Seattle, Washington [RenewableEnergyAccess.com] Seattle’s municipal area, King County, was awarded a contract for the purchase of up to 500 articulated buses, most of which will be powered by General Motors’ 2-mode hybrid system. The five-year contract, which could be worth $400 million, is between King County and bus-manufacturer New Flyer Industries. General Motors supplies New Flyer with the hybrid system for the buses. King County has been operating a fleet of 214 GM hybrid-powered buses since 2004 and, with the addition of this contract, King County could have a total of 714 buses. The National Renewable Energy Laboratory’s (NREL) one-year comparative study of King County’s hybrid buses endorses GM’s 2-mode hybrid propulsion system.
