The Jaguar XK120 was a sports car manufactured by Jaguar between 1948 and 1954. Jaguar's first post-war sports car, it succeeded the SS 100, which ceased production in 1940.
The XK120 was launched in roadster form at the 1948 London Motor Show as a testbed and show car for the new Jaguar XK engine. It caused a sensation, which persuaded William Lyons to put it into production.
The "120" in its name referred to its 120 mph (193 km/h) top speed (faster with the windscreen removed), which made the XK120 the world's fastest standard production car at the time of its launch.[3].
It was available in two convertible versions — first as the roadster (designated OTS, for open two-seater, in America), then also as a drophead coupé, or DHC, from 1953 — and as a closed, or "fixed-head" coupé (FHC) from 1951.
The roadster version was popular with Hollywood stars such as Humphrey Bogart, Ingrid Bergman, Clark Gable and Lauren Bacall.[citation needed]
