Western Star Introduces All-New 47X




Western Star recently introduced the all-new Western Star 47X. The truck complements the Western Star 49X to establish the Western Star X-Series and extend the platform’s reach into entirely new vocational applications.

With a standard 2,834 mm BBC, the 47X is well suited to regions or applications that require a shorter overall vehicle length and for those that need to meet local bridge law requirements, an optional 2,814 mm BBC. With the shorter hood and a wheel cut up to 50°, the 47X further optimizes maneuverability for work on construction sites or operation in congested urban environments.
Western Star has a long legacy of manufacturing durable, hard-working trucks. With the X-Series, DTNA engineers have evolved that legacy to consider the needs of today’s customers and have completely reimagined the modern vocational truck.

The 47X is approximately 90 kg lighter than the 49X in like-for-like spec and is best for weight-sensitive applications like mixers and bulk haul. All X-Series trucks have tougher, yet lighter, single-channel frame rail options versus legacy products. The platform offers frame rails with best-in-class RBM (resisting bending moment) to last longer and return greater payload. A new 9.5 mm single channel rail option is available and features comparable strength as today’s 11 mm rail. Standard high-strength aluminum forward, rear and end-of-frame crossmembers further reduce mass, as does a new 2-battery option.

The X-Series steel-reinforced aluminum cab further reduces mass by up to 8% while offering greater driver comfort with 13% more space than competitors. An optional 2-person bench seat is available for applications demanding a large on-site crew, and a new space-optimized, in-cab battery box affords additional legroom to the operator. An optional roof-mounted condenser offers maximum airflow through the radiator for stationary applications like construction and mining while keeping operators comfortable.

The 47X’s unique hood offers industry-leading forward visibility of 7.55 m – a 28 cm improvement over the 49X – while its composite construction and ISO Tech suspension system resists bending and cracking by absorbing and dissipating vibrations from road inputs.

The 47X comes standard with the Detroit DD13 Gen 5 engine, which features higher compression ratios and a new swirl piston design to further improve combustion and efficiency. ThermoCoasting in the DD13 Gen 5 prevents aftertreatment cool-down during a driving regen to keep the system at its optimum temperature and significantly reduce the need for parked regens.

For weight-sensitive applications, the Cummins L9 and X12 engines are available for the 47X. Optional front-engine power take-off (FEPTO) is offered on both Cummins engine offerings and the Detroit DD13 for applications like snowplows. Similarly, rectangular fuel tanks and a raised aftertreatment system mounting are offered with Cummins engines for better clearance for belly plows, making them a clear choice for municipalities and customers maintaining critical roadways in the winter months.

The 47X is also offered with the all-new DT12-V transmission, which includes 3 work-ready mode applications: Rock-free mode, Off-road mode, and Paver mode for the challenges of specific vocational applications.

Western Star partnered with leading truck equipment manufacturers (TEMs) to ensure the X-Series supports fast and efficient upfits. The 47X’s mid-chassis packaging has a number of clear back-of-cab configurations while unobstructed frame rails provide more efficient body integration. The QuickFit Interface System offers ready access to electrical architecture and was designed for easy TEM interface, programming and access to power. The CHEC Tool from DTNA enables TEMs and dealers to view and modify electrical configurations, giving them the power to customize inputs and outputs and change parameters within minutes.

A Flex Panel located in the dash B-panel of the truck gives TEMs the ability to mount body controllers, making Western Star the only OEM that does not require compromising space between the seats to do so. The Flex Panel can also accommodate additional gauges, switches, or a RAM Mount prep, depending on customer needs.
