The 2018 model year updates for the Jaguar XJ include the introduction of the Jaguar XJR575 performance flagship model, a host of technology upgrades and the addition of the latest driver assistance features.
The XJ is the pinnacle of the Jaguar brand’s sedan line-up. Its low-slung coupe-like stance, precise lines and carefully judged proportions ensure it is instantly recognizable as a Jaguar from any angle, according to the company.
The XJR575 features a unique version of the Jaguar 5.0-liter supercharged V8 engine. Delivering 575 horsepower and 517 lb-ft of torque, the engine powers the car from zero to 60 mph in 4.2 seconds and on to a top speed of 186 mph. The 25hp power increase is the result of enhanced engine calibration.
Steering feel and vehicle dynamics are enhanced by the application of electric power-assisted steering (EPAS) for rear-wheel-drive models. This set-up also underpins a range of available advanced driver assistance systems (ADAS) including perpendicular and parallel Park Assist, Lane Keep Assist, and Driver Condition Monitor.
All-wheel-drive (AWD) technology assists drivers in adverse weather conditions. The advanced system reacts to road conditions and can help deliver traction where it is most needed. Should the rear wheels begin to slip the system is designed to automatically redistribute torque to the front wheels.
In low grip conditions, the All-Surface Progress Control (ASPC) system becomes especially useful for RWD models. Developed for low-speed driving in adverse conditions, ASPC is designed to manage the brakes and throttle to deliver the best possible traction for the conditions at hand, assisting the driver in getting the vehicle to pull away smoothly: all the driver has to do is steer. ASPC is fitted to all models and operates between 1-19 mph, with the driver using the cruise control switches to select and maintain the desired speed.
The vehicle’s sense of effortless performance is maintained by the latest-generation of the Jaguar brand’s all-aluminum supercharged V6 and V8 gasoline engines, according to Jaguar. All feature direct injection, variable valve timing, forced induction and intelligent stop-start systems to the level of performance expected from a Jaguar product.
The 3-liter supercharged V6 develops 340 horsepower and 332 lb-ft of torque, and is available with rear- and all-wheel drive. Characterized by its linear power delivery and free-revving nature, this engine also produces a unique soundtrack thanks to meticulously tuned intake and exhaust systems, according to Jaguar.
All powertrains feature a specifically optimized eight-speed automatic ZF transmission. Each has been developed to provide the perfect balance of launch performance, shift comfort and vehicle dynamics, according to Jaguar.
Two variants from the 8HP’transmission family are offered in the XJ: the familiar 8HP70 transmission and the lighter, more compact 8HP45.
