If you’re in the market for a reliable, comfortable, and fuel-efficient semi truck, the Peterbilt 579 remains one of our fleet favorites for good reason. Known for its aerodynamic design, advanced safety features, and long-haul comfort, the 579 delivers a powerful combination of performance and practicality. One of the most popular configurations, the Peterbilt 579 Ultraloft, adds a spacious sleeper cab that’s ideal for drivers who live on the road. Whether you’re running solo or managing a fleet, this model is built to keep your business rolling smoothly.
Why the Peterbilt 579 Stands Out
Peterbilt engineered the 579 with feedback from drivers and fleet operators to ensure it meets the needs of long-haul drivers. This model was built for drivers like you- who spend serious time on the road. The Peterbilt 579 offers excellent visibility, driver-focused technology, and a range of sleeper configurations, including the sought-after Ultraloft. Whether you’re running a single rig or managing a team, this truck delivers on performance and comfort.
