GM Says New Car Is Capable of 230 MPG
General Motors announced Tuesday that its forthcoming electric vehicle, the Chevrolet Volt, will get fuel economy of 230 miles per gallon in city driving, an achievement that both accelerates and befogs the industry's race to produce more efficient cars.
The Volt will become the first mass-produced vehicle to obtain a triple-digit mpg rating, the company said, and some industry analysts agreed that the car may put the company a step ahead of competitors building plug-in hybrids.
"The GM vehicle is the best one in the country based on what we've seen," said Don Hillebrand, director of transportation research at the Energy Department's Argonne National Laboratory, the nation's leading lab for plug-in vehicles. "But it's hard to tell -- other companies could be keeping theirs secret."
