The Chevrolet Volt may get a fuel economy rating of 100 MPG or more from the U.S. government.
With companies pushing just highway mileage in ads to boost their thrifty image, a 100 MPG ad headline would surely grab national attention. The Volt may have the lowest ad budget in the history of GM when it launches in late 2010.
General Motors is asking the EPA to declare the Volt an electric vehicle for regulatory purposes. The California Air Resources Board has given the Volt preliminary certification as an electric.
Vehicles put through government paces for fuel economy ratings are run on an EPA test loop that mimics both city and highway driving, to measure pollutants and provide data for fuel economy. For electrics, the government uses a Department of Energy formula to translate energy use into some equivalent of miles per gallon of gasoline.
The Tesla roadster, an all-electric vehicle, is rated at 244 mpg.
GM refers to the Volt as a “range-extended” electric, which is designed to go 40 miles on all-electric power. Then a small internal combustion engine would kick in to extend the range.
