eGen Power®

eGen Power® e-Axles are the next evolution in electric commercial vehicles from a leader in propulsion solutions. Designed to fit between the wheels of medium- and heavy-duty trucks and buses, eGen Power is tomorrow’s technology in today’s changing landscape.

The eGen Power single-motor 85S (8.5t), 100S/130S (10t/13t) and dual-motor 100D/130D (10t/13t) are built on Allison’s proven expertise in vehicle integration, battery management and vocational knowledge. Allison’s e-Axles represent efficient, compact and high-performance combinations, all with proven Allison reliability and durability.

A Closer Look at What Drives Us

As the most compact form in its class, our fully integrated system allows more room for battery packs and other critical EV components, giving your fleet more range and better maneuverability.

Our innovative regenerative braking system and gear layout allows for maximum efficiency and 100% regeneration torque capability, reducing brake wear and extending the vehicle’s range.

With standard panhard mounting and suspension locations, eGen Power is a bolt-in solution for existing truck and chassis designs while still allowing flexibility for customization. This frees up space between frame rails where a drivetrain would typically be located and allows batteries to be installed in-board which improves impact protection and vehicle dynamics.

Our integrated electric motors, oil cooler and electric on-demand pump are easier and less expensive to install. The e-Axle housing offers reduced pipe runs and less flex between sprung and unsprung components, giving you simpler packaging and better durability.

Experience equal or better performance with a smaller, lighter and less expensive motor. eGen Power’s multi-speed gear box provides better gradeability at lower speeds while maintaining top speed and efficiency.
