WM 4X00IN Cayenne System Overview (All Models): Information: General
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.
