Jaguar XK 150

Having developed disc brakes in the best testing conditions possible - endurance racing - Jaguar were ready to fit them to production cars and the first models to benefit were the new XK150's in May, 1957. Apart from the XK140 engine, which produced 190 bhp, the 150 could also be purchased in Special Equipment guise. Fitted with the 210 bhp B-type engine. Braking had never been the XK's strongest point and with performance and weight gradually increasing the new disc brakes adequately provided much needed improvement. The XK 150 and in particular, the 'S' series were a vast improvement on earlier models and are still a perfect every day thoroughbred car.
