Williams Hybrid Power flywheel proves powerful and reliable in Porsche 911 GT3 R Hybrid in Zhuhai race

The Porsche 911 GT3 R Hybrid completed the recent 1,000 km of Zhuhai in China ahead of all other GT cars and with fewer stops for gasoline. At the core of the hybrid system is Williams Hybrid Power’s (WHP) flywheel energy storage unit. (Earlier post.)

WHP’s patented Magnetically Loaded Composite (MLC) flywheel technology, originally developed for Formula One, captures and stores a vehicle’s kinetic energy in a high-momentum composite flywheel. This energy, otherwise lost as heat during braking, can be re-introduced into the driveline to save fuel, or bolster performance, both crucial parameters in endurance racing also having clear applicability to road car application.

Zhuhai marked the last of three endurance races for the Porsche Hybrid in 2010. Throughout the season the MLC flywheel technology has operated without fault in a deep-cycling, high duty cycle and aggressive mobile environment, according to Williams F1.

As an example of WHP’s focus on wider applications for the MLC flywheel technology, it participates in a consortium with companies such as Jaguar Land Rover who are seeking to develop hybrid flywheel applications at sufficiently low cost to facilitate mass uptake in the road car market. The purpose of the project is to refine technologies that can bring considerable reduction in road car emissions.
