By now you guys probably know a lot about the Chevy Volt. We know that it can do 40 miles on battery-power alone, after which a 1.4L 4-cylinder engine will kick in allowing for a range of at least 300 miles. We know that it takes anywhere from 3 hours to 8 hours to charge depending on the amount of volts. What we don’t know is how many miles per gallon the Volt will deliver.

According to GM spokesman Rob Peterson, GM has asked the EPA to declare the Volt as an electric vehicle for regulatory use. That would give the Volt an EPA rating of more than 100 mpg which will be a strong selling point for GM.

A regular car gets its EPA rating, which consists of city and highway driving, to measure tailpipe pollutants and other data to calculate for fuel-economy. However, for an electric car with no emissions, EPA uses a Department of Energy mathematical formula to convert energy into an equivalent of miles per gallon.

For example, the Tesla Roadster, which used that formula, has an EPA rating of 244 mpg.
