1962, Coventry Climax chairman, Leonard Pelham Lee announced the withdrawal from building Formula 1 engines, stating that the company was losing money and not gaining enough publicity from their involvement. Nonetheless, Coventry Climax remained in Formula One until they were unable to come up with a new engine for the three-litre formula. The company was purchased by Jaguar Cars in 1963, which itself merged with the British Motor Corporation (BMC) in 1966 to form British Motor Holdings (BMH). In May 1964, the Royal Automobile Club presented the Dewar Trophy, which is given at the recommendation of RAC's Technical and Engineering Committee for the most outstanding British achievement in the automotive field, to Leonard Pelham Lee.

In the early 1970s, the fire pump business was sold back into private ownership, and the Godiva Fire Pumps company was formed in Warwick. In 1977 Coventry Climax acquired the Warrington forklift truck business of Rubery Owen Conveyancer, renaming it Climax Conveyancer. In 1982 BL sold off the Coventry Climax forklift truck business back into private ownership to Coventry Climax Holdings Limited. Sir Emmanuel Kaye, also chairman and a major shareholder of Lansing Bagnall at the time, formed the company, independent of his other interests for the purpose of acquiring Coventry Climax. In 1986 Coventry Climax went into receivership and was acquired by Cronin Tubular. In 1990, a further change of ownership came with the engine business being sold to Horstman Defence Systems of Bath, Somerset, thus breaking the
