Jaguar XK140

The XK140 was introduced in 1954 and was a logical update on the XK120, utilising the same chassis but with a modified body. This created more room internally, and there was also more precise rack and pinion steering, better cooling, and bigger bumpers and stronger cast grille which were aimed mostly at the US market. The most radical change was to the fixed head coupe, which had the bulkhead moved 6” further forward, which, combined with a higher roofline, created a lot more space for driver and passenger, as well as incorporating two vestigial rear seats. There was also a new bigger radiator for more efficient cooling, and an overdrive option for improved driveability. C-Type head option gave welcome performance improvement. All three body styles available from the outset (October 1954).

Pros: Worthwhile mechanical and body improvements bring greater usability to the XK range. Added space particularly useful in drophead and fixedhead models.

Cons: Many feel that the heavier bumpers, cast grille, and added chrome a retrograde step aesthetically. Proportions of 140 fixedhead in particular lost the elegance of 120 predecessor.
