The 2015 Oak Tree Grand Prix was a sports car race sanctioned by the International Motor Sports Association (IMSA). The Race was held at Virginia International Raceway in Alton, Virginia on August 23, 2015. The race was the tenth round of the 2015 United SportsCar Championship.
Background
Preview International Motor Sports Association (IMSA) president Scott Atherton confirmed the race was part of the schedule for the 2015 IMSA Tudor United SportsCar Championship (IMSA TUSC) in August 2014. It was the second consecutive year the event was held as part of the United SportsCar Championship. The 2015 Oak Tree Grand Prix was the tenth of twelve scheduled sports car races of 2015 by IMSA, and was the seventh round not held as part of the North American Endurance Cup. The race was held at the seventeen-turn Virginia International Raceway in Alton, Virginia on August 23, 2015. The PC category was dropped from the event.
Entry list Eighteen cars were officially entered for the Oak Tree Grand Prix, with most of the entries being in the Grand Touring Daytona (GTD) category. GTLM was represented by eight entries from four different brands. In the list of GTD entrants, ten GT-specification vehicles were represented by six different manufacturers. With the absence of the Prototype (P) and Prototype Challenge (PC) classes from the field, only two racing classes were represented in Virginia International Raceway.
Qualifying Saturday afternoon's 40-minute two-group qualifying session gave 15-minute sessions to all categories. Cars in GTD were sent out first before those grouped in GTLM had a separate identically timed session. Regulations stipulated teams to nominate one qualifying driver, with the fastest laps determining each class starting order. IMSA would arrange the grid to put all GTLMs ahead of the GTD cars.
