Forged from the most extensive, rigorous product development process in the company’s history, Peterbilt Motors Company, last week, unveiled its all-new Model 579.
Featuring all-new innovations - from head-turning styling that is optimized for superior fuel efficiency to an interior that down to its last detail facilitates operator comfort and productivity, “the 579 exceeds the needs of fleet managers and drivers alike,” said Bill Kozek, Peterbilt general manager and Paccar vice president.
“The all-new 579 goes beyond meeting a market demand for an exceptional vehicle that satisfies both the bottom-line and operator expectations,” he added. “The 579 integrates legendary Peterbilt quality and innovation with a product platform that delivers in every aspect of vehicle performance, productivity and safety.
“From optimized cab dimensions to an enhanced chassis design, and from driver amenities to a revamped electrical system - every design element of the 579 was analyzed and engineered to provide real-world benefits and business solutions that exceed industry trends.”
While the look is unmistakably Peterbilt, the 579 features distinctive new styling that goes far deeper than just exterior beauty. According to Landon Sproull, the company’s chief engineer, performance and productivity drove the design process.
“Maximizing fuel economy was a priority and we achieved best-in-class aerodynamic efficiency through Computational Fluid Dynamics and subsequent wind tunnel testing,” he said.
“The 579’s interior design process was no less exacting than the aerodynamic exterior, and the results are a lineup of trim packages and driver amenities that are unmatched in the industry.”
The cab structure is a new design that features greater strength and enhanced safety. The 2.1 meter-wide, aluminum cab is strong, solid and lightweight.
Aerodynamic performance is enhanced through modular aero packages that meet the U.S. EPA’s SmartWay designation.
Sproull said the aero packages are designed to meet customer optimized requirements, with variable length chassis fairings, sleeper extenders and rubber flares, under-cab close-outs and under-fairing skirts.
The aerodynamic bumper is a three-piece design so individual sections can be replaced if they are damaged, improving serviceability and reducing costs.
The bumper is available with a molded-in-color finish that eliminates cosmetic issues if it is scratched or damaged and a painted finish that is durable and can be matched to any color.
The aero hood also has a three-piece design that is lightweight, durable and easy to service. It features the company’s most efficient tilt assist system that reduces lift effort to 25 pounds. Incorporated into the hood pivot system are supports that direct energy around the cooling module in the event of certain types of accidents - such as impact with an animal - that minimizes damage and helps allow the operator to drive the truck to a safe location for repairs.
“These improvements enhanced the signature Peterbilt styling elements such as the new chevron-style crown and grille with an oval-mesh pattern,” Sproull said.
“The Model 579’s interior design process was no less exacting than the aerodynamic exterior,” Sproull said, “and the results are a lineup of trim packages and driver amenities that are unmatched in the industry.”
“Hundreds of drivers were consulted during our research and planning to ensure the new cab and sleeper designs met the range of needs for spaciousness, comfort, productivity and efficiency. “The operating environment is designed around the driver and when it is time to rest and relax, the sleeper area is loaded with practical luxuries including ample storage and an integrated entertainment center that can accommodate a 22-inch flat panel television.”
