Volt receives EPA ratings and label: 93 mpg-e all-electric, 37 mpg gas-only, 60 mpg-e combined
24 November 2010
The US Environmental Protection Agency (EPA) has issued its fuel economy ratings and accompanying fuel economy label for the 2011 Chevrolet Volt extended-range electric vehicle. The dual-fuel vehicle (electricity and gasoline) is rated at 93 miles per gallon-equivalent (combined city/highway) in all-electric mode (36 kWh/100 miles) and 37 mpg US in gas-only mode (2.7 gallons per 100 miles).

All-electric range under the EPA rating is 35 miles; total range for the car is 379 miles.
The two modes are combined into an illustrative 60 mpg-e combined rating for the vehicle. On a conference call discussing the numbers, Doug Parks, Chevrolet Volt Global Vehicle Line Executive noted that the combined figure will vary widely based on driving patterns. I.e., more electric driving pushes it closer to the 93 mpg-e figure; less pushes it closer to the 37.
In an attempt to convey to consumers the variability of the fuel economy outcome based on miles driven between charges, the EPA also includes a table showing fuel economy and electricity consumed for 5 different scenarios: 30, 45, 60 and 75 miles driven between a full charge, and a never charge scenario.
Under that last scenario (the gas-only scenario), the 37 mpg figure results from 35 mpg city, 40 mpg highway.
