I picked up my new '09 2.9 on Saturday and will provide details and pictures after a little more driving. However, on the window sales sticker I noticed it listed ASR - Anti Slip Regulation under "Standard Equipment" below ABS and above EDTC (engine drag torque control). Is this a new feature for the V2 and if so, how does it work? Is it a form of LSD?
PS - Needless to say, I am loving the car.
Standard Porsche Stability Management uses a range of sensors and Automatic Brake Differential and Anti-Slip Regulation to maintain traction and stability. So many buuzwords and so little time.

The window sticker on my new 2.9 lists ASR - Anti Slip Regulation as standard equipment. Does anyone know what this is or if it's a type of LSD?
Thanks.
Threads merged - please don't start new threads in a different forum on the same exact subject. thanks

From Porsche "PSM, which comes as standard, is an automatic control system that stabilises the vehicle at the limits of dynamic driving performance. Sensors continuously monitor driving direction, speed, yaw velocity and lateral acceleration. Using this information, PSM computes the actual direction of motion. If this direction deviates from the desired course, PSM initiates braking interventions targeted at individual wheels in order to stabilise the vehicle.
Under acceleration on wet or low-grip road surfaces, PSM improves traction using the ABD (automatic brake differential) and
ASR (anti-slip regulation) functions
, giving an agile response. When ‘Sport’ mode is selected on the optional Sport Chrono Packages, the PSM intervention threshold is raised to enable greater driver involvement – particularly at speeds of up to approximately 70 km/h (45 mph). The integrated ABS can further reduce the braking distance. For an even sportier drive, PSM can be deactivated. However, it is automatically reactivated for your safety if either of the front wheels (in ‘Sport’ mode, both of the front wheels) requires ABS assistance. ABD remains permanently active. PSM has been enhanced and now includes two additional functions: precharging of the brake system, and brake assist. If you suddenly release the accelerator pedal, PSM automatically readies the braking system. With the braking system having been precharged, the brake pads are already in light contact with the brake discs. Maximum braking power is therefore achieved much sooner. When sudden braking is detected, the brake assist function applies maximum brake pressure to all four wheels." This is something the sales person should have explained when you were doing your shopping due diligence.
