EPA confused by Chevy Volt's fuel economy

The EPA is not sure how to rate the Chevrolet Volt's fuel economy, and GM isn't at all happy about it.

The Volt can slip through about 85 percent of the EPA's test cycle without even firing up the gasoline engine. Using the EPA's standard formulas to calculate fuel economy, the Volt averages over 100 mpg. The EPA doesn't think that astronomical number is fair and has revised its tests with the requirement that the Volt finish the test with its batteries close to full charge, which means the internal combustion engine must run for the entirety of the test, dropping fuel economy to about 48 mpg.

GM, of course, argues back that the EPA's new test isn't fair because the test isn't representative of the way the Volt was designed to operate and doesn't reflect the Volt's plug-in option for battery charging.

The truth lies somewhere in between, but the EPA rating assigned will play a big role in whether consumers think the $40,000 Volt is a good deal compared with the Toyota Prius and the upcoming, and even less expensive Honda Insight.
