Allison FuelSense 2.0 Claims Added Fuel Economy

March 14, 2017

Allison Transmission has announced FuelSense 2.0 featuring DynActive Shifting, delivering up to 6 percent additional fuel savings beyond the company’s original FuelSense software, introduced in 2014 and now chosen by more than half of Allison buyers.

Through a set of proprietary software enhancements, the FuelSense 2.0 option provides an infinitely variable combination of shift points. A learning algorithm continuously finds the ideal balance of fuel economy and performance.

Tests with dump trucks show the advanced features show a 2 percent gain in fuel economy, saving more than $300 per year for a typical truck, said Ryan Milburn, executive director for embedded controls.

Three available packages are FuelSense 2.0, FuelSense 2.0 Plus and FuelSense 2.0 Max, all with DynActive Shifting. FuelSense 2.0 Plus and Max include improved Neutral at Stop. FuelSense 2.0 Max includes enhanced Acceleration Rate Management. Customers can tune the controls for maximum economy, maximum performance or anything in between.  Among features:

  • Improved ‘Neutral at Stop’ – Lowers fuel consumption and emissions by reducing or eliminating the load on the engine when the vehicle is stopped. Two versions are available: Standard, providing provides partial (first-level) Neutral at Stop, and Premium, with full Neutral at Stop and a new, low-speed coasting capability. Both versions feature a locked output at stop to prevent rollback.
  • Enhanced ‘Acceleration Rate Management’ – Mitigates aggressive driving by automatically controlling engine torque. Newly updated, in addition to five levels of control currently available, it provides more precision by limiting vehicle acceleration to a customized rate.

FuelSense 2.0 packages will be available beginning in mid-April. FuelSense 2.0 can be programmed into Allison transmissions with Generation 5 or later electronic controls, except in California and CARB-opt-in  states of Pennsylvania, Maine and New Jersey.

Autocar is the first truck builder that will use FuelSense 2.0 for its trash-collection trucks, the company said. Autocar also makes chassis for concrete pumpers. More information is at
