Last year, a pair of series-built Porsche Cayennes that were further modified by the customers who purchased them drove to victory in the 10,000km-long Transsyberia Rally. Spurred on by the success shown by those two cars, Porsche has built a small production run of at least twenty-six 2007 Cayenne S Transsyberia SUVs, all of which will compete in the 2007 rally. The full range of Porsche’s techno-enhancements are in place, including Porsche Traction Management (PTM), Porsche Dynamic Chassis Control (PDDC), and Porsche Active Suspension Management (PASM). The PTM system is further enhanced by a transverse lock from the optional Offroad Technology Package available to regular customers, and the PDCC system is already set up with a Special Offroad Mode, which, when active, lets the Cayenne ford bodies of water up to 30″ deep. A roof-mounted snorkel keeps that water from invading the intake manifold.
