Jaguar XJS

The Jaguar XJ-S (later called XJS) is a luxury grand tourer manufactured and marketed by British car manufacturer Jaguar Cars from 1975 to 1996, in coupé, fixed-profile and full convertible bodystyles. There were three distinct iterations, with a total production of 115,413 units over 20 years and 7 months. Originally developed by Chief Engineer William Heynes using the platform of the then-current XJ saloon, the XJ-S was noted for its prominent rear buttresses. The early styling was partially by Jaguar's aerodynamicist Malcolm Sayer—one of the first designers to apply advanced aerodynamic principles to cars; however, Sayer died in 1970, before the design was finalised. Its final iteration, produced from 1991 to 1996, was manufactured after Jaguar was acquired by Ford, who introduced numerous modifications – and eliminated the hyphen in the name, marketing Jaguar's longest-running model simply as the XJS.
