Former Subsidiaries Williams Advanced Engineering Williams Advanced Engineering (WAE) is the technology and engineering services business of the Williams Group. Based in the United Kingdom, it is located in a dedicated facility of , adjacent to Williams Formula One facilities. The company provides the battery technology used in Formula E and Extreme E, and has assisted the development of the electric Vanda Dendrobium car from Singapore. It has worked with Jaguar to create the C-X75 hybrid supercar. WAE partnered once again with Jaguar to build new stunt C-X75s for the 24th James Bond film, Spectre. WAE announced in June 2013 a new collaboration with Nismo, the performance-orientated brand of Nissan, to partner in the development of high-performance road cars. The company announced in August 2017 a collaboration with Singer Vehicle Design. The initial work is a modified, naturally aspirated, air-cooled, flat-six Porsche 911 engine with a 4.0L capacity, four valves per cylinder and four camshafts, rated at 500HP. On 1 May 2019, Williams Advanced Engineering announced their partnership with the FIA sanctioned electric off-road racing series, Extreme E.

WAE generated revenues of £10.9m in fiscal year 2014–15, with profits of £1m. Williams Hybrid Power Williams Hybrid Power (WHP) was the division of Williams F1 that developed electromechanical flywheels 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 CO2 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
