Production years: 1954 - 1957

The XK140 externally was identifiable by the more substantial bumper bars, cast radiator grille and internally by occasional rear seating and other trim changes. To provide more room inside, the engine was moved forward by 3 inches and for the first time an automatic transmission was available as an option. The XK140 was also produced in the same three styles as the XK120, Roadster, Drop Head Coupe and Fixed Head Coupe and remained in production until 1957.
