JAGUAR SEQUENTIAL SHIFT?

The new XF offers a choice between six-speed and eight-speed automatic transmissions. Both options give smoother gear changes, constantly adapted to suit the style of driving. In addition, drivers seeking greater involvement have the option of changing gears manually, with paddles behind the steering wheel.

JAGUARDRIVE SELECTOR? AND JAGUARDRIVE CONTROL?

The automatic transmission is controlled by the beautifully designed JaguarDrive Selector?, which rises into the driver’s hand once the ‘Start’ button is pressed. The driver simply turns the selector to engage transmission settings, or to move from Drive to Sport mode. JaguarDrive Control? offers further driving modes. Dynamic mode where fitted offers more responsive acceleration, while Winter mode gives more progressive control in slippery conditions.

INTELLIGENT STOP/START TECHNOLOGY

New XFs powered by the innovative 2.2 Litre Diesel engine will feature Intelligent Stop/Start technology. This is a first for Jaguar and a first on an automatic diesel saloon from a premium brand. The intelligence of the system lies in its ability to detect when the engine is not needed. The engine will restart as soon as the driver releases the brake pedal and will be operating at ‘idle’ before their foot reaches the accelerator. As well as reducing CO2 emissions, the system can deliver savings of 5–7% in fuel efficiency, depending on conditions.

DYNAMIC STABILITY CONTROL

The Dynamic Stability Control (DSC) has two settings. The default setting comes into play as soon as it detects the wheels slipping. The Trac DSC setting, on the other hand, allows some slipping and overspin before it intervenes – this allows for a sportier drive and is also essential with snow chains.

ADAPTIVE DYNAMICS

The Adaptive Dynamics system analyses speed, steering and body movements 500 times a second and adjusts the suspension with electronic dampers to achieve the ideal balance between comfort and precise handling. The system is standard on XFR, and is available on other models as part of the Dynamics Pack.

ACTIVE DIFFERENTIAL

The electronic Active Differential on the new XFR is designed to detect any slipping and vary the power supplied to each wheel to help keep the car as stable as possible.

SERVOTRONIC STEERING

The new XF’s variable-ratio power-assisted Servotronic steering makes it easier to park and manoeuvre and gives more precision at higher speeds.

CRUISE CONTROL WITH AUTOMATIC SPEED LIMITER

Working in tandem with cruise control, an Automatic Speed Limiter allows the driver to select a maximum speed that should not be exceeded.

ADAPTIVE CRUISE CONTROL

When Adaptive Cruise Control is fitted, a microwave radar in the front bumper is designed to sense if the vehicle in front slows down, and then use the throttle and brake to maintain a constant time gap. Once the road clears it will take the car back up to the previous speed. The radar also operates a Forward Alert, which gives the driver an audible warning if the traffic ahead slows quickly or another vehicle moves into the same lane. Adaptive Cruise Control is now compatible with the optional Aerodynamic Pack.

ELECTRIC PARKING BRAKE

The new XF’s braking system works with the  JaguarDrive Selector? to release the parking brake as the car drives away. The driver can also choose to operate the parking brake manually. "Refinement is terrific and power delivery creamy smooth." Autoweek - Online, March 2009
