Team PrISUm raced and raced and raced around the Indianapolis Motor Speedway on Friday.

The racing went so well, Iowa State University’s solar race car team nearly doubled its lap count from the first day of this year’s Formula Sun Grand Prix for student-designed and student-built solar race cars.

“We were driving around the track the whole day and going fast the whole time,” said Evan Stumpges, a team leader and a senior in mechanical engineering from Pauma Valley, Calif.

Stumpges, who drove the team’s $250,000 racer during the morning shift, said there were only a couple of small problems with the car all day: a tire blew out and a brake light wasn’t working right. But the repairs didn’t take much time, and the team was able to pile up 164 laps for the day.
On Thursday, lengthy repairs to a cracked frame tube kept the team off the track for hours. That meant only 83 laps for the day.
