If you've done autocross, you know that it can be a pretty intense 40-50 seconds during each run, so imagine what it is like to take a 45 sec AX course and go around 4 times without stopping - that's Endurocross.
Our local SCCA club holds an Endurocross every fall, and it's one of my favorite events. The course this year was a large figure-8 layout with a center cross-over, a couple of chicanes and a slalom. You get 2 runs of 4 laps each, and it is so strenuous, that I was nearly hyperventilating by the end of the runs (even my passenger in the first run was worn out), but it's a lot of fun.
On the first run, at the start of my 2nd lap (about 1 min. mark) I almost spin out (slippery corner, cold tires, PSM off) but manage to save it. In the second run I managed to shave about 1 1/2 sec off each lap.

PSM - Porsche Stability Management
While it can’t overcome the laws of physics, the revolutionary Porsche Stability Management (PSM) system does lend an added degree of balance and control to the Cayman’s mid-engine driving dynamics, inspiring surefooted confidence in corners and extreme situations.
A standard feature on the Cayman and Cayman S, PSM continuously monitors steering input, road speed, yaw velocity and lateral acceleration to calculate the actual direction of travel. If the car begins to steer off line, PSM instantly intervenes with precision brake inputs on individual wheels to help bring the car back onto the driver’s intended path.
If braking alone isn’t enough to correct the vehicle’s cornering line, PSM then calls on the Cayman’s engine management system, adjusting engine output as needed to help stabilize handling. PSM can also compensate in an instant for mid-corner changes in load resulting from deceleration or braking. When Sport mode is selected with the optional Sport Chrono Package, PSM’s threshold for intervention is raised, allowing for greater driver involvement. If you prefer driving without automatic PSM assistance, the system can be set to standby at any time. In this case, it will only intervene under heavy braking, where both front wheels exceed the ABS threshold.
For all of its technical ability, PSM goes virtually unnoticed in everyday driving situations, preserving the Cayman’s natural agility.
