At 190bhp, the standard 3.4-liter engine’s maximum power output was identical to that of the XK140, so performance was little changed. Overdrive and a Borg-Warner automatic gearbox were the transmission options, the latter becoming an increasingly popular choice, while a Thornton Powr-Lok limited-slip differential was available for the XK150S.
Cleverly, the new body used many XK120/140 pressings, the increased width being achieved by means of a 4?-wide central fillet. A higher front wing line and broader radiator grille were other obvious differences, but the new model’s main talking point was its Dunlop disc brakes.
