At the 2006 North American International Auto Show in Detroit, Acura officially announced their plans to develop a Le Mans Prototype program for the American Le Mans Series, competing in the LMP2 class for the initial year of competition in 2007. Acura announced they'd be using customer chassis from Lola Cars International of the United Kingdom and Courage Compétition of France, while the engine would be built entirely by Honda Performance Development of the United States. Acura planned to use the customer chassis for the first year, then to build their own chassis for 2008, followed by another new chassis for a move to the top LMP1 class in 2009. At the Detroit auto show, Acura showed their first customer chassis, a brand new Courage LC75.
