Western Star X-Series expands with new weight-conscious vocational model

47X offers shorter vehicle length and optimized maneuverability for tight spaces

The Western Star 47X is lighter and more agile for a variety of vocational tasks.

Following in the steps of the fully updated 49X vocational truck released in 2020, Western Star is adding a new model targeted at jobs that require a shorter vehicle length and enhanced maneuverability.

The 47X is suited to a range of applications, such as mixers and dump trucks, while offering shorter BBCs and tighter turning for work on urban construction sites where space is at a premium. It's designed to be a complementary truck to the 49X, which is designed for heavy haul, logging and similar roles.

"One of the things we worked on really hard for the 47X is taking weight out. When you think of the X-Series product line, the 49X is bigger has a larger displacement engine, larger GCW, larger cooling package and more air filtration; the 47X is a lighter, more nimble chassis that we expect to sell more in a lot of construction spaces," explained Samantha Parlier, vice president of vocational market development with Daimler Trucks North America.

Smaller and lighter but still powerful

The 47X offers a 111.6-inch BBC along with an optional 110.8-inch version, and its lower weight compared to the 49X is a feature that will appeal to weight-conscious operations like concrete delivery. Approximately 200 pounds lighter with similar specs, the 47X benefits from weight-reducing features like a steel-reinforced aluminum cab that cuts weight by up to 8 percent. Single-channel frame rails, high-strength aluminum crossmembers and other updates have helped slim down the new truck's overall weight and allow higher payloads.

Design efforts have been focused on ensuring a clean back of cab for truck equipment manufacturers to take advantage of. A number of different configurations are available, and frame rails are designed to be unobstructed for easier integration. Western Star also offers the QuickFit Interface System for easy access to electrical architecture, and Daimler Trucks North America's CHEC tool lets TEMs and dealers check electrical configurations with ease.

The 47X flex panel in the dash can be easily fitted with controls for body functions.

Cab redesign gives good look ahead

At the front of the truck, the 47X continues in the vein of its larger cousin with a unique redesigned hood. The composite construction hood fitted with ISO Tech suspension system is designed to resist bending and cracking, while also providing excellent forward visibility of 24.8 feet, slightly better than the 49X.

The cab itself is larger and takes a cue from the 49X with its high trenched roof.

"You can get that cab guard down nice and low; it also allows a larger door opening, so you can get in and out with a hard hat, feeling like you have a lot of space without forcing your cab guard to go up," Parlier noted.

Inside, legroom is expanded and operators will find a wrap-around dash with easy access to the driver command centre and a flex panel allowing TEMs to mount controllers without compromising space with a control box between the seats.

"We are the only OEM that offers a flex style allowing the truck equipment manufacturers to fully build their controls on the dash," Parlier noted. "There's no control box installed by the TEM on this truck - all of the controls are located on the dash."

That placement adds safety as well, as the driver does not have to look down between the seats for body controls while maneuvering on busy job sites.

A selection of work modes can be selected to ensure the 47X runs efficiently on the job.

Engine options add flexibility

The 47X is equipped standard with the Detroit DD13 Gen 5 engine, which offers higher compression ratios and a new swirl piston design to improve combustion and efficiency. The engine also features ThermoCoasting, preventing aftertreatment cooldown during a driving regen and keeping the system at optimum temperatures.

Cummins L9 and X12 engines are also available for weight-sensitive applications. A front-engine power take-off is available on both Cummins engines and the DD13, allowing for use in applications like snow plowing.

The DT12-V transmission is offered on the 47X, offering three work-ready mode applications: rock-free mode, off-road mode and paver mode, matching key vocational uses.

Detroit Assurance is standard on any 47X fitted with the DD13. The active safety system suite offers active brake assist, side guard assist, adaptive cruise control and other features to improve safety for drivers and those around the truck.

The 47X is available to order now, with customer delivery starting in early 2022.
