In 1932, the UK overtook France to become Europe's largest car producer (a position which it retained until 1955). In 1937, the UK produced 379,310 passenger cars and 113,946 commercial vehicles. To celebrate the granting of his peerage, William Morris upon becoming Viscount Nuffield, reorganised his motor vehicle companies in 1938, which by then included not only Morris Motors and MG, but also Wolseley and Riley (bicycle company founded in Coventry in 1890 and making cars since 1913), into the Nuffield Organization. In 1939, the top producers were Morris: 27%, Austin: 24%, Ford: 15%, Standard (founded in Coventry in 1903): 13%, Rootes (which had acquired Humber and Sunbeam): 11%, Vauxhall (building cars since 1903, acquired by GM in 1925): 10%.
