Porsche to Show Off a Hybrid 911 GT3 R in Geneva
By Chris Weiss
Rolling out of Stuttgart for a Geneva appearance, the new 911 GT3 R Hybrid will feature a powertrain that combines two 60 kW electric motors and a rear-mounted 480 hp 4.0-liter six-cylinder engine. The motors will be mounted to the front axle and, rather than batteries, the racer will use a flywheel generator to deliver power to the motors. The generator spins at up to 40,000 rpm and sends bursts of energy to the motors when it’s needed. It is charged when the driver applies the brakes; the motors reverse the chain and send power to the generator.
The hybrid technology is used to provide the driver with short six- to eight-second bursts of power e.g. when accelerating to overtake another car. The set-up also functions to save fuel.
After Geneva, the GT3 R Hybrid will undergo testing at Nürburgring to provide insight on the application of hybrid technology. [via WCF]
