Freightliner showcased three Cascadia models at the recent Mid America Trucking Show that feature lightweight specs and fuel-efficient options. Plus enhanced aerodynamic features on all models, whether a large sleeper for long-haul dry van applications, a mid-roof sleeper for bulk deliveries, or a day-cab for regional hauls.

The Cascadia’s lightweight options include the Detroit Diesel DD13 engine, a new ArvinMeritor aluminum carrier for the M-14X tandem rear axle; Steelite X30 brake drums; Hendrickson Steertek/Airtek axle and suspension; aluminum frame rails and aluminum air tanks; Michelin X One rear tires and Alcoa forged aluminum wheels; and SAF-Holland aluminum air slide fifth wheel. As well as a wide selection of lightweight sleeper options.

Optional aerodynamic enhancements include next-generation chassis side fairings and 20-in. side extenders, claimed to provide up to 1.8% better fuel economy over current 72-in. raised-roof models. Previously introduced improvements include the roof deflector, chassis skirts, valence panel and bumper with closures.
