Volt Birth Watch 106: 100 MPG Or Bust, Pt. 2
As we reported in our last exciting episode, a big, fat EPA rating on the Volt’s hood is crucial to the project’s success. The LA Times reports that the Volt’s vehicle-line director Tony Posawatz now claims that the EPA has “agreed to a testing method that will produce a rating of at least 100 mpg.” The EPA says it still needs time to determine a fair testing method for plug-in models that burn no gas in their initial EV range. But GM wants it done soon, dammit. Posawatz says The General would share mileage data from the Volt’s onboard computers to verify real-world performance if the EPA would grant the certification now. Posawatz estimates the Volt’s theoretical EPA rating at 120 mpg to 200 mpg, “depending on assumptions about how much gasoline is consumed after the battery loses its charge on the road.” Meanwhile, Don Foley of the Automotive X-Prize would like to remind everyone that “reliance on an mpg standard alone will soon be outdated and will not accurately reflect the need for higher fuel efficiency.” Word. The X-Prize’s mpge (miles per gallon equivalent) is a far better measure of energy use. Hey! Why isn’t GM entering the Volt in the $10m competition? Maybe the EPA mpg standards are easier to game.
