It was a long, cold winter for much of the U.S., and if you live in one of those Snowbelt states you might have noticed that your fuel bills rose whenever the mercury sank, your car working longer and harder to get both the engine and passenger compartment up to temperature. The good news is that hot weather actually can reduce your fuel consumption – at least if you follow some basic tips.
While your engine warms up faster – requiring less fuel – you need to think about ways to keep the passenger compartment cool without putting the air conditioning on at full blast, cautions the Department of Energy (DoE) and other automotive experts.
“Under very hot conditions, AC can reduce a conventional vehicle’s fuel economy by more than 25%,” notes new guidelines posted on Fueleconomy.gov. And the impact of running your air conditioning in a hybrid, plug-in or battery-electric vehicle “can be even larger on a percentage basis,” it notes.
