Peterbilt innovations reduce operating costs.
A traditional cab design with aerodynamic enhancements for increased fuel savings ensures your investment in the Model 389 pays dividends long after the initial purchase price. An optional fuel-efficiency package as well as Peterbilt’s exceptional reliability and performance translate into an overall low cost of operation. Optional day cab configuration provides application-specific versatility.
The PACCAR MX-13 Engine brings a new level of innovation through industry-leading quality, exceptional reliability and proven performance. The combination of a Peterbilt truck and MX-13 Engine offers a long-term value through technologically advanced designs with lightweight materials that achieve excellent performance and superior fuel economy. The MX-13 provides longer service intervals, increased uptime, lower operating costs and higher resale value.
Peterbilt’s all-aluminum cab is not only extremely durable, it’s also lightweight to allow for increased payloads to maximize performance and profitability. The cab is huck-bolted with lap seam construction and bulkhead style doors for toughness, and corrosion resistance offers years of durable performance. A lightweight and durable hood is the industry’s only all-aluminum hood, with a rugged stainless steel grille that features a distinctive punched oval pattern and a one-piece, polished aluminum crown.
The Premium interior features the revolutionary new SmartNav system, an integrated, infotainment system. SmartNav features a 7-inch touch screen that provides real-time vehicle monitoring, a truck-specific Garmin navigation system, hands-free Bluetooth® connectivity, voice recognition, a fully integrated audio system with satellite radio as well as MP3, USB and iPod® capabilities.
Comfortable and versatile.
The Model 389 offers a variety of front and rear suspension options including Peterbilt proprietary units that are lightweight for increased load capacity. Peterbilt’s proprietary Front Air Leaf Suspension is lightweight and features a 20% improvement in ride quality over taper leaf suspensions for an extremely soft ride.
The Model 389 features an ergonomic dash that puts everything within reach of the driver and improves visibility. The charcoal finish reduces glare and resists scratches and fading.
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.
Halogen reflector, aluminum headlamps are protected with an impact-resistant lens. The bright, consistent beam pattern helps reduce driver fatigue. A robust gas spring design allows for easier opening and closing of the battery/tool box and helps ensure items are stored safely and securely. Air disc brakes and electronic stability control are now standard and offer the best stopping distances.
