All EVs lose range in the cold, and it's not just about cold batteries: there are higher demands for cabin heating, higher rolling resistance from stiff tires on cold, slushy or snowy roads, and more requirements for use of wipers and defrosters.
All EVs benefit from preconditioning and prewarming. The major advantage of LFP is that you can plug it in, charge it to 100%, and leave it there while the cars waits in the garage for the next time you venture out.
Bottom line: if I was given the choice between a nickel (NCA) SR+ and an iron (LFP) SR from Fremont, I'd take the iron every time. I'd then pocket the difference in purchase price, and leave it plugged in all the time in my garage.
Oh, and I'd join the Tesla Network too so that it's out earning money for me twice a day (2 x rush hrs) while its not charging... That's basically a free LFP 3/Y that'll last for 1 million+ miles.
BTW, we learned on Bty Day that the $25K 'Model 2' will have Model 3 running gear (which includes the proven 1 million mile life rating for the drive unit) and the more economical LFP pack. So will there be a
'hot hatch ' version of Model 2 with NCA nickel batteries? Well, this is Tesla soo...
Cheers!
