47X — WESTERN STAR X-SERIES VOCATIONAL TRUCK Expanding the already impressive line of next gen vocational trucks.SIMPLY THE BEST TRUCKS WE’VE EVER BUILTWESTERN STAR TRUCKS have always been built to deliver more. More durability, more dependability and more value. And with the all-new X-Series family of vocational trucks, we’ve taken that commitment even farther. These are trucks that break new ground both on the jobsite and in how the job gets done. They break new ground in safety, in strength, in technology, in reliability and in what it means to build the world’s toughest trucks. They are trucks born from hard work, with a heritage of performing in a world of unforgiving conditions, just like the people who own them. That’s why we believe you don’t just buy a Western Star, you earn it. So, whether you’ve owned Western Star for years or never have before, it’s time to break new ground with both the all-new 47X and the all-new 49X.FEATURESCHASSISENGINEERED FOR LONG LIFE AND QUICK UPFITThe heavy-duty vocational frame underneath the 47X is engineered to stand up to the demands dump trucks, concrete mixers and crane trucks experience.CABA NEW CAB THAT’S JUST AS TOUGH AS OUR EXPECTATIONSConstructed from a premium-grade aluminum and enhanced with steel reinforcements.POWERTRAINPOWERTRAINS YOU CAN COUNT ON.

Detroit Connect translates the performance data of any type of truck into real-time information you can use to make the decisions that can help you keep those trucks working and earning.INTRODUCING DETROIT ASSURANCETechnology gets tough in the X-Series, the first Western Star trucks to feature the most advanced suite of active safety systems ever offered to the vocational market — Detroit Assurance. Detroit Assurance not only helps keep people safe, it helps you reduce the repair and operational costs of having a truck out of service by avoiding collisions — which can mean game-changing productivity to you.ACTIVE BRAKE ASSIST 5Active Brake Assist 5 detects distance and speed to moving and stationary objects in its path and determines if warning or braking is necessary. It's the only system on the market that works down to 5 MPH*, making it ideal for travel in congested urban areas. It also recognizes pedestrians who are about to cross in the truck's path, alerting the operator while partially braking, followed by full braking if the operator does not react.* with DT12 TransmissionSIDE GUARD ASSISTA game changer for safety in and around busy jobsites, Side Guard Assist detects objects on the passenger side of the truck and alerts the operator.ADAPTIVE CRUISE CONTROL TO 0 MPH AND TAILGATE WARNINGDetroit Assurance technology enables state-of-the-art features such as Adaptive Cruise Control to 0 MPH* and Tailgate Warning to ease driving in stop and go traffic, as well as help reduce collisions as operators travel from one jobsite to the next.* with DT12 TransmissionBRAKE HOLD MODEBrake Hold Mode enhances driver safety and comfort on the road and at the jobsite.
