20-30ish % efficiency drop in capacity IIRC and, model depending, they've designed ways to mitigate it.

Could be better could be worse I guess.

From what I’ve read the newer ones charge more easily and last longer in the cold than older ones did. I’d love to hear from someone with some experience though. I don’t know how many Hexbears are running around with newish Chinese EVs in cold climates for comparison though.

Don't EVs generally suck in the cold?

Yes, but it's a stereotype that Russians only live in areas where's "it's cold". If you look at population densities/distributions of Russia, you'll find that they live pretty much the same latitudes as other European countries.

That big blog towards the left is Moscow, the largest urban agglomeration in all of Europe. Aside from St. Petersburg (~5 million people), pretty much all the big urban agglomerations are on the same latitude or more southern than Moscow. And Moscow is on the same latitude as Copenhagen and Edinburgh. Yes it gets a little colder there in winter, but that's just 2-3 months. No reason why EVs wouldn't work in Russia.
