Autocross – Lone Star Porsche Club


What is Autocross?

Autocross (or AX) is an entry level competitive driving event around a course defined by traffic cones. Each “lap” is individually timed for each driver. There is no “wheel-to-wheel” competition with courses designed to be negotiated entirely in 2nd gear for most vehicles. A typical course is 45 to 60 seconds long.

Autocross gives you the opportunity to develop your car control skills in a relatively safe environment.

PCA National Autocross rules allow for any licensed driver age 16 or older to participate in Autocrossing.

Beginner PCA members are always welcome, and there are no prerequisites other than arriving with a vehicle in safe working condition. We require non-member entrants to be experienced to allow instructors to focus on PCA member beginners.

Up to two drivers can share a single vehicle allowing for multiple family members to participate.
