History of Freightliner
Freightliner began in Portland, Oregon, in 1929 as the truck manufacturing division of Consolidated Freightways. It became Freightliner Corporation in 1942. Founder Leland James transformed the trucking industry by hiring engineers to build components from lightweight aluminum rather than steel, which was the industry norm at the time. Although the idea faced skepticism early on, Freightliner ultimately gained wide acceptance and continues to lead in innovation and performance.
The Eastern Freightliner launched in 1950 with the B42 tractor, which hauled a single 35-foot trailer. This model introduced the first transcontinental cab-over sleeper and sold for $15,871. In 1952, Freightliner released the WF64, which featured the first overhead sleeper for long-haul applications and ran on gasoline, diesel, or liquefied propane. A year later, the four-wheel-drive Mountaineer tractor hit the market, improving traction for on- and off-highway conditions, particularly in snowy mountain passes.
In 1981, Daimler-Benz acquired Freightliner, making it part of Daimler Truck North America (DTNA). DTNA became a publicly traded company in 2021 after separating from Daimler AG.
Specifications
Freightliner introduced the original Cascadia in 2007 as its flagship line, equipped with the Detroit DD15 engine and focused on fuel efficiency, aerodynamics, safety, and driver comfort. The second-generation “Evolution” series launched in 2012, improving fuel efficiency with the Detroit DT12 Automated Manual Transmission (AMT). Since then, Freightliner has added new technologies, safety features, and aerodynamic enhancements.
The 2025 Cascadia offers the Detroit DD13 engine with 370 to 525 horsepower and 1,250 to 1,850 lb.-ft. of torque. The DD15 provides 435 to 505 horsepower and 1,550 to 1,850 lb-ft. of torque.
Freightliner will soon offer the Cummins X15, delivering 400 to 525 horsepower and 1,450 to 1,850 lb.-ft. of torque, and the Cummins X15N, which offers 400 to 500 horsepower and 1,450 to 1,850 lb.-ft. of torque.
Transmission options include the Detroit DT12 On-Highway 12-speed AMT series—DT12-HE, DT12-H, and DT12-HL—as well as the Eaton Cummins Endurant 12-speed.
