Featured EV and winter tests posted

It's not just freezing temperatures, but it's typically combined with ice & snow & snow tires Dynamics

 

Looks like they are comparing WLTP to road tests. WLTP is better than NEDC, but still optimistic. For that Model 3, it is 20% better than its EPA rating. Most of those cars will see a loss with summer testing.

 

I go from a high in the best weather of about 6 miles per kWh, to about 4 in the worst weather around here.
Bolt has electrically heated cabin coolant, which sucks up the juice, but the heated seats and steering wheel help minimize it.
An electric windshield would be a help

 

I wonder what the price difference is between Tesla and polestar similarly equipped to get the same winter range and much better summer range for the Tesla

 

The models tested aren't a like comparison. The Polestar 3 is a SUV in the Model Y's class. The Polestar 3's WLTP rating is very close to its EPA; 348 to 350 miles. They must be under selling it from the actual WLTP results. The Model Y is 337 miles.

The range of the Model 3 the article tested on the WLTP is 436 and 363 on the EPA. It went 330 miles on the winter test, or a 9% reduction from EPA. The Polestar 2's EPA range is just 254.

The winter test more shows how poorly the WLTP can represent what an owner can achieve. I suspect it doesn't have a cold or hot cycle like the EPA does. it also shows which manufacturers acknowledge the WLTP's failings in their official published ranges.

The Polestars are $30k+ more than the Teslas in the US. They aren't efficient BEVs, and have bigger batteries.

 

Temperature is a problem. But preconditioning with a scheduled departure time works great:


I've been seeing an estimated range on road trips of about 200-210 miles. Let the grid heat the battery and cabin.

My 2017 BMW i3-REx sees similar loss of EV range but a warm day, and back to normal.
