1930 Grand Prix season
The 1930 Grand Prix season primarily featured cars from the French and Italian car manufacturers Bugatti and Maserati. All six finishers at the Monaco Grand Prix drove Bugattis. Achille Varzi won two races driving a Maserati.
The World Manufacturers' Championship was planned on seven races, with European Grand Prix and other two mandatory; four races were cancelled, another was raced with sport-cars regulation. Moreover European Grand Prix was shorter than the minimum of 600 kilometres. For these reasons, the championship was cancelled.
In the late summer AIACR started to work on the new European championship which would begin in 1931.
