High Quality Content by WIKIPEDIA articles! The Acura ARX-01 (2010 onwards known as "HPD ARX-01") is a Le Mans Prototype built for sports car racing, specifically in the American Le Mans Series. It is the first purpose-built race car by the Acura division of Honda Motor Company, part of their multi-year program to eventually compete in the 24 Hours of Le Mans endurance race. Two of the three Acura teams, Highcroft Racing and Andretti Green Racing, initially used the ARX-01a in 2007, while Lowe`s Fernandez Racing used a Lola chassis with the Acura engine. In 2008, an upgraded ARX-01b was introduced for all teams, with the addition of a fourth team run by Gil de Ferran. In 2010 the Acura name was dropped from the program and the ARX-02 was badged by Honda Performance Development which had developed the program.
