The combination of the latest chassis technology and the typical Porsche setup provides the basis for the outstanding handling characteristics of the new Cayenne GTS models. As in all Cayenne models, the active all-wheel drive Porsche Traction Management (PTM) system distributes the power optimally in every driving situation. The electronically and map-controlled multi-plate clutch of the PTM regulates power distribution between the rear and front axles. Driving conditions are monitored continuously in order to react to different driving situations. Among other things, sensors monitor the rotational speeds of all four wheels, the longitudinal and transverse acceleration of the vehicle as well as the steering angle, with the system adapting the distribution of power accordingly. The GTS models are equipped as standard with 20mm-lower steel-spring suspension that includes Porsche Active Suspension Management (PASM). The PASM active damper control system has been given an even sportier setup and is specially matched to the Cayenne GTS models. The slightly lower centre of gravity also contributes positively to the outstanding lateral dynamics of the vehicles.
Porsche Torque Vectoring Plus (PTV Plus), also standard, ensures direct and dynamic steering behaviour and always offers optimum traction when accelerating out of corners. The standard grey cast iron brakes with red brake callipers are matched to the longitudinal and lateral dynamics potential of the new Cayenne GTS models and are correspondingly generously-sized and powerful. On the front axle, six-piston aluminium callipers act on 390 mm discs to ensure optimum deceleration. At the rear, 358 mm discs and four-piston aluminium callipers are fitted as standard. The new Cayenne GTS models are equipped, again as standard, with 21-inch RS Spyder Design wheels with Black satin gloss painted finish – with 285/40 tyres at the front and 315/35 at the rear.
Air suspension, rear-axle steering, PDCC, PSCB and PCCB on the options list
Both driving performance and comfort can be optionally enhanced even further. For example, the standard steel-spring suspension can be replaced by adaptive three-chamber air suspension that includes PASM and lowers the car by 10 mm, making it possible to achieve an even greater spread between sportiness and long-distance comfort. Rear-axle steering provides greater agility and stability, thereby enabling Cayenne GTS models to steer more immediately and build up lateral acceleration even earlier. Rear-axle steering not only increases safety at high speed but also comfort in everyday driving thanks to it reducing the car's turning circle from 12.1 m to 11.5 m. The axles steer in opposite directions at speeds of up to approximately 80 km/h, which not only ensures significantly higher agility and steering precision, but also makes manoeuvring easier. At higher speeds, both axles steer in the same direction, resulting in even greater driving stability – for example when changing lanes on the motorway at high speed. Maximum steering angle on the rear axle is three degrees.
Porsche Dynamic Chassis Control (PDCC) active roll stabilisation significantly increases the spread between driving comfort and performance. It operates with a 48-volt system and is capable of adjusting the torsional stiffness of the anti-roll bars on the front and rear axles in milliseconds in order to actively stabilise the car's body. Under lateral acceleration of up to 0.8 g, any lateral inclination in a Cayenne GTS with two occupants onboard is suppressed.
The new Cayenne GTS models can also be equipped with the Porsche Surface Coated Brake (PSCB). Thanks to a thin tungsten carbide coating on the brake discs, this offers faster response, increased friction coefficients, less wear and up to 90 per cent less brake dust compared to conventional grey cast iron brakes. Characteristic of PSCB are brake callipers painted in White. For particularly dynamic drivers, Porsche also offers the Porsche Ceramic Composite Brake (PCCB), which has been tried and tested on the race track. In this case, ten-piston aluminium brake callipers, finished in Yellow, go with 440 mm internally vented ceramic composite discs. At the rear, PCCB combines four-piston aluminium callipers and 410 mm brake discs.
Porsche 4D Chassis Control links all active chassis systems
Porsche 4D Chassis Control is a central control system that links all the chassis systems operating in the vehicle. It centrally analyses all three dimensions of the driving situation (longitudinal, lateral and vertical acceleration) and, from the results obtained, the optimal driving condition information is calculated and made available to all relevant systems. This provision of information in real time represents the fourth dimension. Porsche 4D Chassis Control enables the chassis systems to respond proactively and in an integrated manner to the upcoming driving situation.
