Between 1998 and 2011 McLaren built both the McLaren Technology Centre, a new headquarters and factory for the Group, and the McLaren Production Centre, in Woking. In December 2014, founder, CEO, Chairman, Director and McLaren shareholder Ron Dennis attempted to purchase 50% of McLaren Technology Group from Hamad bin Isa Al Khalifa and Mansour Ojjeh, after shareholder relations worsened, but the investment deals Dennis had arranged failed to materialise and the shareholding structure remained as before. Dennis tried to purchase the company again in October 2016, with an estimated bid of £1.7bn, but Ojjeh and Mumtalakat wanted Dennis out, refusing his bid and consequently placing him on garden leave. Dennis left the company upon the expiry of his contract in January 2017. In late May 2020, McLaren Group announced the layoff of 25% of its workforce as part of a company restructure due to the Covid-19 pandemic. McLaren originally entered Formula One in 1966 under its founder Bruce McLaren. However, in 1970 he died in a crash. The team was saved by Teddy Mayer who helped the team win their first Constructors' and Drivers title. After Teddy Mayer, Ron Dennis took over the McLaren Racing team and he has worked for the company ever since. However, at the beginning of the 2009 season, Ron Dennis handed over the F1 department to Martin Whitmarsh so Dennis could focus on expanding McLaren overall, and especially in the road car market  In 1966, McLaren suffered with reliability with their Ford 4.2-litre engine, and only scored a point after changing to a Serenissima V8. In 1967 they tried two different BRM engines. For the 1968 season they switched to Cosworth Ford engines. These continued to 1983, apart from a couple of Alfa Romeo examples, and then the TAG-Porsche turbo came in. This was the start of the MP4 cars, and the first entire carbon-composite chassis. Honda engines took over in 1988, and then in 1993 the MP4/8 had a Ford HB engine. The next year was a Peugeot V10, and then the Mercedes era began in 1995, ending after the 2014 season. The team's first F1 race win occurred in 1968 when Bruce McLaren won the non-championship Race of Champions at Brands Hatch driving a McLaren M7A Ford. Later that year the team scored its first Grand Prix win when Bruce McLaren took the Belgian Grand Prix at Spa Francorchamps.
