Cummins X15 & PACCAR Endurant Powertrain
The proven 15.0L Cummins X15 producing 450 horsepower was designed for fleets and owner-operators who demand reliability, fuel efficiency, and the ability to handle heavy freight with confidence. Whether pulling through mountain grades or cruising across the interstate, the X15 delivers the power and durability that has made it one of the industry's most trusted heavy-duty engines.
The PACCAR Endurant 12-speed automated transmission automatically selects the ideal gear to keep the engine operating in its most efficient RPM range. This results in smoother shifting, improved fuel economy, reduced driver fatigue, and lower maintenance costs compared to traditional manual transmissions.
Efficient 3.08 Rear Axle Ratio
The 3.08 rear axle ratio was selected to maximize highway fuel economy while still providing excellent pulling performance for today's freight applications. Lower cruising RPMs reduce fuel consumption, engine wear, and cab noise, helping lower the overall cost per mile.
Kenworth AG400L Air Ride Suspension
The AG400L air ride suspension provides exceptional ride quality by absorbing road shock and vibration before it reaches the cab or trailer. This reduces driver fatigue on long trips while helping protect valuable freight, making it a preferred suspension for premium highway operations.
Proven Braking Performance
This truck is equipped with heavy-duty air drum brakes, providing dependable stopping power, long service life, and straightforward maintenance. Combined with the integrated engine brake, drivers benefit from improved downhill control, reduced service brake wear, and greater confidence when operating in mountainous terrain or heavy traffic.
Premium 76-Inch Raised Roof Sleeper
The spacious 76-inch raised roof sleeper was designed to keep drivers comfortable during extended trips. Equipped with double bunks, a refrigerator, built-in cabinets, and a workstation desk, it provides the amenities needed to improve productivity and make life on the road more comfortable while maintaining the aerodynamic efficiency of the T680 platform.
