Freightliner Trucks said its Cascadia model can now be spec’d with the new AeroSmart and SmartAdvantage Powertrain packages, both options designed to enhance the efficiency and performance of this popular Class 8 tractor.
The new AeroSmart package allows the latest aerodynamic components available for the Cascadia to be easily combined with the SmartAdvantage powertrain. Customers will be able to quickly spec and order the best aerodynamic package for their business, to help them achieve the best fuel economy possible.
Developed by Cummins and Eaton, the SmartAdvantage optimized powertrain improves fuel economy by 1.5 percent when compared to a truck spec’d with a Cummins ISX15 engine and Eaton UltraShift PLUS LAS transmission.
The SmartAdvantage powertrain combines the power of the Cummins ISX15 with SmartTorque2 with the smooth shifting of the Eaton Fuller Advantage 10-speed automated transmission. The engine and transmission share critical data to determine the torque required to deliver the right power, resulting in a more efficient performance.
Available exclusively with the SmartAdvantage Powertrain, the Cummins ISX15 with SmartTorque2 is ideal for on-highway applications. Higher torque is delivered earlier in the RPM range, enabling trucks to cruise at 1,150-1,240 rpms while still maintaining the torque and power needed.
The transmission also includes new features, such as the use of lightweight components and precision lubrication. Small gear steps enable downspeeding in overdrive and efficiency in direct drive, and optimized shifting is based on grade, vehicle weight, engine torque and throttle position. Fuel economy is further enhanced through the lubrication design, which reduces churning losses and eliminates the need for a cooler in most applications.
The AeroSmart and SmartAdvantage powertrain packages are now available to order.
