DETROIT – Chevrolet affirms its commitment to fuel solutions and building refined, eco-friendly vehicles with the debut of the U.S. production version of the Cruze sedan at the Los Angeles Auto Show, on Dec. 2. The Cruze, along with the much-anticipated Volt electric vehicle, will give visitors to the L.A. show a close-up view of Chevrolet’s expanding lineup of gas-friendly to gas-free products. “With expected highway fuel economy up to 40 miles per gallon, Cruze will be extremely gas friendly while the Volt electric vehicle can be operated gas-free," said Brent Dewar, vice president, Chevrolet. “Chevrolet's focus is on forward-looking...

General Motors announced with great fanfare last week that its new Chevy Volt will get 230 miles per gallon. Not to be outdone, Nissan quickly announced that its new electric car, the Leaf, will get 367 mpg. If you believe that, we have a couple of auto companies in Detroit to sell you.

"If you are using coal-fired power plants and half the country's electricity comes from coal powered plants, are you just trading one greenhouse gas emitter for another?"...

The Chevrolet Volt's 230 mpg number continues to be questioned. The latest to criticize is Bill Ford, who takes issue not only with the General Motors-approved 230 figure, but also Nissan's claim that its Leaf EV will get 367 mpg. The real culprit here, Ford said, is the EPA's methodology, which he argues is meaningless. "This question devolves into madness," Ford reportedly told Green Car Advisor: "The government will have to come up with a meaningful number for customers - a user-friendly label. And I think they will. I can't dispute that number, but I'm not sure it's relevant to...
