(Reuters) - The World Endurance Championship (WEC) and its Le Mans 24 Hours showcase will switch in 2022 to a 100% renewable fuel derived partly from French wine industry residues, organisers said on Friday.

The Automobile Club de l'Ouest (ACO), which runs Le Mans, said TotalEnergies would provide a fuel with a bioethanol base, derived from wine lees and grape pomace and blended with an ethanol by-product from feedstock.
