The T440 becomes the latest Kenworth model able to operate on both compressed natural gas (CNG) and liquefied natural gas (LNG), joining Kenworth’s W900S which began offering those options late last year. Both models are equipped with the ISL G engine and Allison transmissions.

Rated at 320 hp (239 kW) and 1,000 lb-ft (1,356 N·m) of torque, the ISL G is 2010-compliant without the use of selective catalytic reduction (SCR) or a diesel particulate filter (DPF). CNG and LNG fuel tanks can be configured to suit customer applications and range requirements. Kenworth also offers the T800 LNG truck equipped with the Westport GX engine.

The T440 has a gross vehicle weight (GVW) ranging from a heavy Class 7 vehicle at 33,000 lbs. up to a light Class 8 truck at 68,000 lbs. and is available with 12,000- to 22,000-lb. rated front axles, 21,000- to 26,000-lb. rated single rear axles, and 40,000- to 46,000-lb. rated tandem rear axles. Other key features include an aerodynamic sloped hood and 3-piece bumper; forward lighting with Halogen projector headlamps; high-quality multiplexed dash, and Kenworth Driver Information Center.
