Chevrolet Volt owners in America have surpassed 100 million electric miles in two years, saving 5 million gallons of fuel, and $1,300 a year in fuel cost. So collectively they’ve saved $21 million worth of gasoline in that period, and tons and tons of CO2. Guess we can declare the Volt a success now.

The Volt works because it doesn’t rely only on electricity to run the car. It has a small gasoline engine as the range-extender, thus eliminating range anxiety, which is a killer in normal EVs. The good thing is, most Volt owners rarely even use the range extender. Chevy says they drive approximately 900 miles, or a month and a half, between fill-ups.

So the gasoline engine only kicks in on longer trips out of town. For urban use the plug-in charging system works well. The Volt can cover 38 miles using a full charge of electricity stored in its 16.50-kWh lithium-ion battery.

“The best sign of a great product is when your customers are the most satisfied in the industry,” said Cristi Landy, Chevrolet Volt marketing director. “Volt owners have found the Volt is not only fun to drive, but provides technology and performance where consumers need it most.”

This is the second year in a row the Volt has topped the satisfaction survey of one of the leading consumer testing organizations in the United States.

“My commute is 55 miles round trip, but with the Volt I use 80 percent less gas and save over $150 each month,” said Farris Khan from southeastern Michigan. “Plus the Volt is really fun to drive because of its instant torque; driving anything else feels like yester-tech!”
