SCCA Pro Racing

Current championships

As of 2011, SCCA Pro Racing sanctions the F1600 Championship Series, a Formula Ford-based class that permits the Honda Fit engine alongside the Ford Kent engine. For 2012, it sanctioned the revived Atlantic Championship, which ran under SCCA Formula Atlantic rules, allowing older Toyota-engined cars and newer Mazda-engined cars; the class was put on hold for 2013 and returned in 2014. SCCA Pro Racing sanctioned the Trans-Am Series from its 1966 inception until its 2006 folding; the series was revived in 2009, allowing SCCA GT1 cars in a national series, with SCCA Pro Racing continuing as sanctioning body.

Management transferred to the Trans Am Race Company, LLC in 2011, but SCCA Pro Racing still sanctions events and provides contracted operations. In January 2017, a 25-year agreement renewed the partnership. Since 2012, SCCA GT1, GT2, and GT3 cars are allowed. The Formula Regional Americas Championship powered by Honda, an FIA Formula 3 series competing in the United States with plans for Canada and Mexico, is sanctioned by SCCA Pro Racing in conjunction with ACCUS.

Starting in 2020, the champion earned a scholarship to compete in Indy Lights. In 2019, SCCA Pro Racing regained the rights to the three Formula Race Promotions series, which had been sanctioned by USAC for 2017 and 2018.

Previous championships

Between 1963–1968 and 1998–1999, SCCA Pro Racing organized the USRRC, initially for open sports cars and GTs. The series was dropped in 1968 in favor of Can-Am, which was then called USRRC; Can-Am folded in 1986. The USRRC was revived for two years in the late 1990s, and after 1999 the organization was taken over by Grand-Am. The Can-Am championship was a joint venture between the Canadian CASC and the American SCCA, starting in 1966 as a sports car championship; by its end in 1986 it used converted Formula 5000 cars.

The SCCA Grand Prix Championship began in 1967, initially permitting SCCA Formula A, B, and C cars; from 1968, cars with 5-liter production-based V8 engines (later known as Formula 5000) were allowed. The series folded in 1976 but continued in the single-seat Can-Am series. A spec touring car series for the first-generation Volkswagen Scirocco started in 1976, the first pro spec touring series. In 1979, SCCA sanctioned the first CART season because CART was not recognized by ACCUS; after that season, CART took over sanctioning.

A city-based team concept similar to A1GP ran primarily on the west coast. The Corvette Challenge, a spec series for the Chevrolet Corvette (C4), existed in 1988 and 1989, formed after Corvettes were excluded from World Challenge; cars were readmitted in 1990. The RaceTruck Challenge for pickups such as the Jeep Comanche, Ford Ranger, and Dodge D-50 ran from 1987 to 1991. The SCCA American Continental Championship and USAC Formula 2000 merged in 1995 to form the U.S. F2000 National Championship, which folded in 2006 and was revived by Mazda Road to Indy in 2010.

A short-lived sports car class ran from 1991 to 1996, also featured at the Runoffs; after folding, its cars were allowed in the C Sports Racer class.
