The New GM, Starting with a Big Lie

"Chevrolet Volt Expects 230 Mpg In City Driving"

That's the banner at the top of GM's press release for the Chevrolet Volt, its forthcoming plug-in hybrid. Very impressive, but not true. GM expects the Volt to go 40 miles on its battery, during which time its mpg is infinite: it goes 40 miles on no gallons, hence 40/0 = infinite.

So what mileage does the Volt get when traveling beyond the range of its battery? GM isn't saying. They're hiding behind a "draft EPA federal fuel economy methodology for labeling for plug-in electric vehicles." I hope EPA figures out a more useful methodology; meanwhile GM is being deceptive.

Too bad. Lying is always bad, but why lie when the truth about the Volt is remarkable enough. Maybe it's in their DNA?
