Jaguar's flagship model - the XJ saloon - is now available with an optional Sport and Speed Pack. The Speed and Sport packs are available throughout the XJ range and compromise of a number of exterior and interior design options. Externally, the appearance of the XJ has been made even more aerodynamic with the addition of optimised changes to the bodywork and these packs also get a different set of sporty alloys. The interiors have undergone a change as well and the front seats in these cars are Jaguar's Performance version and they have the active ventilation which heats or chills them as per the requirement.
