Allison Transmission says it has developed a new fuel-efficiency package that can improve fuel mileage by 20%.
The FuelSense package will initially be offered in the Freightliner M2 106 medium-duty truck. The system automatically adapts shift schedules and torque based on load, grade and duty-cycle, according to the company.
"Fuel prices have nearly doubled since the mid-2000s, and fleet owners need solutions," said Michael Headly, senior vice-president, global marketing, sales and service for Allison Transmission. "They want straightforward fuel economy, without compromising overall fleet performance and productivity. With FuelSense, Allison delivers the best of both worlds."
Features include: fifth generation smart controls, acceleration management and a precision inclinometer; EcoCal shift technology that keeps engine speed at the most efficient level; dynamic shift sensing to automatically sense when low engine speed shifts can be made; and 'neutral-at-stop' to save fuel when the truck is stationary.
Allison says it achieved the 20% fuel savings during testing and in simulations. The features have already been incorporated into Allison's TC10 automat transmission for tractors. Freightliner will be the first OEM to offer the new package, beginning in late 2014 in M2 chassis equipped with Allison 2000 and 3000 series transmissions.
"We are proud to be the first to offer this innovative solution to customers," said Mary Aufdemberg, director of product marketing for Freightliner. "Our customers demand a lot from our trucks, so we set our standards high. We value our relationship with Allison and have a common commitment to maximizing the performance of work trucks and the profits of the businesses that depend on them."
Freightliner will pair the Allison FuelSense package with the Cummins ISB6.7 engine.
"When packaged together, our new options result in a smart business solution that contributes to fuel efficiency, as well as driver satisfaction," said Aufdemberg. "In addition to performance features, we've bundled some of our most popular exterior appearance, comfort and convenience options that drivers will appreciate during their long hours behind the wheel."
