Background
Work on Jaguar's new advanced saloon had been interrupted by the war, and it was not until 1950 that the design saw the light of day as the Mark VII.
A considerable improvement on what had gone before, the cruciform-braced chassis featured torsion-bar independent front suspension and all-round hydraulic brakes.
The 3.4-litre six-cylinder XK engine had already demonstrated its prowess in the XK120 sports car and proved capable of propelling the Mark VII's not inconsiderable bulk past 100mph.
Developed and refined through Marks VIIM and VIII, the last word in Jaguar's large, separate-chassis saloons - the Mark IX - appeared in 1958, by which time the 220bhp version of the 3.8-litre XK six was standard equipment together with power-assisted steering and all-disc braking.
A choice of manual or automatic transmissions was offered, the latter option being by far the most popular.
Motor magazine wound its test Mark IX up to 114mph and was equally impressed by the performance of the car's disc brakes. 'Should the driver wish to pass any other road user travelling at 100mph he can do so with a margin of some 15mph and should he wish to get down from 100mph to 30mph he can do so infallibly within 15 car lengths on a dry road.'
The Mark IX was produced by Jaguar Cars between 1958 and 1961. It was the last of Jaguar’s separate-chassis cars and was replaced by the altogether more modern-looking Mark X in 1961.
The Mark IX might have looked a lot like the Mark VIII, but performance, refinement and equipment were significantly improved across the board.
MK IXs found favour with heads of state around the world, including Charles de Gaulle, a man rarely accused of being overly Anglophilic in his allegiances.
The Nigerian government liked them so much they bought 40 and had them painted in the national colours of green and white.
