The Acura ARX-02a is a Le Mans prototype of the LMP1 class developed by Honda Performance Development and Wirth Research , which has been used in sports car races since 2009 and is the successor to the Acura ARX-01 .


Highcroft Racing and De Ferran Motorsports fielded two ARX-02a in the American Le Mans Series in 2009 on behalf of Acura . The debut took place at the 12-hour race at Sebring , in which both cars retired due to technical defects. The following three championship races were won by the ARX-02a.


The Acura ARX-02a was presented to the public for the first time on January 26th, 2009 during the winter tests of the ALMS in Sebring . The first secret tests were carried out in Sebring the previous December.

A special feature of the vehicle is that the same tire size (37-71 / 18) is used on the front and rear axles. Due to the larger Michelin tires, some of the aerodynamically generated grip can be dispensed with. Another novelty was the rear spoiler hung from the front. Complete development was done by Honda Performance Development in California and Wirth Research in the UK. Only Xtrac provides the largest externally manufactured component of the vehicle with the six-speed transmission.

The engine, the Acura LM-AR7, has a displacement of four liters, is built in a V8 design and is powered by an E10 . The maximum power is approximately 456 kW (620 PS) mobilized.

The ARX-02a is equipped with an open cockpit and double roll bar.
