In 1954 Jaguar introduced the XK140 as a replacement for the highly successful Jaguar XK120 that had first appeared in 1948. The XK Series was conceived by William Lyons as a sleek automobile that sat atop a short wheelbase in two-seat roadster configuration powered by a twin-cam engine. The XK120, named because of its 120 mph top speed, was powered by an engine that produced 160 horsepower. The 'X' represented the 'experimental' engine type while the letter 'K' was the sequence. The XK140 received a larger 190 horsepower engine, rack-and-pinion steering, and more interior space. Interior space was gained by the repositioning of the engine and firewall, thus keeping the dimensions of the chassis identical to the XK120. Minor improvements were done to the aesthetics of the vehicle. A Special Equipment package was available that included Dayton wire wheels and a 210 horsepower engine, the result of C-Type heads and dual exhaust.
The XK legacy continued with outright victories at LeMans in 1953, 1955, 1956 and 1957. This 24 hour grueling marathon is a true test of speed and endurance. The XK-Series proved to be the best.
Production continued through 1957 when it was replaced by the XK150. The XK140 carried on the success started by the XK120. The OTS version proved again to be the most popular with sales for the DHC and Fixed versions still respectable. In Jaguar lingo, 'OTS' refers to 'open two-seater' or 'roadster' while 'DHC' represents 'drophead coupe'. The roadster versions often featured removable side curtains instead of windows. The top could be folded behind the seats and conveniently hidden by the rear shroud. The DHC body has roll-up windows, wood interior, and an attached top that, when folded, would stick-up above the body.
