Allison Transmission announced FuelSense® 2.0 featuring DynActive™ Shifting, delivering up to 6% additional fuel savings beyond the company’s original FuelSense software. Available in three packages, FuelSense 2.0 allows fleets to optimize fuel economy and performance to their specific needs.


“This latest technology further reduces fuel consumption in all segments of a vehicle’s duty cycle,” said Heidi Schutte, Vice President of Marketing and Sales for the Americas with Allison Transmission. “FuelSense 2.0 offers increased specification flexibility and delivers the best economic value to our customers.”


Introduced in March 2014, Allison’s FuelSense packages enabled significant fuel economy improvements. Through a set of proprietary software enhancements, the new FuelSense 2.0 technology uses DynActive Shifting to provide an infinitely variable combination of shift points. FuelSense 2.0 uses a learning algorithm to continuously find the ideal balance of fuel economy and performance.


Providing maximum value for applications with heavy start-stop needs, FuelSense 2.0 is ideally suited for city bus, school bus, refuse, construction and distribution. With nearly 3 million test miles in customer fleets representing a variety of duty cycles, the fleets have experienced fuel economy gains up to 6%. This fuel economy improvement resulted in estimated per vehicle savings of $300 – $900 annually based on application, annual mileage and fuel price.


The available packages are FuelSense 2.0, FuelSense 2.0 Plus and FuelSense 2.0 Max; all three include DynActive Shifting. FuelSense 2.0 Plus and Max include improved “Neutral at Stop.” FuelSense 2.0 Max includes enhanced acceleration rate management.


  • Improved Neutral at Stop—This feature lowers fuel consumption and emissions by reducing or eliminating the load on the engine when the vehicle is stopped. Two versions are available: (1) Standard, which provides partial (first-level) Neutral at Stop, or (2) Premium, which provides 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—This feature mitigates aggressive driving by automatically controlling engine torque. Newly updated, in addition to the 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. For more information, visit Currently, aftermarket installation of FuelSense 2.0 is not allowed in California or the CARB Heavy Duty Opt-In states of Maine, Pennsylvania and New Jersey.
