I've skimmed the forum and read threads about decreased range, but don't see anything about speed limitations in freezing temps. I just bought a 2014 ED and the weather turned super-cold. I pulled onto the freeway and couldn't crank out 50 mph. Test drives before I bought the car were in somewhat warmer weather (30s and 40s) and were no problem. Plenty of zip for me. Now temps are in the single digits (F) and the car just has no interest in scooting along. I was prepared for limited range during the winter, but didn't think I'd be trying to drive a totally gutless car in the dead of winter The Mercedes salesman just had vague comments about how electric cars don't work the same when it's cold. Any words of wisdom from the more experienced owners who live where it's cold? ...other than "move to California", which I am not gonna be able to do!
