Although bearing a family resemblance to the XK120 and XK140, the XK150 was radically revised. A one-piece windscreen replaced the split screen, and the wing line no longer dropped so deeply at the doors. The widened bonnet opened down to the wings, and on the Roadster the windscreen frame was moved back 4 inches (102 mm) to make the bonnet longer. The car was available at various times in Red, Pearl Grey, White, Indigo Blue, Claret, Cotswold Blue, Black, Mist Grey, Sherwood Green, Carmen Red, British Racing Green, Cornish Grey, and Imperial Maroon. The big step forward for the 150 was the adoption of disc brakes, which Jaguar had developed with Dunlop and used very effectively on the later C and D-types.
This feature gave the 150 technical credibility and, apart from the very low-volume Jensen, a feature the competition lacked. A new B-type cylinder head increased power, which had progressed from the 120’s 180bhp to the 140’s 190bhp, to 210bhp.
Visually, the 150 was far more changed than the 140 had been over the 120. The old two-piece flat windscreen was looking very dated now and it was replaced by a wraparound one-piece item. The dramatic fall and rise of the wing line was considerably straightened and the cabin widened. This was achieved by putting the doors on a diet; the slimmer versions benefited the interior space considerably.
For many, this extra practicality makes the XK150 the most sought after of the three XK models. Driving it is still a vintage experience though; an E-Type feels far more modern in comparison for example. But the XK150 isn’t slow. It’ll keep up with modern traffic easily enough, but what really impresses is the XK engine’s flexibility as it’ll go from a standing start to 100mph in 36.4 seconds – using only top gear throughout. For a car launched in 1957, that’s pretty damned good.
This example is the very pretty Roadster version and is in exemplary condition throughout, probably one of the finest on the market today. Presented in black with matching hood and with immaculate red leather, this car has recently undergone a restoration of 2500 hours labour to bring it up to the fabulous and excellent condition you see today.
These Roadsters are iconic in their design and are one of the most beautiful of all Jaguars built and comes with a Jaguar Heritage Certificate.
