2020 Freightliner CASCADIA – First SAE Level 2 Automated Truck in North America (CES 2019) - The Freightliner Cascadia is a heavy-duty semi-trailer truck and the flagship model of Freightliner. Its design took fuel efficiency into greater consideration, and several other features including the powertrain offerings, sound mitigation, safety systems, and overall mechanical reliability were improved from its predecessors. It is offered in three basic configurations: Day Cab, Mid-Roof XT, and Raised Roof. The latter two models are sleeper cabs, offered in various lengths ranging from 48 to 72 inches (Raised Roof models 60” or 72” lengths only). The Cascadia is sold chiefly in North America. Its place remains occupied by the Freightliner Century (no longer in US production) for export markets.
