Peterbilt's Model 579 receives Smartway designation

Peterbilt Motors Company announced that its innovative new Model 579 received the U.S. Environmental Protection Agency's (EPA) SmartWay designation. The Model 579 joins Peterbilt's lineup of SmartWay designated vehicles, which includes the Model 587, Model 386 with and without LNG, and Model 384.

"After extensive product development and aerodynamic refinement, we are very proud to obtain the SmartWay designation for the Model 579," said Bill Kozek, Peterbilt General Manager and PACCAR Vice President. "The Model 579 SmartWay designated vehicle offers integrated aerodynamic features and fuel efficiency solutions for customers, further demonstrating Peterbilt's leadership in developing innovative quality products."

The Peterbilt Model 579 meets SmartWay's established comprehensive set of fuel-saving, low-emission equipment specifications for new Class 8 long-haul tractors and trailers. Class-8 tractors equipped with the required components and features are considered EPA-designated SmartWay Tractors.

"Fleets are continuously managing diesel price fluctuations, a stronger environmental focus and a desire to recruit and retain the best drivers," said Kozek. "And the 579 addresses these issues through innovative, advanced technologies, optimized powertrain packaging, including the PACCAR MX engine, and aerodynamic designs."

The Model 579 features:

  • Distinctive Aerodynamic New Styling – Performance and productivity drove the design process to create distinctive, new Peterbilt styling that is purposeful and efficient.
  • New Interiors Equal Productivity, Comfort – Two trim levels provide the optimal balance between comfort and driver performance.
  • Vehicle System Enhancements – An electrical system is designed on a robust architecture that includes innovative protection, routing design elements, and improved electric-over-air rocker switches. And, an optimal chassis system reduces overall vehicle noise, vibration and harness as well as provides a durable foundation for a long, reliable vehicle life that translates into exceptional resale value.
  • Optimized Powertrain Configurations – The Model 579 is available with the PACCAR MX engine and PACCAR by Eaton transmissions, and can be synchronized to achieve the highest fuel economy based on customer operational requirements.

"Achieving the EPA's SmartWay Designation is a validation of our extensive design of testing process," added Landon Sproull, Peterbilt Chief Engineer. "The continuous refinement of aerodynamic efficiency through hundreds of iterations of Computational Fluid Dynamics, wind tunnel testing, and customer feedback has resulted in best-in-class performance, and our engineering teams couldn't be more excited."
