Since 2003, more than 640 GM hybrid-powered buses have been delivered to 51 cities in Canada and the US. The hybrids deliver better fuel economy than traditional buses and produce up to 60% fewer oxides of nitrogen emissions and 90% fewer particulate, hydrocarbon and carbon monoxide emissions.

The two-mode hybrid technology in these buses has served as the starting point for GM’s co-developed two-mode hybrid system for light-duty vehicles that GM will launch next year in the Chevrolet Tahoe and GMC Yukon full-size SUVs and the Chevrolet Silverado and GMC Sierra pick ups.
