Allison Transmission and Cummins partnered for a new electric drivetrain for the transit market.
The solution pairs a Cummins B-series engine with the Allison eGen Flex electric hybrid propulsion system. It will meet the EPA's Greenhouse Gas Emissions Standards, Phase 3. It is expected to be available in 2027.

"This initiative continues Allison's position at the forefront of sustainable transportation with our comprehensive portfolio of propulsion solutions, which includes fully electric axles and fuel-efficient conventional transmissions that pair seamlessly with alternative fuels and electric propulsion, in addition to the eGen Flex electric hybrid solution for the transit industry," says Rohan Barua, vice president of North American sales, global channel and aftermarket at Allison Transmission.

The drivetrain is capable of operating up to 50% of a bus's typical route in engine-off mode, the companies say. The electric-only mode is activated through geofencing technology and eliminates engine emissions and noise while loading and unloading passengers and when operating in predefined dense pedestrian areas and zero-emissions zones.
