A comprehensive programme of chassis refinements has been introduced to the Range Rover Sport for 2010. The enhancements transform the dynamics and handling characteristics of the vehicle, allowing drivers to fully exploit the capabilities of the new, high-performance engine line-up.

Adaptive Dynamics System

The 2010 Range Rover Sport features a new Adaptive Dynamics system, which works in conjunction with the existing Dynamic Response system to enhance control of the vehicle's ride and handling.

Land Rover has employed the world's first production system for this model-based predictive technology, which continually optimises damper settings for the widest possible range of conditions. Conventional dampers are replaced by precision DampTronic Valve Technology damper units, which incorporate continually adjustable damper valves.

The predictive technology enables damper settings on each wheel to be continuously refined between 'soft', comfort-oriented settings and 'hard', firm body control settings; damper pressure on each wheel is monitored 500 times per second. The system optimises the vehicle's body and ride control, instantly responding to the demands of the prevailing driving style and of the terrain encountered, in both on and off-road situations.

Greater Driver Involvement Through The Wheel

Steering response is improved on the Range Rover Sport with the stiffening of the front suspension lower arm forward bush, which enhances the sense of driver involvement with the vehicle at higher speeds.

The variable-ratio steering rack complements this by reducing 'twitchiness' during high-speed cruising - and increasing sensitivity at higher lock angles.

The Range Rover Sport is equipped with a new braking system which has been comprehensively updated to provide enhanced stopping power and improved driver feel.

The brakes for the diesel model are based on the four-piston, opposed-caliper performance system from the outgoing supercharged model. The updated system employs 360 mm ventilated front discs with new, twin-piston sliding calipers made from cast iron for enhanced pedal feel. The rear features 350 mm ventilated discs with lightweight aluminium, single-piston sliding calipers.

The braking system for the supercharged model has been developed in conjunction with performance brake specialist Brembo. This system employs 380 mm ventilated front discs with unique, lightweight aluminium, six-piston, opposed-action monoblock calipers. At the rear, 365 mm ventilated discs with single-piston sliding calipers are fitted.

Greater Control and Safety Around Bends

A refinement to the Stability Control system helps automatically slow the vehicle if taking a bend too fast, enhancing driver control.

The system operates according to steering inputs from the driver. In extreme cases, automatic braking intervenes to reduce vehicle speed: the braking pressure level applied varies according to the severity of the situation.

This feature is complemented by the new Roll Stability Control system, which is designed to intervene if, in an extreme situation, the possibility of a rollover is detected. In such situations, the system is designed to take over and perform very rapid, wheel-specific braking to help reduce speed and marginally widen the cornering radius.

In more extreme cases, the system is designed to initiate marginal understeer by sharply increasing brake force on the outer wheels, again widening the turning radius.
