[3] As of 2014[update], Pilbeam's company continued to produce hillclimb cars and sports prototype chassis for endurance racing.
[4] Pilbeam spent much of his early life in West London, and had little interest in competition cars until he attended the 1958 British Grand Prix, whilst at Bristol University.
The car, driven by Richard Attwood, was entered for the 1964 British Grand Prix at Brands Hatch but was withdrawn after practice.
[1][3][5] After the abandonment of the P67 project, Pilbeam worked on the BRM H16 engine, helping to develop it to the point where Jim Clark was able to win the 1966 United States Grand Prix with a Lotus 43-BRM.
[1] In this machine, during practice for the 1977 British Grand Prix at Silverstone, Purley was involved in one of the heaviest impacts where a driver has survived.
[5] In 1997 new premises at Bourne were opened by Bette Hill, (widow of Graham),[11] and Pilbeam continued to work within the industry on both road and racing car projects on a freelance basis.
