During the 50's and 60's Jaguar began producing series of successful sports car. Known for their high performance, conspicuous look, and success on the racetrack winning the Le Mans 24-hour race on several occasions. Jaguars success came with the progress of their twin-cam straight six-cylinder engine, despite low octane rating. During the 50's vehicles were offered with three different piston configurations that altered the octane level of the engine from low, medium, and high. Jaguar facing financial struggles and an uncertainty of the future, Lyons sold the company to British Motor Corporation and formed British Motor Holdings limited. After little attention was given to Jaguar, and very limited capital to aid in development of Jaguar products the company was again sold during the Thatcher administration of to a private company in 1984. During the 1980's Jaguar made significant strides in terms of engineering and production that had previously prevented them from selling more cars. Sir John Egan helped develop overall quality, increase production rates, increase delivery efficiency, and cut overall company costs. Jaguar began to catch the public's eye again with more moderate pricing across the board and an overall increase in performance.
During the 1990's Ford Motor Company purchased Jaguar, making Jaguar a part of its new Premier Automotive Group alongside Range Rover, Aston Martin, Volvo, and Lincoln. During this time Jaguar was never able to regain sales and popularity, never recording a profit while being owned by Ford. Jaguar was sold to Tata Motor Limited in 2008, since the company has worked on rebuilding the Jaguar brand and continuing the legacy of high-performance sports vehicles.
