Mike Hewland (pictured above, centre), whose eponymous company was synonymous with motorsport transmission technology, has passed away at the age of 89, his family has confirmed.
Founded in 1957, his Hewland Engineering concern had its first F1 involvement when called upon to perform an emergency gearbox repair for the BRP team.
His first competitive appearances as a gearbox and transmission supplier came in Formula Junior, and the growth of the company was so rapid that it became a rarity for a Grand Prix team not to run his gearboxes for the next three decades, with a partnership with the Cosworth DFV engine forging a long-term marriage between the two quintessentially British firms.
He retired in 1991 and handed over the reins to his son William, who continues to head the firm today.
We extend our deepest condolences to the Hewland family.
