Allison Transmission announced FuelSense 2.0 transmission software, featuring DynActive Shifting, which the company says adds up to 6% additional fuel savings beyond the original FuelSense software.

FuelSense 2.0 is available in three packages to allow fleets to optimize fuel economy and performance for their specific needs, Allison announced at the NTEA's Work Truck Show in Indianapolis.

"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."

The original FuelSense was introduced in March 2014 and was designed to enable fuel economy improvements for vehicles with Allison transmissions. FuelSense 2.0 uses DynActive Shifting to provide an infinitely variable combination of shift points, according to Allison. The new version uses a learning algorithm to continuously search for the ideal balance of fuel economy and performance.

FuelSense 2.0 is especially suited for refuse, construction, distribution, and bus applications, according to the company.

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.

Neutral at Stop lowers fuel consumption and emissions by reducing or eliminating the load on the engine when the vehicle is stopped. It is available in two versions: Standard and Premium. Standard provides partial (first-level) Neutral at Stop and 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 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.

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. FuelSense 2.0 packages will be available beginning in mid-April. For more information, visit allisontransmission.com/fuelsense.
