Green is still a red-hot buzzword in the auto industry, with carmakers competing to showcase their commitment to fuel savings. It’s not all altruistic; carmakers have to meet tougher fuel-economy standards between now and 2025. And not every winner is a paragon of green technology. But each vehicle we spotlight is the least thirsty in its class based on annual fuel cost.
The annual fuel cost assumes 15,000 miles of combined city and highway driving each year and fuel prices of $3.20 a gallon for regular, $3.40 for premium and $3.95 for diesel. Models must make our top 25 in their category to be eligible, and no model can win the award if another trim level of that model has won in a lower-price category.
