Allison Transmission launches new zero emission electric axles

Allison Transmission has launched eGen Power, its new zero emission electric axles for medium and heavy-duty commercial trucks.

The eGen Power product family, previously referred to as AXE for trucks, will be the second product offering under the recently announced Allison eGen portfolio of fully electric and electric hybrid propulsion solutions. Allison will launch the eGen Power 100D, capable of a 23,000 lb /10,400 kg gross axle weight ratio (GAWR), as the first electric axle variant within the eGen Power series of products.

The electric axles will be manufactured in Allison’s recently completed 110,000 square foot electric axle development and manufacturing facility in Auburn Hills, Michigan.

The company says the eGen Power 100D is one of the most powerful and fully integrated e-axle systems in the world for medium- and heavy-duty trucks. It features two electric motors capable of generating 200 kW of continuous power each, or 400 kW in total, with a peak combined power of 550 kW. The eGen Power 100D also integrates a two-speed transmission into the central housing.

The two-speed transmission facilitates a high starting gradeability, top speed and efficiency as well as an optional differential lock. This efficiency advantage translates to increased range capability or a reduction in battery pack size, optimising the economic value the eGen Power electric axles deliver.

“Allison is continuing to build our electrification product portfolio under the Allison eGen brand, and we continue to advance those products through collaborative validation programmes with leading truck original equipment manufacturers globally”, said Branden Harbin, managing director of global marketing at Allison Transmission. “Our promise to our customers is to provide the most reliable and valued propulsion solutions in the world to enable our customers to work more efficiently. We plan to continue to be a propulsion solution provider of choice, regardless of power source or propulsion type.”
