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 [[List of USAC Championship Car seasons|United States National Championship]], and from 1956 to 1997 the organization sanctioned the [[Indianapolis 500]]. USAC serves as the [[sport governing body|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 [[GT World Challenge America]]. Seven-time USAC champion Levi Jones is USAC's Competition Director.<ref>{{cite news |title=Rip the Fence: Episode 60 - Levi Jones |url=https://www.mrn.com/shows/rip-the-fence-episode-60/ |access-date=September 18, 2021 |work=[[Motor Racing Network]]}}</ref>

For a while there was a separate series of specifications for championship cars designed to be run on dirt, rather than paved, tracks. Today, USAC sanction [[open-wheel racing]] series such as the Silver Crown Series, [[Sprint car racing|National Sprint Car Series]], [[Midget car racing|National Midget Series]], and [[Quarter Midget racing|Quarter Midgets]].
===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. Six other drivers, [[Pancho Carter]] (1972–78), [[Dave Darland]] (1997–2001), [[Jerry Coons Jr.]] (2006–08), [[Tracy Hines]] (2000, 2002, 2015), [[Chris Windom]] (2016, 2017, 2020), and [[Logan Seavey]] (2023-2024) 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.{{citation needed|date= October 2022}}

USAC awarded a national championship until [[A. J. Foyt]] won his seventh title in 1979.<ref name="NSSNFeb232010">{{cite web|url=http://www.nationalspeedsportnews.com/node.php?tag=15&id=2604 |title=A True USAC National Championship |last=Waltz |first=Keith |date=February 23, 2010 |publisher=[[National Speed Sport News]] |access-date=31 March 2010 |url-status=dead |archive-url=https://web.archive.org/web/20100417111915/http://www.nationalspeedsportnews.com/node.php?tag=15 |archive-date=April 17, 2010 }}</ref> It resumed awarding a national championship in 2010.<ref name="NSSNFeb232010" /> A driver's best 25 finishes are counted toward the championship and the 2010 winner received $40,000.<ref name="NSSNFeb232010" /> Points are accumulated in the three national series: sprints, midgets, and silver crown.<ref name="NSSNFeb232010" /> [[Bryan Clauson]] of [[Noblesville, Indiana]] claimed the inaugural championship, topping runner-up Levi Jones by 14 points.

The incident closely followed the death of Indianapolis Motor Speedway owner Tony Hulman.<ref name="Star04-25-1978pg9" />
===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.<ref>[http://www.automedia.com/IRL_and_CART/pht20030901ic/1 The battles wage on and off the tracks] {{Webarchive|url=https://web.archive.org/web/20090614155527/http://www.automedia.com/IRL_and_CART/pht20030901ic/1 |date=2009-06-14 }} ''automedia.com.''</ref> 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,<ref>''[[Donald Davidson (historian)|The Talk of Gasoline Alley]]'' - [[WIBC (FM)|1070-AM WIBC]], May 10, 2007</ref> 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.<ref>[http://oreopolis.com/Pages/051401.html The CART-USAC War: part 1] {{Webarchive|url=https://web.archive.org/web/20070928205558/http://oreopolis.com/Pages/051401.html |date=2007-09-28 }} ''oreopolis.com. Originally published in NUVO Newsweekly – January 25, 1996.''</ref>
Finally, most car owners banded together to form [[Championship Auto Racing Teams]] (CART) in 1978, with the first race to be run in [[1979 IndyCar season|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 multi-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 (CRL) 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.<ref>[http://oreopolis.com/Pages/051501.html The CART-USAC War: part 2] {{Webarchive|url=https://web.archive.org/web/20070928205553/http://oreopolis.com/Pages/051501.html |date=2007-09-28 }} ''oreopolis.com. Originally published in NUVO Newsweekly – January 25, 1996.''</ref> After USAC's attempt at a 500-mile race 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 no other Championship car races, and CART including the race in its schedule between other CART-sanctioned races. 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 [[1997 Indianapolis 500|two consecutive]] [[1997 True Value 500|officiating controversies]] that year; subsequent Indy 500s (and IRL races, as USAC was also involved in IRL's racing-related matters up to that point) were sanctioned by the IRL itself, which was renamed the IndyCar Series in 2003.
===Road racing expansion===
Since 2022, the United States Auto Club has sanctioned the [[USF Juniors]], [[USF2000 Championship]], and [[USF Pro 2000 Championship]] series, which serve as a ladder series to Indy NXT, along with the [[Radical Sportscars]] North American Championships, [[Skip Barber Racing School]], as well as continued sanctioning of the [[GT World Challenge America]] and [[Porsche Sprint Challenge North America]] under the newly formed Road Racing Division under the direction of [[Randy Hembrey]].

=== 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 Motor Company|Ford]] supplying their [[Ford Zetec engine|Zetec engine]] from 2002 to 2012, and then [[Honda Performance Development|HPD]] supplying their [[Honda K engine#K24|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.

===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 [[Championship Auto Racing Teams|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 with the advent of the [[IndyCar|Indy Racing League]].
