The final iteration of the XK sports car line and the last Jaguar to carry a separate chassis, the XK150 was introduced in May, 1957.

While its use of independent torsion-bar front suspension, a 'live' leaf-sprung rear axle and rack-and-pinion steering mirrored the practice of its XK140 predecessor, the new model benefitted from the option of all-round Dunlop disc brakes (though, in practice very few – if any – cars were delivered with drum brakes).

Stylistically, the newcomer was brought up-to-date with more subdued curves and a larger, wrap-around single piece windscreen.

With the E-type still very much under development, Jaguar was keen to sustain the sporting reputation that a remarkable five Le Mans victories (1951, 1953, 1955, 1956 and 1957) had earned it.

Initially powered by a 3,442cc derivative of the marque's race-proven DOHC straight-six engine, the XK150 could be specified with an enlarged 3,781cc unit from late 1959 onwards.
