Allison Truck e-Axle (AXE)

Allison Transmission is introducing the new AXE Series, a line of fully-integrated electric axles designed to fit Between The Wheels™ of heavy-duty trucks and buses, replacing the vehicle’s traditional powertrain system. Unlike many other electric powertrain systems today, the AXE Series is a bolt-in solution compatible with the current vehicle frame, suspension, wheel-ends and OEM vehicle assembly process. The AXE Series features fully-integrated electric motors, a multi-speed gearbox, oil cooler and pump, providing the highest performance and efficiency in the industry. Our system is compatible with full battery electric vehicles (BEV), fuel cell range extender electric vehicles (FCEV), internal combustion engine (ICE) or turbine generator range extenders (REV).
