GM’s Figure of 230MPG For The Volt Was Wrong

Remember when GM claimed that the Volt could get around 230 miles per gallon? Well, think again. It was calculated using a government formula that never got final approval.

"We just don’t know right now" what the new number is likely to be, Micky Bly, executive director of global electrical systems for GM, said Wednesday at GM’s battery factory in Brownstown, Mich.

The Volt is an electric car and we’re sure most of you already knew that. It can go 40 miles on its batteries alone, but it also has a gas engine that is used like a generator. To find out the mileage for that would take a mathematician and the government doesn’t appear to have one.

The gas engine’s mileage is dependent on how charged up the battery is, which can vary based on each car’s charge. The Society of Automotive Engineers is currently working on a way to calculate mileage stuff for plug-in hybrids and electric cars. The organization expects the government to use its new standard for all future plug-in vehicles.
