of 2017 most nationals competitors were running the 016.a-Mazda combination. Also eligible for the class are Mazda rotary powered cars made for the Pro Mazda Championship. In 2018 the professional series will switch to a new car and all of the rotary cars will be available for club racing use, although they appear to not be competitive with cars built to the FA specification, even older ones. Additionally, in 2019 the SCCA will allowed sealed Mazda MZR engines to be used in older chassis, such as the Swift 014.a, as parts availability for the Toyota engines has become an issue. The minimum weight of a Toyota or BDD powered Atlantic car is 1230 lbs. (558 kg) with driver. The SCCA considers it its fastest club racing class. Prior to gaining its own class, the Formula SCCA car raced in Formula Atlantic, where it was uncompetitive. Revived Atlantic Championship With the end of the IMSA and Champ Car sanctioned professional Atlantic Championship after the 2009 season, the promoters of the F2000 Championship Series, Formula Race Productions, promoted a new pro series in 2012 using SCCA rules and sanctioned by the SCCA. The series saw few entrants and folded after one season. However, due to increasing interest at the amateur level, on October 1, 2013, it was announced that the series would return in 2014 with a twelve race, six weekend race calendar. Sanctioning will transition to the United States Auto Club in 2017. Tribute In 2012 and 2014, the Rolex Monterey Motorsports Reunion historic automobile racing event at Mazda Raceway Laguna Seca in Monterey, California had a tribute to Formula Atlantic as a part of its scheduled groups.
