Mayor Newsom Signs Legislation Improving Muni's Hybrid Biodiesel Buses
05/19/09 - Today Mayor Gavin Newsom signed legislation that will allow Muni, which is operated by the San Francisco Municipal Transportation Agency (SFMTA), to replace existing lead-acid batteries with advanced lithium-ion batteries. The new batteries will improve the reliability of Muni's hybrid biodiesel buses and save the transit agency millions of dollars over the life of the vehicles.
Muni's 86 hybrid biodiesel buses already get 25 percent more miles per gallon than conventional buses; the lithium-ion batteries are expected to increase the fuel economy of the hybrids by an additional 15 percent. The funds saved from this action will be invested in the maintenance and repair of the Muni fleet.
San Francisco remains committed to having the greenest transit fleet in the United States. More than half of the vehicles in the Muni fleet—including light rail vehicles, electric trolley buses, cable cars and historic streetcars—are zero emissions.
