on performance. Not on range nor efficiency.
Great analysis Bjorn! 100% battery to 0 test exposes a big issue (or cheating)! Looking forward to hearing what Merc tell you!
I bet Merc and Porsche drivers will love queueing up for chargers lol
How can you even trust any number displayed on there?

Your giant hand makes the MB touch screen look so tiny.
Nice Video. But you bailed out very early. The old Björn had drove it to zero. ;-) Perhaps, if you had driven the car to 5% in circles around the charger, than at the end it had stabilized? A time ago in my C-Zero I arrived at my garage with zero range, and no bars on the Battery-Display. So I started to drive circles around the garage. I drove half an hour, with heater running before powerlimit kicks in, and heater shuts off. So I parked the car, and let it charge overnight at 2,2 KW Power. After that, the "BMS-Range" increased by 15 kilometers and displayed more accurate. In the manual of the soul, they even tell you to discharge the car below 5% from time to time to recalibrate the system. Perhaps thats all what is needed to heal the EQC.
+Thomas Rossen Driving to 0 % with a defective battery is a BAD IDEA!
So again, nothing much to wait from these historic manufacturers.
Sure fit and finish is better than Tesla, but the huge price asked for that poor range is unacceptable.
That's like they are telling us : "see, EVs are shit, continue to buy our fossil cars".
pxidr its like saying Tesla has good range but unacceptbale Build Quality.
Noise it just not volume, it's also frequency spectrum. You should up your game and provide spectrum analysis of the noise :D
On my German EVs I find the eco modes quite acceptable on the highway. Its works particularly well with ACC active. ACC sort of removes some of the power limitations of eco.
I'm rather worried about the crowded charging station. What will be the future when even more EV owners exist? And I assume Norway has a rather good network/amount of chargers compared to other European countries.
+colla 555 No queue at Nebbenes supercharger. LOL
@@larsradtke4097 how does it look like? It's basically a parking garage / car park with charging stations? I mean I don't think they have so much space, so they must build vertically
Valid concern, the charging times are dropping though, that should help.

Anthony Woodruffe Supercharging is often too fast!! Shiiiiiieeaaat..
Fun physics fact. Because the boundary layer on your car doesn’t move, weather it’s clean or dirty, there’s no measureable difference in drag. That’s why doesn’t doesn’t blow off when you drive at 120kph....
My dad bought eqc and return to the seller because of very low range, high consumption of the climate. Also 1886 version so it change with a plugin glc.
I prefer all the way the eqc is better than plugin Diesel, also the interior is better
Navigation screen could be a little bigger.
It has two big screens. Surely you can have it larger, if you want.
Efficient? Only if you believe their first 1/3 numbers.
Use the full charge info and it is ho-hum.
Is it efficiency really that good? Compare to way bigger cars like Model X and less efficient Audi e-tron maybe. Compare to inefficiency king I-PACE maybe too. But EQC is actually as big as Tesla Model Y. Its direct competitor. Model Y LR AWD with 75 kWh battery has 505 km WLTP range and consumption 14,75 kWh/100 km. And EQC has 417 km WLTP range with 85 kWh-ish battery and consumption 20,38 kWh/100 km? EQC will be probably about 38% less efficient than Model Y. And that's a lot. Not to mention for twice as much money. EQC should be more close to Model 3 not similar to 2 class bigger Model X. I think no miracle is happening here actually.
model x 75d is 220wh/km in typical motorwayt driving. and this is 270?
@@GregHassler What "doesn't exist" means? Not yet on the market? But EQC neither. These are just preorders. Will be in the end of next year. Same as Model Y. And this is just a journalist car. Lots of parameters can be changed. For example BMS apparently. 😁 Model Y was tested. WLTP isn't some agency it's a procedure. You don't have to send a car somewhere for testing. Every automaker can do the test by himself and anytime.
And you right this isn't about Tesla. But about EQC neither. It's about impresive efficiency. But EQC don't have impresive efficiency. If you don't want to compare with others. 😉
Mercedes couldn't resist to implement big grille and big hood and big wheels and big everything. But then aerodynamics and weight goes to hell and consumption goes up. But he had no choice actually. He wanted to make it easy. He didn't want to bother making EV from the ground up. He wanted to use it inefficient combustion GLC instead.
@@GregHassler thats from tesla under typical range hardcoded in car
@@GregHassler Compare to things that exist? There's just one car in the world in that segment. I-PACE. And that's apparently total loser. Every car compare to E-PACE is efficiency king. And comparing to bigger cars is bullshit. Than you can compare with smaller Kia e-NIro too. Same "accuracy".
Reminds me on my first electric scooter tests in 2006. They had only a Volt-meter to indicate battery status.
To determine range with some experience, go to full power, watch the reaction on the volt meter......
"...the shit hits the fan..."? No! It's "...the shiiiiiiiiiiiiit hits the fan..." LOL!
Meh... it had such a nice potential at the start of the video, until that major drop in SoC, but the real surprise was the rapid loss during the hillclimb. Either the display is totally miscalibrated or the BMS sucks, Daimler REALLY needs to fix this!
Even if the merc didnt hava a bad battery, the GPS sucks compared to a Tesla. Bjorn had to know exactly where the charge stations are located.
Come on guys, the EQC is a nice car, BMS notwithstanding...at least give them a chance to fix it...it is a pre-production car after all. I think it will end up joining the e-Tron with an EPA rated range of 204...
he said he'll ask for another car
This is *not* a pre-production car. It's a production car with a defect in one of the modules.
@@bjornnyland Oops you are right. I stand corrected. Don't know why I got that impression (should have done some fact checking). As you say in your next video...I am not very smart!
So it seems it is not so easy to create a good BMS software. Maybe they should ask Tesla for help. "The best or nothing"? ;-)
That's pretty much how gas gauges work so maybe they decided to mimic the design?

