Launched in 2012 as Peterbilt's on-highway flagship, the aerodynamic Model 579 anchors the EPIQ fuel-efficiency package and in 2018 gained the integrated UltraLoft sleeper, which gives drivers a full 8 feet of standing headroom and roughly 70 cubic feet of storage. It is the truck most fleets pick when they want Peterbilt's best highway fuel economy in a Class 8 tractor.
