Chevrolet Volt Drivers Pass 500 Million Miles On Electricity

Since its launch in December 2010, owners of the Chevrolet Volt extended-range electric car have steadily racked up miles driven solely on electricity from the grid.

They recently reached a significant collective milestone: more than half a billion electric miles.

The total is based on data from owners who let Chevy track their mileage via the Onstar telematics system, meaning that the actual total electric miles are likely up to 20 percent higher.

The total reflects the fact that most Volts operate on electric power from the grid, stored in their lithium-ion battery packs, the majority of the time.

According to General Motors, Volt owners do more than 63 percent of their driving on electricity, and travel an average distance of 970 miles between fill-ups.

And Volt owners showed their enthusiasm for zero-emission motoring right out of the gate.
