2008's most fuel-efficient sports cars/coupes

Fuel-efficient cars by body style

Choosing a new sports car/coupe? Weigh the impact of your choice on your wallet and on the planet. The following sports cars/coupes are ranked by city miles per gallon (MPG), followed by highway MPG based on the Environmental Protection Agency's Fuel Economy Guide for the 2008 model year. (For details of the testing, see the notes below.)


Rank Model MPG: city/hwy Annual fuel cost * Carbon footprint
(tons/yr of CO2)

Notes:

* Annual fuel cost is based on an assumption of cars driven 15,000 miles annually, 54 percent on the highway, 46 percent in the city, and a fuel price of $4.08 per gallon. Visit the EPA's Web site to calculate annual fuel costs using a different fuel price or annual miles for a specific vehicle.

This year, the EPA has changed the way it estimates MPG to more accurately reflect real driving conditions. Estimates reflect the effects of: faster speeds and acceleration; air conditioner use; and colder outside temperatures. The tests lower MPG estimates for most vehicles compared to previous years. Miles per gallon will vary for models with different vehicle specifications. Driving habits will also affect MPG.

Each model is allowed to appear on the list only once, except the Honda Civic, which appears on the list twice because of its availability in both regular gasoline and gasoline-electric hybrid versions.
