Cold weather affects all gasoline vehicles, my Dodge gets 15-18mpg summer and 9mpg in the winter.
The Volt for me can get over 50mpg pure gas mpg when it's hot (not including electric)
But is lucky to average 36mpg gas only in the winter.
Colder it is, coupled with short trips the worse it gets.
The volt in other words is like every other car in winter sub 15 degree days, just that it has a few tricks a normal car doesn't, especially when on longer trips
