Since 2004, 430 GM hybrid-powered buses have been delivered to communities in the US and Canada and are currently being demonstrated to government officials in Australia.


By the end of the year, another 237 GM hybrid-powered buses are expected to be delivered to several cities.


The hybrid technology is manufactured by GM Allison Transmission, maker of transmissions and hybrid propulsion systems for commercial trucks, buses, off-highway equipment and military vehicles, headquartered in Indianapolis.


Gillig Corp. of Hayward, Calif., manufactured the bus.


The hybrid technology in these buses has served as the starting point for GM’s co-development with DaimlerChrysler and BMW Group of a two-mode hybrid system that GM will launch next year in the Chevrolet Tahoe and GMC Yukon fullsize SUVs, followed by the Cadillac Escalade in 2008.
