Gibson and Mason founded the Zytek Group in 1981 with two primary divisions: Zytek Automotive, based at Fradley, Staffordshire, focused on electrified powertrains; and Zytek Engineering, based at Repton, Derbyshire, handling motorsport and specialist vehicle development.
In 2000, Motorola acquired a 19 per cent stake in Zytek Automotive. In 2006, Continental AG, the German engineering conglomerate, purchased all of Motorola's automotive divisions and began increasing its holding in Zytek Automotive. By 2014, Continental AG had acquired the entire Zytek Automotive business, which continues to operate as a specialist powertrain and vehicle engineering enterprise developing electric motors for cars and commercial vehicles.
Zytek Engineering — the motorsport arm — remained under Bill Gibson's leadership and was formally renamed Gibson Technology on 1 October 2014.
Zytek Motorsport was the brand name applied to the group's motorsport product range. In 1987, Zytek acquired the British Alan Smith Racing outfit to expand its motorsport involvement, initially supporting the Jordan Grand Prix team in Formula 3000 before concentrating on engine development.
Zytek returned to direct team competition in 2004, entering the Le Mans Endurance Series with its Zytek 04S sports car, a chassis built on assets acquired from the defunct Reynard Motorsport in 2002. The 04S finished second in the team championship in 2005 on the strength of two overall race victories. Further chassis development followed, with the 06S for revised 2006 regulations and the entirely new Zytek 07S built for 2007, competing in both LMP1 and LMP2 classes of the Le Mans Series.
The GZ09S proved immediately successful in 2009, taking the LMP2 Le Mans Series Team Championship with the Quifel-ASM team and the Driver's Championship with Miguel Amaral and Olivier Pla. The Z11SN went on to win the LMP2 category at the 24 Hours of Le Mans in both 2011 and 2014, with Greaves Motorsport and Team Jota respectively, as well as the Le Mans Series LMP2 title in 2011.
In 2009, Zytek Engineering became the first manufacturer to score a podium finish with a hybrid LMP car. The vehicle, run by Corsa Motorsports, incorporated the Zytek Q10 Hybrid — a non-invasive parallel hybrid system consisting of a motor-generator, battery, and inverter designed to recover energy under deceleration and deploy it during acceleration. The car finished on the podium on its debut at Lime Rock Park.
In 2017, rebranded as Gibson Technology, the company became the exclusive supplier of the GK428 engine to the LMP2 class across the FIA World Endurance Championship, European Le Mans Series, and WeatherTech SportsCar Championship. The GK428 is a 4.2-litre naturally aspirated V8 producing approximately 600 hp, designed to be a single-supplier specification powerplant fitted to all LMP2 chassis including the Oreca 07, Ligier JS P217, Dallara P217, and Riley Mk. 30.
The single-engine-tender arrangement was intended to reduce costs for LMP2 teams while standardizing performance across the class. In its debut season, two GK428-powered LMP2 cars finished on the overall podium at the 24 Hours of Le Mans, with one leading the race overall for a significant period before the recovering factory Porsche LMP1 hybrid reclaimed the lead.
In 2018, Gibson developed the GL458, a 4.5-litre naturally aspirated V8 for LMP1 privateer competition, installed in the Rebellion R13 campaigned by Rebellion Racing and the BR Engineering BR1 run by DragonSpeed. The engine brought Rebellion's pair of R13s to a 3–4 finish at the 2018 24 Hours of Le Mans — a 1–2 result among privateer entries — behind the Toyota TS050 Hybrids. In February 2019, ByKolles Racing announced a switch to the GL458 for their CLM P1/01, replacing the Nissan Nismo VRX30A twin-turbocharged V6.
Gibson Technology was awarded the exclusive engine tender for the 2028 LMP2 regulations, extending the company's foundational role in sports prototype racing into the next regulatory era. Gordon Murray Design and Zytek Automotive collaborated on the T.27, an all-electric three-seater city car developed with a £4.5 million government-backed investment through the Technology Strategy Board.
