Born from the driver’s need for increased efficiency, safety, and comfort. Purpose-built to redefine what a highway truck should be.
THE TRILOGY OF TOUGH
IS NOW COMPLETE
Introducing the 57X, the newest member of the Western Star X-Series family and the most advanced and driver-focused highway truck we’ve ever built.
Built on a history of toughness and equipped with technology, comfort, safety and efficiency that rewards you every time you get behind the wheel and when you check your bottom line.
The Most Driver-Focused Truck On The Road
Making life easier for those who drive our trucks is always high on the priority list, so we’ve taken cab life a serious leap forward. It begins with our new digital dash display: bright, clear, customizable and intuitive. Then there’s the driver’s lounge in back. Equally as customizable, it’s easily spec’d out with optional features including a flat-screen TV, refrigerator, dinette, a full-size Murphy-style bed and more.
Efficiency (Aerodynamics and Powertrain)
Advanced Aerodynamics And Greater Fuel Efficiency
We’ve pushed the laws of aerodynamics to the max and these advancements, coupled with the latest powertrain technologies, have come together seamlessly to deliver the most fuel-efficient highway truck we’ve ever made.
Created To Make Driving Easier

More Data Means More Uptime
Our X-Series trucks represent a big advancement in productivity for Western Star trucks thanks to Detroit Connect®. Detroit Connect translates the performance data of any type of truck into real-time information you can use to make decisions that can help you keep those trucks on the road and earning.
Engineered To Perform
The 57X rides on a durable Daimler corporate chassis, backed by millions of miles of proven performance.
Engineered For The Long Haul
Steel-reinforced aluminum with internally mounted hinges for greater durability and no sagging.
Form And Function Working Together
Our C-Bar Mirror System was created for maximum stability and aerodynamics to help your drivers and your bottom line.
Safety and technology as advanced as its design.
From anticipating traffic slowdowns to protecting blind spots to keeping trucks in their lanes, Detroit Assurance® Suite of Safety Systems has the technology to help improve safety and uptime.
The 57X comes equipped with the entire Detroit Assurance® Suite of Safety Systems, the most advanced safety technology in the industry. The suite features a number of safety-improving technologies, which you can learn more about right here.
Active Brake Assist 5 detects distance and speed to moving and stationary objects in its path and determines if braking is necessary. It’s the only system on the market that works down to 5 MPH*, making it ideal for travel in congested urban areas. It also recognizes pedestrians who are about to cross in the truck’s path, alerting the operator while partially braking, followed by full braking if the operator does not react.
*with Detroit® DT12® transmission
Detroit Assurance technology enables state-of-the-art features such as Adaptive Cruise Control to 0 MPH to ease driving in stop-and-go traffic, as well as help mitigate front and rear collisions.
Whether stopped in heavy traffic or for any other reason, this state-of-the-art feature can keep a truck* stopped when the driver removes their foot from the brake. Brake Hold Mode can be engaged by pressing the brake pedal all the way down. It automatically disengages when the driver accelerates.
*with DT12 Transmission
Lane Keep Assist reads and tracks lane markers to help drivers keep their trucks centered in their lane.
This safety feature detects when a truck drifts out of its lane and then actively steers it back on course.
A game changer for safety, Side Guard Assist detects objects on the passenger side of the truck and alerts the operator.
This industry leading technology detects and actively prevents the truck from making a right turn into moving cyclists and pedestrians in urban situations.
