IROC XX was the twentieth season of IROC competition, which started on February 16, 1996. It was the first year that the Pontiac Firebird Trans Am was used in competition, and contested races at Daytona International Speedway, Talladega Superspeedway, Charlotte Motor Speedway, and Michigan International Speedway. Mark Martin won the first night race in the history of the series in race three at Charlotte Motor Speedway, and won again in the season finale at Michigan International Speedway to win $225,000 in a come-from-behind IROC championship, his second in three seasons.
