United States Auto Club

The United States Auto Club (USAC) is one of the sanctioning bodies of auto racing in the United States. From 1956 to 1979, USAC sanctioned the United States National Championship, and from 1956 to 1997 the organization sanctioned the Indianapolis 500. Today, USAC serves as the sanctioning body for a number of racing series, including the Silver Crown Series, National Sprint Cars, National Midgets, Speed2 Midget Series, .25 Midget Series, Stadium Super Trucks, , and Pirelli World Challenge.
History.
When the American Automobile Association (AAA) withdrew from auto racing after the 1955 season, citing the Le Mans disaster and the death of Bill Vukovich at Indianapolis as contributing factors, both the SCCA and NASCAR were mentioned as its potential successor. Ultimately, USAC was formed by Indianapolis Motor Speedway owner Tony Hulman. It became the arbiter of rules, car design, and other matters for what it termed championship auto racing, the highest level of USAC racing. For a while there was a separate series of specifications for championship cars designed to be run on dirt, rather than paved, tracks.
USAC's long history as an open-wheel racing sanctioning body continues today with the Silver Crown Series, National Sprint Car Series, National Midget Series, Ignite Ethanol Fuel Series, Quarter Midgets, and . NASCAR drivers including Jeff Gordon, Tony Stewart, Ryan Newman, and Kasey Kahne honed their skills and captured championships while competing in various USAC series.
Triple crown.
The "triple crown" is earned in USAC racing when a driver claims all three national championships (silver crown, sprint car, and midget car). Only two drivers, Tony Stewart (1995) and J. J. Yeley (2003), have achieved the triple crown in a single season. Five other drivers, Pancho Carter (1972–78), Dave Darland (1997–2001), Jerry Coons Jr. (2006–08), Tracy Hines (2000, 2002, 2015), and Chris Windom (2016, 2017, 2020) have claimed each of the three championships at least once in their careers. In 2012 Mike Curb and Cary Agajanian became the only car owners to win the triple crown by winning all three championships in the same year.
National championship.
USAC had awarded a national championship until A. J. Foyt won his seventh title in 1979. It has announced that it will begin awarding a national championship starting in 2010. A driver's finishes in their 25 best races are counted toward the championship and the 2010 winner received $40,000. Points are accumulated in the three national series: sprints, midgets, and silver crown. Bryan Clauson of Noblesville, Indiana claimed the inaugural championship, topping runner-up Levi Jones by 14 points.
As of 2013 it has been known as the Mike Curb "Super License" National Championship Award.

1978 plane crash.
On April 23, 1978, returning from a race at the Trenton Speedway in New Jersey, eight USAC officials, plus the pilot, were killed when their 10-seat Piper Navajo Chieftain crashed during a thunderstorm 25 miles southeast of Indianapolis.
Killed were:
The effect on USAC, and for open-wheel racing in the United States, was devastating, especially since it closely followed the death of Indianapolis Motor Speedway owner Tony Hulman.
End of championship car sanctioning.
The plane crash came at a time when Indy car owners and drivers were demanding changes from USAC. Aside from the Indianapolis 500, USAC events were not well attended, and the owners felt that USAC poorly negotiated television rights. The owners also wanted increases in payouts, especially at Indy. Though some think the plane crash was used as an opportunistic way to force change in the sport, it was merely an unfortunate coincidence. The seed of dissent had been growing for several years before the accident, and claims the crash was an immediate cause for the 1979 CART/USAC "split" are considered for the most part unfounded.
Also unpopular were the attempts of USAC to keep the aging Offenhauser engine competitive with the newer, and much more expensive, Cosworth DFX engine using boost-limiting "pop off valves" and limiting the amount of fuel that could be used.
Finally, most car owners banded together to form Championship Auto Racing Teams (CART) in 1978, with the first race to be run in 1979. USAC tried unsuccessfully to ban all CART owners from the 1979 Indianapolis 500, finally losing in court before the race began. Both the USAC and CART ran race schedules in 1979.
Indianapolis Motor Speedway president John Cooper was instrumental in forming a joint body of CART and USAC with the creation of the Championship Racing League in March 1980. However, in mid 1980, Cooper forced USAC to renounce their agreement with the CRL if they wanted to keep officiating the Indy 500. After USAC's attempt at a 500-mile races at Pocono Raceway – which was boycotted by the CART teams, forcing USAC to fill the field with silver crown cars – USAC and CART eventually settled into a relatively peaceful co-existence, with USAC continuing to sanction the Indianapolis 500, and CART including the race in its schedule. USAC continued to sanction the Indy 500 until 1997, when the Indy Racing League (itself product of the second American open-wheel split in 1996) terminated the sanctioning agreement following two consecutive scoring errors that year; subsequent Indy 500s were sanctioned by the IRL, now the IndyCar Series.
Active series.

USAC 360 Sprint Car Series.
USAC sanctions several regional 360 c.i.d. non-wing sprint car series across the country.

USAC and URC Sprint Caf Series promoter Curt Michael joined forces to create the USAC East Coast Sprint Car Series, with the first season beginning in 2018.
Champions
USAC Speed2 Midget Series.
USAC formed the Speed2 Midget Series (formerly known as the Ford Focus Midget Series, Ignite Midget Series and HPD Midget Series) in 2002 with several regional divisions running across the United States on both dirt & pavement oval tracks. With exception to the engine, the cars used are the same as National & Western States Midget cars. The powerplants currently used are 4-cylinder production-based engines with stock internal dimensions to save costs for competitors. The series started out as a spec engine class, originally with Ford supplying their Zetec engine from 2002-2012, and then HPD supplying their K24 engine starting in 2013.
National Championship
The Speed2 Midget Series National Champion has been determined in a variety of ways. The inaugural championship, 2005, was decided by a two-race series (one dirt, one pavement). Subsequent national champions were determined by a single "national championship race" held at various locations. This format was used until 2010. In 2011, a points system was instituted to determine the national champion. Counting only a drivers twelve best finishes, the system allowed drivers from multiple regions to compete under a common points structure for a season-long championship. The 2012 season did not award a national champion, however the respective regional champions were honored at USAC Night of Champions.

Former series.
USAC Gold Crown Series.
Starting in 1981, USAC scaled back their participation in Indy car racing outside of the Indianapolis 500. The preeminent national championship season was instead being sanctioned by CART. USAC developed a split-calendar season, beginning in June, and ending in May with the Indy 500. After 1983, however, the Gold Crown schedule would consist of only one event per season (Indy 500), and the Gold Crown title would be regarded largely as ceremonial. The winner of the Indianapolis 500 would be the "de facto" Gold Crown champion, as it was the lone points-paying event. The title and the "series" were retired after the 1994–1995 season.
USAC Stock Cars.
USAC featured a stock car division from 1956 to 1984.
USAC Road Racing Championship.
