Allison collaborates with Cummins for electric hybrid system

Allison Transmission and Cummins are collaborating on an electric hybrid propulsion system.

The project will integrate and certify a Cummins B-Series engine with the Allison eGen Flex electric hybrid propulsion system ready for 2027.

eGen Flex is designed to be capable of operating up to 50% of a bus’s typical route in engine-off mode, intended to provide a solution that is particularly beneficial in reducing emissions in urban areas. The system’s 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-emission zones.

“This initiative continues Allison’s position at the forefront of sustainable transportation” – Rohan Barua, Vice President of North America Sales, Global Channel and Aftermarket at Allison Transmission

Rohan Barua, Vice President of North America Sales, Global Channel and Aftermarket at Allison Transmission, said: “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.”
