The new 2023 Western Star 57X semi truck is finally here. It features the latest efficiency improvement and driver-assistance technologies that make it easy to drive. In this video, Kase jumps behind the wheel of this new big rig at a proving grounds closed-course highway to see what it’s like to drive a truck and trailer with a combined weight of 78,000 lbs. Is it simply a Freightliner Cascadia with a different front end? Here is what happens.
The front of the 57X is new with the latest design and headlights with optional two-stage heating elements. This will help melt snow and ice from the lights or remove condensation for better visibility. The latest chassis allows for the engine and transmission to sit a little lower for a better center of gravity. It allows for a lower hood line that in turn improves aerodynamics and forward visibility.
Under the hood is a selection of proven Detroit Diesel DD13, DD15, or DD16 turbo-diesel engines that offer up to 600 horsepower and 2,050 lb-ft of torque. The DT12 automated manual transmission is sending the power to the axles.
Join Kase in the video below for the entire driving experience of the newest long-haul big rig.
