Aerodynamic enhancements to the new Cascadia include Aerodynamic Height Control. An industry first, 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 powerful combination of a proprietary heavy-duty engine, transmission, and axle that 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.
Thanks to DTNA’s significant investment in ongoing R&D in aerodynamics, powertrain development and systems intelligence, the new Cascadia delivers a 35% improvement in fuel efficiency compared to the first Cascadia introduced in 2007. This equates to annual savings of up to 4,700 gallons of fuel per truck, which is the amount of fuel consumed by six typical family cars in a year.
