Western Star 5700 Trucks

We've made extreme trucks for years. Now we've done the same for efficiency.

When we decided to build a fuel efficient truck, we took that efficiency to the extreme. Every feature and component of this truck was refined to get maximum aerodynamics, efficiency 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. Check out the features to get part of the story, then find your nearest dealer to get the rest.
