Western Star is an American truck manufacturer headquartered in Portland, Oregon. It is owned by Daimler Truck North America, which is a subsidiary of German automotive manufacturer Daimler Truck AG. Western Star trucks are commonly sold at Freightliner dealerships and is generally marketed as a more premium compared to Freightliner.
In 1967, White Motor Corporation started the Western Star division as White Western Star with a new plant at Kelowna, British Columbia, sharing headquarters with White in Cleveland, Ohio. White Western Star trucks in that era typically used cabs from its sister company, Autocar. Western Star production was moved to Ogden, Utah, but the brand was not included in the 1981 sale of White's truck business to Volvo, instead being sold to Bow Valley Resources and Nova Corporation, each owning 50%.
In 1991, Western Star Trucks was purchased by the owners of the Western Star Australian subsidiary, Terry Peabody and Bob Shand. Western Star Trucks acquired the bus manufacturer Ontario Bus Industries (renamed Orion Bus Industries) in 1995. ERF trucks was purchased by Western Star in 1996. It was sold in 2000 to MAN.
In 2000, Western Star was purchased by DaimlerChrysler, becoming part of the Freightliner Trucks division.
In 2002, Western Star production was moved to a plant in Portland, Oregon. In May 2015, the Daimler Truck North America plant in Cleveland, North Carolina, began to build 4700 and 4900 models, as well as assemble all new semi tractor 5700XE models.
In 2022, Western Star announced and released the X Series of trucks to market, replacing the then current "Constellation" Series which had been in production since 1998/99. The new X series of Western Star trucks includes; 47X, 48X (Australia only), 49X and 57X.
The 47X is the entry-level model, used mostly for vocational purposes, such as adding a dump bed or cement mixer. The 47X can also be used with a standard fifth wheel connector to tow standard trailers. The 47X is available in a day cab configuration, along with 36â³ and 48â³ sleeper options.
The 49X is also a vocational truck, that is a bit more heavy duty and has more customizability. The 49X is available as a standard semi and extra attachments can be added. The 49X is available in multiple cab configurations, including day cab, 36â³ sleeper, 48â³ sleeper, 60â³ sleeper and 72â³ sleeper. The 36â³ is a trench style low roof, while the 48â³ and 60â³ are available in mid roof. The 72â³ is available in high roof and mid roof.
The 57X is the on-highway variant which uses a Freightliner Cascadia chassis and cab but has many improvements such as reinforced cabin bones, different doors, and an aerodynamic front end with two stage heated headlights and stainless steel chrome grille. It also implements a digital cockpit as standard equipment. Customers still can opt for a standard analog dashboard. It is designed as on-highway semi truck capable of towing semi trailers, with few to no vocational applications. The 57X is a more premium model than its vocational counterparts. Every 57X is hand-built in Cleveland, North Carolina. The 57X comes in multiple configurations, including day cab, and 60â³ mid roof and 72â³ high roof sleeper options.
Available transmissions are Automated Manual DT12 in different specifications and Eaton Automated Manual/Manual gearboxes.