+Rob Burgess no
@@bjornnyland Hello, nice test. Would you share if there are some answer from Mercedes? About battery and consumption: how many Kwh could be charged from 15% to 100% and how many km was possible to reach with this. Thanks. Have nice day
@@bjornnyland thank you for the answer in your new video 😃. Tray to get the "AMG" version for your next Range test. The front looks greater. Regarding drive modes: not sure if D - - is the best 🤔 cause to regen has more losses then to let's roll ??? I'm not sure. I wold take Navi and D Auto. Viele Grüße 😀
During the EQC test, neither the battery was driven to near zero or below nor was it charged from near 0 to 100% in order to determine the exact capacity. It may also be possible to have a residual range of perhaps 30 km below SOC 0. If the battery is really faulty you should assume that clear service or alarm messages are displayed. If one assumes a faulty BMS, the indicated consumption is not credible. Nobody knows until someone dares a full test.
On the other hand, assuming a higher consumption like the I-Pace, the not linear puzzle is quickly solved.
Thus, it is the best car to drive at 90 km/h a maximum of 250 km,
and when compared with the test results of fossil cars in the German newspaper Auto Bild, the EQC is not even very quiet.
I wish Bjorn had recorded the recharge KW to see if it is a BMS SoC miscalculation OR a Consumption miscalculation
the CAR APPEARS to have awesome efficiency BUT maybe is not as good as programed / displayed and the BMS does NOT know SOC till the lower 1/3
and the range then drops down
+jason riddell kW or kWh?
Just crunched some numbers.
Using e-trons efficiency you should get you around 330-340 km range.
Why should you get better range in the EQC than for an e-tron ?
If the consumption gauge is wrong it will make wrong GOM readings.
Percentage is probably calculated mostly by consumption on the flat part of the discharge curve (until around 25-30% left) and then regulated after (or correlated to) cell voltage when the discharge curve starts dropping more.
This would give that behavior - also more pronounced with the low loads like the 90 km/h test.
You need a calibrated and well mapped (temperature) resistor to measure current precise.
If that is screwed the kWh count is screwed and the BMS uses shitty data to do the calculations.
4 years ago. If you have a chance to see my question. Did MB fix that issue ? Or it is still a nice car with useless BMS ?
i think, mercedes didnt have a 80kwh battery ready for the early press-car and put a smaller one in. Because most of the press-guys only test for 200km and write theyr article. Its possible, that mercedes just cheated the software to simulate a bigger battery for better press-articles.
Internals of cars are starting to look a lot like Teslas from 2012 (huge screens). Only took them 7 years to catch up.
I like the Benz screens
Lol spotted the fanboy ;). Tesla has nothing in Mercedes and the other German makes when it comes to quality and luxury inside
@@DarkChasmGamers I was referring to less physical tachometers and more screens not interior build quality. But sure call me a fanboy for pointing out how Tesla lead the way for adding large screens to their vehicles.
In fact this screens (or pre versions of it, same design) were first featured in the new S-Class.
Production start Tesla Model S: 07/2012
Production start S-class version 222: 06/2013
So it´s just one year apart and the design of the new s-class design took about 5 years.
Also this s-class had an autopilot mode and the cool adaptive light, emergency features, ...)
What did Mercedes say when you contacted them? Did they lend you another EQC to finalize the tests?
The Bmw 5 series can change lanes but you have to put the blinker back when the car is in the lane or it changes another lane
Yeah, I wouldn't trust any number from BMS... Not even the instant power usage figures.
Reminds me of SD cards sold for a given capacity, and you could only write on 50% 😒

