In 1954 Jaguar replaced their seminal XK120 with the slightly upgraded XK140. It used the same basic architecture as the preceding model but featured several interior and body upgrades including full-width bumpers, increased interior space and rack & pinion steering. As before, it was offered as an Open Two Seater roadster, Drophead Coupe convertible or Hardtop Coupe.

Fresh from their victories at the 24 Hours of Le Mans, Jaguar used their competition pedigree to sell the XK140. The principle brochure said “All the accumulated wealth of knowledge and experience gained in the hard school of racing have been built into the new XK140 models which are powered by the famous 3½ litre twin overhead camshaft XK engine.”
