Why it matters

Fiat's car for the 2-litre Grand Prix formula of 1922, with a six-cylinder twin-cam engine (Type 404). It won both Grand Prix held that season, and its supercharged 1923 development was the first to win a Grand Prix with forced induction.

02Production & history

Production

Every figure says what it counts.

No production figures recorded yet.

History

The formula for 1922 set a 2-litre limit and a minimum weight of 650 kg, and Fiat used a six with two valves per cylinder; most components came from an earlier 3-litre car. Felice Nazzaro won the French Grand Prix at Strasbourg and Pietro Bordino the Italian one. For 1923 the engine was changed and supercharged, giving about 130 hp in the Type 405, and Fiat withdrew from Grand Prix racing in 1924. The first supercharger was a Wittig type, later replaced by a Roots type.
