alt Hacker NewsThe 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. :)

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