Aerodynamic enhancements to the new Cascadia announced by Freightliner include Aerodynamic Height Control. Aerodynamic Height Control electronically lowers the suspension height at 55 MPH to optimize airflow over and under the front of the truck and reduce drag. Other enhancements include Michelin X Line D+ Energy tires developed in collaboration with Michelin, which reduce rolling resistance in 6×4 applications, and a low ground clearance bumper.

Another critical component of the new Cascadia’s performance is its Integrated Detroit Powertrain, a combination of a proprietary heavy-duty engine, transmission, and axle that the company says is designed to seamlessly work together for maximum efficiency. The integrated powertrain features Intelligent Powertrain Management 6, which uses the truck’s kinetic energy to automatically adjust to the truck’s surroundings by reducing braking power and making transmission and engine adjustments, saving fuel and reducing wear and tear on components.

For fleets concerned with fuel economy, Detroit Connect Analytics will also introduce new Intelligent Powertrain Management reporting capabilities, and the fuel analysis will indicate if the vehicle is using Aerodynamic Height Control.
