Jaguar XK150 Roadster

The final iteration of Jaguar’s XK120, the XK150 featured higher front fenders, a wider grille, a curved one-piece windshield, and perhaps most significant, Dunlop disc brakes at all four wheels. Jaguars not only went fast, but stopped that way too! The low door lines of the XK120 and 140 were discarded while the basic XK chassis remained albeit with an upgraded 3.4-liter twin-cam six as optional equipment. Although the previous body panel tooling was retained, only the boot lid was shared with the previous XK140. Inside all models received a padded dash top, softer and wider seats, and a windscreen that wrapped around the cockpit, American-style.

Initially offered in fixed head and drophead coupe versions, a roadster arrived 10 months later in March 1958. The car was a very capable performer, offering a zero-to-sixty dash in 8.5 seconds with a top speed of 123 mph. Roughly 75% of all XK150s were exported, proving the ever-increasing importance of the U.S. and other markets to Jaguar. It left production in 1961 to make way for the all-new E-type, still another iconic motor car from Jaguar Motors.

This car was auctioned off by RM Auctions in August 2009 at the Portola Hotel & Spa and Monterey Conference Center, Monterey, California.

190 hp, 3,442 cc twin overhead cam inline six-cylinder engine, four-speed manual transmission, independent wishbone front suspension with torsion bars and anti-roll bar, rear live axle with semi-elliptic springs, rack and pinion steering, Dunlop discs front and rear with servo. Wheelbase: 102".
