Kenworth Truck Co. announced that its T680 on-highway flagship Class 8 is now available for order for the first time with the combination of the Paccar MX-11 engine and the new Paccar automated transmission.
The vehicle is designed for linehaul and regional haul applications up to 110,000 pounds gross vehicle weight, according to the Kirkland, Wash.-based company, which is a unit of Paccar Inc.
The MX-11 engine offers up to 430 hp and 1,650 lb.-ft. of torque, and is 400 pounds lighter than 13-liter engines. The automated transmission is up to 105 pounds lighter compared with comparable transmissions, and has a 750,000-mile oil change interval.
The transmission is paired with Kenworth’s new column-mounted shifter, putting gear selection and engine brake controls at the driver’s fingertips.
The powertrain package also includes a 40,000-pound tandem rear axle.
