What is it like to drive a giant and loaded 64,000 lbs dump truck on an off-road course, and into an active mine? I find out on this episode of TFLoffroad. Western Star invited me to their Diamler Trucks proving grounds in central Oregon for the world debut of the all-new 2021 Western Star 49X family of vocational heavy hauler trucks.
The 49X trucks are fully redesigned to be more capable, durable, and more safe. It took the team at Western Star six years to design, develop, test, and validate the new trucks. It all starts with a new and updated frame. The new architecture enables the trucks to be approximately 350 lbs lighter than before. In front, the frame design allows the engine and drivetrain to sit a little bit lower. This in turn allows a bit more visibility for the driver, looking over a sloped hood.
The red dump truck I am driving in this video is equipped with a DD16 turbo-diesel engine. It comes with up to 600 horsepower and 2,050 lb-ft of torque. The truck I’m driving here has a rating of 560 hp and 1,850 lb-ft. This engine has a displacement of 15.6 liters. The engine itself weighs about 2,837 lbs (dry weight). It also holds 45.5 quarts of oil. There are also several other engine options: DD15, DD13, Cummins X15, X13, and L9.
The hood and cab have also been redesigned. The hood has its own suspension system to withstand rough terrain without a lot of vibration. The cab offers easier egress with a large door opening and a newly designed step/stair system. The LED headlights are new as well. It’s easy to recognize the new 49X with its new style.
Take a look at the video below for all of the off-road big truck fun.
