The 2026 Western Star Lineup: Built for Every Mission
The Western Star X-Series family includes three distinct models designed for different applications:
- 47X – Optimized for weight-sensitive vocational jobs.
- 49X – The heavy-duty workhorse for demanding tasks.
- 57X – The long-haul flagship for premium on-highway performance.
Each model shares Western Star’s legendary toughness, advanced Detroit® powertrains, and cutting-edge safety systems to maximize uptime and productivity.
Western Star 47X: Compact, Capable, and Customizable
Purpose-built for vocational operations where maneuverability and upfit flexibility are essential, the 47X delivers exceptional performance without excess weight. Its shorter 110.8-inch BBC makes it ideal for municipal work, mixers, and bridge-law applications.
Power comes from options like the Detroit® DD13® Gen 5 (up to 525 hp / 1,850 lbs.-ft.) or Cummins L9 and X12 engines. The 47X supports manual, automatic, and Detroit® DT12-V automated transmissions for maximum spec flexibility.
Inside, the driver-focused cab provides excellent visibility, an ergonomic wraparound dash, and durable interior finishes designed to withstand years of jobsite abuse while maintaining operator comfort.
Western Star 49X: The Ultimate Workhorse
The 49X is engineered to dominate the most punishing environments—from logging operations to heavy-haul construction. Its reinforced frame and steel-reinforced aluminum cab deliver strength without unnecessary weight.
Engine choices include the Detroit® DD15® Gen 5 (up to 505 hp / 1,850 lbs.-ft.), the DD16® (up to 600 hp / 2,050 lbs.-ft.), or the Cummins X15 (up to 605 hp / 2,050 lbs.-ft.). Paired with Detroit’s vocational DT12-VX transmission and available TufTrac®, AirLiner®, or Hendrickson suspensions, the 49X can be configured for virtually any job.
The 49X also features the Detroit Assurance® Suite of Safety Systems, including Active Brake Assist 5, Side Guard Assist, and Adaptive Cruise Control to 0 MPH, bringing advanced safety technology to the vocational market.
Western Star 57X: Advanced, Aerodynamic, and Driver-Focused
For 2026, the 57X represents the most technologically advanced on-highway truck Western Star has ever built. It combines aerodynamic efficiency, luxurious comfort, and Detroit-integrated performance for long-haul excellence.
Engine options include the Detroit® DD13® Gen 5, DD15® Gen 5, and DD16®, each paired with the Detroit® DT12® Direct or Overdrive AMT for seamless shifting and optimized fuel economy.
The 57X’s interior is designed around the driver, featuring a digital dash, diamond-stitched leather seating, and an available 72-inch Stratosphere High Roof sleeper for maximum rest and productivity. Standard features like Detroit Connect® Virtual Technician, Active Brake Assist 5, and Adaptive Cruise Control make it both intelligent and safe for life on the open road.
