The Jaguar XK140 is a sports car manufactured and sold by Jaguar between 1955 and 1957 as the successor to the XK120. Upgrades included more interior space, improved brakes, rack and pinion steering, increased suspension travel, and telescopic shock absorbers instead of the older lever arm design. The XK140 was powered by the 3.4 litre Jaguar XK double overhead camshaft inline-6 engine. It was available as a Roadster (designated OTS - Open Two Seater - in America), Drophead Coupé (DHC), and Fixed Head Coupé (FHC). It was replaced by the Jaguar XK150 in 1957.
