New Kenworth medium-duty models begin production at PACCAR assembly plant
The new-medium duty conventionals feature the Kenworth T180 (Class 5), T280 (Class 6), T380 (Class 7) and T480 (light Class 8). The new T380V and T480V models are for vocational applications. The Kenworth vehicles are available with the 6.9-litre PACCAR PX-7 and 8.9-litre PACCAR PX-9 engines. Kenworth also offers the near-zero emission Cummins Westport 8.9-litre L9N natural gas engine as an option.
The new PACCAR TX-8 automatic 8-speed transmission is standard. The transmission can handle up to 1,000 lb.-ft. of torque with 57,000-lb. GCWR when matched to the PACCAR PX-7 or PACCAR PX-9 engine.
The new trucks offer three hood types to support the lineup's application versatility - short aero hood (107.5-inch BBC) that accommodates front axles from 8K to 20K lbs., medium aero hood (109.5-inch BBC) for higher horsepower and AWD applications, and Kenworth's vocational sloped hood for the T380V and T480V, which employ a fixed grille for front engine PTO operations. The shorter wheelbases produce a tighter turning radius and enhanced maneuverability for urban or vocational operating environments.
The trucks may be specified with either a standard low roof or a raised roof option. The low roof is 63 inches tall, 4 inches shorter than the raised roof, making it ideal for height-restricted applications.
