Formula Junior

Formula Junior was an international single-seater motor racing category that existed between 1958 and 1963. Devised by Italian motorsport promoter Count Giovanni "Johnny" Lurani, the formula was created as an accessible training ground for young drivers advancing from karting or amateur competition to professional-level open-wheel racing. Regulations required the use of production-based engines and components sourced from small road cars, which helped contain costs and encouraged participation by privateers and smaller manufacturers.

The category quickly gained traction in Europe and the United States, evolving from a national class in Italy to an internationally recognized formula. While early success came from front-engined Italian cars such as those produced by Stanguellini, British constructors including Lotus, Cooper, and Brabham soon rose to prominence through the adoption of lighter, rear-engined designs.
