===Williams Hybrid Power===
Williams Hybrid Power (WHP) was the division of Williams F1 that developed electromechanical [[flywheel]]s for mobile applications such as buses, trams and high-performance endurance-racing cars. A hybrid system that uses a spinning composite rotor to store energy, these flywheels help a vehicle save fuel and ultimately reduce its CO<sub>2</sub> emissions.

WHP was first established in 2008 and immediately set about developing a new flywheel energy-recovery system for the Williams F1 Team after the introduction of Kinetic Energy Recovery Systems (KERS) into Formula One for the 2009 season. While other teams were pouring their efforts into electric battery systems, Williams F1 opted to go down the flywheel route because of a strong belief in the technology's wider applications. While it was never raced in Formula One due to technical changes, WHP has since seen its technology adapted for a range of applications. For example, the Audi R18 hybrid car that won the 2012 Le Mans 24 Hours used a WHP flywheel. WHP has also seen its flywheel technology introduced into a series of buses as part of a deal with the Go-Ahead Group, one of the UK's biggest transport operators. In April 2014, Williams Hybrid Power was sold to [[GKN]].<ref>{{cite web |url=http://williamsf1.com/Investors/Investors-News/GKN-Acquires-Williams-Hybrid-Power/ |archive-url=https://web.archive.org/web/20140410045310/http://williamsf1.com/Investors/Investors-News/GKN-Acquires-Williams-Hybrid-Power/ |archive-date=10 April 2014 |title=GKN Acquires Williams Hybrid Power |publisher=Williams F1 |date=1 April 2014 |access-date=2 January 2015}}</ref>
