BAE Systems and Cummins Inc. announced plans to collaborate on the integration and certification of a B hybrid-compatible diesel engine and hybrid-electric drivetrain for the transit market, targeted for launch in 2027.

The hybrid-electric solution will continue to provide transit agencies with a proven and cost-effective technology that reduces fuel use and emissions, according to BAE and Cummins.

How the BAE/Cummins Partnership Will Work

In this effort, BAE Systems will supply its electric drive hardware to interface with the engine and form a full hybrid electric drivetrain, as well as provide engineering support and system integration expertise.

“Hybrid-electric systems will remain an important technology for the bus market for years to come,” said Rob Dykema, director, North American transit accounts for power & propulsion solutions, at BAE Systems. “BAE Systems and Cummins have enjoyed many years of successful collaboration delivering this proven capability to the market, and this is another step forward as we sustain a range of clean, efficient solutions in transit.”

BAE Systems and Cummins have worked together to develop hybrid-electric solutions for buses since 1994. The newly expanded collaboration underscores a shared commitment to offering more emission-reducing options in transit.

Benefits of Hybrid-Electrics

Hybrid-electric buses facilitate workforce development for training on high-voltage systems and do not require investment in extensive charging infrastructure.

In addition, hybrid buses with BAE Systems’ electric drive systems allow for increased zero-emission capable solutions, including proven engine start and stop and geofencing technology, allowing a hybrid bus to automatically switch to full electric bus mode when entering designated green zones.
