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.
We’d like to think that, frankly, he gave a damn about being the first owner.
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.
The successor to the XK140, the XK150 was unveiled in 1957. The XK150 was available at first only in fixed and drophead coupé forms, with Jaguar offering a stripped-down roadster named the XK150 OTS (open two-seater) the following year.
As its nomenclature suggests, the XK150 was a progressive development of the XK120 and XK140, retaining the same basic chassis, 3.4-litre engine and four-speed Moss transmission of its predecessors while benefiting from a new, wider body that provided increased interior space and improved visibility courtesy of a single-piece wrap-around windscreen.
Cleverly, the new body used many XK120/140 pressings, the increased width being achieved by means of a 4"-wide central fillet. A higher front wing line and broader radiator grille were other obvious differences, but the new model's main talking point was its Dunlop disc brakes.
Fade following repeated stops from high speed had been an issue with the earlier, drum-braked cars, but now the XK had the stopping power to match its prodigious straight-line speed.
At 190bhp, the engine's maximum power output was identical to that of the XK140 so performance was little changed. 'Special Equipment' and 'S' versions came with 210 and 250bhp respectively. Overdrive and a Borg-Warner automatic gearbox were the transmission options, the latter becoming an increasingly popular choice, while a Thornton Powr-Lok limited-slip differential was also available.
Steel wheels remained the standard fitting, though XK150s so equipped are a great rarity, as most were sold in SE (Special Equipment) specification with centre-lock wire wheels.
The much-admired chromed Jaguar mascot was made available as an optional extra on an XK for the first time.
