IN ADDITION to the reassuring grip provided with the all-wheel drive system, the X-Type offers dynamic stability control (DSC) as an option on both Sport and SE models. Like other systems of this type, Jaguar's DSC system presides over the anti-lock brakes, traction control and yaw control of the vehicle. The system will intervene via the brakes and/or engine power to keep things under control when the electronic brain detects the car is about to reach the point of no return. DSC can be switched off by pressing a switch on the centre console. At the core of the X-Type's sophisticated multi-media system is an optical data network - a wide-band "ring" of optical fibres, which provide fast and high quality data transfer.
