Peterbilt Motors Company has announced the launch of its new on-highway Model 579. According to the company, the thoroughly redesigned model delivers improvements in aerodynamics, efficiency, comfort, technology and uptime.

Peterbilt worked with over 50 of its customers to understand their unique operations and needs, incorporating their input into the design of the new 579. Validation units accumulated 1.5 million real world miles and combined with the durability testing done at the Paccar Technical Center, the new model is the most reliable truck ever designed by the company.

Developed over a five-year span, over 1,000 hours of computational fluid dynamics (CFD) analysis and 7.8 million CPU processing hours were spent evaluating the exterior design of the new 579. The research resulted in an enhanced aerodynamic profile and a 7% improvement in fuel economy.

Key exterior features to the new truck include a redesigned stronger Metton hood that is narrower and more resistant to damage. A new 3-piece bumper integrates the forward radar cover for collision mitigation, with a larger aerodynamic air dam, and provides both protection against damage and lower replacement costs

Highlighting the New 579 is a 15” Digital Dash Display, delivering all the information drivers need in a clean, intuitive interface. In addition, the new 579 features Advanced Driver Assistance Systems providing drivers the latest safety technologies in the form of collision mitigation, lane departure warning and the new lane keeping assist (LKA), among others. Prior to trip departure the Digital Display has the ability to run through a visual Systems Check, inspecting 13 systems and providing a green checkmark with each passed test. Post-trip, a detailed Trip Information screen provides a breakdown of important metrics of the most recent journey.

The interior features soft-touch materials with a fit and finish that delivers an outstanding driver experience. The 579 UltraLoft with an integral sleeper provides 70 cubic feet of space, offering more storage than any comparable integral sleeper. Drivers will feel right at home with plenty of headroom from the eight-foot high ceiling. The cabin has room for small appliances, including a 1.1 cu ft microwave, a 32” TV, a tall wardrobe closet, multiple power outlets and optional bunkbeds with a clever fold-away ladder. Multiple windows provide plenty of natural light and additional ventilation. At night, interior lighting from dome LED lights and three directional spot/reading lights provide added convenience and safety. Small additions like a fixed cup holder and the option for multiple USB charging ports in the center console make life on the road more comfortable.

“The Class Leading Technologies found in the new Model 579 are game-changing. The clear and precise information relayed to drivers through the Peterbilt Digital Display, combined with the advanced safety systems found throughout the truck, provide a much higher level of awareness of the truck and its surroundings.” said Jason Skoog, Peterbilt general manager and PACCAR vice president.

The new Model 579 is available for order in a day cab configuration, integral 80” UltraLoft sleeper and a variety of other sleeper sizes.
