Team PrISUm is the multidisciplinary student-run solar car racing team from Iowa State University that designs and builds solar powered vehicles to compete in the American Solar Challenge (ASC). The club was founded in 1989 by a group of engineering honor students from Tau Beta Pi and was simply known as the ISU Solar Car Project. In 1990, the team adopted the name of its first car, PrISUm.

Team PrISUm is currently working on their 13th solar powered electric vehicle for the 2016 competition.


  • Since 1989, Team PrISUm has built and raced 12 different cars and is the only team to have qualified and raced a new vehicle for all the Sunrayce and American Solar Challenge races.
  • Team PrISUm made the first solar car from the state of Iowa with its entrance in the 1990 GM Sunrayce USA.

Team Composition[edit]

Team PrISUm consists of about 60 team members from the Iowa State University campus and welcomes students from all majors interested in working on any aspect of the diverse project. The team has three distinct divisions that are each necessary for successfully designing, racing, and teaching the public about solar cars.

  • The Electrical Division is responsible for designing and building the battery system, solar array, power electronics, controls and software for the car.
  • The Mechanical Division is responsible for the design, testing, and fabrication of the outside shell of the vehicle and all the mechanical components for the car.
  • The Business Division is responsible fundraising, project budgeting, outreach, recruiting, and media.
