Alternative Fuels

Allison fully automatic transmissions can accommodate many diesel-alternative fuel sources including gasoline, natural gas, propane, hydrogen fuel cell and battery electric. 

Fuel Agnostic Propulsion

Alternative fuels have emerged as a strong solution for OEMs and fleet customers looking to reduce emissions and prepare for upcoming changes to regulatory standards. Allison’s propulsion solutions are fuel agnostic, meaning they can pair with several energy sources, and in some cases, elevate the performance of vehicles powered by alternative fuels. This provides customers with the power of choice in selecting the energy source that best suits their needs. 

The Fully Automatic Difference

Our patented torque converter multiplies engine torque at launch, enabling peak performance and fuel efficiency. Unlike manuals and AMTs, Allison automatics maintain seamless, full-power shifts, allowing vehicles to travel farther in less time. This empowers fleets to use familiar hardware to achieve sustainability goals without sacrificing productivity and efficiency.

Exploring Alternative Fuel Solutions

Our torque converter multiplies engine torque to greatly improve startability, drivability and productivity to compensate for the lower power associated with Natural Gas. This technology also supports the engine during frequent start-stop duty-cycles, which promotes peak fuel efficiency and reduces emissions to support the environment through cleaner air.
