At General Motors, we are committed to both the transportation that improves people's lives and the environment that sustains us. This is a vision we call sustainable mobility, one in which vehicles pollute less, consume less, and improve the quality of our lives even more. Although GM has pioneered many fundamental automotive technologies that have drastically reduced exhaust emissions during the last 30 years (down over 98% for hydrocarbons and carbon monoxide and 90% for oxides of nitrogen), we believe the ultimate solution lies in hydrogen powered fuel cell vehicles. That's why GM is spending the largest portion of its research and development budget to commercialize fuel cell technology. Among several other advancements in this area, GM's fuel cell vehicle development has resulted in the Hy-Wire, the world's first drivable vehicle that combines a hydrogen fuel cell with by-wire technology. Our goal is to establish the commercial viability of compelling, affordable fuel cell vehicles by 2010, and to be the first automaker to profitably sell one million fuel cell vehicles. Until fuel cells are produced in large numbers, however, hybrid propulsion systems will be a key element of GM's advanced technology plans. Hybrid technologies will provide an important bridge to a hydrogen economy and fuel cell systems that power our vehicles, and even our homes and business. Although significant technical and business challenges must be addressed on the way to a hydrogen economy, GM already has about 600 people working on fuel cell technology at its three U.S. facilities in Honeoye Falls, N.Y.; Warren, Mich.; and Torrance, Calif. GM also has a research facility in Mainz-Kastel, Germany; and offices in Tokyo.
