Background
The XK120 was first shown to the world at the 1948 London Motor Show.
With a slim waist and alluringly voluptuous curves that would put Jessica Rabbit to shame, it caused weak men to faint and drove strong women to drink.
Once seen, the XK120 was forever coveted.
The ensuing tsunami of desire from a salivating public persuaded Jaguar founder and Chairman William Lyons to put it into production.
As demand grew, the aluminium XK120 was re-imagined in steel for a full production run. Fixed-head and drophead coupé models joined the line-up in 1952 and 1953 respectively.
When XK120 production finally ceased in 1954, a total of 12,064 XK120s been sold.
Very few of these cars ended up in the hands of UK buyers.
Most went to the US, where they secured Jaguar’s place in the hearts and minds of American enthusiasts for decades to come.
In 1949 the very first production car (chassis number 670003) was delivered to no less a luminary of the silver screen than Clark Gable.
The ‘120’ in the name referred to the aluminium car's 120 mph top speed, which made it the world's fastest production car at the time of its launch.
The car’s potential was proven in Jabbeke, Belgium, on 30th May 1949, when HKV 500 driven by Ron ‘Soapy’ Sutton achieved 132.6mph.
In 1953 a modified XK120 recorded a simply astonishing speed of 172mph at Jabbeke.
Newly introduced for 1955, the Jaguar XK140 was broadly similar to, though more refined than, its sensational XK120 predecessor, with major engineering changes being confined to the repositioning of the engine 3" further forward and the adoption of rack-and-pinion steering.
Now, 3” might not sound very much, but it made an extremely welcome world of difference to the taller driver, as your author can verify - having found himself unable to squeeze into a KX120 on several occasions.
The suspension and brakes remained much as before, though with stiffer torsion bars at the front and telescopic shock absorbers replacing lever type at the rear. Outwardly the newcomer was distinguishable by its revised radiator grille, rear lights incorporating flashing indicators, and larger bumpers. The power unit remained Jaguar's well-tried, 3.4-litre, twin-cam six. A close-ratio gearbox enabled better use to be made of the increased performance and overdrive became an option for the first time.
