Following the XK 140 and the XK 120

The XK 140 came out as Jaguars top car in 1954. When production ended in 1957 there were a total of 8,884 produced. The XK 140 had a lot expected from it being the replacement for the hugely popular Jaguar XK 120. This was years after the popular Jaguar  XK 120  came out back in 1948 at the London Auto Show.

The XK 120 Roadster was the first sports car from Jaguar since 1940 and the car had an impressive record in competition finishing at or near the top in over one dozen events. In fact, the Jaguar XK 120 was so well accepted, the company had to make provisions for larger scale production beginning in 1950.

The Jaguar XK 150

The Jaguar XK 150 model was a revision of the XK 120 and XK 140 models. Essentially, the XK 150 was the beneficiary from the development and innovations of the two earlier XK models going back to 1948.

The basic XK chassis was kept on the XK 150.. The XK 120/140 bodyshell was restyled with high flow through fender lines, a curved one piece windshield and a wider grille. The one piece windshield was very popular at that time. Interior changes included  replacing the walnut veneer on the dashboard and door cappings with padded leather trim.

There were three different models of the Jaguar XK 150. These were the Jaguar Roadster, the Drophead Coupe and the Fixed Head Coupe. The latter two models came out in 1957 and the Roadster in 1958.

The automobile featured in this article is probably the fiercest of all the XK’s. This is the Jaguar XK 150 S Roadster. The car had a more higher tuned twincam engine. The engine also had different cylinder heads and three two-inch SU carburetors. The top speed of the XK 150 S was rated at 135 MPH. The Jaguar XK 150 S was only available with a manual transmission.
