Production years: 1957 - 1961

The final XK from this period was the XK150, produced form 1957 to 1961 also in the three body types. Essentially of the same format, the big change was in the exterior and interior styling. The former was more slab-sided and wider, yet retained the essence of the original XK120, but now using a wrap-around one-piece windscreen. internally the car benefited from revised seating and a new dashboard layout. Initially powered by the existing 3.4 litre XK engine, later a new 3.8 litre version became available and ’S’ models of both engines utilising triple carburettors (instead of two).
