Formula One was first defined in 1946 by the Commission Sportive Internationale (CSI) of the FIA, forerunner of FISA, as the premier single seater racing category in worldwide motorsport. It was initially known as Formula A, but the name Formula One was widely used early on and became official in 1950.

In the beginning, the formula was largely based on pre-war regulations defined by engine capacity. The regulation expected to bring a new balance between supercharged and normally aspirated cars. Non supercharged 4.5 litres pre-war Grand Prix cars were allowed to race against the pre-war 1.5 litres supercharged 'voiturettes' while pre-war supercharged Grand Prix cars were banned.

The first race under the new regulations was the 1946 Turin Grand Prix held on 1 September, the race being won by Achille Varzi in an Alfa Romeo 158 Alfetta, although in reality the cars were no different to those that had raced earlier in the season.  1946 Turin Grand Prix held at Valentino Park in Turin, Italy.
