Imagine a sun-swept Texas afternoon in 2015. After the roar of a ceremonial flyover, a Texas Motor Speedway crowd of 200,000 rises to its feet in anticipation of NASCAR's signature moment.
The celeb du jour grabs the microphone and bellows, "Gentlemen, start your engines!"
As the fans join in a full-throated cheer, 43 of the world's best drivers reach down and press a button. What follows is unprecedented: pin-dropping silence, save for 43 small clicks.
If NASCAR goes electric, CNN wonders, will fans stick around? Do they love the roar or the engines or the speed at which the cars move? Will they be satisfied with one but not the other? NASCAR isn't exactly at the forefront of automotive greenery (although it is thinking about it), but a U.S.-built Volt might be good enough to change some hearts and minds, no?
