2018 Porsche Cayenne Turbo Air Brake, Aerodynamics, & Dynamic Chassis Control – Video
The new Cayenne Turbo is the first SUV to have an adaptive roof spoiler as a component of its active aerodynamics. Depending on the position, this optimises efficiency, increases downforce on the rear axle and, in the airbrake position, shortens the braking distance from higher speeds. At full braking from 250 km/h, the SUV comes to a stop up to two metres earlier as a result. The aerodynamic system therefore complements the effect of the new high-performance Porsche Surface Coated Brake (PSCB) which takes care of deceleration in the Cayenne Turbo as standard.
The tungsten carbide layer applied to the steel discs increases braking performance and resistance to wear while reducing the amount of brake dust at the same time, meaning less dirt on the rims. The top system in the programme remains the optional Porsche Ceramic Composite Brake (PCCB).
The new lightweight chassis of the Cayenne Turbo combines the best of three worlds: the precision of a sports car, the comfort of a saloon and the adaptability of an off-road vehicle. In particular, the combination of the new three-chamber air suspension with the active shock-absorber system PASM extends the range considerably. The concept of the new mixed tyres with standard dimensions of 285/40 at the front and 315/35 at the rear comes from sports car construction and produces even better longitudinal and lateral power transmission. Three air chambers per spring strut are used in the adaptive air suspension design, therefore the chassis is able to map different spring rates. With six selectable height levels, the ground clearance can be manually adjusted to suit the offroad terrain. They are also actively controlled via five new driving programmes for road journeys and off-road journeys.
Complemented by optional rear-axle steering, the electric Porsche Dynamic Chassis Control (PDCC) roll stabilisation connected to a 48-volt vehicle electrical system and Porsche Torque Vectoring Plus (PTV+), the new Cayenne Turbo achieves the driving dynamics of a sports car. At the same time, its everyday suitability in terms of parking and turning manoeuvres is improved, as is the comfort level.
