The range is Chinese CLTC range, which is a more generous rating than the US range ratings.It's an impressive range number, but don't try to compare it directly to range numbers for other EVs.
The current gen SU7 is available with an 830km CLTC range. If you drive one on real roads, you will not get 830km of range. :)

You don't get real mileage out of the declared Tesla ones either.by epolanski

The Tesla would have higher CLTC rated mileage too.My point is that you can’t compare ratings done to different standards.
Chinese CLTC exaggerates real world range a lot more than any other major measure.

How fast are you driving to get that kind of drop? That's a lot worse than what I experience. I find I get the EPA range driving 55 in the summer.by bryanlarsen

“That kind of drop” makes it sound like they’re doing something wrong. The EPA test is done at 55, so it makes sense that you get the same number under the same conditions of the test. And since energy usage is exponential vs speed, anything faster will show fast. If they live in hilly and curvy, add that to the math and you’ll find that it’s more likely that you’re the odd ball and will be asked “how slow are you driving to get that kind of mileage” instead.Don’t know where you live but it’s rare for traffic to move at 55 in many places. Either in city 25-45 or 65+ highway.
It is totally legal and fine to drive the EPA 55mph in places where traffic normally moves at 70, but must also recognize that when semis have to go around those vehicles, they cause ripples through traffic every time and increase risk of collisions for everyone.

Doesn't energy usage vs speed scale as O(n^2), not O(e^n)?

I don't get a 40% drop in range even when it's -20 out. I lose about 25 miles range off the top iff the car was cold soaked before I leave, and then I lose about 20% range steady state.by bryanlarsen

Pretty normal for most EVs to vastly overstate range. Rivian is the exception in my experience. But yes they’re very sensitive to terrain and temperature even if they aren’t exaggerating range.by SilverElfin

Why do apologists always resort to “are you holding it wrong”?This person is using their ev as a car, the same way they would use any other car in their possention. Evs are presented as ice car replacements but when their lack of ability as ice car replacements is pointed out the response is “well maybe you shouldn’t do that. WELL MAYBE THEYRE NOT ICE REPLACEMENTS /rant

Asking how fast they're going is a reasonable question. If they're driving over 75mph, a 40% range drop is not surprising.An ICE car comes nowhere near it's EPA rated mpg ratings at over 75mph either.

Sure, they're so far up in Germans automakers asses, they don't know it any other way.One of the reasons i quit my 20 year+ membership with them.
I mean - have some bias? Fine with me, i can read between the lines. Come up with ridiculous crap and reasons to favour domestic brands? There is a line, at least for me and many others that do know when they're intentionally ignoring, downrating, downplaying etc. etc. etc.
Another example? German IT magazine "c't" by heise recently featured a test (4/2026, page 16ff.), in cooperation with ADAC, about subscriptions in electric vehicles - actually one thing where Tesla shines (it's a flat 10€ per month, other countries get a 99$ a year deal) - others don't even bother listing prices until you order, for example.
With no single word that test mentioned Tesla (yet, priding themselves having queried 16 brands for information) - only in the final table overview, there indeed is one column for them.
The bias is showing, it's ridiculous and they can, as far as i'm concerned, go the way of the dodo.

Are you saying that the numbers published in that article are fake?If they aren’t fake, it’s pretty obvious why Tesla doesn’t get much of a mention.

Sorry you just make some accusations based on vibes.There are also Corean Cars in the Top 10, which makes sense as the Australian Article also rates them quite good.
Do you have any real criticism on their standardized range test?
by hermanzegerman
3/19/2026 at 11:35:44 PM
The US ranges are also way overestimated.My Tesla long range gets about 60% of advertised range in real world conditions. I'm talking stop signs every block, mountains you need to drive across, insanely hot days, i.e. the real world.
I knew that would be the case, but I really wish there was a crackdown on this. Advertised range should be the mean of the distribution, not the max.
In fact EV manufacturers should be required to publish the distribution and they should have to pay a KL divergence penalty on it that will be distributed to EV buyers as rebates. It would also require the courts to learn about KL divergence, which I would really love to happen. We need countries run by engineers, not clowns.

> Advertised range should be the mean of the distribution, not the max.Distribution of what? Assuming you mean the distribution of driving range achieved 'in the real world', how would that work before a car is sold? How often would it have to be updated in their advertising material? Over what sort of area would the distribution be calculated? How would anyone know if the advertised range of two different cars was even comparable?
Whilst the standardised tests could be improved, they are still the best way to compare products.
> should have to pay a KL divergence penalty on it that will be distributed to EV buyers as rebates
I get about 15% more range than advertised, should I have to pay a penalty for this?

There are many variables and scenarios, yes. This, however, is not an excuse not to provide some more data points that help people estimate what they are really getting...Anyway Tesla has data from all their cars, they could use that.

This really sounds like 'but think about a poor car vendor!'. And a poor car vendor definitely can't build at least 10 pre-production cars, run them with both a lightest and heaviest loads and different patterns and calculate the mean and use it instead of the one with the maximum distance with a minimal load, right?by justsomehnguy

A Chinese car rated under American regs would see a lower rated range.

3/20/2026 at 2:54:28 AM
My car is 605km in CLTC and 492km in WLTP. And it runs for about 450km before battery totally die, so I have to charge for every about 400~420km. A bit cold and totally no hill here in Shanghai.So for 900km CLTC, I think it will go like at least 600~650km easily.
by Bimos
3/19/2026 at 11:17:45 PM
Some of the reviews have been able to get as much as 80% of the rated range under ideal conditions.The CLTC doesn't measure actual highway usage well at all. If you drive a lot on highways and use the air conditioning you could be closer to 60% of rated range.
