Friday evening, when perhaps not a lot of people were watching, a virtual odometer ticked over on the Chevy Volt website.
At that hour--about 7 pm Eastern--it showed that Volt drivers had covered 100,000,000 miles on electricity in their range-extended electric cars.
(The actual total is about 25 percent higher, since the counter only logs miles from those 80 percent of owners who've agreed to let Chevy track their performance via the Onstar telematics system.)
That's out of the roughly 160,000,000 miles those tracked Volts have traveled in total.
Which reflects the fact that Volt owners cover almost two-thirds of their total distance on electricity--higher than General Motors had expected, we imagine, when it launched the Volt in December 2010.
In fact, GM will soon release an app that lets Volt drivers compete on electric miles driven.
And the Volt electric-mile counter continues to rise. When this article was published--just two and a half days later--the total had already risen 1.2 percent.
And so forth.
And that's just the start.
When will we reach 1 billion electric miles driven in the U.S.? Ten billion?