Tesla Killer hahaha
Noise killer. You need to drive slow like a grandma and carefully otherwise your range is lost.
@@mirkonaumann1417 nothing what a good stereo wouldn't fix 😉
I would guess guess a few cells went bad but the BMS either hasn't or doesn't re-learn the reduced capacity (due to having a top-buffer, so no need to?) and therefore assumes it still has full capacity and hence gives a false range. The rapid deterioration of the state of charge (%) is showing the true state of the battery (under load).
On the plus side if this was an ICE car you could assume the rapidly diminishing fuel capacity was a fuel leak with it possibly spraying over a hot engine and your car might catch fire, but then you wouldn't know until it happened :-p
Great efficiency. Hope the bugs get sorted.
No bugs. Those are features :P
Great what? How can you trust any number in that car
percentgate
Why does Daimler not design an EV platform that would allow substantially better packaging than reusing an ICE platform that is designed for an inline-6? Our E400 wagon‘s has the worst infotainment compared to the our Teslas.
A failure in a tested and approved module in a production car is a serious problem. It will not fail with no reason. It could be a production or a design failure.
Interesting. Now, thanks to germania, we not only have dieselgate but evgate.
Are you sure that you can trust the consumption displayed in the car. When the BMS is messed up I bet that the consumption isn't accurate, too. Any thoughts on this?
should be accurate because for these numbers cars are measuring what is leaving the battery, not estimating it from state of charge
Mercedes will start in the new Formula-E season on 22th of September. they will present the drivers on Sept. 11
Like your Vlogs. This one reveals you to can suffer from range anxiety as well. It may be software but the end result is the same. Uncertainty forcing a change of plan. Then to put the icing on the cake, a queue to charge up. So unfortunately, a very poor day for the evolution of mass EV adoption in the foreseeable future.
Still primitive battery performance, comfortable but dated.
Could be broken battery not BMS?
@@danfrederiksen1607 "could be"??? You surely meant "must to be", right?
Could be piece of shit engineering too. Still can't match 2012 Tesla battery tech apparently.

@@danfrederiksen1607 this is actually a simptom of a bad battery, it happens with cellphones too, when the battery is bad, the last percentages drop crazy fast
A press car is always the best of the rest, so it will shine. It didn’t and that is strange to me.
ETron will change lane also with indicators
Wow! Uncool Mercedes! At 11,000 miles on a Chevrolet Bolt EV that has never happened.
It could be bad battery cells or buggy BMS software.
If Mercedes updates the BMS software and the issue is still there then it's a bad batch of battery cells.
Still, nice looking EV car though.
You guys thought of, that the consumption shown is wrong as well?? I mean Bjørns calculation are only based on the consumption. I don't think it's so efficient, 400km of NEFZ is what they advertise! I mean this can't be true, 400km real range, never
I will test it on Saturday. Try to repeat the test and look what the result will be...
Press cars are always the best cars possible. So, the issue is clearly a VERY old one: batteries discharge (their voltage drops) much faster after 50%. Quality is batteries= their ability to maintain nominal voltage AFTER being discharged beyond 50%. Unfortunately it looks like Mercedes has chosen the wrong batteries.

