New Cayenne Turbo S is caught mostly undisguised sporting some new aerodynamic parts.

These are the first spy shots of the upcoming 2012 Porsche Cayenne Turbo S, caught almost completely undisguised while out for some testing on and around the Nürburgring Nordschleife in Germany.

The only differences we spotted from the Cayenne Turbo are the slightly more aerodynamic side skirts and a peculiar rectangular panel hanging from the rear diffuser.

This Cayenne Turbo S will be more powerful than its predecessor, given that the Cayenne Turbo itself just got bumped up to 540 PS (397 kW / 535 bhp) and 750 Nm of torque from the previous 500 PS.

But we will have to wait and see what those final numbers are.
