Acclaimed Driveline Technology

The TDV8 engine is mated to Range Rover Sport’s sophisticated full-time 4x4 driveline. Electronic control continuously adapts the change characteristics of the ZF six-speed automatic transmission to the prevailing driving style. In addition, the CommandShift mode also provides manual gearchange when required, providing even greater driver involvement.

Land Rover’s Positive Torque system is standard on all TDV8 derivatives, providing faster downshifts by automatically blipping the throttle to match engine and road-speeds.

When not locked, the four-wheel-drive system’s electronic centre differential continuously adjusts the front-to-rear torque split to help optimise traction, whatever the surface. The two-speed shift-on-the-fly transfer box incorporates a low-range reduction gear, designed to help achieve Range Rover Sport’s class-leading standards of off-road gradeability and control.

Extraordinary Composure, Agility And Balance

TDV8 derivatives share the acclaimed independent, double wishbone airsprung suspension system of other Range Rover Sport models and are available with either 19” alloy wheels with 255/50 tyres or 20” alloys with 275/40 tyres.

As Range Rover Sport’s chassis was designed from the outset to accommodate the TDV8 engine, it’s no surprise that the new derivative’s on-road agility and balance match the remarkable standards set by its V8 supercharged sibling.

And like the V8 supercharged derivative, Range Rover Sport’s highly effective Dynamic Response system is standard equipment on the TDV8. The system’s electronically controlled hydraulic actuators continually adjust Range Rover Sport’s roll stiffness in response to cornering forces, providing outstanding body control without the ride penalties associated with conventional roll bars.

The TDV8 shares its braking system with the Range Rover Sport Supercharged too, with four-piston Brembo front brake callipers and 360 mm front discs helping to achieve consistently excellent stopping power.

Unrivalled Breadth Of Capability

In addition to the TDV8’s impressive on-road behaviour, its off-road performance is class-leading.

Land Rover’s patented Terrain Response™ system, standard on Range Rover Sport, has been specifically tuned for the TDV8. The way the vehicle’s engine and chassis systems should react for optimum control on surfaces such as snow or grass is very different from the way they should react when - for example - crawling over rocky ground. Selecting the appropriate Terrain Response setting adjusts the responses of features from suspension ride height and axle articulation to gearchange and traction-control maps. This helps optimise the vehicle’s behaviour to suit the prevailing ground, leaving the driver free to concentrate on the route ahead. Terrain Response’s five settings cover ‘general driving’, ‘grass, gravel, snow’, ‘mud and ruts’, ‘sand’ and ‘rock crawl’ conditions, a range that underpins Range Rover Sport’s exceptional breadth of capability.
