The XK 150 was the first series-production car to employ four-wheel disc brakes as standard. Developed from the XK 120 and XK 140, it was heavier but offered greater comfort and interior space. A distinctly modernising feature was the wrap-round windscreen of toughened glass. This replaced the more basic divided screen of previous models.

Introduced in 1957 with a 3.4 litre engine, a faster 3.8 litre version was available from 1959. By the late 1950s the design was considered out of date. For a performance car, however, it still represented good value for money. By comparison, the Ferrari 250 GT cost £6,326 in 1960.
