Kenworth introduced the new T660 regional hauler and its first 6×6 configuration for the T370 medium duty model yesterday at the Mid-America Trucking Show.
The T660 offers shorter wheelbases, tighter chassis packaging, enhanced maneuverability and weight savings, but maintains the same fuel tank capacity as a T660 with forward chassis fairings, according to Kenworth.
“This new Kenworth T660 option is especially useful for regional haulers interested in operating aerodynamic trucks to help increase fuel efficiency and reduce fuel costs,” said Preston Feight, Kenworth chief engineer. “The Kenworth T660 regional hauler configuration offers the same styling and lighting advantages – and similar aerodynamic advantages – as the standard T660 with the maneuverability and fuel capacity of the Kenworth T800.”
The new T660 configuration removes the standard under-cab chassis fairing and replaces it with a cab-mounted extension of the hood fender, allowing larger diameter 24.5-in. and 28.5-in. fuel tanks to fit under the cab. The use of a 24.5-in. diameter fuel tank can reduce the wheelbase by up to 19 in., while a 28.5-in. diameter fuel tank provides a potential wheelbase reduction of up to 34 in. The new configuration also reduces weight by at least 250 lbs. from a comparably equipped Kenworth T660 with forward fairings, the truck maker said.
The 6×6 configuration for the Kenworth T370 medium duty model is designed for applications that require a heavier front axle and tandem rear axle, including utility service, construction, oilfield service and boom trucks, in addition to municipal applications.
The truck features a factory-installed front drive axle available in ratings ranging from 10,000 lbs. to 16,000 lbs. The 6×6 will be equipped with a 40,000-lb. rated rear suspension. Initially, the Chalmers series 854-40 suspension will be offered, followed by the addition of the Hendrickson Primaax EX rear air suspension later this year. T370 6×6 customers can choose either the PACCAR PX-6 or PACCAR PX-8 engine, according to Kenworth.
The company also showed off its new line of seats exclusively for the Kenworth T700. The GT701, GT702 and GT703 seats offer a range of options and features, including an advanced air suspension system that can automatically adjust to the weight of the driver.
The seats come in vinyl, cloth or ultraleather, with coverings in gray, black and red, and with options for matching or contrasting stitching. The cushions can be removed and replaced without changing the seat’s suspension structure. All GT700 series seats offer optional heating, while the GT703 adds the option for cooling with premium leather covering. The GT703 also comes with an exclusive upper back adjustability feature that provides improved shoulder and neck support over a wide range of recline angles.
