17 North America Universities Selected in Groundbreaking Fuel Economy and Vehicle Emissions Competition

             'Challenge X: Crossover to Sustainable Mobility'

  What:         General Motors, the US Department of Energy and other
                government industry leaders have developed a new advanced
                vehicle technology competition, Challenge X: Crossover to
                Sustainable Mobility, which challenges engineering students
                across North America to explore vehicle solutions that
                minimize energy consumption and reduce emissions, while
                maintaining the vehicle's utility and consumer appeal.

                From more than 3,000 accredited engineering schools in North
                American, 17 universities have risen to the challenge.  The
                teams will be announced during a May 11, 2004 press
                conference in Washington, DC.  Participating students and
                faculty advisors will be available for interviews and
                pictures.

  Who:          David Garman, Acting Undersecretary & Assistant Secretary
                Energy Efficiency; Tom Stephens, Group Vice President of
                Powertrain-General Motors; will announce the seventeen North
                American university teams who have been selected to
                participate.

  Where:        Loews L'Enfant Plaza Hotel, Washington DC,

  About Challenge X:  Crossover to Sustainable Mobility Competition:

General Motors, the US Department of Energy (DOE) and other partners launched a competition series that challenges engineering students from universities throughout North America to re-engineer a crossover vehicle to achieve better fuel economy and lower emissions. The program provides the opportunity for engineering schools to participate in real-world research and math intensive development with leading edge automotive propulsion, fuels, materials and emissions-control technologies. The competition, launched for the 2004/2005 academic year, is a three-year program.
