Allison Transmission announces results testing

Allison Transmission has announced results of certified, third-party testing that proves its fully automatic Allison 2500 with FuelSense technology provides 5% better fuel economy than the Eaton Procision dual clutch transmission.

Assuming 50 000 miles per year at 7 mpg and US$2.60/gal., fleet operators can annually save at least US$900 in fuel per vehicle by choosing an Allison Automatic with FuelSense over the Eaton Procision.

Aside from the different transmissions, two equally spec'd Class 7 trucks were tested by an independent facility in west Texas. The testing used the independent September 2015 revision of the SAE J1526 SAE Fuel Consumption Test Procedure (Engineering Method). This method has been specifically developed for the trucking industry to analyse fuel consumption on two of the most common duty-cycles: the ARB Heavy Heavy-Duty Diesel Truck (HHDDT) cycle and the ARB Urban Dynamometer Driving Schedule (UDDS) cycle.

These duty-cycles are typical of distribution, school bus or general purpose use for medium-duty vehicles.

To ensure consistency, drivers drove the vehicles at the same speeds and switched vehicles through multiple testing phases.

Vehicles ran 36 HHDDT and 24 UDDS cycles to ensure the fuel economy difference with over 95% confidence.

FuelSense components automatically adapt shift schedules and torque to maximize transmission efficiency based on load, grade and duty cycle – without sacrificing the Allison performance and Continuous Power Technology™ benefits on which fleets already depend.
