So apparently some hot chick named Vicki can drift a AWD version where you can't get beyond the PSM in a rear wheel drive car. Apparently Stoppie could as well. Is the PSM in your country set differently?

In AMG cars you can turn it all OFF. But kicks in if the ABS needs to work.

PSM (early version) in Porsche is only OFF when pressed on a GT2 or GT3.
PASM (newer version & includes suspension) has SPORT and OFF.

Did you try leaving it pressed for a couple of seconds?

In this article by car magazine EVO - they notice that the PSM cuts in even when set to OFF - read halfway down

Porsch Panamera vs. Maserati Quattroporte vs. Jaguar XFR

My car is a US built Panny4S with Sport Chrono - no matter what mode your in, Regular, Sport or Sport PLUS, with the PSM OFF it still cuts the throttle and applies brakes once the slip angle limts are exceeded.

Before I return the car to Porsche for service work to correct this "FAULT" - based on the hearsay comments that say it is possible, will someone on this forum with access to a Panny actually do it and show it. Take out a Panny - any version - to an empty parking lot, initiate a drift and hold it. Shoot it with a cellphone and post the vid. Really easy.

So far everyone seems to be commenting on hearsay. Its obvious it can be bypassed completely as evidenced by the Camp 4 panny vid, but like the Winter Sporting AMG's these cars are specifically setup for the ice driving. In the case of the Winter Sporting AMG's they have a module that is plugged in to the wire harness attached to the ECU once you get to the Frozen lake - they do not let you bypasss the ESP on the public roads driving to the test facility.

Would really appreciate someone out there demonstrating that the US Pannys can hold the tail out - 'cos mine certainly wont

I have literally tried everything that I can - from decoupling fuses to unplugging wires, you name it, but PSM still intrudes.

Plesae note that
  • PSM = Porsche Stability Management and is what controls slip angle and many other things
  • PASM = Porsche Active Suspension Management and controls only the shock absorbers but is not wired into any circuits that cut throttle or apply any wheel braking and is not perinent to slip angle. PASM is what controls the supension modes - Comfort, Sport, Sport Plus. It is sected by the shockabsorber icon on the tunnel console
  • MODE = When you select "Sport" or "Sport Plus" mode from the SPORT and SPORT PLUS selectors on the tunnel console, they apply settings to the PASM (suspension), and to the PDK (trasnmission) to have faster more abrupt shifts at higher shift points. It also sets PSM to intervene later (higher slip angle), and the spoiler extends earlier and retracts later. Sport Plus also stops the use of 7th gear. It also has an effect on Turbo boost - not applicable to my car.

So please note that there is a difference between Sport /Sport Plus and PASM Sport /PASM Sport Plus. You can set supsension PASM to Sport Plus and still be in regular mode - regular shift points etc.

I know, I mean since PSM + PASM is available includes a Sport mode replaces the early PSM with just ON / OFF (finally not completely), for ON / Sport / OFF.

Could it be your driving?
You don't carry a Yaw Angle Whojamabober with you?? 11.499 she is sliding.
