Culminating four years of competition, General Motors Corp. and the United States Department of Energy will host a finish line ceremony and press conference featuring vehicles from the collegiate engineering competition, "Challenge X: Crossover to Sustainable Mobility."

The event marks the end of the Challenge X competition and concludes a 350-mile road rally from New York City to Washington, D.C. Following the press conference, select vehicles will be available for brief ride and drive opportunities.

Challenge X is a unique multi-year engineering competition that provides 17 university teams from across North America with real-world engineering experiences and the opportunity to follow the GM global vehicle development process to create advanced propulsion technology solutions that will that will increase energy efficiency, reduce environmental impact and fundamentally change the way we power our automobiles.

Seventeen Chevrolet Equinox SUVs have been re-engineered by student teams using a range of cutting-edge clean vehicle technologies such as hybrid, plug-in or fuel cell propulsion systems. The vehicles are powered by alternative fuels such as biodiesel, ethanol and hydrogen.  

Michigan teams in the competition include Michigan Technological University in Houghton and the University of Michigan Ann Arbor.      

The event will be held Wednesday, May 21 from 10:15 to 11:30 a.m.  at the DoE's L’Enfant Plaza Promenade in Washington, D.C.
