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 motor built entirely in the United States by Honda. 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.
For the 2012 racing season HPD has decided to forego having a works team and instead focus on being a chassis and engine provider. 2012 will also see the HPD return to the premier class of racing, LMP1, in the Le Mans and FIA World Endurance Championship series.
