New range-topping XJR575 does 0-62mph in 4.4 seconds.
Jaguar has announced updates to its flagship XJ saloon.
The whole range benefits from upgrades to the technology and safety features to be found in the car, while the headline news is the introduction of the XJR575 performance model.
The XJR575 gets a 25hp increase to its supercharged 5-litre engine’s power rating, meaning 575hp and 516lb-ft of torque, resulting in a 0-62 time of 4.4 seconds and top speed of 186mph.
Two new colours have been created at Jaguar Land Rover’s Special Vehicle Operations division in Coventry: Velocity Blue and Satin Corris Grey.
Design boss Ian Callum says that he has tried to use ‘intricate details’ to ensure that drivers and passengers feel like they are in something ‘truly special’.
The XJR575 gets a full bodykit, which includes front and rear spoilers and vents in the bonnet as well as 20-inch wheels and 575 branding throughout the interior.
The cost of the new R-badged XJ model will be £93,710.
Across the range, the XJ now features a 10-inch touchscreen on the centre console that offers a customisable home screen. Connectivity is improved with 4G wifi that up to eight devices can connect to.
The system behind the touchscreen uses a quad-core processor to ensure a rapid response from the fancy graphics. One neat feature of the navigation is Commute Mode, which learns your drive to work and automatically suggests alternative routes if there is traffic on the way to the office.
Safety-wise, the XJ range now boasts Forward Traffic Detection, which helps when emerging from blind spots at junctions and other times when forward visibility is restricted, Lane Keep Assist and a Driver Condition Monitor that watches the person behind the wheel for signs of fatigue.
Jaguar also claims ‘superior functionality' on its Autonomous Emergency Braking pedestrian safety system, which uses a forward-facing stereo digital camera between 3 and 37mph to automatically brake the car when a collision is detected.
The 2018 Jaguar XJ is now available to order from UK dealers priced from £59,995 for the 300hp 3-litre diesel V6 model.
