IROC XVII was the seventeenth year of IROC competition, which took place in 1993. It was the fourth and final year the Dodge Daytona was used in competition, and continued the format introduced in IROC VIII. Race one took place on the Daytona International Speedway, race two took place at Darlington Raceway, race three was held at Talladega Superspeedway, and race four ran at Michigan International Speedway. Davey Allison won the series championship posthumously after dying in a helicopter accident at the Talladega Superspeedway. With only one race remaining, Terry Labonte drove the final race, and the points from that race, applied to Allison's previous total, were enough to secure the championship. The winnings of $175,000 were placed in a trust fund for Allison's children. The roster of drivers and final points standings were as follows:
