context_page_description: Since its inception in 1947, Formula One has used a variety of engine regulations. "Formulae" limiting engine capacity had been used in Grand Prix racing on a regular basis since after World War I. The engine formulae are divided according to era.
context_section_description: This era used pre-war voiturette engine regulations, with 4.5 L atmospheric and 1.5 L supercharged engines. The Indianapolis 500 (which was a round of the World Drivers' Championship from 1950 onwards) used pre-war Grand Prix regulations, with 4.5 L atmospheric and 3.0 L supercharged engines. The power range was up to 425 hp (317 kW), though the BRM Type 15 of 1953 reportedly achieved 600 hp (447 kW) with a 1.5 L supercharged engine.
  In 1952 and 1953, the World Drivers' Championship was run to Formula 2 regulations, but the existing Formula One regulations remained in force and a number of Formula One races were still held in those years.
