The instrumentation systems' multiplexed design enhances reliability and greatly simplifies the wiring behind the dash. LED back lighting in the face plate and pointers makes it easier to read gauges and see warning lights.
Power door locks are now standard, with electric window lifts standard on the passenger side and optional on the driver side. Window, door lock and mirror controls are located on the door for easy access.
Two cab trim levels are available: the classic Kenworth Diamond and machine stitched with French seams. Both are available in four primary/trim color combinations.
Curved windshields are now available for the sloped hood W900, high and wide hood T800 and C500 vocational trucks. A flat windshield also remains available.
The popular Kenworth T800 short-hood model is now offered with FEPTO. This configuration is available with Caterpillar C11 and C13 engines up to 380 hp, and the Cummins ISL engine up to 350 hp.
Some unique features differentiate the T800 short hood FEPTO model from the standard version. Extended frame rails are available with a 66-in. bumper setting in dimensions of 11 5/8" x 3/8", 10 3/4" x 3/8" and 10 11/16" x 1/2".
The 950-sq.-in. radiator includes a modified bottom tank for PTO shaft clearance, and the radiator-mounted grille allows the hood to be tilted for daily underhood inspections without contacting frame-mounted equipment.
Earlier this year, Mack expanded its Granite line with the addition of the Granite Axle Back for customers seeking an axle back configuration in a modern, lightweight chassis.
The backbone of this truck is the company's vocational Cornerstone chassis, which uses 300mm tall rails. The rails are offered in 8-, 9.5- and 11.1mm thicknesses with a 90mm flange, as well as 11.1mm with a 105mm flange. Rails are tempered to a minimum 12,000-psi yield strength.
The standard UniMax steer axles feature sealed, unitized hubs specifically for vocational work. Rated from 12,000 to 23,000 lbs., these sealed axles are virtually maintenance free.
Location of the front axle is key on an axle back truck. The Granite Axle Back is a full 17 in. farther back than an axle forward. It measures 51.5 in. from the back of the cab to the center of the front axle. This allows the body manufacturer to transfer maximum payload to the front axle.
While many components are shared among the Granite family, there are a few unique features. The headlight is designed for vocational use with a Lexan covering that is more durable than sealed beam headlamps. Flexible fender extensions are positioned over the wheels to protect the hood and control splashing.
Peterbilt has unveiled electrical system improvements, new interiors and HVAC improvements for it 2006 model line, which includes the 379, 385, 378 and 357.
Gauge and instrumentation reliability has been significantly improved with the introduction of multiplexed wiring, which reduces the amount of behind-dash wiring for improved diagnostics and serviceability. An Electronic Service Analyst (ESA) tool allows service technicians to accurately monitor, troubleshoot and repair the electrical system by isolating sensors and gauges.
There are three new interior trim levels: ProBilt, Prestige and Platinum. The ProBilt is a base level interior specifically designed to meet the needs of vocational applications. It utilizes robust, easy-to-clean materials, and is available in Arctic Gray coloring. The Platinum level is the premium interior, while the Prestige level incorporates many Platinum level refinements and features. Both are available in four color options: Artic Gray, Burgundy Wine, Maritime Blue and Saharan Tan.
Side-View visibility has been increased by a re-styled passenger side door. The area where the top of the door meets the bottom of the window was lowered and angled approximately 2 in. in the front and 1 in. in the rear.
The HVAC system was completely redesigned using Computational Fluid Dynamics to boost performance and improve climate control.
In addition, the Caterpillar C9 engine is now an available option for the vocational Model 357. This can help take about 780 lbs. out of the chassis vs. a C11 for weight-sensitive applications.
