It was also first built at a time when emissions regulations strangled the engine, 5-mph bumpers disrupted the flow of the lines in the bodywork and Jaguar’s reliability as a whole was not quite where you’d want it to be. But the XJS was in... Some people aren’t wild about this feature, but fans of the XJS generally consider them to be the car’s most charming design feature. And not only are they charming, but they add to the XJS being one of the more aerodynamic cars of its time, with a lower coefficient of drag than that of the E-Type. The front fascia on the car is quite different from that of the XJ. This was important because Jaguar also had the XJ Coupe at the time, and Jaguar wanted it to be easy to tell the two apart. The XJ Coupe was later dropped from the lineup, presumably because it was pointless to keep building both cars. And even when Jaguar decided to offer wood trim options in later versions of the car, the interior still looked great. The look is altogether much more sleek and sporting than that of the XJ, while still offering the same kind of acreage. Source: www.topspeed.com
