20 Luxury Cars With the Best Gas Mileage

MAIN_Geribody_iStock_78202687_LARGE.jpg

Thanks to the drop in gas prices over the past several years, it’s a lot less painful at the pump. In fact, Americans are expected to spend $20 billion less on gas this year than in 2015 as a result of lower prices, according to projections by GasBuddy, a source of real-time gas prices.

But that doesn’t mean it’s cheap to fill up your car, especially if you have a gas-guzzler. That’s why fuel economy is still an important factor to consider when buying a car — especially a luxury car that might require pricier, higher-grade gasoline.

The average fuel economy of new vehicles sold this year is 25.3 mpg, according to the University of Michigan Transportation Research Institute. If you’re in the market for a luxury car that’s not also a hybrid, GOBankingRates found 20 that get good gas mileage, and 16 of them get more miles per gallon than the average — which translates to savings at the pump that can help offset the higher cost of a premium vehicle.

The cars on this list are among the best-selling luxury vehicles, according to consumer ratings and research company J.D. Power and car-buying resource Car.com. If you want to save money on a luxury car, click through to find out which ones get the best gas mileage.
