Western Star in August 2022 rolled out the third model in its X-Series lineup – the on-highway 57X.
Since its 2020 pivot to become Daimler Truck North America's vocational brand, Western Star has launched models 49X and 47X but the 57X marks an about-face from the jobsite.
The 57X replaces the 5700XE – Western Star's first foray into aero market that debuted in 2014 and starred as Optimus Prime in the Transformer franchise that same year. The model 5700XE was discontinued at the end of last year.
The 57X is the most fuel-efficient model Western Star has ever built – 5.8% more fuel-efficient than its predecessor. About half of those gains come from an aerodynamic retooling and the other half from a powertrain comprised exclusively of Detroit products.
