Jaguar’s XK 120 stole the show at the October 1948 International Motor Exhibition at London’s Earl’s Court. It literally redefined the term “British sports car,” transforming the image from an angular, open-fendered car to a smooth envelope, streamlined and slinky. Customers and the motoring press gave it a warm welcome, validating Jaguar chief William Lyons’ decision to start production the following July.

The modern looks of the XK 120 were matched by the engineering under its skin. A sturdy box-section chassis featured torsion bar independent front suspension, and the live rear axle rode on long semi-elliptic leaf springs. Brakes were Lockheed hydraulic drum units, with twin leading shoes and a generous 12-inch diameter.

Heart and soul of the new car was a 3,442-cc dual-overhead-cam six. It had begun life as a two-liter four-cylinder design. Engineer Harry Weslake had experimented with a number of advanced concepts, of which a four-cylinder unit, with hemispherical combustion chambers and large main bearings, was the most promising. Lyons then directed him to add two more cylinders. Low-end torque was a bit disappointing, so the stroke was lengthened, resulting in the 3.4-liter final displacement.

In 1954, the improved XK 140 offered improved cooling, braking and precise rack-and-pinion steering, as well as greater passenger comfort and legroom, while retaining the 102-inch wheelbase and essential styling of its predecessor. During a brief three-year run, approximately 9,000 XK 140s were manufactured.

For those wanting more performance and style, the rare “MC” or “Special Equipment” option was available for only an additional $295. This version featured the C-Type big-valve cylinder head which brought the horsepower up to 210. Recently, the car received a nut and bolt restoration to the highest of standards. As one would expect, this car has the famous 3.4-liter six-cylinder engine matched with a four-speed manual transmission. It is finished in red with a black top and side curtains; and a tan leather interior. Completing the period look are chrome knock-off wheels wrapped in wide whitewall tires. Adding to the authenticity is the tool roll, spare tire, and the important JDHT certificate.

This stunning Jaguar was restored to JCNA standards and shows to be in absolutely stunning condition. Since the recent restoration, only test miles have been put on the car. This undoubtedly is one of the best XK 140 roadsters available.
