GM CEO Fritz Henderson was all smiles when he announced the Chevy Volt's 230 mpg city rating yesterday. But the Internet digested the news in its own way, and there was some understandable confusion and criticism of the very big, very bold mpg claim. While the EPA put a damper on GM's numbers, that was mostly a way to say that it's too early to tell. GM representatives made it clear that they don't see the 230 number as unrealistic or setting Volt fans up for disappointment when the agency finally gets to test actual vehicles sometime next year. However, others were less diplomatic.

Darryl Siry, EV aficionado and former CMO at Tesla, was quick to call the 230 number "unrealistic," adding that, "the problem is that anytime you try to get to 'miles per gallon' using vehicles that don't necessary use 'gallons' you end up in a very strange debate with very strange outcomes." Indeed. Siry made sure to say that it's the EPA method (still in development, and one we don't know much about yet) and not only GM that's to blame here.

Over on What is 230?, someone who claims to be a "GM employee who works directly with people who work on the Volt" wrote in to say that the number is a "mis-leading gimmick of a marketing tactic."

In the least surprising response, Bob Lutz has nothing but good stuff to say about the 230 campaign and the rating. He says the hype was made "For one simple reason: We're proud of it."
