Jaguar Cars Ltd known simply as Jaguar is a British luxury and sports car manufacturer, headquartered in Whitley, Coventry, England. It is part of the Jaguar Land Rover business,a subsidiary of the Indian company Tata Motors.Jaguar was founded as the Swallow Sidecar Company by Sir William Lyons in 1922, originally making motorcycle sidecars before developing passenger cars. The name was changed to Jaguar after WWII to avoid the unfavourable connotations of the SS initials.Following a merger with the British Motor Corporation in 1968, subsequently subsumed by Leyland, which itself was later nationalised as British Leyland, Jaguar was listed on the London Stock Exchange in 1984, and became a constituent of the FTSE 100 Index until it was acquired by Ford in 1990. Jaguar has, in recent years, manufactured cars for the Prime Minister, the most recent delivery being a XJ model on 11 May 2010. The company also holds royal warrants from HM Queen Elizabeth IIand HRH Prince Charles.Jaguar cars today are designed in Jaguar Land Rover's engineering centres at the Whitley plant in Coventry and at their Gaydon site in Warwickshire, and are manufactured in Jaguar's Castle Bromwich assembly plant near Birmingham.
