NASCAR's premier racing division, the NASCAR Cup Series, has seen many close finishes since the electronic scoring system was instituted in May during the 1993 season. As of 2022, the closest margin of victory in the NASCAR Cup Series is 0.002 seconds. This first occurred during the 2003 Carolina Dodge Dealers 400 at Darlington Raceway, as Ricky Craven crossed the finish line inches ahead of Kurt Busch.
