The new Model 579 from Peterbilt Motors Co. has received the U.S. Environmental Protection Agency’s (EPA) SmartWay designation. The Model 579 meets SmartWay’s fuel-saving, low-emission equipment specifications for new Class 8 long haul tractors, the truck maker reported.
“Achieving the EPA’s SmartWay Designation is a validation of our extensive design and testing process,” said Landon Sproull, Peterbilt chief engineer. “Included is the continuous refinement of aerodynamic efficiency through hundreds of iterations of Computational Fluid Dynamics, wind tunnel testing and customer feedback.”
Features of the new Peterbilt Model 579 include aerodynamic styling; an electrical system architecture that includes protection, routing design elements, and improved electric-over-air rocker switches; and a chassis that reduces noise and vibration, Sproull noted. The Model 579 is available with the PACCAR MX engine and a PACCAR by Eaton transmission.
“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. “Fleets are continuously managing diesel price fluctuations, a stronger environmental focus and a desire to recruit and retain the best drivers. The 579 addresses these issues with innovative, advanced technologies.”
The Model 579 joins Peterbilt’s lineup of SmartWay designated vehicles, which includes Model 587, Model 386 with and without LNG, and Model 384.
