GM confirms that the 2011 Chevrolet Volt will get 230 mpg city, and a composite fuel economy (city and highway) of more than 100 mpg according to draft regulations being developed at the Environmental Protection Agency (EPA).

This morning, General Motors CEO Fritz Henderson revealed that the extended-range electric car would achieve the first-ever fuel economy rating above 100 mpg if the current principles of measuring consumption in this new class of serial hybrids eventually is adopted.

How can the U.S. Environmental Protection Agency possibly measure fuel consumption that low? The answer, it turns out, is all in the assumptions. For a full discussion of the Volt's green numbers and that 230-mpg fuel economy, High Gear Media's GreenCarReports.com goes in depth to discuss how the EPA measures economy, how GM is estimating the 2011 Chevy Volt's numbers, and what happens when the new car hits the streets. "Your mileage may vary," GCR's John Voelcker sums it up.

Stay tuned for more today as TheCarConnection brings you the latest from a GM background event laying out the future of Cadillac, Buick, and the 2011 Chevrolet Volt--and read up on more Volt stories at AllCarsElectric and our colleagues over at GM-Volt.com.

  1. This is silly and not useful to the consumer. Not to take away from GM's achievement, but the volt is an electric car. Need to know how many KWh are needed to complete the tests to know how much it costs to run. Around here, electricity is $0.14 cents per KWh. Also need to know how much gas it consumes for both tests when the battery is depleted.

  2. WOW! What a breakthrough! Congrats to GM and the team that pulled this off. When I first heard about the Volt I always thought GM had a brilliant idea - the engine feeds the batteries, not the drive wheels. I suddenly have this surge of national pride. It feels great.

  3. I'm with Matt. This is the kind of advertising baloney that got GM in trouble in the first place. Among engineers, the real question is "what is the life cycle cost?" That would include the cost of manufacturing, electric and petrol fuel, and battery replacement costs after (n) years.
    This is GM selling the sizzle before the steak is ready. The steak may be baloney after all. What the EPA says means little to me.

  4. Hi,
    No, General Motors is correct. Electric cars are much more efficient with energy. I have a smaller electric car that gets more than 2000 mpg equivalent. Using either energy equivalence (gallons of gas per electric Kilowatt Hour) or price equivalence (dollars used per tank of gas vs pennies used per charge), the result is roughly the same. My lightweight vehicle is about 1/10th the mass of the Volt, too.
    GM should streamline their car with real-world aerodynamics rather than 'styling'. If they covered the wheel wells, put a flat pan on the bottom, and boat-tailed the back end they could have a higher top speed, higher mpg, and faster acceleration--and the car would weigh more and be much bigger! see www.aerocivic.com.

  5. This car has an Electric motor and a battery that must be recharged after 40 miles.
    For NiMH Battery pack:
    If you will be the lucky one, to kip this battery for 300 charge/discharge cycles, you need a new battery set after driving 12000 miles (40miles x 300 recharge cycles). If the cost of the battery is $5000, then you spend $0.4 per mile only in battery cost.
    For Lithium-ion Battery Pack:
    http://www.batteryuniversity.com/parttwo-34.htm
    If you will be the lucky one to kip this battery for 600 charge/discharge cycles you need a new battery set after driving 24000 miles (40miles x 600 recharge cycles). If the cost of the battery is $12000, then you spend $0.5 per mile only in battery cost.
    And after, 1 year on use, the battery must be recharged after 30000 miles. That means $0.66 per mile only in battery cost.
    Kilowatts, recharging the battery are extra.
    Oh, by the way, this car has a gasoline engine 40MPG, or $0.065 per mile.
    I bought a used Toyota Corolla, manual, on 2002 with 35000 miles. Now the car has 120000 miles and still makes 34MPG (Summer), or $0.076 per mile.
