Background
With styling very clearly influenced – some would say copied – from the equally gorgeous low-drag BMW 328 Coupe that competed during the 1940 Mille Miglia, the XK120 was Jaguar’s first new post-war sports car. Its introduction at the 1948 Earls Court Motor Show in London was almost accidental. The MkVII saloon had been delayed, but Jaguar boss William Lyons had an all-new high-performance motor ready to go. The answer was to rapidly develop a new sports car prototype, simply to display the XK engine.
The new motor caused almost as much of a stir as the striking XK120 prototype within which it was placed, as it brought 160bhp, twin-camshaft, six-cylinder performance to a motoring world still reeling from post-conflict austerity. Such was the interest for the sleek and fast (near 120mph) new Jaguar, the decision was made to put it into production. When it was launched, eight months later, the XK120 instantly outclassed almost every other machine on the road, and at just £1263, it perfectly piqued the interest of the vital US export market in the process.
Later XK140s and XK150s added more power, dimensions and luxury to the mix, but the formula still proved a winner, right up to the latter’s replacement by the E-type in 1961.
