The Chevy Volt’s driving range is reduced by cold or hot weather. The EPA estimates the Chevy Volt can travel 35 miles on a fully charged battery according to an article written by Doug Wernert, Chevrolet VoltAge Community Manager.   This will vary due to the weather conditions he adds.   If it is cold, using the car heater and front window defrost will have a “high/maximum Impact” on the Volt’s range.  And of course, in hot weather the A/C unit has “high/maximum impact” on range.  (Do you have the feeling that the range estimates are often at odds with the last news release you read?)  Does the EPA account for the weather in their estimated fully charged battery range?  If not, then it would seem that 35 miles might only be good on optimal days, says 68F or something like that (no A/C, no heat) and would result in a lower figure for the rest of the time.   A chart that accompanied Wernert’s article listed some other activities that resulted in “high/maximum impact” on the range.  These are

High speeds (70+mph)

Aggressive Accelerations

Steep incline

So, no driving in the mountains with the pedal to the metal in cold weather.
