HPD debuted in the CART IndyCar World Series as a works engine manufacturer in 1994. Although the engines were not competitive at first, they scored a podium in 1994 at Toronto, followed by their first victory at New Hampshire in 1995. In 1996, HPD won its first manufacturers' and drivers' championships after taking 11 wins from 16 races. HPD took six consecutive drivers championships' as it won the drivers' title again in 1997, 1998, 1999, 2000 and 2001, while it won the manufacturers' title again in 1998, 1999 and 2001. In 2003, HPD moved to the IRL IndyCar Series. In 2004, HPD overwhelmingly dominated the IndyCar Series by winning 14 of 16 races, including the Indianapolis 500, and claiming the manufacturers' and drivers' championship titles. The 2005 season was similarly successful as the company took its second Indy 500 victory and won 12 races to win the manufacturers' and drivers' crowns. From 2006 to 2011, HPD was the sole engine manufacturer of the IndyCar Series, including the Indianapolis 500. During this period, the Indianapolis 500s were ran without any engine failures for the first six times in Indy 500 history, while no race failures occurred in the entire 2008, 2010 and 2011 seasons. Manufacturer competition returned to the series in 2012, and HPD has constructed turbocharged V6 engines for its effort. Since then, HPD has won the Indianapolis 500 in 2012, 2014, 2016 and 2017, the drivers' championship in 2013 and 2018, and the manufacturers' championship in 2018 and 2019.
In 2006, Honda through its Acura brand, announced their plans to develop a Le Mans Prototype program for the ALMS, competing in the LMP2 class for the initial year of competition in 2007. The new car, called Acura ARX-01a, was a homologated development of chassis from Courage with a new 3.4 liter V8, the maximum size allowed by the rules being developed by HPD. This was the first V8 ever branded as an Acura as well as the first racing Honda engine built entirely outside Japan. Elements of the Acura V8, dubbed the AL7R, share similar architecture with the Honda engine used in the Indy Racing League although none of the parts are interchangeable. In 2010 Honda dropped the Acura name in favour of HPD and the car is now known as the HPD ARX-01.
In 2007, HPD supplies Vemac RD320R and Vemac RD408R for GT300 cars in Super GT Series with designation C32B. For the 2012 racing season HPD decided to forgo having a works team and instead focus on being a chassis and engine provider. 2012 also saw HPD return to the premier class of racing, LMP1, in the Le Mans and FIA World Endurance Championship series. ;FIA World Endurance Championship

For 2018, HPD will return to the Prototype class of the IMSA SportsCar Championship, as the ARX-05 will compete at the IMSA SportsCar Championship with technical support from HPD.