Now Björn has flashbacks to the 2000km Trip with the eNV200.
You should keep in mind before saying that the manufacturer produced fake range on this car but anyways this is the first Mercedes fully electric car, so of course there will be mistakes but I bet Mercedes will learn from their own mistakes
maybe this is the way some EV manufzcturers do in the calibration of their charge meter, to be very optimistic in the higher charge state, as most auto journalists would not have the opportunity to conduct a full test but to extrapolate from a short drive result, and thus gives the car a seemingly impressive EV range.
Still, germans dealing with issues Tesla solved 7 years ago.
LUL
Yet tesla still can't make a car with properly aligned body panels lmao
Dimitar Iliyanov yes but that’s not a problem. As it is very unlikely to be stuck beside the road because of Battery failures you don’t have much time to look at the gaps with a Tesla ...
Do not use mobile phone while driving!! but look at that dash display, you can imagine how many drivers are going to be totally phased with that lot in front of them.
Wow, not good Mercedes!
Mb also cheated on range of plugin hybdird C350e. Goes about half of displayed range which is about half of advertised range.
I'm unsure how you can state that the EQC is as efficient as the Model X, when in the same breath you say the "Model X is way bigger". You then conclude that there is something wrong with the EQC's range. From this test, it seems like the EQC is either struggling to reach it's promoted range, or that there is something wrong with Mercedes trip calculation methodology; I do think that Mercedes really needs to pay attention to this detail.as it could leave people stranded. It didn't even seem like the hill you climbed was that large.
I Googled the weight of each vehicle and the Tesla Model X comes in at 5,185 to 5,531 lbs and the EQC comes in at 5,346 lbs. Food for thought... cheers all.

270Wh/km not bad? Just drove to Spain and back (3300km) in our MX at motorway limit speeds and averaged 230Wh/km. That was with 5 people and luggage.
I think he's just trying to be positive.
"EQC 400 4MATIC: consumption is kWt/100 km (mixed driving): 25,0-22,3. Range: 417 km WLTP... " Your test shows 182 Wh/km, thats not bad, but the BMS/GOM seems wierd..
I think it works as intended. Like in (all) fossil cars (I’ve driven) I would expect the fuel gauge of an electric car to drain faster in the last quarter and leave me with a reserve of 50 km, while indicating an empty tank.
I did not drive fossil cars too long so i did not notice that wired behavior before.
My notebook, Smartphone battery does not go faster down under 40% its (almost) linear as in my zoe and now in my model 3. Makes much more sense for me. :-D
We‘ll see. I’m sure he‘ll get a statement from Daimler.
MrTechfreak95 but is it really hardcore linear for real? So if you have 0% then it really stops driving? They don’t have any juice hidden, so that you can drive to the next charger?
@@Grzeroli1 it May have some Buffer or not. You can't really count on it. And when you have low charge don't output too much power. That makes the voltage drop. And if one cell has a low voltage the car may shut down earlier.
So I would consider 0% as 0. So you are on the save side.
@@Grzeroli1 At least the Model 3 has a few KM "after 0%" buffer as far as I know (there are actually a few videos testing it).
Another German disappointment with high quality but funny range. If BMW doesn't do better than its German rivals then I give up. At least they know how to make beautiful concepts with amazing fake specs.
Very nice quality on this video now :) looks like the video camera helped some extra
Charger queue is what I fear...
I live in Italy with a SR Model 3
If queues start to form i'll have to call Tesla to get a long range battery fitted
Should i get the gle hybrid or thid eqc ?? Family with 2 kids planning some trips to denmark from stockholm and at least one trip to Greece
Have you considered your own weight Bjørn when you weigh the cars?
The more EV's the better. I also read the Mercedes owns the factory where the batteries are made so that is yet another step in the right direction.
the more chargers the better. this shows again how great Supercharger Network is.
it tells you that you have to put your hands back on because it doesnt want you to fall asleep or something
You should use the same technic as your fossil testing colleagues -> measure the amount of energy used to refill the battery.
I would'nt trust the onboard consumption values, they don't add up, your test shows that well.
You allready are one of the most dedicated EV testers out there, stay ahead :)
That method is incorrect because of charging losses.
@@bjornnyland The charging losses should abolutely be considered. An exagurated example: If a 100kWh battery is good for 500km but takes 200kWh to charge fully, wouldn't you aggre that it took 400Wh/km?
