The Freightliner Cascadia is now available with the AeroSmart and SmartAdvantage Powertrain packages designed to enhance efficiency and performance.

The AeroSmart package combines all of the aerodynamic components available for the Cascadia with the SmartAdvantage powertrain. 

The SmartAdvantage powertrain was developed by Cummins and Eaton and is designed to improve fuel economy by 1.5%. SmartAdvantage combines a Cummins ISX15 engine with SmarTorque2 with an Eaton Fuller Advantage 10-speed automated manual transmission.  

Freightliner said the engine and transmission share critical data with each other to determine the torque required to deliver the correct power, resulting in more efficient performance.

The Cummins ISX15 with SmarTorque2 works well for on-highway applications. The engine delivers higher torque earlier in the RPM range enabling trucks to cruise at 1150-1240 RPM while still maintaining sufficient torque and power, said the OEM.

The Eaton transmission has new features such as precision lubrication and lightweight components. The lubrication design reduces churning losses and eliminates the need for a cooler in most applications which improves fuel economy.

Small gear steps enable downspeeding in overdrive and improved efficiency in direct drive and shifting is optimized based on grade, weight, engine torque and throttle position.

The AeroSmart and SmartAdvantage powertrain packages are now available to order.
