Geneva 2011: Porsche 918 RSR 204 additional stores in the flywheel-hp

Following its world premiere in Detroit in January is the Porsche 918 RSR at the Geneva Motor Show (1st-03.13.2011) its European debut. The concept study of a super sports car with hybrid technology has monocoque carbon fiber reinforced plastic (CFRP) and a flywheel, which supplies if necessary, additional operating power of the V8 engine is a development of the direct-injection engine from the successful RS Spyder racing car and make the 918 RSR 563 hp at 10 300 revolutions per minute.

The electric motors on the two front wheels, each controlling 75 kW for a total of 150 kW / 204 hp, at the peak input power of 767 hp. This attempt at additional braking power is conserved in a flywheel storage, the rotor revolves at up to 36 000 revolutions per minute. The charge which reversed during braking when the two electric motors at the front and work their function as generators.

The driver can push the retrieve and use stored energy during acceleration or overtaking. Here, the flywheel is decelerated electromagnetic, deliver up to 204 hp in addition to the two electric motors on the front axle. This additional service is at full charge around eight seconds. (Ampnet / jri)
