Engineering students from Virginia Tech University, utilizing E85/hybrid technology, beat out teams from 16 other universities in the U.S. and Canada to win the second annual Challenge X: Crossover to Sustainable Mobility competition, sponsored by the Department of Energy and General Motors last week in Mesa, Arizona. The Virginia Tech team redesigned a 2005 Chevy Equinox to utilize a split parallel hybrid that runs on E85 to edge out second-place Mississippi State University.
