The all-new XK has a completely new, high-performance braking system, tested extensively over many hundreds of laps at the gruelling Nürburgring test track in Germany, where Jaguar has a dedicated research facility. The result is greater braking power and more responsive feedback to the enthusiastic driver.
Larger, ventilated discs contribute to better pedal feel, optimum stopping distances and resist fade during extended hard use. The braking system also includes four-channel ABS, Electronic Brake Force Distribution, Hydraulic Brake Assist to increase brake pressure during an emergency stop, and Jaguar’s Electronic Park Brake function.
Unlike conventional digital ABS systems used on many cars, the all-new XK’s ABS system can vary the brake pressure at each wheel using analogue valves in the hydraulic control unit. This gives more refinement to the hydraulic pressure control and allows drivers to benefit from increased steering input during heavy braking.
The all-new XK’s Servotronic 2 steering is adapted for a sports car from the XJ saloon, to give easy low-speed manoeuvring with optimum high-speed feedback under all conditions.
Beyond the exceptional new pedestrian impact safety systems, the XK also includes a host of other safety features. These include the option of a Tyre Pressure Monitoring System and run-flat tyres, Jaguar’s Protec dynamic headrest system to protect against whiplash injuries, Forward Alert which uses the optional Adaptive Cruise Control’s forward-facing sensors to scan the road ahead 10 times every second to warn of a potential collision, and the new switchable Dynamic Stability Control with Traction Control System (Trac DSC).
A new active front lighting system is also offered as an option on the XK, enhancing the Bi-Xenon intelligent lighting that is standard on the car. This feature provides enhanced visibility in the dark during higher speed cornering by swivelling the dipped beam lens depending on road speed and the angle at which the steering wheel is turned.
Like any of the great Jaguar sports cars of the past 50 years and more, the all-new XK pushes the boundaries of sports motoring. It is the most technically advanced Jaguar ever, and undoubtedly one of the most beautiful. It is lighter, faster and better equipped than the model it replaces, with substantial improvements in performance, driving dynamics, braking, safety and economy.
Being a Jaguar, it combines the comfort, style and craftsmanship of a luxuriously equipped grand tourer with the driving dynamics of a true sports car. It captures the unique joy of driving that Jaguar drivers expect. In the finest Jaguar tradition, it is a truly beautiful, fast car, the product of advanced engineering and fine craftsmanship. It offers style, comfort and luxury. But it also keeps true to what sports car motoring is about - and that is the undiluted thrill of driving.Published 26 August 2005
