The Jaguar XK 140 is a sports car manufactured by Jaguar between 1954 and 1957 as the successor to the XK 120. Upgrades included more interior space, improved brakes, rack and pinion steering, increased suspension travel, and telescopic shock absorbers.
The XK 140 was introduced in late 1954 and sold as a 1955 model. Exterior changes that distinguished it from the XK 120 included more substantial front and rear bumpers with overriders, and flashing turn signals (operated by a switch on the dash) above the front bumper.
