24EPA still not settled on MPG labels for plug-ins, Volt unlikely to get 230 mpg

Last week at the Society of Automotive Engineers World Congress in Detroit, we spoke with Dr. Pete Savagian of General Motors about what the Chevrolet Volt's fuel economy sticker would look like. Last summer, former GM CEO Fritz Henderson made a big splash when he announced that the Volt was getting approximately 230 miles per gallon combined. However, that number was based on a draft proposal by the EPA for a testing methodology for plug-in vehicles.

Last summer former GM CEO Fritz Henderson made a big splash when he announced that the Volt was getting approximately 230 miles-per-gallon combined. However, that number was based on a draft proposal by the EPA for a testing methodology for plug-in vehicles.

76Report: Chevy Volt will get 50 mpg once the battery is used up

Eight months ago, General Motors made a huge deal about how the Chevrolet Volt will get 230 miles per gallon. Of course, the company admitted that this isn't what drivers will actually experience when they use the car, just that the Volt is "expected to achieve city fuel economy of at least 230 miles per gallon, based on development testing using a draft EPA federal fuel economy methodology for labeling for plug-in electric vehicles."

13REPORT: EPA planning to address outlandish fuel economy claims of electric cars

The EPA is aware that range-extended electric vehicles can game the current fuel economy test to deliver mileage estimates way up in the stratosphere. It makes for impressive advertising, like General Motors' touting of the Chevrolet Volt's estimated 230 mpg, but the EPA wants to give a more realistic reflection of the fuel efficiency of these types of cars, and it's not alone.

59Chevy Volt and 230 mpg: Negative reactions abound, but not from Bob Lutz

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 final

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 claim. The EPA was the most official source to put a damper on GM's numbers, but that was mostly a way to say that it's too early to tell. GM representatives were very clear to us that they don't see the 230 number as unrealistic or setting Volt fans up for di

80How did GM arrive at 230 mpg for the 2011 Chevrolet Volt?

Neither General Motors nor the EPA are making declarative statements about how, exactly, the 2011 Chevy Volt will achieve it's much-touted 230 mpg rating that was announced today. GM's most clear statement (available in full after the break) says that some consumers "may be able to be in pure electric mode on a daily basis without having to use any gas" and that "key to high-mileage performance is for a Volt driver to plug into the electric grid at least once each day."
