Saying Farewell to a Legend
For decades, the Peterbilt 379 stood as a symbol of American trucking pride. Its unmistakable long-nose design, chrome accents, and unmatched customization options made it a favorite among owner-operators and fleet drivers alike. Built for durability and style, the 379 earned its reputation as one of the most iconic trucks on the road. While production of this beloved model has ended, its legacy lives on through its modern successor the Peterbilt 579 which continues to raise the bar for performance, efficiency, and driver comfort.
The Iconic Peterbilt 379: A Brief Look Back
Produced from 1987 to 2007, the Peterbilt 379 quickly became a staple of long-haul trucking. Known for its straightforward maintenance, reliable build quality, and timeless aesthetic, it offered owner-operators the freedom to personalize every detail. Even today, the 379 remains a familiar sight across North America — a testament to its lasting craftsmanship and loyal following. But as technology advanced and emissions standards evolved, it was time for Peterbilt’s flagship to evolve too.
The 379 Is Not Available New Anymore
The Peterbilt 379 officially ended production in 2007, closing a remarkable chapter in trucking history. It was succeeded first by the Peterbilt 389, which carried on the traditional styling with modern upgrades, and later by the aerodynamically advanced 579. For those seeking a new Class 8 truck today, the 579 represents the next generation — built for performance, efficiency, and the demands of modern fleets.
Introducing the Peterbilt 579: The New Flagship
Launched in 2012, the Peterbilt 579 reimagined what a long-haul truck could be. Designed from the ground up with aerodynamics, safety, and driver comfort in mind, the 579 delivers on every front. Its spacious, wide-cab design improves visibility, accessibility, and overall driving experience — all while reducing fuel costs and environmental impact. For today’s fleets and owner-operators, the 579 is the clear continuation of the 379’s proud legacy.
Benefits of the 579 Over the 379
Unmatched Fuel Efficiency & Lower Costs
The 579 is powered by the PACCAR MX-13, MX-11 and the Cummins X15 engines, paired with DX-40 axles for optimized fuel economy and performance. Drivers experience superior
MPG, reduced noise, and lower emissions — all translating to real-world cost savings mile after mile.
Advanced Safety & Driver-Assist Technology
Safety is central to the 579’s design. Integrated Advanced Driver Assistance Systems (ADAS) include lane-keeping assist, side-object detection, collision mitigation, and pedestrian detection — all working to reduce fatigue and enhance confidence behind the wheel.
Superior Aerodynamics & Quiet Comfort
From its redesigned hood and air dams to its sculpted A-pillars and fairings, every detail of the 579’s exterior contributes to better airflow and reduced drag. The result is a quieter, more efficient ride with improved visibility and less strain on the driver.
Driver-Centric Cab Design
Inside, the 579 redefines comfort. Soft-touch materials, intuitive controls, LED lighting, and a large digital display enhance the driving experience. In the Ultraloft sleeper configuration, drivers enjoy up to eight feet of headroom, 70 cubic feet of storage, and space for a TV and microwave — turning long hauls into a true home away from home.
Simplified Maintenance & Fleet-Ready
Built with serviceability in mind, the 579 offers easier access to components, advanced diagnostics, and customizable specifications for any fleet. Reduced downtime means more uptime — and a lower total cost of ownership over the truck’s lifetime.
Real-World Adoption: The 579 in Action
Fleet operators nationwide are embracing the 579’s advantages. In 2025, Dynamic Transit announced plans to add 100 new Peterbilt 579s to their fleet, citing improved safety, fuel efficiency, and driver satisfaction. Each truck is projected to save approximately 3,750 gallons of fuel per year — a powerful example of how innovation and sustainability go hand-in-hand.
