Allison Bus e-Axle (ABE)

Allison Transmission is introducing the new ABE Series, a line of fully-integrated electric axles designed to fit double-decker buses, low-floor city buses, non-low floor buses and articulated buses, replacing the vehicle’s traditional powertrain system. Available in single speed and 2-speed options, the ABE Series is a bolt-in solution that features electric motors, power electronics, a multi-speed gearbox, oil cooler and pump. The ABE Series axles are capable of operating without restrictions at regular highway speeds and on all allowable grades, making our ABE Series electric powertrain system the most efficient and powerful solution for bus fleets today.
