Formula Student is a student engineering competition held annually all over the world. Student teams from around the world design, build, test, and race a small-scale formula style racing car. The cars are judged on a number of criteria as listed below. It is run by the Institution of Mechanical Engineers and uses the same rules as the original Formula SAE with supplementary regulations. Ambassadors of Formula Student include David Brabham, Paddy Lowe, Willem Toet, Leena Gade, Dallas Campbell, Mike Gascoyne, and James Allison. Formula Student partnered with Racing Pride in 2019 to support greater inclusivity across the British motorsport industry for LGBT+ fans, employees and drivers. Class definitions There are two entry classes in Formula Student, designed to allow progressive learning. Formula Student Class (formerly Class 1) This is the main event, where teams compete with the cars they have designed and built. Teams are judged across 6 categories and must pass a rigorous inspection by judges before being allowed to compete for the dynamic events. There are usually 100-120 teams in this class. Concept Class (formerly Class 2) This is a concept class for teams who only have a project and plan for a Class 1 car. It can include any parts or work that has been completed in the project so far but this is not necessary. Teams are judged on business presentation, cost and design. Schools can enter both FS Class and Concept Class cars, allowing Concept Class to be used for inexperienced students to practise their development in advance of a full Formula Student Class entry. Class 1A (pre-2012) This was an alternative fueled class with the emphasis placed upon the environmental impact of racing. A car from the previous year's Class 1 entry could be re-entered and re-engineered allowing the students to concentrate on the low carbon aspect of the competition without having to redesign a new chassis and ancillaries. Cars in Class 1A were judged in the same events alongside Class 1 however the cost category was replaced by one for sustainability and the endurance event had a greater emphasis placed upon measured emissions. Class 1A cars were scored and ranked independently of Class 1. Since 2012, both Petroleum and Alternative fueled cars have competed for places in the same rankings. Class 2A (pre-2012) This was a concept class for teams who only had a project and plan for a Class 1A car.
