Jaguar XK150 Roadster

Introduced in the fall of 1957, Jaguar’s XK150 built on the brilliant heritage of its XK120 and XK140 predecessors and was intended to directly compete with the likes of the BMW 507 and Mercedes-Benz 300SL. As the third and final evolution of its series, the XK150 was the best and most highly developed variant. Although similar in overall design to its predecessors, stylistic revisions included the replacement of the traditional cut-down doors with a higher and more subtly defined beltline. The front-end retained a traditional overall feel but now featured a widened grille shell and a curved, one-piece windscreen.

Performance continually increased throughout XK production, a result of careful development and the lessons learned on the racetrack. Race-bred four-wheel disc brakes were introduced with the arrival of the XK150 and provided stopping power to match the car’s performance levels and timeless good looks. In fact, the XK150 was the world’s first series-production car ever to feature power-assisted disc brakes at all four corners.

While the 3.4-liter “six” continued through to the end of XK150 production, the enlarged 3.8-liter version, first used in the Mark IX Sedan, became available for 1960. With a heady 220 bhp available in standard tune with twin carburetors and an optional 265-bhp version, the XK150 continued to provide the power, performance and excellent driving dynamics Jaguar enthusiasts had come to expect.

This car was auctioned off by RM Auctions in August of 2011 at the Portola Hotel & Spa and Monterey Conference Center, Monterey, California and in October of 2011 at the Battersea Evolution, London.
