NASCAR Whelen Euro Series was initially scheduled to be hosting NASCAR's first event on ice with the NASCAR Arctic Ice Race, which was initially scheduled to open the season as an exhibition event on 4–5 March. The announcement follows upon what NASCAR Whelen Euro Series had announced last year where the series plans to host a non-championship Winter Classic event at some point between late 2022 and early 2023. However, on 10 January 2023 it was announced that the race was postponed indefinitely due to global supply chain issues. Had the NASCAR Arctic Ice Race went underway, the race would use the following format that was first announced on 3 December 2022:
Six 30-minute long free practice sessions was planned to be held on Friday on a 3.2 km (2.0 mi) long track.
A Time Attack tournament was planned to be held on a 2.4 km (1.5 mi) track layout on Saturday, with the results of the tournament determined the starting grid for Sunday's event.
A rallycross-style shootout event was planned to be held on Sunday on a 2.0 km (1.2 mi) layout of the track. The shootout would include heat races, semi-finals and finals to determine the overall winner of the event.
