Formula SAE

What is FSAE?

Formula SAE is a collegiate design competition organized by SAE International. This design series is geared toward university-level automotive engineering projects, including an electric division, FSAE Electric.

FSAE Electric features a weekend-long design competition for university teams to compete their student-crafted electric race cars with each other. At the FSAE Electric competition, race cars are judged on their rules compliance, student design, business sales presentation, and on-track performance.

How is Formula Slug involved?

Formula Slug entered FSAE Electric in the Fall of 2015, producing our first electric vehicle, FS-0. Due to late error review, we were unable to compete with FS-0 and dedicated the car to research and learning projects thereafter. 

We are currently designing for the 2019 FSAE Electric with FS-1 on a two-year design cycle.
