Tesla cold-weather range, EV driving in Michigan.

Range tip: Teslarati’s Rob M. has meticulously measured the range of its Model S in sub-zero conditions. Every ten-degree drop in temperature decreases the real range by 10 percent. On wet roads however, the Tesla can lose up to 25 percent range.

Reading tip: Driving an electric car in wintry Michigan poses its own kind of problems. Not only is the state pretty cold but it also offers three DC fast-chargers only, one of them is a Tesla-only fast charger, so it is of no use to the e-Golf on trial here.
