This contemporary “World Formula” used to be at the origin known variously as Formula A, Formula I, or Formula 1 with the corresponding “Voiturette” system being titled Formula B, Formula II, or Formula 2. When the 500c system used to be internationally recognised as Formula 3 in 1950 it used to be in no method titled as “Formula C” so the three World Formulae were then “formally” titled Formula 1, Formula 2 and Formula 3.
At the beginning, the system used to be largely in step with pre-World War II laws outlined by engine ability. The law expected to raise a recent steadiness between supercharged and assuredly aspirated vehicles. Non-supercharged 4.5-litre pre-battle Gigantic Prix vehicles were allowed to flee against the pre-battle 1.5-litre supercharged ‘voiturettes’, while pre-battle supercharged 3-litre Gigantic Prix vehicles were banned.
