Nicknamed Borealis III, the car ran fourth out of 10 teams. Winning was a team from Japan followed by two Taiwanese teams.
Team leader Patrick O'Connor says the vehicle was just as fast as the competition but tires and an occasional gremlin hampered a winning effort. The 3-day race had timed and untimed segments, including drives through traffic.
The Minnesota car was capable of 85mph sprints while the winner topped 100mph.
The university team will start work on a new car soon.
