History
The series was founded in 1972 by Glenn Donnelly as a series of qualifier races for the inaugural Super Dirt Week at the New York State Fairgrounds Racetrack in Syracuse, New York. The series became a true points championship in 1974 that also awarded a points fund. Will Cagle won the first points championship in 1974 over two-time Super DIRT Week champion Buzzie Reutimann.

The series and Super Dirt Week grew in popularity along with corporate title sponsors & television coverage throughout the 1980s and 1990s. Past series title sponsors include Schaefer Beer (1972–1975 and 1978), CRC Industries (1979–1985), Sun Country Cooler (1986), U.S. Smokeless Tobacco Company (1987–1998) and Advance Auto Parts (1999–2008).

The series briefly included asphalt races on the championship trail from 1988 to 1992 at tracks such as Cayuga, Flemington, Nazareth, Oswego, Sanair and Thompson.

The series was acquired by World Racing Group (then Boundless Motorsports) in 2003.

The crown jewel event of the series, Super Dirt Week had to changed venues for the first time in 2016 to a dirt-covered Oswego Speedway in Oswego, New York following the demise & razing of the New York State Fairgrounds Racetrack.

Mr. DIRTcar
Beginning with the 1980 season points earned in the Super DIRTcar Series were credited toward crowning an overall Mr. DIRTcar champion. Over the years, a variety of formulas have been used, and included bonus points for feature wins and/or seasonal standings at weekly home tracks. In 2000, the two series were merged. Beginning in 2011, the Mr. DIRTcar championship was separated and decided only on a driver's best 16 finishes at their weekly home track.
