Peterbilt Model 389

The Model 389 is the embodiment of Peterbilt’s heritage and the one true icon of the road. It remains the ultimate aspirational truck and the preferred reward truck for drivers in fleets large and small. Built for maximum appeal and enduring performance, the 389 delivers both in style. The 389’s timeless design features a host of advanced technologies. Its proven all-aluminum cab and industry-exclusive aluminum hood provide a durable and lightweight platform optimized for maximum load capacity. The 389’s interior features the highest quality materials in an ergonomic, driver-centric environment. The 389 is available as a day cab or sleeper for maximum versatility. The Pride & Class package is also available to add a stunning display of chrome accents, bright features, along with a traditionally styled louvered grille.


Exterior & Aerodynamics

The Model 389 offers a lightweight, all aluminum hood. The distinctive grille, with its punched oval pattern and one-piece polished aluminum crown, completes the look.

The Model 389 also features as options: proprietary roof fairings with trim tabs to reduce drag, 3” rubber Extender “Flair” on the sleeper which redirects airflow outward and around the trailer to close the gap between the tractor and trailer for maximum aerodynamic benefits, composite sun visor to increase fuel economy by providing less aerodynamic drag and maximizing protection against glare, and the mirror design features a tough, lightweight, chrome-plated housing, 4-way adjustability with vertical and horizontal adjustments, integral convex mirror and fully heated primary and convex mirror.


Peterbilt's SmartNav technology provides a touchscreen, Bluetooth, and voice control in your cab. GPS navigation shows you routes customized to the size and weight of your truck. Virtual gauges deliver real-time vehicle data.

The new digital display is pure Peterbilt: bold design, state-of-the-art technology, and class-leading functionality.


Peterbilt’s unique sleepers are built to deliver unparalleled fit and finish, quality and comfort. They feature plenty of storage, shelving, ample overhead lighting and a powerful HVAC. Available in 44", 58", 72" & 78" configurations.

The Model 389 is also available as a Day Cab to accommodate applications such as dumping and logging.
