1993 "Maize & Blue" University of Michigan Solar Car - Sunrayce 93

Sunrayce 93

There were three qualifiers for Sunrayce 93; the first two several months prior to the race start and the third "last chance" qualifier held in the weeks before the actual race start. The qualifiers were used to determine that the vehicles met all of the race regulations and also to determine the starting positions. Maize & Blue completed the qualifier held at the Indianapolis Motor Speedway and qualified to start in the 10th position.

The race was held over seven days from June 20–26, 1993. The race began at the recently-opened Ballpark in Arlington (now known as Ameriquest Field) in Arlington, Texas and finished at the Minnesota Zoo in Minneapolis, Minnesota.

By the end of the first race day, Maize & Blue had moved from 10th into 1st place, just a few minutes ahead of the second place car from Cal Poly Pomona. Pre-race favorite Cal State LA suffered debilitating electrical failures on day 1 putting them out of contention for the remainder of the race. Over the next three days, the team jockeyed for position at one point falling behind first place by as much as 20 minutes, primarily due to two penalties levied by race officials for violation of traffic rules.

On day 5 of the race, the weather forecast called for rain and overcast conditions for most of the day. Maize & Blue was the only car to finish that leg of the race under its own power (the Iowa State University car finished ahead of Michigan, but incurred a 10-hour penalty for replacing their battery pack at the start of the day). On day 5, the Michigan team accumulated a 90-minute lead over the next fastest car.

Days 6 and 7 were uneventful with Maize & Blue maintaining its lead and finishing in first place overall followed by Cal Poly Pomona in second and Cal State LA in third. Maize & Blue finished with an average speed of 27.29 mph over the 1100-mile course edging out the second place car by 90 minutes. The victory gave Michigan its second consecutive national championship in solar car racing.
