For the new Cayenne models, the main development goals in the areas of driving dynamics and performance were as follows:
- Increased driving pleasure and agility
- Improved comfort and day-to-day usability
- Improved driving dynamics

In order to achieve these goals, all chassis variants and the chassis control systems were enhanced. In addition to design modifications on the front and rear axles, new materials are also used for consistent lightweight construction. The measures include the following:

Weight reduction through lightweight construction:
- Wheel carriers, pivot bearings, front wishbones made of aluminum
- Pedal bearing block and torque support made of plastic
- Consistent lightweight construction of rear wishbones, transmission support, tie rods and drive shafts as well as optimized steel springs (High Performance Thermotec Process)

Weight reduction by design measures:
- Closed air-spring system
- Electric parking brake
- Omission of mounting saddle on the front axle

The weight reduction of approx. 139 lbs (63 kg) does not just lead to enhanced driving dynamics with low fuel consumption, but also makes a decisive contribution to improved comfort by reducing the unsprung masses.

Driving dynamics

The all-wheel drive Porsche Traction Management (PTM) was also enhanced to further increase driving dynamics. In addition, two new options are available in the form of Porsche Active Suspension Management (PASM) for the steel spring suspension and Porsche Torque Vectoring Plus (PTV Plus). The wheelbase was also lengthened by 40 mm to 2,895 mm.
