Chevrolet Volt Smashes EPA Fuel Economy Rating Methods

The day is finally upon us where passenger cars running on more than straight ol' war starting fossil fuel are hitting the mainstream. While this is great for consumers all around, it is forcing the Environmental Protection Agency (EPA) to rethink their methods for testing a car's fuel economy. The last generation of hybrid cars, like the Toyota Prius and Honda Insight, ran their gasoline and electric motors at the same time, making fuel economy estimates easier.

But how do you test fuel economy for a car like the Chevy Volt, which will be able to run for around 40 miles on electricity alone? Traditional EPA test methods include stretches of highway and city mileage around 11 miles long, which the Volt can pull off without ever using a sip of fuel. So how do you rate it? Many have called for a new EPA testing system that will be fair to all new cars and automakers, and still give consumers a good idea what they can expect to pay at the pump.
