1921 Grand Prix season

The 1921 Grand Prix season saw motor racing in Europe blossom again. The French Grand Prix was held for the first time since 1914, at La Sarthe, Le Mans. and the inaugural Italian Grand Prix was held in Montichiari, near Brescia. The 3-litre formula of the AIACR, already in use at Indianapolis, was adopted by those Grand Prix meaning manufacturers could design on a common formula.
