DOE and the U.S. Environmental Protection Agency (EPA) released on November 3 the 2011 Fuel Economy Guide. The listing provides information about estimated mileage and fuel costs for model year 2011 vehicles. For the first time, the guide includes medium-duty passenger vehicles, which are generally large sport utility vehicles (SUVs) and passenger vans. EPA and DOE will provide additional fuel economy information online as more information about 2011 vehicles, including electric and plug-in hybrid cars, becomes available.

Fuel-efficient models come in all types, classes, and sizes. The Fuel Economy Guide can help consumers identify the most fuel-efficient vehicles that meet their needs. Overall, hybrids are the best fuel economy performers, but the 2011 fuel-economy leader list also includes fuel-efficient clean diesels as well as gasoline models. Each vehicle listing in the guide provides an estimated annual fuel cost. The estimate is calculated based on the vehicle's miles per gallon (mpg) rating and national estimates for annual mileage and fuel prices. Toyota's automatic hybrid Prius was the leader in the midsized category, with 51 mpg city and 48 mpg highway rating. The newly added SUV category had a three-way tie among the Ford Escape Hybrid FWD, the Mazda Tribute Hybrid 2WD, and the Mercury Mariner Hybrid FW. All three automatics registered 34 mpg city and 31 mpg highway.

DOE and EPA also maintain the Web site www.fueleconomy.gov to help consumers make informed fuel economy choices when purchasing vehicles and to help them achieve the best fuel economy possible from cars they own. The site allows consumers to enter their local gasoline prices and typical driving habits to receive personalized fuel cost estimates.
