Range Rover Evoque Gets Third-Gen MagneRide System

Ensuring maximum driving quality and capability both on and off road for the Evoque, Range Rover is employing third generation of BWI Group’s MagneRide. BWI Group’s twin coil system enables exceptional dynamics and comfort without compromising all-terrain ability.

Range Rovers have always been famous for their superb ride comfort and excellent road behavior, combined with uncanny off-road versatility. That’s why they’ve been the king of SUVs for a very very long time. The Evoque might be the baby Rangie, but rest assured LR group is not going to risk their reputation by something imperfect.

How MagneRide system works is actually quite boring, but in brief it has a special fluid in its dampers with tiny metallic particles which means they can constantly adjust themselves using electricity. It has sensors and stuff to predict the best compromise at each given moment. Tell you what, read the complete details of it in the press release below.

The third generation of BWI Group’s MagneRide is entering production on the Range Rover Evoque as its Adaptive Dynamics technology. The addition of a twin-wire dual coil actuator to the system provides faster response and a greater range of damping control, to deliver very high levels of traction, stability and comfort both on and off the road. BWI Group also supplies the passive twin-tube dampers for the vehicle’s standard suspension configuration. BWI has a long history of supplying premium dampers for off-road vehicles.

“With around half a million units already produced, MagneRide technology is robust and well-proven on high-performance cars, supercars and large SUVs,” says BWI’s manager, forward engineering controlled suspensions, Olivier Raynauld. “The third generation of MagneRide, with faster response and wider dynamic range, effectively removes the need for chassis engineers to compromise between comfort and handling – whether driving over rocky tracks or smooth highways. We are proud of its contribution to the Range Rover Evoque’s outstanding driving experience.”

MagneRide uses a Magneto Rheological (MR) damper fluid which contains tiny metallic particles that can be quickly but temporarily magnetised by energising electrical coils in the damper piston. When the current is off, the particles are randomly dispersed and the damper is in its softest setting. Applying a current magnetises the particles, which then attract each other in proportion to the strength of the magnetic field, increasing the resistance to flow and stiffening the damping. The result is an ability to vary the damping force almost instantaneously over a wide range, just by varying the current applied. The system has low energy requirements of typically less than 20W per damper.

The third generation of the system replaces the damper’s single electrical coil with two smaller coils, and a bespoke ECU with optimised control algorithms. The changes provide quicker ‘current-off’ performance, giving the new system a faster transient response that helps to isolate the vehicle occupants from the texture of the terrain, especially when driving off-road.

The new dual-coil architecture also helps to extend the dampers’ dynamic range (a ‘softer soft’ and a ‘harder hard’), even at the low body velocities typical of off-road driving that are difficult to control with conventional damping technologies. As well as directly improving comfort and handling, this allows the influence of the roll bars and springs to be reduced, improving a further area of ride-handling compromise that can be particularly challenging for off-road vehicles.

Unlike conventional semi-active suspension systems that use complex electro-mechanical valving, MagneRide is mechanically very simple, having no small moving parts and fewer parts overall than a traditional passive damper. There is no off-road button to push and, unlike conventional active suspension systems, the response is always proportional, not stepped. Regardless of the Evoque’s Terrain Selector position, the technology provides the optimum contact between the tyres and the road surface and the best compromise between response and comfort.

“Land Rover wanted a new level of suspension control for the Evoque,” explains Raynauld. “Adaptive Dynamics, using BWI’s MagneRide dampers provides that control across all road surfaces and under all conditions.”

Other automotive applications
European production vehicles currently available with different versions of MagneRide include the Audi TT, Audi R8, Audi A3, the Ferrari 599 GTB Fiorano, the Ferrari California and the widely-acclaimed new Ferrari 458 Italia. In the US, the technology features on Corvettes and Cadillacs, including the ZR-1 and CTS-V models, which have established Nürburgring lap records for their respective categories. It is also used in the Cadillac Escalade and the Acura MDX. The Porsche 911 uses the technology in its active engine mount system.
