Allison Transmission Japan, the Japanese subsidiary of Allison Transmission, has exhibited the company’s eGen Power, integrated zero-emission electric axle for the first time in Japan at the Automotive Engineering Expo Online.

Allison has stated it has launched the Allison eGen brand with an investment of approximately $US250 million over the past three years to develop electric hybrid and fully electric propulsion technology as a responsible corporate citizen to realize a zero-emission society around the globe.

The eGen Power Series, is being exhibited for the first time in the Japanese market, and is a fully integrated system with dual electric motors, a multi-speed gearbox, a gear actuator and an oil cooler that minimises the need for changes to the current chassis and suspension design.

The extremely compact design leaves critical space between the wheels for batteries and/or auxiliary equipment. The multi-speed gearbox is optimised for both low speed gradeability and high-top speed without sacrificing efficiency. Compatible with axle weights of from 10 to 13 tonnes, the dual motor eGen Power is among the most powerful propulsion solutions in its class according to Allison, with continuous power of 557 horsepower (416 kilowatts) and peak output power of 722 horsepower (539 kilowatts) with a power supply of 650V.

Allison announced that Emergency One, a leader in the United Kingdom in fire and rescue vehicles, signed a memorandum of understanding with Allison in April 2021 to sell Emergency One vehicles equipped with Allison’s eGen Power  because of the  high performance, reliability, excellent acceleration, and maneuverability it delivers.

Allison say it is continuing to work with commercial vehicle manufacturers around the world to build a decarbonized society by developing new technologies to increase efficiency and make effective use of the earth’s limited resources.
