Peterbilt on Wednesday, July 11, announced that it now is producing its new Model 579 that features aerodynamic styling optimized for superior fuel efficiency and an interior that addresses operator comfort and productivity. The first 579 production vehicles are being built for Peterbilt and PacLease dealers.

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