GKN – Gyrodrive
The GKN Hybrid Power flywheel is an electric flywheel, storing energy mechanically in a high-speed carbon rotor. This novel technology cut its teeth in top-flight endurance racing, helping to power Audi’s R18 e-Tron Quattro to four successive Le Mans 24-hour race podiums. The APC ‘Gyrodrive’ project, which closed in September ’17, sought to develop and test this technology for use in the Hybrid bus market.
