The Kenworth T680 in day cab, 52-in. mid-roof sleeper and 76-in. sleeper configurations now can be specified with the factory-installed Cummins Westport ISX12 G natural gas engine rated up to 400 hp and 1,450 lb.-ft. of torque.
According to Kenworth, the ISX12 G requires a single fuel source and can run on either CNG (compressed natural gas) or LNG (liquefied natural gas). The engine uses a maintenance-free, three-way catalyst and does not require a diesel exhaust fluid (DEF) tank, diesel particulate filter (DPF) or selective catalytic reduction (SCR) technology. Kenworth works with such companies as Agility Fuel Systems, Trilogy Engineered Solutions, and McNeilus to provide natural gas tanks and fueling systems.
“The new, natural-gas powered Kenworth T680 especially appeals to truck fleets and operators interested in low cost of operation opportunities from the effective combination of the T680’s fuel-saving aerodynamics and cost-efficient natural gas fuel,” says Andy Douglas, Kenworth national sales manager for specialty markets.
Since entering production two years ago, the Kenworth T680 has become Kenworth’s most popular truck of choice for fleets interested in excellent fuel economy and outstanding driver comfort features, the company says. The T680 was introduced in day cab and 76-in. sleeper configurations, and the 52-in. mid-roof sleeper option was added last year.
