IAA 2024, Allison Transmission to showcase new automatic transmission and fully electric axle family

Allison Transmission will participate in IAA 2024, the major European exhibition to be held in Hannover from 17 to 22 September. The manufacturer will showcase the new 9-Speed fully automatic transmission and the latest addition to the patented Allison eGen Power family of fully electric axles, the 85S axle. Allison will also cover its activities and investments in future technologies and ventures.

Allison’s eGen Power 85S

Allison’s eGen Power 85S extends its family of fully electric axles, initially introduced in 2020. eGen Power axles replace the traditional drivetrain of a vehicle and are compatible with fully battery electric vehicles, fuel cell electric vehicles and hybrid applications, providing 100% of motor torque during regenerative braking. These axles provide a drop-in solution that seamlessly integrates into existing vehicle chassis, offering significant space savings for battery storage. The eGen Power 85S features a high-speed electric motor and a two-speed gearbox. With a continuous power output of 225 kilowatts (kW) and a peak power of 325 kW, it delivers high acceleration and speed. Allison’s eGen Power 85S has been successfully integrated into Anadolu Isuzu’s Novo VOLT fully electric midi bus platform and will be integrated into their light-duty truck for refuse and distribution.

In addition, all Allison fully automatic transmissions are compatible with alternative fuel engines such as compressed natural gas (CNG) and biogas and are compatible with electric motors and hydrogen technology. This enables fleets to reduce emissions from their internal combustion engine vehicles.

The new 9-Speed fully automatic transmission

The new Allison 9-Speed transmission is engineered to meet the needs of commercial vehicles that operate in frequent stop-and-go cycles, offering increased uptime, improved fuel economy, high performance and low maintenance costs. The 9- Speed builds on the proven durability of the Allison 2000 Series™ 6-speed transmission, which has accumulated more than 100 billion miles globally. It’s designed to utilize the same vehicle manufacturer interfaces as its 6-speed predecessor, providing ease of integration into vehicles currently equipped with the Allison 2000 Series.

“The new Allison 9-Speed transmission offers superior performance and engine torque for applications up to 1,200 newton-meters,” said Trond Johanson, Director European Sales, Allison Transmission. “With the transition from six gears to nine gears, there is an improvement of over 50% in gear ratio due to a wider gear ratio coverage and smaller gear steps compared to an eight- or six-speed transmission, which results in higher performance and lower fuel consumption.”
