Jaguar XJS Hess & Eisenhardt

The jaguar xj-s (later called xjs) is a luxury grand tourer manufactured and marketed by British car manufacturer jaguar cars from 1975 to 1996, in coupe, fixed-profile and full convertible body-styles. There were three distinct iterations, with a final production total of 115,413 units over 20 years and seven months.

From July 1981, the xj-s was renamed the xj-s he and received the new high-efficiency v12 engine for much better fuel economy. With the fire ball combustion chamber designed by Swiss engineer Michael May, power output was increased as a by-product to 295 hp (220 kw; 299 ps) or 263 hp (196 kw) in north America.[10] .

The Hess & Eisenhardt coach building firm was located in Ohio, USA, and built convertible modifications for the xj-s under contract from jaguar, before the official jaguar-built xj-s full convertible became available in 1988. The number of h&e jaguar xjs produced is unknown, partly because a fire at the Hess & Eisenhardt factory destroyed most of the records pertaining to the jaguar xjs conversions. According to some sources, a total of 2,100 cars were converted.
