The Sports Car Club of America (SCCA) is a club and sanctioning body supporting road racing, rally, and autocross in the United States and was formed in 1944. It runs many different programs for both amateur and professional racers.

Club racing

The club racing program is the road racing division where drivers race wheel-to-wheel on either dedicated race tracks or on temporary street circuits. Competitors require either a regional or a national racing license. Both modified production cars (ranging from lightly-modified cars with only extra safety equipment to heavily-modified cars that retain only the basic shape of the original vehicle) and designed-from-scratch "formula" and "sports racer" cars can be used in club racing.

Most of the participants in the Club Racing program are unpaid amateurs, but some go on to professional racing careers. The club is also the source for race workers in all specialties, without whom racing organization and operation would not be possible.

The annual National Championship for Club Racing is called the "Runoffs" and has been historically held at Riverside International Raceway (1964, 1966, 1968), Daytona International Speedway (1965, 1967, 1969), Road Atlanta (1970-1993) and Mid-Ohio Sports Car Course (1994-2005). In 2006, the "Runoffs" moved to Heartland Park Topeka. Beginning in 2009 the Runoffs will be held at Road America in Elkhart Lake, Wisconsin for a minimum of three years. The current SCCA record holder is Jerry Hansen with 27 titles. Hansen is the father of TLC and Spike TV television personality and author Courtney Hansen.

Autocross

The Solo program is the autocross program. One car at a time, running a course laid out with traffic cones on a large paved surface, such as a parking lot or airport runway.

Competitions are held at the Regional, Divisional, National, and Pro levels. Each Division typically crowns a Divisional Champion in each class, awarded by winning a single event. Similarly, a National Champion in each class is awarded by winning the class at the National Championship (usually referred to as "Nationals") held in September. 2006 ushers in a new site for The Solo National Championship, replacing Forbes Field with the newly renovated Heartland Park Topeka in Topeka, Kansas. Individual National-level events, called "National Tours", are held throughout the racing season.

The professional autocross series, called ProSolo, runs two cars at a time on mirror-image courses and features a drag racing style "Christmas tree" start, complete with reaction times and 60' times. Class winners and other qualifiers (based on time differential against the class winner) then compete in a handicapped elimination round called the "Challenge". Points are awarded both in class competition and in Challenge competition, and an annual champion is crowned each September at the Pro Finale event in Topeka, Kansas
