The XK150 was available at first only in fixed and drophead coupé forms; the open roadster version didn’t appear until the following year. 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, the latter delivering an astonishing 0-60mph time of 7.3 seconds and a top speed of 136mph.
This was achieved by the introduction of the Weslake-developed ‘straight-port’ cylinder head, high-compression pistons, triple 2” SU carburetors and twin electric fuel pumps. The car regularly recorded in excess of 130mph in magazine road tests. ‘The Jaguar XK150 is undeniably one of the world’s fastest and safest cars. It is quiet and exceptionally refined mechanically, docile and comfortable… we do not know of any more outstanding example of value for money,’ declared The Autocar.
Supplied new in 1958, the wonderful matching numbers XK150 S Open Topped Sports version on offer today has enjoyed a detailed restoration in 2008, which included a repaint and replacement convertible hood.
The 3.4 litre triple carburettor engine is said to run smoothly, and the gearbox is a pleasure to use. Pleasingly the XK has been fitted with the respected EZ power-steering upgrade, also a Kenlowe Fan for better cooling. As a result we are told this beautiful Jaguar is great to drive and looks stunning.
Finished in Old English White with a contrasting red leather interior, and supplied with the relevant Heritage Trust certificate and title document, this is a wonderful example of one of the most enduring post-war sportscars ever produced.
