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. 1993 World Solar Challenge Between Sunrayce 93 and the 1993 World Solar Challenge, the team made many changes to Maize & Blue, the two most important being replacing the lead acid battery pack with an equivalent capacity silver-zinc pack which resulted in a significant weight savings and the other being replacing about 40% of the solar cells with high-powered "Green Cells" produced specially for the team by Dr. Martin Green at the University of New South Wales. Unfortunately, as a result of an assembly flaw during the encapsulation process the new cells were unable to produce peak power output resulting in lower total array power. There were other minor changes to the vehicle designed to reduce weight or aerodynamic drag (the most notable with the removal of all decals except those required by race officials). Maize & Blue finished in 11th place in the 1993 World Solar Challenge. Honda won the 1993 World Solar Challenge followed by the team from Biel University. Maize & Blue finished the race ahead of the 1990 University of Michigan Sunrunner's record of 5 days, but that was not enough for a top finish.
