I am looking for validation of what I think I know and a definitive way to know the car absolutely has the PTV option.
I am heading out this Saturday to test drive (and probably buy if I'm honest) a 2018 Cayman GTS. Needless to say, I am super excited ![]() My question is around the PTV. From what I have read, as a GTS it should have the Porsche Torque Vectoring option as a standard feature. However, there is nothing to prove that is does. (I have asked the dealer for a copy of the original window sticker, they say their system will only produce a spec sheet which doesn't list PTV. It doesn't list PASM either and I know that is there.). So let's assume that it does have PTV since it is a GTS. Next question is "Which PTV?". Is it the PTV or the PTV Plus? I read somewhere that since it has a PDK, it should have the PTV Plus. I have also read that as a Cayman, it has the standard PTV. Since the difference is in the way the differential locks, I will include this observation... the first time we looked at the car, it was on the rack being serviced so we could not drive it. While it was on the rack I was inspecting the CV boots and noticed that when I spun one wheel, the other moved in the opposite direction. This implies and unlocked differential (so no PTV). However, I learned that the diff is either mechanically locked (PTV) or electronically locked (PVT Plus), so in either case, the diff is unlocked most of the time. The means my observation of the wheel spin doesn't help me know if the car has PTV. I know I am bring up a question which has been answered, I hope you don't mind answering again to help me know what I am buying. THANKS!!!!
