Western Star Introduces All-New 57X

New truck is Western Star’s most advanced on-highway vehicle

Western Star today introduced the latest addition to its X-Series, the all-new Western Star 57X. The on-highway truck joins the new Western Star 47X and 49X to complete a lineup purpose-built for toughness, productivity and efficiency.

“With the addition of the 57X, Western Star’s new X-Series now rises to the next level,” said David Carson, senior vice president, sales and marketing, Daimler Truck North America (DTNA). “While the 47X and 49X serve the vocational customer, the 57X was conceived, designed and engineered specifically for owner-operators an d small fleets looking for a truck that provides the safety, efficiency, durability and prestige that only Western Star can deliver.”

Reaches new heights in efficiency

The 57X is the most fuel-efficient truck Western Star has ever built. It is 5.8 percent more fuel-efficient than its predecessor, the 5700XE, while delivering legendary Western Star dependability and productivity.

The 57X gives owners a choice of Detroit engine models. The DD13 Gen 5, DD15 Gen 5 and DD16 engines all deliver proven maximum on-highway performance and fuel economy.

The 57X is available with Detroit Powertrain components including Detroit DT12 Direct or Overdrive AMT transmissions, which reduce fuel consumption and increase efficiency while improving shifting and reducing wear. Intelligent Powertrain Management anticipates terrain and adjusts to road conditions to further maximize efficiencies. Available Detroit front steer and high-speed ratio rear tandem axles also contribute to fuel efficiency and performance while reducing maintenance.

The powertrain efficiency is complemented by new aerodynamic improvements to the cab and chassis that help the 57X log mile after mile with less fuel consumption:

• New aerodynamic hood and bumper with air ducts.

• Roof and chassis fairings for the Day Cab, 60-inch and 72-inch Mid Roof.

• Chassis side fairings with flexible skirts specifically designed to fill the gaps between cab and chassis.

• Aerodynamic roof fairing or adjustable aerodynamic deflector for day cab.

• 24-inch sleeper side extenders (12-inch for day cabs).

• Optimized drive wheel fairings smooth the air flow as it passes the trailer.

• FlowBelow mold-in color drive wheel covers.

Equipped with best-in-class technology

The new 57X is equipped with industry-leading safety and connectivity features designed to protect the driver, pedestrians and other motorists, while providing the operator with crucial, real-time information about the vehicle which helps minimizing insurance costs and downtime fixing accident related repairs.

It comes standard with the best-in-class Detroit Assurance 5.0 safety system with Active Brake Assist 5, an always-on system that fuses camera and radar technology to detect moving obstacles in front of the truck and can deploy full braking. With Detroit Assurance also comes Adaptive Cruise Control (ACC to 0 mph), which keeps the truck at a safe distance and provides a more confident driving experience. Detroit Assurance 5.0 also offers optional Active Lane Assist (ALA), which includes Lane Keep Assist, Auto Stop, Lane Departure Protection and Steer Assist. Steer Assist can help reduce fatigue on the road and makes maneuvering in yards far easier. Additionally, 57X debuts Active Side Guard Assist (ASGA), an industry-first technology designed to mitigate blind side issues during right-hand turns.

Standard Detroit Connect offers a comprehensive and innovative suite of connectivity systems that provide real-time, actionable insights into vehicle performance and empowers better decision-making, resulting in less downtime and a better bottom line for owners.

All new for Western Star trucks, a digital dash display features a configurable instrument cluster to provide an experience similar to today’s luxury cars. The larger screens display entertainment options such as Apple CarPlay and Android Auto (which can be accessed with a smartphone), as well as vehicle information from Detroit Assurance. Integrated steering wheel controls let drivers control most entertainment and information functions without taking their hands off the wheel.

Represents Western Star DNA

The new 57X fully embraces the brand’s distinctive styling and a heritage of rugged reliability. Drivers can relax knowing that they are riding on DTNA technology proven over millions of highway miles.  

Four cab options are available to suit any application, including Day Cab, 60-inch Mid Roof, 72-inch Mid Roof or 72-inch Stratosphere. All deliver maximum comfort with leather seating and, on sleeper models, an optional enhanced driver’s lounge with table and Murphy bed provide for better rest and downtime. An easy to operate, best-in-class HVAC system, improved insulation, and a larger windshield contribute to a more comfortable driver experience.  

An all-LED exterior lighting package gives the 57X a distinctive look on the road while also providing greater road illumination for safer driving and Dual-Stage Intelligent LED headlights with sensors quickly melt ice or clear condensation. Interior LED lighting offers better performance and longevity.

Numerous customization and bright finish options are available to tailor the truck to the owner or driver’s needs. 

Production is planned to begin in early Q1 2023 at DTNA’s Cleveland (N.C.) Truck Manufacturing Plant.
