With the "Green Car Challenge" segment of his soon-to-be-terminated 10 pm show, Jay Leno has been a frequent proponent of electric cars--among them the upcoming electric version of the Ford Focus.

Now that car has a name, as Ford happened to mention during a 2010 Detroit Auto Show press event.

The company was talking about its decision to bring design and production of advanced battery packs for electric-drive cars "back home" to Michigan, but in the handout, the car was referred to as the Ford Focus Electric.

2013 Ford Focus Electric

No model year was specified, but since the new 2012 Ford Focus--our Best Green Car of the 2010 Detroit Show--will go on sale early next year, we'd be that the Focus Electric model will be dubbed a 2013 model.

A test version of the electric Ford powertrain, installed in a current European Focus model painted bright orange, had a cameo on an early September cameo on the then-new 10 pm Jay Leno Show.

Leno gets dibs, journos get leftovers

Meanwhile, journalists and conference attendees all over the country have made do with driving an earlier Focus EV prototype, installed in a current U.S. Focus--whose basic mechanicals now date back a decade.

Celebrities and cars are a topic of endless fascination, but Leno is a serious car aficionado whose collection of several hundred historic vehicles may well be the broadest and best in the country.
