Jaguar Cars Ltd., better known simply as Jaguar, is a British luxury car manufacturer, headquartered in Coventry, England. It is a wholly owned subsidiary of the Indian company Tata Motors Ltd. and is operated as part of the Jaguar Land Rover business. Jaguar was founded as the Swallow Sidecar Company by Sir William Lyons in 1922, originally making motorcycle sidecars before evolving into passenger cars. The name was changed to Jaguar after World War II due to 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 and became a constituent of the FTSE 100 Index until it was acquired by Ford in 1989. Jaguar also holds Royal Warrants from HM Queen Elizabeth II and HRH Prince Charles. Jaguar cars today are designed in Jaguar/Land Rover's engineering centres at the Whitley plant in Coventry and at Gaydon in Warwickshire, and are manufactured in two of Jaguar/Land Rover's plants; Castle Bromwich assembly plant in Birmingham and Halewood Body & Assembly near Liverpool.
