Re: German magazine compares real-world electric-car ranges, efficiencies in cold weather

41 isn't cold. Maybe for san diego.

I'd rather see the test done properly with legitimate winter conditions. Doesn't have to be -30 F, but 10F would be a great test and each of those cars would do much, much worse. Have them sit for 8 hours, too, so you get a nice cold-soaked battery, climate control has to be on high due to low ambient, and then see how the test goes. This would better approximate somebody who's wondering if they can make it to work and back on a truly cold day.

I'm sure they could do one now, but you can only test with the weather you've got. I'd love to see some mag in the U.S. do a similar test in say Bismarck, N.D. (maybe MSP is more reasonable) in January.
