Then International Motor Sports Association's (IMSA) president Scott Atherton confirmed the race was part of the schedule for the 2020 IMSA SportsCar Championship (IMSA SCC) in August 2019.[2] It was the seventh consecutive year it was part of the IMSA SCC. The Michelin GT Challenge at VIR was the fifth of eleven sports car races of 2020 by IMSA, and the fourth of seven races on the WeatherTech Sprint Cup.[3] The race was held at the 3.270 mi (5.263 km) Virginia International Raceway on August 22, 2020.[4] Much like in previous years, the event was a GT only round, in which the GTLM and GTD classes were scheduled to compete.[5] Due to a clash with the Indianapolis 500, the event was moved from August 23, 2020, to August 22, 2020.[6]
Due to Virginia's COVID-19 gathering restrictions, fans were barred from attendance for the first time this season.[7] The previous three rounds had limited attendance, but the VIR round was the first to outright prevent any fans from entering the grounds. Patrick Pilet and Nick Tandy entered the race as defending champions, although only Tandy participated in the 2020 iteration.[8]
On August 14, 2020, IMSA released the latest technical bulleting, outlining the BoP for the race.[9] In GTLM, the BMW M8 GTE received a five kilogram weight reduction, while the Corvette and Porsche received 20 kilogram weight increases. The Porsche also received a five-liter fuel capacity increase. In GTD, the Audi received a 20 kilogram weight reduction, while the Lexus (which had won the previous three events) had 15 kilograms of ballast added to its total weight.
A total of 20 cars took part in the event, split across two classes. 6 were entered in GTLM, while 14 were entered in GTD.[11] The lone change from the previous round was the return of Paul Miller Racing's Lamborghini Huracan, which had been absent since the opening race at Daytona.[12]
Practice
There were two practice sessions preceding the start of the race on Saturday, both on Friday. The first session lasted one hour on Friday morning while the second session lasted 75 minutes on Friday afternoon.[13]
The second and final practice session took place at 12:00 pm ET on Friday and ended with Oliver Gavin topping the charts for Corvette Racing, with a lap time of 2:03.700.[19]Aaron Telitz set the fastest time in GTD.[19] Twelve of the twenty entries did not get a time in due to heavy rain.[19]
Friday's afternoon qualifying was broken into two sessions, with one session for the GTLM and GTD classes, which lasted for 15 minutes each, and a ten minute interval between the sessions.[13] The rules dictated that all teams nominated a driver to qualify their cars, with the Pro-Am (GTD) class requiring a Bronze/Silver Rated Driver to qualify the car. The competitors' fastest lap times determined the starting order. IMSA then arranged the grid to put the GTLMs ahead of the GTD cars.[22]
