When Motor road tested a 3.4-litre XK150S FHC in August 1959 they recorded a best top speed of 133.9mph and their conclusion was that the “XK150S Jaguar is a truly remarkable car which combines a stupendous performance with surprising docility and good manners. To drive it is one of the more memorable experiences motoring has to offer.”

However, in later years it would seem that the XK150’s mixture of modern and old-fashioned style confused some enthusiasts, while the number of options that would eventually become available also muddied the water, providing something of an obstacle when considering the XK150’s overall role within the Jaguar XK’s sporting dynasty.

As such, while the XK150 was initially only available as a refined closed or open touring car, later it could also be had as a skin-of-your-teeth roadster – and the car’s outward dimensions changed depending upon which model the customer chose.

Indeed, for the XK150 roadster, Jaguar shifted the scuttle back by four inches (103mm) as compared to that fitted to the drophead coupé (DHC) and fixed-head coupé (FHC) models. As a result, the roadster has a longer bonnet and front guards.
