1957→1959 Jaguar XK150 3.4 Drophead Coupe

The third and final model in the XK line was the XK150. Easily identified by its new curved windshield, this model benefited from years of development since the first XK120 was launch in 1948. Jaguar described the roadster as “the same as the Hardtop Coupe, but with a convertible top, covered in the finest mohair, with fully lined interior, completely concealing the hood mechanism. Added seating accommodations in the rear for two children or one adult.”

One of the most important developments of the XK150 was the adoption of Dunlop disc brakes. These were often the focal point of the brochures which explained how the disc brake was first used on the Le Mans-winning C-Type of 1953.

Two of the availble options for the XK150 included an automatic transmission and wire wheels.

An optional Special Equipment Model was available which used the B-Type cylinder head and twin SU HD6 carburetors for 210 bhp. Other refinements included wire wheels, dual exhuast, windscreen washers. Above and beyond the SE model was the S-Type which used a straight-port cylinder head and three HD8 SU carburetors for 250 bhp @ 5500 rpm.
