Design plans for the XJS got underway in 1965, with the first production car being sold in 1975. The car was primarily designed by Malcolm Sayer, with input and control from Sir William Lyons. With Jaguar struggling financially at the time, the XJS needed to be a big success.

The highly anticipated XJS was seen by many as a direct replacement to the very popular E-Type. However, when the XJS was unveiled at the Frankfurt Motor Show in 1976, it was clear that the car was intended to be in a league of its own.

Externally, the XJS is most noticeable for its ‘flying buttresses’, sweeping from the top of the rear roofline down to the rear of the wings. Although initially widely criticised, this design gave the XJS an excellent drag coefficient – better than the E-Type, and allowing the XJS to reach speeds of comfortably over 150mph.
