The newest addition to Peterbilt’s vehicle lineup–the vocational Model 567–is now in full production. The truck or tractor can be configured to meet a wide range of heavy- and severe-duty applications as a day cab or with the OEM’s complete line of detachable sleepers. Unveiled earlier this year, the new model was developed during an extensive research and testing program at the PACCAR Technical Center in Mount Vernon, Wash.
Peterbilt’s Model 567 can be ordered in 121- and 115-in. BBC versions with a wide variety of components and axle configurations. The model is standard with the PACCAR MX-13 engine rated up to 500 HP and 1,850 lb./ft. of torque.
A main feature of Peterbilt Model 567 is its lightweight all-aluminum cab with steel reinforcements. “For additional strength and cab stability, steel upper A-pillars and rear corner reinforcements have been added,” explained Landon Sproull, Peterbilt chief engineer. “The cast aluminum front cab mounts distribute road stresses evenly, reducing road-induced wear and improving ride quality.”
Durability is further improved with the Model 567’s Metton hood, Sproull noted, which is highly resilient and can absorb impacts that would shatter or crack other materials. Additionally, the Model 567’s chassis is 10 to 15% stiffer than comparable products, he added, while its clean frame rails facilitate ease of installation for bodies, auxiliary axles and hydraulic tanks.
Sproul also pointed out the panoramic windshield on the Model 567 that features integrated locaters in the 2.1 meter-wide cab structure to allow for field repairs, as well as A-pillars with strategically placed supports for added strength, allowing them to be 13% narrower than other designs. The forward lighting system on the Model 567 features projector module low beams, which have a 2,000-hour lifecycle and complex reflector high beams.
According to Sproull, Peterbilt engineers used a driver-centric research and planning process to develop the Model 567. Included were interviews of hundreds of drivers about their preferences for a productive and comfortable operating environment.
“Assembly is in full swing for the Model 567 with strong demand for the new model in different markets, including dump, mixer, heavy haul and refuse applications,” said Robert Woodall, Peterbilt director of sales and marketing.
