Kenworth Introduces New Highway Model

Kenworth Truck Co.

LOUSIVILLE, Ky. — Kenworth Truck Co. introduced its new T700 tractor at the Mid-America Trucking Show here, one of three new trucks the manufacturer unveiled at the event.

The new truck will be available with Kenworth parent company Paccar Inc.’s new 12.9 liter MX-8 engine, which produces up to 485 horsepower and up to 1,650 lb-ft or torque.

The trucks will come equipped with Eaton’s UltraShift Plus transmission.

Kenworth chief engineer Preston Feight said the T700 has the lowest aerodynamic drag of any truck in the company’s history. The two T700 models on display here both wore decals announced the truck has earned SmartWay certification from the Environmental Protection Agency for its aerodynamics.

Feight called the truck’s unveiling “one of the most significant introductions in our history.”

Other features include a two-piece bumper and side fairings available in either molded or body color, and headlights borrowed from the T660 model.

Inside, the truck features eight-foot ceilings and a 42-inch liftable lower bunk.

Production is scheduled to begin this summer.

Kenworth also introduced two medium-duty models, the T440 and T470, for vocational and less-than-truckload applications.
