The Jaguar XK140 was a sports car manufacture by Jaguar between 1954 and 1957. Upgrades over its predecessor, the XK120, included better brakes, rack and pinion steering, and modern tube type shock absorbers instead of the older lever arm design. The name referred to its 140 mph (225 km/h) top speed. The XK140 continued to feature the famous Jaguar XK engine with the SE mods from the XK120 as standard, now delivering 190 bhp (142 kW) at 5750 rpm. The special C-Type cylinder head was also carried through from the XK120 catalogue as an option, providing 210 bhp (157 kW).
