DOE, EPA Release the 2012 Annual Fuel Economy Guide
The 2012 all-electric Mitsubishi i-MiEV was rated most economical with a 112 miles per gallon average, according to the 2012 Fuel Economy Guide.
DOE and the U.S. Environmental Protection Agency (EPA) released the 2012 Fuel Economy Guide on November 16th. The guide provides information that can help consumers choose more efficient vehicles that save money and reduce greenhouse gas emissions. While fuel-efficient vehicles come in a variety of fuel types, classes, and sizes, many new advanced technology vehicles debut on this year's annual list of top fuel economy performers. The 2012 all-electric Mitsubishi i-MiEV topped this list, after a conversion from gas-to-electric was factored in to give it a 112 miles per gallon (mpg) average. The Nissan Leaf electric vehicle, the Azure Dynamics Transit Connect Electric Van, the plug-in hybrid Chevrolet Volt, and last year's leader, the Toyota Prius hybrid, rounded out the top five spots.
Fuel economy leaders within each vehicle category—from two-seaters to large SUVs—include widely available products, such as conventional gasoline models and clean diesels. Some 2012 models will be voluntarily displaying a new fuel economy and environment label that provides consumers with more comprehensive fuel efficiency information, including five-year fuel costs or savings compared to the average vehicle, as well as new greenhouse gas and smog ratings. These labels are will be required in model year 2013.
The online rankings include the vehicles with the lowest fuel economy. Each vehicle listing in the guide provides an estimated annual fuel cost. The estimate is calculated based on the vehicle's mpg rating and national estimates for annual mileage and fuel prices. The online version of the guide allows consumers to input their local gasoline prices and typical driving habits to receive personalized fuel cost estimates.
