Background
Conceived as a comfortable and long-legged Grande Routière, rather than an out-and-out sports car like the preceding E Type, the XJ-S made use of the Jaguar XJ6/XJ12 saloon platform and running gear.
Shorter in the wheelbase than its saloon siblings, the XJ-S debuted as a V12-powered coupé, with six-cylinder and soft-top versions following in the 1980s.
The car's 150mph performance was not achieved without penalty however, its prodigious thirst causing sales to nosedive as oil prices soared. However, the arrival of the HE (High Efficiency) V12 in 1981 and the introduction of the smaller six enabled it to weather the storm.
Jaguar's first response to demands for an open XJ-S was somewhat conservative in engineering terms. The XJ-S had not been designed with an open version in mind, so a Targa-style arrangement was adopted, which retained a substantial roll hoop in the interests of maintaining rigidity in the absence of a fixed roof.
Two removable roof panels were stored in the boot, and the cabriolet did away with the coupé's two occasional rear seats in favour of a pair of luggage lockers topped by a parcel shelf. Essentially an exercise in niche marketing to test public reaction, the XJ-S cabriolet was assembled by outside specialist contractors, with bodyshells transported back and forth across the Midlands before returning to the Brown's Lane factory prior to final despatch.
The cabriolet's favourable reception demonstrated that there was indeed sufficient demand to justify production of an open XJ-S, and Jaguar proceeded to develop a conventional full convertible. In total, Jaguar produced 3,925 V12 5.3-litre cabriolets and 7,420 V12 5.3-litre convertibles.
