Mike Hewland, founder of the Hewland Engineering company that became synonymous with motorsport transmission technology, has died at the age of 89.
Formed in 1957, Hewland Engineering's first Formula 1 involvement was altering a gearbox for the British Racing Partnership team, before the company really made its name in Formula Junior.
From there, the Hewland business grew to such an extent that for much of the 1960s, 70s and 80s, almost the entire F1 field ran its gearboxes, with Ferrari the only exception for a long period. The package of a Cosworth DFV engine mated to a Hewland gearbox dominated most of the era.
Mike Hewland retired in 1991, with his son William taking over at the helm of Hewland Engineering.
