While Porsche’s new 918 Spyder hybrid concept is little more than a show-piece, the German automaker also used the Geneva Auto Show to officially debut the 911 GT3 R Hybrid race car. Set to compete on the track in the near future, it is based on the GT3 chassis and is powered by a traditional 4.0-liter flat-six engine making 480-hp at the rear wheels. In addition, two electric motors will be used to power the front wheels, with 60 kW of power going to each axle. The driver will be able to call up this extra power on-demand, giving the GT3 R a temporary all-wheel drive setup as well. The power surge is expected to last between 6 and 8 seconds.
Power for the electric motors comes via a flywheel generator that operates as a regenerative braking system, powering-up the on-board battery under braking.
Porsche will compete with the GT3 R Hybrid at the 24 Hours of the Nürburgring race, which runs from May 15th to 16th.
