WM 4X00IN Cayenne System Overview (All Models): Information: General
WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
The development team is expected to meet various requirements in developing the Cayenne, e.g. sporty vehicle handling, tough off-road mission and full suitability for everyday use with maximum driving safety. Through overall vehicle fine-tuning of the individual systems, such as axles, steering, tyres, aerodynamics and drive design, very good vehicle handling features were implemented in both on-road and off-road operations with the following technical specifications:
- Single-wheel suspension with steel springs using a large-base double control arm front axle and a multi-link rear axle (standard for Cayenne S)
- Level adjustment system with full-supporting air suspension on both axles and electronically regulated shock absorbers (standard for Cayenne Turbo, optional for Cayenne and Cayenne S)
- Tube-type stabilisers on front and rear axle or hydraulically disengagable off-road stabilisers (optional for all Cayenne models as part of Porsche Traction Management Plus)
- Rack-and-pinion steering gear with hydraulic assistance or speed-dependent Servotronic steering assistance (optional)
- Extensive range of wheels and tyres, high-performance summer tyres, winter tyres, All Season tyres and All Terrain tyres.
- Tire Pressure Monitoring - TPM (optional)
- Operating brakes customised to suit driving dynamics
- Porsche Stability Management (PSM)
- Porsche Traction Management (PTM) or optional Advanced Off-Road technical package with PTM Plus.
