BAE Systems is providing 42 electric drive systems to the San Francisco Municipal Transpiration Agency’s (SFMTA) new hybrid-electric bus fleet.

Getting BAE Gen3 Drive Systems

The company will deliver its Gen3 electric drive systems to New Flyer for integration into the vehicles, providing San Francisco with cost-effective technology that can reduce fuel use and emissions.

BAE Systems’ electric drive technology has been operating on SFMTA buses since 2007. The Gen3 system builds on proven components with next-generation developments, such as incorporating advanced materials like silicon carbide and designs to maximize electrical efficiency. 

With nearly three decades of continuous innovation, the system will help SFMTA maintain a reliable and efficient transit operation.

“BAE Systems’ Gen3 system will help the SFMTA achieve its goals by providing dependable, zero-emission capable technology,” said Bob Lamanna, vice president and general manager of Power & Propulsion Solutions at BAE Systems. “Hybrid buses equipped with our technology will deliver immediate benefits, such as reducing emissions and improving air quality, while advancing San Francisco toward a zero-emission transit system.”

Looking at What the New Drive Systems Provide

The Gen3 system includes a traction motor, onboard energy storage, and smart-power electronics to create a clean, integrated electric propulsion and accessory power system for the buses.

The simplified solution, which uses upgraded modular power control systems and electric motors that use fewer components, increases reliability and makes service easier.

Hybrid buses with BAE electric drive systems offer engine start-stop and geofencing technology to automatically switch to full electric mode in designated green areas.

BAE has nearly 30 years of experience developing and integrating electric poweto switch to full electric mode in designated green areas automaticallyr and propulsion systems for buses and heavy-duty vehicles. The company has more than 19,000 propulsion systems on transit buses worldwide.
