Editing Formula Two (section)

=== Pre-war ===
Prior to the Second World War, there usually existed a division of racing for cars smaller and less powerful than Grand Prix racers. This category was usually called [[voiturette]] ("small car") racing and provided a means for amateur or less experienced drivers and smaller marques to prove themselves. By the outbreak of war, the rules for voiturette racing permitted 1.5 L supercharged engines; Grand Prix cars were permitted 3.0 L supercharged or 4.5 L [[naturally aspirated engine|naturally aspirated]].
