About the Peterbilt 389
The Peterbilt Model 389 is the iconic long-hood traditional-styled Class 8 truck — the unofficial owner-operator favorite. Introduced in 2007 to replace the legendary Model 379, the 389 maintains the classic 'long nose' Peterbilt look with traditional fenders, separate cab, and a distinctive grille. Production ended with the 2024 model year, with the new Model 589 announced as its replacement. Cummins X15 is the most popular engine (Cummins has stronger owner-operator following than PACCAR). The 389 commands premium prices both new and used.

Design and engineering
Long-nose traditional design with a separate cab and 122-127 inch BBC (bumper to back-of-cab). Chrome accents are standard and often heavily customized by owner-operators. The 80-inch Ultraloft sleeper has a unique high-roof profile distinctive to the 389. Interior is leather-trimmed with real wood accents — far more premium than fleet-spec 579s. Manual Eaton 18-speed transmissions remain popular with this truck (most other modern Class 8s have moved to AMTs).
Generations and major changes
Market position and popularity
The 389 is the most-photographed truck in North America — show-truck culture revolves around this model. New 389 sales declined from ~7,000/year in 2015 to ~3,000/year by 2023 as more buyers moved to aerodynamic trucks. However, used 389s command premium prices — a clean 5-year-old 389 with Cummins X15 + Eaton manual can sell for $115K-145K. Production ended 2024, succeeded by Model 589.
Who buys this truck
Established owner-operators with 5+ years of experience. Heavy-haul specialists. Show-truck enthusiasts. Oilfield contractors who value mechanical simplicity. Older drivers who prefer traditional styling and manual transmissions.
Common problems and reliability notes
Cummins X15 emissions system at high mileage (same family as all Cummins). Detroit-style or PACCAR not common; almost exclusively Cummins on the 389. Lots of chrome means lots of corrosion management. Older 2007-2010 models had front suspension issues fixed by mid-cycle update.
