WHP’s electric flywheel was chosen by Porsche Motorsport as an alternative to a battery option for the energy storage medium on their 2010 911 GT3 R Hybrid endurance racing car. This car competed at several endurance races in 2010, including the 24 Hours Nürburgring race where it famously led before retiring within the last few hours due to an engine-related failure (a problem unrelated to the hybrid system). In 2011, the GT3 R secured its first victory in the VLN race at the Nordschleiefe making WHP’s flywheel a race-winning technology.
The Porsche Hybrid is considered to be the first of its kind. A hybrid racing car uncompromised on performance, and one that has shifted public perception on the efficacy of hybrid technology in racing with exciting possibilities for real world application in the future. Indeed Porsche has gone further down the road with its hybrid plans when it announced its latest version; the 918 RSR hybrid concept sportscar with electric flywheel energy storage, at the 2010 Detroit Motorshow.
