GM delivers hybrid power for bus added to SporTran transit fleet

SHREVEPORT, La. - SporTran demonstrated its on-going commitment to clean air today by announcing the addition of a hybrid bus to its mass transit fleet. SporTran and the city of Shreveport join the growing ranks of communities investing in transit buses powered by General Motors' hybrid technology, which offers greater fuel economy and cleaner emissions than conventional diesel buses.

In a media event today at Stoner Boat Launch, the city of Shreveport unveiled the bus - the very first hybrid-powered bus to operate in the state of Louisiana. On hand for the festivities were representatives from the city, SporTran, The Department of Environmental Quality and Environmental Protection Agency, the city's Clean Air Committee and General Motors.

Transit buses with GM's hybrid propulsion system provide a significant fuel economy improvement over conventional diesel buses, with a range of 25 to 55 percent fuel economy improvement depending on the route and driving conditions. To date, GM has delivered 353 hybrid buses to urban mass transit systems in 23 cities.

"The GM diesel-electric drive system for buses uses the most efficient parallel hybrid architecture available in the world today and is manufactured by GM Allison in Indianapolis," said David Gibbons, plant manager, GM Shreveport Operations. "We think it is an excellent investment for urban transit bus fleets and applaud SporTran for its efforts."

In addition, the hybrid buses provide dramatically lower emissions, including 90 percent fewer particulate, hydrocarbon and carbon monoxide emissions. Other benefits include reduced maintenance costs resulting from extended brake, engine oil and transmission oil life; superior torque and better acceleration than conventional diesel buses and operation sound levels equal to passenger cars even in tunnels.

The clean 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 buses.

The technology in these buses has served as the starting point for GM's co-development with DaimlerChrysler of a hybrid system that GM will launch in the Chevrolet Tahoe and GMC Yukon in late 2007.
