6 Through the Engineering Design Process, experiences may include but are not limited to: Project management, budgeting, communication, and resource management skills Team collaboration Applying industry Rules and regulations Design, build, and test the performance of a real vehicle Interact and compete with other students from around the globe Develop and prepare technical documentation Students also gain valuable exposure to and engagement with industry professionals to enhance 21st century learning skills, to build their own network and help prepare them for the workforce after graduation. Formula SAE Concept The Formula SAE competitions challenge teams of university undergraduate and graduate students to conceive, design, fabricate, develop and compete with small, Formula style vehicles.
7 Engineering Competition Formula SAE is an engineering education competition that requires performance demonstration of vehicles in a series of events, both off track and on track against the clock. Each competition gives teams the chance to demonstrate their creativity and engineering skills in comparison to teams from other universities around the world. Vehicle Design Objectives Teams are to assume that they work for an engineering firm that is designing, fabricating, testing and demonstrating a prototype vehicle. The vehicle should have high performance and be sufficiently durable to successfully complete all the events at the Formula SAE competitions. Additional design factors include: aesthetics, cost, ergonomics, maintainability, and manufacturability.
8 Each design will be judged and evaluated against other competing designs in a series of Static and Dynamic events to determine the vehicle that best meets the design goals and may be profitably built and marketed. Good Engineering Practices Vehicles entered into Formula SAE competitions should be designed and fabricated in accordance with good engineering practices. Formula SAE Rules 2021 2020 SAE International Page 6 of 136 Version 30 July 2020 Restriction on Vehicle Use SAE International, competition organizer(s) and officials are not responsible for use of vehicles designed in compliance with these Formula SAE Rules outside of the official Formula SAE competitions. Formula SAE Rules AND ORGANIZER AUTHORITY Rules Authority The Formula SAE Rules are the responsibility of the Formula SAE Rules Committee and are issued under the authority of the SAE International Collegiate Design Series.
9 Rules Validity The Formula SAE Rules posted on the website and dated for the calendar year of the competition are the Rules in effect for the competition.
