MPG Fuel Efficiency Packages Now Include Aerodynamics and Powertrain

LISLE, Ill. (March 11, 2019) – To simplify the process of spec’ing a vehicle for optimal fuel efficiency, International Truck introduces Powertrain Packages to its International® LT® Series MPG Fuel Efficiency Packages. Powertrain Packages are now available for the International® A26 and Cummins® X15 engines in direct-drive and overdrive offerings.

The MPG Fuel Efficiency Powertrain Packages combine exceptional engine ratings with the lightweight Eaton Endurant™ transmission, predictive cruise control, high efficiency rear axles, and rear axle ratios as low as 2.15 for optimal fuel economy.

“Improving fuel efficiency is a major opportunity for a fleet to reduce its Total Cost of Ownership,” said Jim Nachtman, director, heavy-duty, Marketing, Navistar. “We took a holistic approach when developing the MPG Powertrain Packages – from the engine and transmission, to the rear axles and lubricants – to easily maximize fuel efficiency.”

The MPG Fuel Efficiency Packages will soon include a second Aerodynamic option available for the International LT Series day cab, 56-inch hi-rise and 73-inch hi-rise/sky-rise cab models, which will be available for order this spring. The new highest-efficiency spec incorporates proprietary and supplier-provided enhancements included in the first Aerodynamic Package, as well as predictive cruise control and aerodynamic drive wheel fairings.

 “With so many fuel-efficient technologies available, the spec’ing process can be daunting,” adds Nachtman. “Through our MPG Fuel Efficiency Aerodynamic and Powertrain Packages, we’re making it easier than ever for fleets to enhance performance while reducing Total Cost of Ownership.”

The International LT Series MPG Fuel Efficiency Packages, including the new Aerodynamic Package, will be displayed at the International booth #623 at ATA’s TMC 2019 Annual Meeting & Transportation Technology Exhibition, March 18-21, 2019. Learn more about International Truck fuel efficiency at
