The HPD ARX-03 made its racing debut at the 2012 12 Hours of Sebring. The race would be the opening round of both the American Le Mans Series and the brand new FIA World Endurance Championship seasons. Muscle Milk Pickett Racing campaign a brand new ARX-03a LMP1 car, while Level 5 Motorsports campaigned two LMP2 ARX-03bs in the American Le Mans Series. After some bad luck with a fueling hose at Sebring, the Muscle Milk team went on to win the next five races in a row as well as another win at Virginia International Raceway. At the seasons final race, Petit Le Mans, Lucas Luhr was hit by a GTC class Porsche. Despite repairs needed during the race, the team was able to complete 70% of the race in order to win points. Muscle Milk Pickett Racing won both the LMP1 drivers and team championships with just 5 points over their main rivals, Dyson Racing. The Level 5 Motorsports team took first in class at the Mobil 1 12 Hours of Sebring and went on to win 7 of the next 9 races, losing only at Mosport and Road America to their main rivals, Conquest Endurance. The team was able to secure the LMP2 Teams' Championship and Drivers' Championships.
Strakka Racing, JRM and Starworks Motorsport would contest the first series of the brand new FIA World Endurance Championship. The Starworks team would claim three class victories including the season opening 12 Hours of Sebring and the 24 Hours of Le Mans and claim the LMP2 trophy with their HPD ARX-03b. Strakka Racing and JRM, competing with ARX-03a's, would finish second and third in the LMP1 Privateer Trophy behind the Swiss Rebellion Racing squad with Strakka racing claiming just one class victory.
