One of the products of Jaguar’s recent drive to improve quality and reliability is the latest version of the XJS coupe (above), dubbed “H.E.” for “high efficiency”. The basic format of this highly successful sports coupe is unchanged, although major cylinder head changes on the 5.3-litre V12 engine (left) have resulted in startling improvements in fuel consumption. Below left, the XJS H.E. interior is a tasteful mixture of top-quality leather upholstery and elm burr trim while the spare wheel in the deep boot (below) is covered with lavish carpeting to similar standards. (For road test, see page 1062).
