KENWORTH has a variety of new offerings, including PACCAR engines, the T440, a new hybrid design, and a FEPTO lineup featuring the T470, T800, and C500.

The new 2010 PACCAR MX engine is available on Kenworth Class 8 trucks, with a wide horsepower range of 380 to 485 hp and torque outputs up to 1750 ft-lbs.

Kenworth also has several 2010 Cummins engines in its lineup. The Cummins ISX15 engine, rated from 400 to 600 hp and 1450 to 2050 ft-lbs of torque, is offered for the T660, T700, T800, W900, and C500. The Cummins ISL9 engine, rated up to 380 hp and 1300 ft-lbs of torque, is available for the Kenworth T440, T470, and W900S. The Cummins ISX11.9 became available in the second half of this year in the T660, T800, and W900S models.

The new Kenworth T440 tractor, which made its public debut at the Mid-America Trucking Show, is suited for fleets and truck operators in regional haul and pickup and delivery applications.

“It will really fill the void created when GM and Sterling stepped away from the mid-size, mid-class range, and it's an opportunity for us,” said medium-duty marketing manager Doug Powell. “It's used in a multitude of applications. The whole point was to bring out a line that has versatility.”

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. The new tractor is standard in a day cab configuration. Options include the Kenworth Extended Day Cab, which has an additional six inches of length and five inches of cab height compared to the day cab and the 38" Kenworth AeroCab sleeper.

The 2010 PACCAR PX-8 engine is standard with ratings to 350 hp and 1000 ft-lb of torque, and the optional 9-liter, 2010 Cummins ISL engine is rated to 380 hp and 1300 ft-lb of torque. The T440 offers 6-, 9-, 10-, 11-, and 13-speed manual and 5- and 6-speed automatic transmissions; and 12,000- to 22,000-lb rated front axles, 21,000 to 30,000-lb rated single rear axles, and 40,000- to 46,000-lb rated tandem rear axles.

Kenworth has enhanced its componentry packaging for its T270 Class 6 and T370 Class 7 diesel-electric hybrid models and also added a new inverter design for 2010.

Kenworth has placed all its hybrid components, including the starter batteries, chassis load center, cooling package and new inverter, into one battery box located underneath back of cab on the driver side. The Eaton diesel-electric hybrid power system is located on the left frame rail, forward of the rear axle. Kenworth also offers 9' long high power cables, which allow body builders to relocate the power system to maximize frame rail space. These locations help provide easy access and the best set of options for customer frame requirements.

The new inverter offers improved cable clearance which is especially useful for utility customers, enhanced power distribution center with easy access to fuses that are now closer to the power source, and improved access and cable pass through. Kenworth offers a body builder power distribution module as an option. This module provides dedicated body builder battery power and ground in a convenient, easily accessible package mounted to the aft side of the battery box.

Kenworth hybrid tractors, available up to 55,000-lb GCW, are for local-haul applications, including beverage, general freight, and grocery distribution. Kenworth hybrid trucks are for pickup and delivery, utility, and service applications. Kenworth's goal is to enhance fuel economy by up to 30% in both pickup and delivery and hybrid tractor applications and up to 50% in utility operations.

The Kenworth hybrids use an integral transmission-mounted motor/generator; frame-mounted 340-volt, lithium-ion battery pack; and dedicated power-management system. Electricity generated through regenerative braking is stored and used for acceleration, assisting the diesel engine. Kenworth offers a high-resolution, full-color in-dash display to monitor the hybrid system. As the power requirements for different driving conditions change, the screen constantly updates the driver on system status, allowing the driver to optimize the performance of the hybrid system.

The FEPTO lineup

The T470 has a GVW ranging from a heavy Class 7 vehicle at 33,000 lbs up to a light Class 8 truck at 68,000 lbs. The vehicle offers full parent rail extensions, delivering maximum resistance to bending moment (RBM) from one end of the rail to the other. Front axles are rated from 12,000 to 22,000 lbs, single rear axles from 21,000 to 26,000 lbs, and tandem rear axles from 40,000 to 46,000 lbs. A full range of manual and automatic transmissions are offered.

The T800 is versatile, used from line-haul tractors with the 86" Studio AeroCab sleeper to severe service off-highway dump trucks to a simple daycab for local pickup and delivery.

It has three radiator sizes to match cooling performance to needs (1180, 1440, and 1780 sq in); engine sizes from 9-liter to 15-liter; accommodates up to 600 hp engines; is available in 115.5", 122.5", 125", and 133.4"; BBC dimensions; and has front axles from 12,000- to 22,000-lb ratings, and rear axles from 21,000-lb single to 105,000-lb tridems.

The C500 vocational model has received a new, larger cooling module and hood facelift for 2010.

The C500, which is designed to handle heavy loads over rough terrain, is ideal for demanding applications, including heavy haul, oilfield services, coal mining and construction. The increased size of the cooling module enhances the C500's ability to cool in harsh environments, ranging from desert sands to high-altitude stationary applications

The new 2010 C500 hood, which is available either in fiberglass or extremely durable sheet metal, accommodates the new 1,780-sq-in cooling module. This improved cooling capacity allows Kenworth to offer the C500 across-the-board for gross combination weights up to 200,000 lbs. The increase also allows stationary pumping with the maximum horsepower and torque available, which is 600 hp and 2050 ft-lbs, respectively.

Kenworth offers a variety of DEF tank options, which include small, medium, aerodynamic, and large round frame-mounted tanks for Kenworth's Class 8 trucks. Useable DEF capacities are 9, 18, 20, and 27 gallons. The large DEF tank provides customers with a range of over 5000 miles between refillings.

The 5.6-gallon tank provides clear back of cab. When combined with Kenworth SCR and diesel particulate filter (DPF), which are both packaged under the cab access step, there is essentially no impact to the body builder.

In addition to the DPF and SCR located under the passenger step, Kenworth also offers horizontal and vertical independent exhaust configurations for 2010.
