CHILLICOTHE, Ohio – Kenworth is gearing up for 2007 with the launch of several new products and enhancements, chief among them the new fuel efficient T660 highway tractor.
The first T660 chassis rolled off the assembly line at Kenworth’s Chillicothe, Ohio plant on Aug. 16. The truck was paired with a 2007 Cat C15 powerplant. All Kenworth chassis equipped with 2007 engines will be 2008 model year trucks, the company announced at a recent plant tour.
“As customers make their buy decisions for 2007 and diesel prices remain high, the new Kenworth T660 provides the latest fuel-economy solution while offering a reliable, quality product with low operating cost, advanced technology, outstanding driver comfort and high resale value,” said Bob Christensen, Kenworth general manager and PACCAR vice-president.
The truck is available with Kenworth’s 86-inch AeroCab and 72-inch AeroCab Aerodyne sleepers.
It features a forward-lighting system with new halogen projector low beams and an optional high intensity discharge configuration which the company said deliver 40% and 70% more light down the road than sealed beam lamps.
An enhanced multiplexed electrical instrumentation system is standard and Kenworth’s GPS navigation system is an option (or standard with the Kenworth Diamond cab interior).
The revamped driver’s display provides real-time fuel economy information, an ignition timer, on-board diagnostics and a gear display.
A T660 Pendleton Limited Edition is also available for 2007 delivery.
“Fleet drivers and owner/operators work hard and deserve to have a comfortable environment in their truck,” said Gary Moore, Kenworth assistant general manager for marketing and sales. “Kenworth and Pendleton Woolen Mills, both known for their outstanding quality products, have combined to offer the ultimate in interior comfort and styling for owner/operators and as a reward for top fleet drivers.”
The luxurious interior features: brown leather in the seats and door pads; a leather sofa bed with microfiber suede inserts; wood grain cab interior trim; and wool fabric accents.
Ready for ’07
Kenworth officials said the company’s entire line of trucks are ready for the 2007 engines.
“Kenworth has prepared its product line during the past several years for the upcoming engine emissions requirements,” said chief engineer, Mike Dozier. “Kenworth’s field test program has consisted of numerous vehicles operating in customer applications and from the PACCAR, Cummins and Caterpillar Technical Centers…This program has provided millions of miles of performance data to help support the development of overall system reliability. All aspects of Kenworth’s 2007 engine emissions program have been very closely coordinated with our engine partners, Cummins and Caterpillar.”
Kenworth’s 2008 tractors feature enhanced cooling systems to handle the extra heat generated by increased levels of exhaust gas recirculation.
“Kenworth used advanced design and simulation tools, advanced airflow solutions and the latest manufacturing technology to achieve increased cooling performance,” said Dozier. “Kenworth customers should not expect to see dramatic changes in styling or hood shape in current models resulting from the emissions changes.”
Trucks with 2007 engines will come standard with silicone coolant hoses and extended life coolant. Engine options on Class 8 tractors will include the Cummins ISX, ISM and ISL as well as the Cat C15 and C13. Kenworth will also begin offering the Cat C9 for vocational applications, the company has announced.
PACCAR medium-duty power
On the medium-duty end of things, Kenworth is offering the new PACCAR PX-6 and PX-8 powerplants on Class 6 and 7 vehicles.
The PACCAR PX-6 is a 6.7-litre engine available in Class 6 and 7 configurations. It will be available in ratings from 200-325 hp and 520-750 lb.-ft. of torque.
“The PACCAR PX-6 is the ‘efficiency’ engine with its high power density and the highest power to weight ratio in the industry,” Dozier said.
Its bigger brother, the 8.3-litre PX-8 will have horsepower ratings ranging from 240-330 hp and torque offerings of 660-1,000 lb.-ft.
A 360 hp PX-8 will be available for emergency vehicles. The PX-8 will be available in the Class 7 configuration and the tandem axle Kenworth T300, the company announced.
“The PACCAR PX-8 is the ‘power and torque’ engine,” explained Dozier. “Many medium-duty customers have expressed their desire for more power. The 1,000 lb.-ft. of torque translates to improved throttle response and acceleration.”
