2009 Porsche Cayenne S Transsyberia: The First Cayenne With Hardcore Off-Road Cred

The 2009 Porsche Cayenne S Transsyberia is not a gussied-up Cayenne designed to evoke the emotions of a hardcore off-road rally machine. The Cayenne S Transsyberia is a hardcore off-road rally machine.

To celebrated a new dynasty of Cayenne victories in the annual Transsyberia Rally series--this year Porsche Cayenne rally utes took the top six places in the race--the 2009 Cayenne S Transsyberia will be released to a limited number of Porsche customers, with 600 examples bound for the United States.

What starts as a Frankenstein between the Cayenne GTS and S trim levels, taking the motor from the S and the transmission and basic suspension components from the GTS, leaves the factory as a full-on Porsche rally beast.

Full 2009 Cayenne S Rally Transformation

The rear seats are removed in favor of a full roll cage, and the cockpit is optimized for interaction between driver and codriver. Case in point: the Porsche Cayenne S Transsyberia has had its glove box removed in favor of a Tripmaster computer which provides real-time information regarding every detail of the planned route.

Increased ground clearance, puncture-resistant tires with dual spares and waterproofing (!) up to the level of the windowsills show that Porsche has overlooked no details in making the 2009 Cayenne S Transsyberia as Rubicon-ready as anything available direct from the factory today.

No word on pricing as of yet. With all the fancy gizmos and gadgets, as well as an attention to detail befitting of any aftermarket tuner, figure a Cayenne S Transsyberia base price approaching or exceeding that of the ridiculously overpriced Porsche Cayenne Turbo S.

For those seeking similar performance without the luxury cache and base price to match, a heavily tuned Nissan Pathfinder could provide the same off-road thrills as the Porsche machine.

Still, there is something morosely exciting about showing up for trail days in a super-$100,000 Porsche ugly duckling with its tail on fire. And if you have the cash for it, why not?

Porsche competes with improved Cayenne S Transsyberia

Official Porsche Press Release

Dr. Ing. h.c. F. Porsche AG, Stuttgart, will again contest the Transsyberia Rally this year. Already at its debut in 2007, the Porsche Cayenne S Transsyberia proved its speed and excellent offroad qualities on the way from Moscow to the Mongolian capital of Ulaanbaatar. Three Cayenne S Transsyberia finished in the top three positions. For this year's edition of the Transsyberia Rally from 11th to 25th July, Porsche optimised the small series in several areas. The modified components are offered to customer teams around the world as a conversion kit.

In the modifications to the Cayenne S Transsyberia, primary importance was given to further improving the offroad capabilities and optimising the suspension set-up. The 2008-spec of the successful long distance racer features a stronger and newly-formed sump-guard. The front and rear panels were modified to allow a larger angle of driving slope. An all-terrain offroad tyre from BFGoodrich in the 265/ 5 R18 R dimension increases the ground clearance by 30 millimetres. Compared to last year, the higher and stronger side walls offer better protection against tyre damage. The air suspension was retuned based on the experiences of the 2007 Transsyberia Rally. The standard shock absorbers were replaced with special rally shocks. Particularly on the fast, bumpy sections, the vehicle's handling is substantially smoother than the 2007 version. Porsche Dynamic Chassis Control (PDCC), which features two active anti-roll bars to almost completely eliminate body sway in bends, was adapted to withstand the special demands of a marathon rally.

The Porsche Cayenne S Transsyberia is equipped with a massive safety cage, with two bucket seats and six-point harnesses for driver and co-driver. The standard 4.8-litre normally-aspirated engine with direct fuel injection delivers 385 hp (283 kW). The weightreduced sports exhaust system gives the Cayenne S Transsyberia a particularly powerful sound. For optimal acceleration, the six-speed automatic gearbox of the Cayenne S was combined with shorter final drive ratio of the Cayenne GTS. The transmission management was taken from the standard model and optimised for all-terrain purposes.

Like all other models in the Cayenne range, the Cayenne S Transsyberia features the permanent all-wheel-drive Porsche Traction Management (PTM), which feeds 62 percent of the engine's torque to the rear wheels and 38 percent to the front. The multiple-plate clutch, operated by an electric motor and controlled electronically, varies the distribution of power as a function of driving conditions, if necessary feeding as much as 100 percent 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. In this way, PTM is able to consistently calculate the degree of lock required on the two axles and distribute the power required to the axles. The PTM software underwent optimisation compared to its 2007 predecessor. A fitted transverse lock further enhances the offroad capabilities of the Cayenne S Transsyberia and is also available in the standard model as part of the optional Offroad Technology Package.

All Cayenne S Transsyberia are fitted, as standard equipment, with a navigation system that also enables teams to plan their route offroad and is controlled by the co-driver. Additionally, the glove compartment is replaced with a Tripmaster computer enabling the co-pilot to exactly scrutinize the route between navigation points. All of the control units are positioned within the water-tight interior, and all electric lines and wires have been installed in new positions. To prevent water from entering the car, the body and doors have been sealed up to the height of the side windows. The maximum depth when crossing rivers and streams is approximately 78 centimetres or almost 31".

The air intake for the engine is positioned above the hood. With a snorkel the air intake can be moved to roof height, ensuring that the front wave generated when crossing water is not able to enter the intake manifold. The regular foot-operated parking brake is replaced by a handbrake enabling the driver to intentionally oversteer the vehicle in a tight bend. Four additional headlights are mounted on the roof. For particularly difficult terrain and to assist in salvaging other vehicles, the Cayenne S Transsyberia comes with a winch easy to fit when needed and stored in the luggage compartment.

As standard equipment, the vehicle includes two fire extinguishers, two sand ladders, two full-size spare wheels, and two transport boxes for tools. Also included are two two-man tents, two heat-insulated ground sheets, four lashing belts, a nine-metre long salvage belt complete with tackle, a folding spade, a folding saw, an axe, a manually operated and adjustable headlamp, four towing bar openings and a Hazet toolkit.
