The XK150 had a strong resemblance to both the XK120 and X150, but was different in many ways. It was manufactured with a one-piece windshield (as opposed to the split screen) and the wing line didn't drop over the doors like the predecessors.
The interior was outfitted in leather as opposed to walnut. Many models were outfitted with the same 180hp 6-cylinder engine as the XK140, but in later years more were upgraded to a 210hp SE engine.
Production ended in October, 1960. A total of 2,265 were built.
