The award-winning Jaguar XJ flagship - which combines elegance, drama and sporting prowess - is now available with optional Sport and Speed Packs to further emphasise the performance aspect of its character.
With the XJ, Jaguar has created an entirely new template for the luxury performance saloon. The XJ seamlessly blends sporting potential, dynamic driving abilities and luxurious appointments; a class-leading combination that has gathered plaudits worldwide. The Sport and Speed packs further unlock the performance potential of the XJ both aesthetically and dynamically.
The Sport Pack - available throughout the XJ range - comprises a number of exterior and interior design options that clearly underline the assertive side of the car's personality. Externally the appearance of the XJ has been made even more dramatic with the addition of aerodynamically optimised changes to the bodywork and an alloy wheel design specific to the Sport Pack.
The functional aerodynamic changes of the Sport Pack allow supercharged XJ models to be additionally offered with the Speed Pack, which raises the limited top speed from 155mph (250km/h) to 174mph (280km/h).
Design
The elegantly integrated design changes that comprise the Sport Pack are not simply cosmetic, they allow Jaguar to offer the Speed Pack option, transforming the supercharged XJ models into the fastest saloons the company has ever built.
The result of extensive research in the wind tunnel and on track, the front of the car gains an aerodynamic splitter beneath the bumper to direct air beneath the car to reduce lift, and at the rear the bootlid lip has been extended to ensure a clean separation of air from the trailing edge of the bodywork. While ensuring optimal stability at high-speed, the Sport Pack maintains the standard XJ's sleek 0.29Cd aerodynamic figure.
The changes have been reinforced with a number of cosmetic additions that clearly distinguish the Sport Pack-equipped cars from other models. The bold Jaguar radiator grille, a key feature in the XJ's assertive face with its strong 'rear view mirror recognition' factor gains a gloss black mesh finish with the same treatment applied to the lower air opening and side vents.
Red painted brake calipers emblazoned with the Jaguar name are mounted behind new 20-inch 'Venom' alloy wheels with a diamond-turned sparkle silver finish to their eye-catching five split-spoke design. Newly designed split twin tailpipes (not available from launch) will leave other drivers in no doubt as to what car has just passed them.
The Interior
Reflecting the exterior styling changes and befitting its performance oriented remit, the Jaguar XJ Sport Pack offers interior changes that give driver and passengers a heightened sense of occasion and an indication of the dynamic abilities available.
The front seats are Jaguar's Performance version, which offer superb support for spirited driving. Trimmed in softgrain leather these offer a huge range of adjustment - including the enlarged side bolsters - to create a perfectly tailored driving position. Active ventilation supplies heated or chilled air as required to each individual front seats. At the driver's feet sit purposeful machined stainless steel pedals engraved with the Jaguar name.
The rear seats have been trimmed to match the front pair and the Sport specification will be offered in two purposeful colourways of Jet over Jet or Jet over Ivory. The eye-catching Piano Black trim that highlights certain touch surfaces in the XJ is contrasted in the Sport specification by subtly applied carbon-fibre highlights.
Performance
"A car capable of 174mph must have certain basic attributes - stability, aerodynamics, prodigious power and as little weight as possible. The XJ is blessed with all these qualities in abundance and with the addition of the Speed Pack it becomes an ever more impressive performance saloon." Mike Cross, Chief Engineer, Vehicle Integrity
The XJ benefits from superb aerodynamics and Jaguar's innovative lightweight aluminium architecture to offer weight savings of up to 150kg over its competitors. This offers tangible benefits in terms of economy, emissions, driving dynamics, agility and, of course, performance.
The Sport Pack is available on nearly all engine variants, including the muscular twin-turbo diesel, market-specific 3.0 V6 petrol and naturally-aspirated 5.0-litre AJ-V8 where it serves to emphasise the sporting character and driver involvement that are core strengths of every XJ model.
On supercharged AJ-V8 models, the Sport pack can be combined with the Speed Pack, which raises the electronically limited maximum speed from 155mph (250km/h) to 174mph (280km/h).
The supercharged petrol engines, no increase was necessary to achieve the higher top speed. The only changes necessary were a recalibrated engine management system, reworked software for the innovative virtual instrument display and adjustment to the tyre pressure monitoring system to take into account the heat generated by sustained high-speed motoring.
