Peterbilt’s 579 Gets EPA Smartway Designation

The Peterbilt 579 truck received EPA’s SmartWay designation.

DENTON, TX — Peterbilt Motors Company received the U.S. Environmental Protection Agency’s (EPA) SmartWay designation for its new Model 579. The SmartWay designation means the 579 meets EPA’s low-emissions and fuel efficient specifications for Class 8 vehicles.

“Achieving the EPA’s SmartWay designation is a validation of our extensive design of testing process,” said Landon Sproull, Peterbilt’s chief engineer.

Specifically, Sproull pointed to Peterbilt’s focus on refining aerodynamics via hundreds of computer programs, wind tunnel testing, and collecting feedback from customers.

Bill Kozec, Peterbilt’s general manager, echoed Sproull on the hard work it took to develop the 579, adding that the Peterbilt team is quite proud of obtaining the SmartWay designation.

“Fleets are continuously managing diesel price fluctuations, a stronger environmental focus and a desire to recruit and retain the best drivers,” Kozek said. “And the 579 addresses these issues.”

Peterbilt’s Model 587, 384, and 386 both with and without LNG, are also SmartWay designed vehicles.

The 579 is available with the PACCAR MX engine and PACCAR Eaton transmissions.
