After being a part of the SCCA National Sports Car Championship and the IMSA GT Championship the race, along with the track, went on hiatus from the early 1970s until 2002.

In 2014 the race joined the schedule of the United SportsCar Championship after the merger of the American Le Mans Series and the Rolex Sports Car Series.

The former title VIR 240 refers to the duration of 240 minutes (4 hours).

In 2013, the race was renamed the Oak Tree Grand Prix.

[1] Beginning in 2016, the Oak Tree Grand Prix became the name of the Continental Tire SportsCar Challenge support race run on the same weekend as the United SportsCar Championship Michelin GT Challenge at VIR.
