Longtime Le Mans participant WR is set to return to Circuit de la Sarthe in 2016 as a potential Garage 56 entry with a biogas-powered prototype.

The French squad, which last took part in the twice-around-the-clock endurance classic in 2010, has launched a new project that will showcase alternative technology.

The car will utilize a 1.6-liter 3-cylinder engine running on biogas, which is primarily made up of methane and carbon dioxide. It will be outfitted with a cryogenic fuel tank and will feature liquid injection.

Led by Gerard Welter, the project also sees involvement from a number of former Renault and Peugeot motorsport staff, including Jean-Pierre Boudy, Guy Audoux and Vincent Soulignac.

Construction of the car, built to FIA LMP regulations, is set to begin next year, with plans to present the all-new prototype during next year’s 24 Hours of Le Mans, with the goal of securing the Garage 56 entry in 2016.
