Does anyone know whether the 2013 Cayenne GTS has a limited slip differential for the rear wheels as standard? or, there is none unless PTV Plus is ordered? Thanks!

 

According to Porsche, standard drive and suspension features on the 2013 GTS include:
*All wheel drive
*PSM (Porsche Stability Management), with ABS (Anti lock Braking System), ASR (Anti Slip Regulation), ABD (Automatic Brake Differential), and EDTC (Engine Drag Torque Control).
*Porsche Traction Management (PTM): Active all-wheel drive with electronic and map-controlled multiplate clutch with automatic brake differential (ABD) and antislip regulation (ASR)
*Air Suspension with self-leveling/height adjustment and PASM (-20mm)

So I'd have to say that the GTS has left the old limited slip differential days in the dust. FWIW, this page doesn't even indicate that PTV is available on the GTS. That said, I didn't bother to "build" one to verify the accuracy of that page.
