Ricardo designed the 1921 T.T. Vauxhall engine which was described by Cecil Clutton in Motor Sport as a tour de force[10] in the 1922 RAC T. T. O Payne in the Ricardo Vauxhall came 3rd, Jean Chassagne on a 1921 Grand Prix Sunbeam winning outright.[11] The engine was later developed by Mays and Villiers, who fitted a supercharger, and was still a winner fifteen years later.[12]
