History of the Freightliner Cascadia

Launch and Cascadia Evolution

The Cascadia is Freightliner’s long-haul tractor and was developed around low fuel consumption, with improvements to the powertrain, noise, safety systems and mechanical reliability over earlier trucks. It comes in three basic configurations: Day Cab, Mid-Roof XT and Raised Roof, the last two being sleepers with lengths from 48 to 72 inches; the Raised Roof is offered only in 60 or 72 inches. In 2013 Freightliner released the Cascadia Evolution, a more efficient version with better aerodynamics and a redesigned instrument cluster, improved seat and lumbar support, repositioned dashboard switches with larger contrast lettering, and an optional battery-powered auxiliary HVAC unit from Thermo King that cut overnight idling.

2017 facelift

For the 2018 model year the Cascadia received a major revision. The body was largely unchanged apart from new chassis fairings and longer cab extenders, while outside there was a more sculpted hood cowl, a redesigned bumper, a larger grille, all-LED headlights, more aerodynamic hood mirrors and improved bumper air dams. Inside came a new dashboard, more ergonomic seats, a larger bunk, redesigned storage and dimmable LED ceiling lights. An optional driver’s loft added a collapsible table and two folding seats that stow under an extra-wide Murphy-style bunk. Freightliner also offered its own battery-powered HVAC unit beside the Thermo King systems, and the truck gained the Detroit DT12 automated manual transmission, quiet door and window seals, LED marker and tail lights and a suite of active and passive safety systems.

eCascadia

The battery-electric eCascadia was tested in 2019, when the first two trucks went to customers in California, Penske for regional traffic in Southern California and NFI for drayage at the ports of Los Angeles and Long Beach. Order books opened in 2021, one order covering 800 trucks, and after a prototype covered more than a million miles, production and the official premiere took place in May 2022. The long-range version offers 230 miles with a single drive axle or 220 miles with a tandem, from 438 kWh batteries, with 320 to 470 hp and charging to 80 percent in 90 minutes, and a gross combination weight of up to 82,000 lb.
