Background
The XK150, launched in 1957, benefitted from years of development from the previous two incarnations of the XK lineage. Whilst the styling had been developed from the initial XK120 design, it was given a more muscular purposeful look as well as some modern mechanical upgrades too such as disc brakes.
The engine choices were updated too with the 3.4 litre producing 210bhp and 250bhp on the ‘S’ model introduced in 1959, and a 3.8 litre engine, also introduced in ’59, producing 220bhp with the ‘S’ model giving a staggering quoted 265 bhp.
