International Trucks is now offering an International LT Series MPG Package for Fuel Efficiency, the company announced at the American Trucking Associations’ Management Conference and Exhibition in Austin, Texas.
"At a time when every 1% improvement in fuel efficiency can save customers hundreds of dollars per truck per year, this new fuel efficiency spec package can help customers achieve major reductions in their [total cost of ownership]," said Michael Cancelliere, Navistar president, Truck and Parts. "In addition to savings from fuel efficiency, the LT Series MPG Package provides customers with upfront savings through cost-effective bundling of a range of aerodynamic, fuel-saving features."
According to Cancelliere, the LT MPG Package's highest-efficiency spec offers proprietary and supplier-provided enhancements, including an aerodynamic chassis package, predictive cruise control, air dam and bumper seal, as well as a roof fairing and extenders, chassis skirts and energy-efficient wheel covers. This spec delivers up to an 8% improvement in fuel efficiency over the International LT Series with just the roof fairing and extenders, air dam and bumper seal.
"Spec'ing for fuel efficiency can be a complex process," Cancelliere said. "The LT MPG Package simplifies that process while reducing customer TCO."
The International LT Series MPG Package is available in day cab, 56-inch hi-rise and 73-inch hi-rise/sky-rise cab models.
Package Includes FlowBelow Quick Release Wheel Covers
Part of the package is new FlowBelow Quick Release aerodynamic wheel covers. The wheel cover design provides instantaneous and tool-free access to the wheel end via a patented ‘push and turn’ quick-release latching system. In a related announcement, FlowBelow announced that its Quick-Release’Wheel Covers are now offered as a factory option on all International LT and RH Series trucks.
“The new International LT and RH Series have proven to be some of the most technologically advanced, fuel efficient trucks available,” said Josh Butler, founder and CEO of FlowBelow Aero. “With the addition of the FlowBelow Products on-highway LT and RH Series trucks, we are providing fleets with even higher fuel efficiency while reducing total cost of ownership.”
