About: American autocross

American autocross is a form of autocross, an individual motorsport in which drivers compete to set the fastest time on a temporary course. Events are usually held on large paved areas, such as parking lots or airfields. Courses consist of turns, offsets, and slaloms marked by traffic cones; new courses are typically created for each event. The Sports Car Club of America (SCCA) is the largest autocross sanctioning body in the United States; the National Auto Sport Association (NASA) and various manufacturer-affiliated and independent clubs also hold events.
