2011 Chevrolet Volt gets a triple dose of EPA mileage numbers

After finally coming up with fuel-economy equivalency figures for the pure-electric 2011 Nissan LEAF, the EPA has now released a similar but even more involved set of ratings for the 2011 Chevrolet Volt. According to the EPA, the Volt returns a 93 MPG equivalent number when operating on pure electric power, nets 37 MPG when powered with electricity provided by its gasoline engine/generator and nets a 60 MPGe mark when operating in a combined mode.

Like the LEAF, the 2011 Chevy Volt will carry this plus a good deal more related information on a supplemental sticker that will be part of its standard Monroney label. Among other pertinent facts, the EPA has determined that Volt charge time on a 240V circuit would be four hours, that the average all-electric range of its 16kWh lithium-ion battery pack is 35 miles and that the 1.4-liter range-extender engine will provide enough per-tank energy to deliver an additional 344 miles. The label also indicates that the annual average cost to run the Volt on electricity alone would be $601, while operating it in gasoline-only mode would cost $1,302 at current gas prices. Like the Nissan LEAF, the Chevy Volt also nets overall "Best" environmental impact ratings when compared to other compact vehicles as well as in the areas of greenhouse-gas and other-air-pollutant emissions.
