Porsche engineers designed new front and rear axle systems to complement Cayenne's role as a sport utility vehicle
The front axle features a double wishbone suspension and a light-weight steel subframe assembly. The design of the upper and lower wishbones helps minimize distortion under load. The high-tensile steel subframe is specially designed to enhance the overall rigidity of the bodyshell. The benefits are not only more comfort and safety, but also even greater passive safety. In the event of an accident, the subframe deforms in a predefined manner to help maintain the integrity of the passenger cell. The rear axle system features a sophisticated multi-link geometry to assure exceptional traction and load carrying ability. As on the front axle, a steel subframe assembly with large rubber mounts helps minimize interior noise. In order to meet the unique demands of off-pavement driving, the lower suspension links and track rods are made of high-strength steel. The upper links are located high in the wheel arches and are forged in lightweight aluminum. The suspension itself is provided by carefully calibrated steel springs. Generous wheel travel allows the suspension to soak up bumps and ride smoothly over obstacles encountered in serious off-pavement use. From high-speed stretches on the autobahn to winding country roads, the Cayenne is always smooth and assured. |  |
