 The race was significant in advancing aeroplane design, particularly in the fields of aerodynamics and engine design, and would show its results in the best fighters of World War II.The streamlined shape and the low drag, liquid-cooled engine pioneered by Schneider Trophy designs are obvious in the British Supermarine Spitfire, the American North American P-51 Mustang, and the Italian Macchi C.202 "Folgore".If an aero club won three races in five years, they would retain the trophy and the winning pilot would receive 75,000 francs for each of the first three wins.
