New optional packages for the XJ deliver a sportier appearance and a vastly improved top speed.
A pair of option packs for the luxurious XJ has been revealed by Jaguar: the Sport pack, available across the range including the twin-turbo diesel, market-specific 3.0-liter V6 petrol and naturally-aspirated 5.0-liter V8; and the Speed pack for the supercharged models, which simply removes the electronic limiter allowing it to hit a top speed of 174mph. For the exterior the Sport Pack adds an aerodynamic splitter under the front bumper and the rear gets an extended boot lip spoiler.
A gloss black mesh finish applied to the front grille, side vents and lower air opening, and 20-inch Venom alloys hiding red brake calipers complete the subtle body kit. On the inside the front seats are replaced by Performance versions with heavier bolstering and finished in soft-grain leather. Carbon-fiber trim and stainless-steel pedals engraved with the Jaguar name are other notable embellishments. The Sport and Speed packages can only be combined on the flagship 504hp supercharged V8 model, about which Mike Cross, Chief Engineer, vehicle integrity said: "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."
