Straightline

If you recall, last year Porsche developed a special Cayenne to compete in the 4,400 mile Moscow-to-Mongolia Transsyberia Rally. Now they've come up with a new-and-improved version for this year's race.

Improvements over last year's racer include a new sump guard, a beefier tire package, tweaked air suspension, a shorter final drive ratio (shared with the new Cayenne GTS), plus updates to the transmission programming, dynamic chassis control and traction management systems. Also, an upgrade conversion package is available for those who own last year's model.
