The Jaguar XK120 is a sports car manufactured by Jaguar between 1948 and 1954. It was Jaguar's first sports car since SS 100 production ended in 1939. The XK120 was launched in open two-seater or (US) roadster form at the 1948 London Motor Show as a testbed and show car for the new Jaguar XK engine designed by Jaguar Chief Engineer William Heynes. The sports car caused a sensation, which persuaded Jaguar founder and Chairman William Lyons to put it into production.
The fastest production car in the world in its time, it would go on to be developed into the XK140 and XK150 models.
