BAE Systems to power new hybrid-electric bus fleet in San Francisco

BAE Systems will supply 42 electric drive systems for the San Francisco Municipal Transportation Agency's new fleet of hybrid-electric buses. The delivery includes the company's Gen3 electric drive systems, designed for integration into buses manufactured by New Flyer, with the goal of reducing fuel consumption and emissions.

BAE Systems' technology has been in operation on SFMTA buses since 2007. The Gen3 system features advanced materials and a lightweight design that improves electrical efficiency. The company emphasizes its commitment to service and aims to support the SFMTA's transition to a zero-emission transit system.

“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.”

The Gen3 system includes a traction motor, onboard energy storage, and smart power electronics, all aimed at creating a clean, integrated electric propulsion system. The modular power control system has been updated to use fewer components, which increases reliability and simplifies maintenance while offering a quieter ride.

The hybrid buses utilizing BAE Systems' electric drive systems incorporate features like engine start-stop and geofencing technology, allowing automatic switches to full electric mode in designated areas, which grants zero-emission benefits without needing external charging.

With nearly 30 years of experience, BAE Systems has over 19,000 propulsion systems in service on transit buses globally, including hybrid-electric, battery-electric, and hydrogen fuel cell applications. The company's electric propulsion technology is developed and serviced at its facilities in Endicott, New York and Rochester, UK.
