OVERVIEW
An advanced multi-link rear suspension is introduced providing superior dynamics and refinement with enhanced wheel articulation. The compact design of the rear suspension allows for a generous luggage compartment area which is also capable of packaging the occasional third row of seats.
Lightweight aluminium chassis components are used extensively to advance suspension performance by increasing stiffness and reducing un-sprung weight, while also reducing total vehicle weight.
DESCRIPTION
The vehicle has a fully independent suspension system with an advanced new multi-link design, which delivers enhanced dynamics and refinement together with a compact layout providing increased vehicle interior space.
The rear suspension has been specifically developed to offer responsive and agile handling together with supreme ride quality and refinement. Excellent wheel travel and articulation aids the vehicle to class-leading off-road performance, but without the intrusive suspension towers of a traditional strut-based layout.
The compact multi-link layout enables a more spacious luggage compartment, with excellent shoulder and elbow room and the option of 5+2 seating, plus increased luggage space. The suspension layout is also optimised to allow a short rear overhang, even with a full-size spare wheel mounted under the floor. It is also possible to package an underslung reduced section spare wheel along with 5+2 seating due to the exceptionally space efficient suspension architecture.
Both the rear suspension lower control arm and wheel knuckle are produced from thin-walled hollow aluminium castings, delivering additional weight savings.
The rear suspension is mounted on an optimised steel subframe which is light and stiff for optimum steering response, chassis performance and refinement.
