The XK120 was launched in roadstar 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 Jaguar founder and design boss 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.
It was available in two open versions, first as the roadster (designated OTS, for open two-seater, in America), then also as a drophead coupé (DHC) from 1953; and also as a closed, or "fixed-head" coupé (FHC) from 1951. The DHC was a more deluxe open model, with wind-up windows, and wood-veneer dashboard and interior door caps, as on the FHC.
The roadster was successful in racing.
