The U.S. Environmental Protection Agency on Thursday published an updated version of its Model Year 2015 Fuel Economy Guide. The guide and its online version contain information to help consumers find the most fuel-efficient cars available today.

Or not. The guide also lists the vehicles with the worst fuel-economy ratings. As you might expect, that list is full of high-performance cars, led by the Bugatti Veyron, a 16-cylinder, 8.0-liter sports car that achieves a combined city/highway fuel economy  of 10 mpg. The least fuel-efficient list also includes various models from Ferrari, Maserati, Mercedes, Rolls-Royce, Aston Martin, Bentley, Infiniti, and a Chevy Camaro that gets 14 mpg.

Here are the most fuel-efficient cars in eight different EPA classes:
