Prevost / Nova Bus to Offer Next Gen FuelSense from Allison Transmission

| February 9, 2018


Prevost / Nova Bus announced that it will offer FuelSense® 2.0 featuring DynActive™ Shifting — a  fuel-saving technology from Allison Transmission that is designed to deliver up to 6 percent additional fuel savings beyond the company’s original FuelSense software.

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. Available in three packages, FuelSense 2.0 uses a learning algorithm to continuously find the ideal balance of fuel economy and performance.

“Much of Allison’s success has come from building transmissions tailored to specific applications rather than a one-size-fits-all approach,” said Heidi Schutte, vice president of marketing and sales for the Americas with Allison Transmission. “With FuelSense 2.0, we’ve taken this customization to a new level, giving vehicle builders more flexibility to offer the right blend of performance and fuel economy for their specific application.”

With more than 3 million test miles in customer fleets representing a variety of duty-cycles, the fleets have experienced fuel economy gains up to 4 percent in transit buses and up to 6 percent in other vocations. This fuel economy improvement in transit buses resulted in an estimated annual per vehicle savings of up to $800 based on duty cycle, annual mileage and fuel price.

FuelSense 2.0 Max includes enhanced Acceleration Rate Management and delivers the following:

  • 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. Optional Neutral at Stop with Coast Mode allows attainment of neutral at very low speeds as the vehicle comes to a stop using the service brakes.
  • 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.
