Porsche Cayenne S TranssyberiaThe Porsche Cayenne S Transsyberia is a typical Porsche through and through, tailored precisely to the needs and requirements of the sporting, ambitious customer - which in this case means a car tailored specifically to the requirements of long-distance rally racing.
Even Better off the Beaten Track Like all other models in the Cayenne range, the Cayenne S Transsyberia also comes with Porsche Traction Management (PTM) permanent all-wheel drive. In its basic mode, PTM feeds 62 per cent of the engine's torque to the rear wheels and 38 per cent to the front. Then a multiple-plate clutch operated by an electric motor and controlled electronically is able to vary the distribution of power as a function of driving conditions, if necessary feeding as much as 100 per cent of the engine's power completely to the front or rear. The map-controlled longitudinal lock and the differential lock on the rear axle respond not only to lack of traction on the front or rear wheels, but also benefit from sensors measuring the speed of the vehicle, its lateral acceleration, the steering angle and the position of the accelerator pedal. Using this information, PTM is able to consistently calculate the degree of lock required on the two axles and feed precisely the power required to the axle at the front and rear. A transverse lock fitted additionally in the Cayenne S Transsyberia serves to enhance offroad driving qualities to an even higher standard (and is also available in the regular production model as part of the optional Offroad Technology Package). Particularly in heavy terrain, PDDC Porsche Dynamic Chassis Control, interacting with air suspension and PASM Porsche Active Suspension Management, enhances traction to an even higher standard. And should the driver activate the low-range mode on the six-speed automatic transmission by means of the control paddle, PDCC will automatically switch over to the offroad mode, the system thus allowing maximum articulation of the axles. In the Special Offroad Mode provided by the air suspension, the maximum depth when crossing rivers and streams, etc, is approximately 75 centimetres or almost 30". To make such an extreme depth possible, both the body and the doors are sealed off against the penetration of water all the way up to the side windows. And using a flexible air filter snorkel, the air intake has been moved up even further to the roof of the vehicle, ensuring that the front wave typical when crossing water is not able to reach, let alone enter, the intake manifold. The wheels and suspension of the Cayenne have naturally also been modified for the most extreme, long-term demands of rough tracks and rocky surfaces. As an example, the doublearm front axle comes with reinforced track control arms, with track itself being increased by 34 millimetres or 1.34" for extra stability. The usual high-speed tyres fitted on the regular model are replaced by special offroad tyres measuring 255/55 R 18 T and homologated for speeds of up to 190 km/h or 118 mph. The tyres themselves are fitted on 18-inch, 15-spoke Cayenne S II light-alloy wheels and the rim hubs are finished in orange, like on the Porsche GT3RS. Massive Safety Cell within the Interior
Optimised for Minimum Weight All Round To set off the extra weight of the safety cage and rally equipment, and to further lower the vehicle's centre of gravity, the rear seat bench, interior body panels and sound-proofing material have all been removed from the car. Central locking, in turn, is replaced by a manual door opening mechanism on the front doors with orange-coloured opening and closing loops. Both the rear window and the side windows at the rear are made of light polycarbonate, while the side windows at the front, as on all Cayenne models, feature special hydrophobic treatment at the outside to make water run off more quickly and smoothly and ensuring that the glass remains far cleaner for far longer than with conventional windows. As another important advantage, both the driver and front passenger enjoy the benefits of lightweight sports seats with a leatherette/Alcantara cover. Sporting Exterior The new models in the Cayenne range are even more sporting and dynamic also in their looks than their predecessors. And so it is no surprise that the Cayenne S Transsyberia comes with the same brand-new front end as well as the dynamic rear-end design of the new model enhanced to an even higher standard, extra-large air intake scoops bearing clear testimony to the car's superior power and performance. On the tailgate the Cayenne S Transsyberia boasts a roof spoiler with a double-wing profile fitted in position to provide even greater stability at high speeds. The front and rear air dams, in turn, are finished in stainless steel, and orange-coloured wheels give the Cayenne S Transsyberia a sporting look, making the vehicle easily recognisable at very first sight. At the side this special rally model proudly boasts orange-coloured stripes bearing the name Cayenne S Transsyberia 2007" in a look similar to that of the Porsche Carrera GT3 RS. The Cayenne S Transsyberia is available exclusively in two special colour schemes either Basalt Black Metallic or Crystal Silver Metallic. And matching the model designation at the sides as well as the wheel rims, contrasting elements such as the exterior mirrors, the rear wing, the additional headlights and crossbars on the cooling air intakes are all finished in orange.
