Both consist of regional competitions that simulate real-world engineering design projects and their related challenges. For SAE Aero, while integrating several engineering disciplines: aeronautical, mechanical, electrical, and computer engineering, teams are required to create an aircraft, trading between two potentially conflicting requirements, carrying the highest payload fraction possible, while simultaneously pursuing the lowest empty weight possible. For the SAE Baja, Engineering students are tasked to design and build an off-road vehicle that will survive the severe punishment of rough terrain and sometimes even water.
