Background
When the former Swallow Sidecar Company presented the Jaguar XK120 at the 1948 London Motor Show, it caused something of a stir.
Only presented as a show car for the brand-new XK engine, the response to the stunning looks of the XK120 convinced Sir William Lyons to put the vehicle into production, and it landed almost unchanged.
Based on the underpinnings of the Mark V, the first run of just over 240 cars sported an all-aluminium body over an ash frame, but such was demand – following a famous run at the Jabbeke motorway which saw a prototype example hit a world record 135mph – that later models switched to a heavier, pressed steel body.
Jaguar produced the bulk of the early cars as left-hand drive models, to suit demand from the USA – likely helped by the fact Gone With The Wind's Clark Gable was one of the very first owners in 1949 – and all in the initial roadster “OTS” (open two seater) body.
It proved to be an excellent race car too, winning circuit races, endurance events, and road rallies in the production car category. Famously, an XK120 won the first ever NASCAR Grand National road race, leading to foreign-brand cars being banned from the series.
A fixed-head coupe (FHC) arrived in 1951, adding some all-weather practicality to the otherwise rain-averse XK, but the car really hit its stride when the drop-head coupe (DHC) convertible landed in 1953. The insulated soft-top proved the best of both worlds.
With just over 12,000 cars produced, Jaguar retired the XK120 in 1954, replacing it with the upgraded XK140.
