GR - GENERAL REGULATIONS GR.1 GR.1.1

FORMULA SAE COMPETITION OBJECTIVE Collegiate Design Series SAE International's Collegiate Design Series (CDS) programs prepare undergraduate and graduate engineering students in a variety of disciplines for future employment in mobilityrelated industries by challenging them with a real world, engineering application. 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. GR.1.2

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.

GR.1.3

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.

GR.1.4

Vehicle Design Objectives

GR.1.4.1 Teams are to assume that they work for an engineering firm that is designing, fabricating, testing and demonstrating a prototype vehicle. GR.1.4.2 The vehicle should have high performance and be sufficiently durable to successfully complete all the events at the Formula SAE competitions. GR.1.4.3 Additional design factors include: aesthetics, cost, ergonomics, maintainability, and manufacturability. GR.1.4.4 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. GR.1.5

Good Engineering Practices Vehicles entered into Formula SAE competitions should be designed and fabricated in accordance with good engineering practices.
