The Sovereign represented the highest luxury specification for Jaguar models, sitting next to the XJR, which provides the ultimate performance. Sovereigns featured more elaborate/expensive wood veneer, commonly highly figured burr walnut with window control/ashtray trim panels also done in wood veneer as opposed to plastic in other models. The Leather is also of a higher quality and often features contrasting piping with seats being of the traditional fluted style. The suspension setup was biased towards touring and the wheels were normally 16″ or 17″ to provide high profile tyres for additional ride quality. Computer Active Technology System adaptive suspension was also offered as a rare option. Externally a Sovereign can be distinguished by the complete use of highly polished steel/chrome work around windows and rear light clusters as well as polished radiator grill and boot garnish. The cars are simply badged as “Sovereign” with no mention of “XJ”.
