Although having a family resemblance to the XK120 and XK140, the XK150 was radically modernized.

A one piece windscreen replaced the split screen and the wing line no longer dropped as much over the doors.

The bonnet was widened, opened down to the wings, and on the roadster the bulkhead was moved back four inches to make the bonnet longer.

In the interior, the XK140’s walnut dashboard was replaced by one trimmed in leather.

On the early drophead coupés, an aluminum centre dash panel with an X pattern engraving was fitted which looked similar to the early 3.8 E-type.

It was discontinued after June 1958.

Thinner doors gave more interior space.

The standard engine, the same as fitted to the XK140, was the 3.4 litre DOHC Jaguar straight six rated at 180bhp at 5750rpm but most cars were fitted with the SE engine that had a modified cylinder head with larger exhaust valves rated at 210bhp at 5500rpm.

Twin 1.75-inch SU HD6 carburetors were fitted.
