What is autocross?
Autocross is a sport where you try to drive around a course in the shortest possible time. The course is laid out at our wonderful site at the Sonoma County Airport and outlined by orange plastic cones. Every run is timed electronically and time is added for each cone tipped over. You can measure your progress throughout the day, and possibly earn bragging rights. We emphasize safety, fun and speed. This is probably the safest and least expensive way to drive your Porsche at the limit.

Autocross is also a driver education class. If you are completely new to autocrossing we have qualified instructors available at each event at no charge. We also have loaner helmets available.

For those of you who are interested in autocross, but not sure if you want to give it a try, we offer "A Taste of the Autocross", where for $5 we will put you in a car with one of our instructors and let you ride along for a couple of runs. The money goes to our charity, Sonoma CASA.

Autocross is a great way to:
Learn how to handle your Porsche
Drive your Porsche the way it was meant to be driven
Make new friends
See "old" friends
Spend time with your significant other doing something fun
