Porsche has announced plans to enter this year’s Transsyberia Rally, an epic journey that sees competitors travel more than 6,200km through the roughs of Siberia. Last year, Porsche took the top three places in the event and to make sure it remains on top the sports carmaker has developed a number of modifications for its Cayenne S Transsyberia rally-SUV.

Engineers focused on improving the suspension set-up of the previous model, and added a number of reinforced parts including a newly-formed sump-guard, new front and rear panels, custom BFGoodrich all-terrain tires and a recalibrated air suspension system.

The Porsche Cayenne S Transsyberia still retains its sturdy roll-cage, twin bucket seats and six-point harnesses for driver and co-driver. The standard 4.8L normally-aspirated engine with direct fuel injection delivers 385hp (283 kW) and is mated to a six-speed automatic gearbox with a shorter final drive ratio than the regular Cayenne S. The SUV also features a weight-reduced sports exhaust system.

Like all other models in the Cayenne range, the Cayenne S Transsyberia features Porsche’s permanent AWD system, which feeds 62% of the engine’s torque to the rear wheels and 38% to the front. If slip is detected, the multiple-plate clutch, operated by an electric motor and controlled electronically, varies the distribution of power as a function of driving conditions and can send up to 100% of the engine’s power to either axle.

This year’s event will take place on the 11th of July and will once again travel from Moscow to Ulaanbaatar in Mongolia.
