The 10 Cars That Cost the MOST to Fuel in 2026 (And 10 That Cost the Least)

Some cars cost a fortune to buy. Others cost a fortune just to KEEP FUELED. And in 2026, the difference between America's most expensive and least expensive vehicles to fuel might surprise you. Imagine two drivers traveling the same 15,000 miles in a year. One spends thousands more at the pump, simply because of the vehicle sitting in their driveway. Same roads. Same distance. Very different fuel bills. We're talking about powerful sports cars, massive trucks, luxury SUVs, efficient hybrids, and everyday vehicles that can stretch a gallon of gasoline much further than you'd expect. But here's what makes this comparison especially interesting. The vehicle with the highest sticker price isn't necessarily the one with the highest annual fuel cost. And the cheapest car to purchase isn't always the cheapest to drive.
