In 1957 Jaguar introduced the XK150, a replacement for the XK140. The XK140 had been a replacement for the XK120 which had started the XK series with its elegant styling and impressive 120 mph capabilities. At the time, the XK120 was the fastest production vehicle in the world. The XK150 had many similarities to its predecessors but it featured modern styling and improved mechanics. When the XK150 was introduced, it could be purchased in DropHead Coupe or FixedHead Coupe configuration. The Open Two Seater (OTS) Roadster version appeared a year later.
The base engine was a DOHC 3.4 liter straight-six that produced 180 horsepower. Most of the vehicles were outfitted with the SE version which had a modified cylinder head, dual SU HD6 carburetors, and larger exhaust valves bringing the horsepower rating to 210. Performance was further increased in 1958 when Jaguar enlarged the bore bringing the liter capacity to 3.8 and the horsepower rating to 220. The 'S' model featured three SU HD8 carburetors and a modified cylinder head bringing the horsepower rating to 260.
The XK120 suffered from poor steering. This was resolved by the adaptation of a rack-and-pinion unit on the XK140. The XK150 used the similar rack-and-pinion configuration, though still lacking power-assistance. The chassis was also similar to its predecessor. Disc brakes were standard on all four corners of the vehicle. The wheels could be ordered as Wire or as discs wheels.
Improvements continued in the interior of the vehicle. With roll-up door windows and door handles, the XK150 was more civilized. The longer hood meant the XK150 Roadsters were just a two seater unlike its 2+2 predecessors.
During its production lifespan lasting from 1958 through 1961, the Fixed Head Coupes were the most popular with 4445 examples being created. That figure was followed by the Drop Head Coupes with around 2670 examples. There were around 2260 Roadsters produced. The Roadster production figures would have been higher if they had not been introduced ten months after the Fixed and Drophead Coupe versions.
The XK150 continued the elegance and performance established by the XK120 and reinforced by the XK140. The long flowing lines of the hood gracefully curved towards the vertical grille which hid a potent engine that made the car legendary. By Daniel Vaughan | Mar 2006
