Porsche 911 GT3 R Hybrid

Trickle, trickle, racing star
It's called the trickle-down effect, where cutting-edge technologies forged in the crucible of Formula One end up in less esoteric cars. Last season's big hardware story was KERS, the kinetic energy recovery system that stores braking energy in a battery then gives a 10-hp jolt on the straightaway. It wasn't a generic third-party setup; each participating team produced its own system. And naturally, those systems were far more involved and advanced than anything found in a Prius.
A Williams F1 KERS can now be found in the 2010 Porsche 911 GT3 R Hybrid. The car's conventional drivetrain is a naturally aspirated four-liter flat six that makes a mighty 480 hp and drives the rear wheels. The front axle, however, has a couple of 60 kW electric motors to provide some extra oomph.

The irony is that most F1 teams, frustrated by reliability issues, ditched KERS by the end of last season and it won't be making a return for 2010. Our hope is that this won't be some empty gesture to appease the greenies. The car will be racing this May at the 24-hour Nürburgring bash, where Porsche says the focus is not on winning the race but on using the car as a "racing lab." It could make up time by needing fewer pit stops, which it will need to catch Walter Röhrl, who'll reportedly be driving a stock GT3 RS against the field.
