International Truck has added Powertrain Packages to the LT Series MPG Fuel Efficiency Packages, designed to maximize fuel efficiency.

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 efficient engines with the lightweight Eaton Endurant transmission, predictive cruise control, high-efficiency rear axles, and rear axle ratios as low as 2.15 for improved 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.
