Navistar Inc. says it is now offering Allison Transmission's FuelSense fuel-efficiency package on its medium-duty and vocational International trucks. FuelSense is already available in Allison's 3000 and heavy-duty 4000 series transmissions, and the package is rolling out for the 1000 and 2000 series later this year.
‘This is a great option for customers who operate in high-density city environments or have demanding start and stop duty cycles and seek fuel economy improvements and cost savings,’ says Steve Gilligan, Navistar's vice president of product and vocational marketing. ‘We have seen FuelSense perform well in the International ProStar with the Allison TC-10 transmission, and we are excited to now include this as an option on our medium-duty and vocational products.’
FuelSense features a number of proprietary technologies, including smart controls, acceleration management and a precision inclinometer; EcoCal shift technology to keep the engine speed at the most efficient level; Dynamic Shift Sensing to automatically sense when low-engine-speed shifts can be made; Neutral at Stop to eliminate the load on the engine when the vehicle is stopped to reduce fuel consumption and reduce emissions; and Acceleration Rate Management to relegate engine power to match acceleration curves and control engine torque.
The company notes that FuelSense cuts fuel consumption by up to 20%, depending on the duty cycle and application.
