The grueling endurance test pitted UM-Rolla’s “Solar
Miner IV” against race teams from some of the
most famous engineering schools in the nation. By
driving approximately 2,300 miles from Chicago to
Claremont (a suburb of Los Angeles), in just 51
hours, 47 minutes and 39 seconds, they set a race
record by more than four hours.
