Weight reducing for Freightliner Cascadia

The Cascadia’s lightweight options include the powerful Detroit Diesel DD13® engine with the Detroit Diesel BlueTec® 1-Box™ Configuration, with a new ArvinMeritor aluminum carrier for the M-14X tandem rear axle; Steelite X30 brake drums; Hendrickson STEERTEK/AIRTEK axle and suspension; 11 1/8-inch Aluminum frame rails and aluminum air tanks; Michelin X One® rear tires and Alcoa forged aluminum wheels; and SAF-HOLLAND 12-inch aluminum air slide fifth wheel.

Optional aerodynamic enhancements designed and tested in Freightliner’s custom-built wind tunnel, include next generation chassis side fairings and 20-inch side extenders which further contribute to the Cascadia’s leadership position in fuel economy. These enhancements on display at the Mid-America Trucking Show provide up to 1.8 percent fuel economy improvement over current 72-inch raised roof models.
