Delphi Help Land Rover Achieve The Highest Standards Of Handling And Comfort

Range Rover Sport


Three new technologies from Delphi Corp (NYSE: DPH) are helping the new Range Rover Sport achieve levels of dynamic performance and comfort that are widely regarded as setting new standards for a high-performance SUV. The combination of advanced air suspension and a new compact version of Delphi’s Active Stabiliser Bar System (ASBS) has been credited with helping to provide exceptional handling combined with best-in-class ride. The new vehicle is also available with a new generation of Delphi’s Forewarn Smart Cruise Control that will help the driver maintain a driver-selected time gap behind the vehicle ahead at highway speeds.

"Land Rover wanted to define a new niche for an SUV that would combine comfort and sophistication with very high-performance. That’s an ambitious goal in a sector where the quality of competition is already very high," explains Rene Haep, Delphi’s customer director responsible for Land Rover. "There could be no compromise in the brand’s legendary off-road capability and there were other challenges, such as the need to fit 20 inch wheels without sacrificing ride quality. It was a tough challenge that required a fresh approach to several established areas of technology."

Dynamic Response system with Delphi’s new rotary actuators

Delphi’s new rotary actuators replace conventional stabiliser bars to provide an exceptionally compact roll control system that is thought to be the most powerful and most energy efficient in production today. Delphi worked closely with Land Rover’s chassis team, who integrated Delphi ASBS actuators and valve blocks at both the front and rear, making Range Rover Sport the first vehicle to be fitted with this new technology.

A traditional stabiliser bar improves vehicle stability through corners by reducing roll angle and managing the tyre to road interface. Heavy vehicles with a high centre of gravity typically require stiff, large diameter stabiliser bars but these will substantially reduce ride comfort and refinement and can also reduce traction in some conditions. Traditional stabiliser bars also restrict wheel travel, potentially compromising off-road behaviour, and can create an effect known as ‘head toss’ that can be particularly uncomfortable in vehicles where the occupants are seated high. Land Rover’s Dynamic Response system, incorporating Delphi’s ASBS technology, helps minimise all of these issues.
