Bugatti Veyron Super Sport exhaust

Every year the Environmental Protection Agency (EPA) produces a list of the best and worst cars for fuel efficiency and not surprisingly this year’s worst offender is the 2011 Bugatti Veyron--a car fitted with a quad-turbocharged 16-cylinder engine displacing no less than 8.0-liters.

This sledgehammer of an engine is enough to take the Veyron beyond speeds of 250 mph with aplomb but it also returns one of the worst fuel economy ratings of any production car we’ve seen in a long time. According to the official EPA numbers, the 2011 Bugatti Veyron returns a fuel economy of 8 mpg in the city and 15 mpg on the highway.

At the other end of the spectrum is the most fuel-efficient model currently on sale, the 2011 Toyota Prius, which returns a fuel economy of 51 mpg in the city and 48 mpg on the highway. Ahh, but we know what you’re all asking: Can the Prius take you from 0-60 in 2.5 seconds?

In all seriousness, the results come as no big surprise. Other top offenders include the 2011 Ford E-350 Wagon, which returns 10 mpg in the city and 13 mpg on the highway, and the 2011 Mercedes-Benz G55 AMG, which returns 11 mpg in the city and 13 mpg on the highway.

Below is the EPA's list of the ten most fuel efficient models:

1.  2011 Toyota Prius: 51/48 mpg City/Highway  
2.  2011 Ford Fusion Hybrid, Milan Hybrid, Lincoln MKZ Hybrid: 41/36 mpg City/Highway 
3.  2011 Honda Civic Hybrid: 40/43 mpg City/Highway 
3.  2011 Honda Insight Hybrid: 40/43 mpg City/Highway 
4.  2011 Honda CR-Z (auto): 35/39 mpg City/Highway 
5.  2011 Lexus HS 250h: 35/34 mpg City/Highway 
6.  2011 Ford Escape Hybrid, Mazda Tribute Hybrid, Mercury Mariner Hybrid: 34/31 mpg City/Highway 
7.  2011 Smart Fortwo: 33/41 mpg City/Highway 
8.  2011 Nissan Altima Hybrid: 33/33 mpg City/Highway 
9.  2011 Lexus RX 450h: 32/28 mpg City/Highway
