1955 Jaguar XK-140

The Jaguar XK140 was launched in 1954 and was broadly similar to its XK120 predecessor, though more refined and sophisticated. The major engineering changes were confined to the adoption of rack-and-pinion steering as used on the racing C-Type, and repositioning the engine three-inches further forward. The brakes and suspension remained mostly unchanged, though with telescopic shock absorbers replacing the previous lever-type at the rear and stiffer torsion bars at the front. Like its forbearer, the Xk140 was constructed in three body styles consisting of a roadster, coupe, and drophead coupe, the latter two having increased cabin space and occasional rear seats. Exterior changes included a revised radiator grille, larger bumpers, and rear lights incorporating flashing indicators.

The engine bay continued to house the tried-and-true 3.4-liter, twin-cam six, which now delivered 190 horsepower in standard trim thanks to revised porting and higher-lift camshaft. Steel bearing caps replaced the previous cast-iron type, ensuring reliability. The increased performance was handled by a close-ratio gearbox while Laycock-de Normanville overdrive became an option for the first time.

Jaguar XK140 models with the Special Equipment (SE) package came with wire wheels and Lucas fog lamps and could be optioned with a 210 horsepower engine with 'C'-type cylinder head. The XK140 was capable of top speeds in excess of 120 mph. A USA-specification XK140 MC (as the 'C'-type head-equipped SE version was known there) was tested by Road & Track magazine with a zero-to-sixty mph time of 8.4 seconds and a top speed of 121.1 mph.

The Jaguar XK120 had made its debut in 1948 and produced through 1954 with approximately 12,000 examples made. It was at the forefront of sports car manufacturing, with graceful lines and race-proven performance capabilities. The arrival of the XK140 built upon its predecessors sound original design, bringing with it a comprehensive list of improvements designed to overcome its predecessor's few shortcomings while maintaining its appeal, especially in the all-important U.S. export market. It retained the basic 102-inch wheelbase length of its predecessor, ergonomics were significantly improved, and race-proven mechanical enhancements kept it at the forefront of performance. During its three-year production run, ending in 1957, just 8,943 examples were made. Of those, 1,392 were in right-hand-drive configuration while the remaining 7,545 were in left-hand drive. Clearly, the majority were intended for the North American market. Production between the three body styles was fairly similar, with the open two-seater being the most popular, with 3,349 examples built. The fixed-head and drop-head were nearly identical, with 2,790 of the drophead, just eight less than the fixed-head version. Of the 3,349 open two-seaters, just 73 were in right-hand drive configuration.

The Jaguar XK140 was superseded by the XK150.
