Electrifying formula one [News]

Formula One drivers have always needed physical stamina to endure crushing turns and long races. Now they'll need to be good sprinters, too. That's because in lieu of a tire-change pit stop, drivers of the new allelectric Formula E series will sprint from one car to another midrace-twice. The car swap will allow pit crews to recharge the batteries. The relay-race aspect of Formula E harks back to the Pony Express, but the car itself, unveiled in September at the Frankfurt Motor Show, in Germany, looks ahead to the possible future of electric cars.
