Electric vehicles, hybrids flaunt advantages on the race track

 Prominent racing teams, including Marussia and Williams, are racing this year with kinetic energy recovery systems, or KERS, which are designed to recuperate a vehicle's braking energy and use it during acceleration. Other top teams, including McLaren, Ferrari and Renault, have used KERS technology in various races since the Fédération Internationale de l'Automobile (FIA) legalized it in 2009.
"The advantage of the electric vehicle [EV] platform is it collects that wasted kinetic energy on a turn. I can convert that into electrons, and I can put that right back into my battery for it to be used by the electric motor later. It's like I'm cheating physics a little bit," said John Waters, an energy consultant and EV pioneer who helped develop General Motors Co.'s first electric car, the EV1, in the 1990s.

"In a Formula One car, all of that energy just goes to the brakes," he added. "Those brakes literally turn red-hot, and all of that energy turns to heat."
