Production of Peterbilt 579 kicks off

Production has begun on Peterbilt Motors Co.’s new flagship Model 579. Launched at the Mid-America Trucking Show (MATS) in March, the 579 features a 2.1-meter aluminum cab with optional detachable sleeper.

“This is truly a historic occasion for our Peterbilt Denton production team,” said Bill Kozek, Peterbilt general manager and Paccar vice president.

The Model 579 is standard with a Paccar MX 12.9L engine. Landon Sproull, Peterbilt chief engineer, reviewed some of the highlights of the new model at MATS, noting that 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.

According to Sproull, aerodynamic performance is enhanced through modular aero packages that meet the EPA’s SmartWay designation. 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.

“After years of research, product development, capital investments, customer input, and vehicle testing, this final result is a combination of total performance innovation and highest quality,” said Kozek. “This vehicle is truly one that delivers confidence and efficiency for bottom-line driven companies.”
