レベリオン・レーシング
For 2013, the team continued competition with their HPD ARX-03a for the first three rounds before moving to the updated -03c for the remainder of the season. For the first three races, the team faced serious competition from the Swiss Rebellion Racing team. After losing out at the season opening 12 Hours of Sebring the team claimed the next two races at Long Beach and Laguna Seca. With Rebellion Racing withdrawing their full season entry to focus on 2014 plans, the Muscle Milk team won the next six races over the Dyson Racing squad and claimed the Teams' and Drivers' Championships. Rebellion Racing returned for Petit Le Mans, the final race of the American Le Mans Series before it would merge with the Rolex Sports Car Series to form the new United SportsCar Championship. A rain filled race saw the team lead overall until an overheating issue took the team's HPD out of the race.
