Western Star 5700XE
When we decided to build a fuel-efficient truck, we took that efficiency to the extreme. Every feature and component in the Western Star 5700XE was refined to get maximum aerodynamics and dependability, and we did it without sacrificing the kind of looks that let everyone know this aerodynamic truck is every bit a western star.
Western Star has a long history of ruggedness, dependability, and hand-built factory customization that most manufacturers can only hope to match. And like all our Western Star trucks, the all-new Western Star 5700XE is manufactured right here in the United States.
