So far as I know, Tesla is the first EV manufacturer to manage this feat (with an LFP battery, no less !) as shown by Bjorn Nyland in his 1000 km challenge.

Most of the magic comes down to two things:
1. Battery pre-conditioning before DC fast charging
2. Scavenging heat from charging to use for cabin heating.
This really is a big deal, since until now the Achille's heel of EV Vs ICE has been winter driving. And although not mentioned by Bjorn, the feat is only really possible with a well developed and communicating DC network so America is still out in the cold in many areas. Nonetheless, the EV now has a proven path to winter performance about on par with summer.

As for the LEAF ? Well .... it has issues. Today was our first cold day of winter. I pulled into an EA this morning with a SoC of 25% and pack temp of 27F. I only needed to reach a SoC of ~ 50% to get home. Charging started out at 15 - 20 kW, but by the time SoC was 35% power had dropped to 8 kW. I also noticed that cabin heating power reduced in equal amount the power sent to the battery. I was not expecting that with DC charging.
Yeah.
Signed, Cold feet.
