Winter driving conditions and cold temperatures can have a significant effect on a vehicle’s fuel economy. For a conventional gasoline-powered vehicle, fuel economy at 20°F is about 12% lower than at 77°F for short-trip city driving. For very short trips of just 3 to 4 miles, fuel economy can drop by as much as 22%. For more information on the effects of winter conditions on fuel economy, visit
