Peterbilt Model 579
The Peterbilt Model 579 is the most technologically advanced and fuel-efficient truck the brand has ever built. Designed for long-haul and on-highway applications, the Model 579 combines bold exterior styling with a spacious, driver-focused interior. With enhanced aerodynamics and cutting-edge features, this Class 8 heavy-duty truck sets new benchmarks for safety, comfort and efficiency.
The Peterbilt 579's aerodynamically optimized grille, bumper, air dam, mirrors and A-pillar fairing not only look sharp but deliver up to a 7% improvement in fuel economy. Inside the cab, a 15" digital display integrates seamlessly with Advanced Driver Assistance Systems (ADAS) such as adaptive cruise control, lane keeping assist and road sign recognition to make driving the Model 579 a pleasure. Under the hood, the integrated PACCAR Powertrain delivers superior performance and a lower cost of ownership. Engine options include the PACCAR MX-13 or MX-11 diesel engine, as well as the Cummins X15 diesel and ISX12N or L9N natural gas engines — giving fleets the flexibility to choose the right power for their needs.
