Western Star introduces 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 the lineup.
“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 and small fleets looking for a truck that provides the safety, efficiency, durability and prestige that only Western Star can deliver.”
Performance
The 57X is 5.8% more fuel-efficient than its predecessor, the 5700XE. This vehicle gives owners a choice of Detroit engine models. The DD13 Gen 5, DD15 Gen 5 and DD16 engines all deliver on-highway performance and fuel economy.
The 57X is available with Detroit Powertrain components, including Detroit DT12 Direct or Overdrive AMT transmissions. Intelligent Powertrain Management anticipates terrain and adjusts to road conditions. Available Detroit front steer and high-speed ratio rear tandem axles contribute to fuel efficiency and performance while reducing maintenance.
The following new aerodynamic features on the cab and chassis help the 57X minimize fuel consumption:
- New aerodynamic hood and bumper with air ducts
- Roof and chassis fairings for the Day Cab, 60-in. and 72-in. 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-in. sleeper side extenders (12-in. for day cabs)
- Optimized drive wheel fairings smooth the air flow as it passes the trailer
- FlowBelow mold-in color drive wheel covers
Technology
The new 57X is equipped with safety and connectivity features designed to protect the driver, pedestrians and other motorists, while providing the operator with real-time information about the vehicle.
It comes standard with the 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 enables maneuvering. Additionally, 57X debuts Active Side Guard Assist (ASGA), a technology designed to mitigate blind side issues during right-hand turns.
Standard Detroit Connect offers a suite of connectivity systems that provide real-time insights into vehicle performance and facilitates decision making.
All new for Western Star trucks, a digital dash display features a configurable instrument cluster. The 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.
Operation
Four cab options are available to suit any application, including day cab, 60-in. mid roof, 72-in. mid roof or 72-in. Stratosphere. All deliver comfort with leather seating. On sleeper models, an optional driver’s lounge with table and Murphy bed is available.
An all-LED exterior lighting package gives the 57X a distinctive look while also providing road illumination for safer driving. Dual-Stage Intelligent LED headlights with sensors quickly melt ice or clear condensation. Interior LED lighting supports 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.
