SUVs and Trucks That Cost the Most to Gas Up

With the current national average price near $4 a gallon for regular gasoline, all 10 models from Consumer Reports’ tests cost over $100 to fill their tanks from empty. (In February, only three cost over $100 to fill.) The vehicles on this list all have large gas tanks capable of holding 21 to 36 gallons, and their fuel economy, based on CR’s tests, ranges from 16 to 21 mpg overall.

In fairness, some models have competitive fuel economy, but massive fuel tanks mean significant costs at the pump when filled from empty. For example, the Ford F-150 Hybrid made the list this year. Its 20 mpg overall is decent, and it has a massive 600-mile range, thanks to its 30.6-gallon tank. But fill-ups can require a truckload of cash.

These extreme examples show the maximum costs for fill-ups. Your actual costs may be higher or lower depending on your location and will vary as gas prices fluctuate.

When buying a vehicle, consider the impact on operating costs if gas prices rise by a dollar or more once again. This includes being aware of whether the vehicle requires premium gas, which adds almost a dollar a gallon, a penalty that pushed the Jeep Grand Wagoneer near the top of this list and led to the inclusion of several midsized luxury SUVs rather than full-sized models like the Ford Expedition and Ram 1500.

But no matter what you drive, there are ways to improve fuel economy and save at the pump.
