Allison Transmission announces 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.
Introduced in March 2014, Allison’s FuelSense packages enabled 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 percent. This fuel economy improvement resulted in estimated per vehicle savings of $300 to $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 – Provides partial (first-level) Neutral at Stop, or (2) Premium – 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 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.
