Built to work hard
No other truck measures up to the harsh demands of the refuse industry like Peterbilt’s rugged Model 320, a low-cab forward vehicle that is the perfect fit for this challenging application. A huck-bolted aluminum cab features lap seam construction on a zinc-coated steel sub-frame for durability and corrosion resistance. Bulkhead-style doors provide years of virtually watertight performance.
Fuel-efficient, Reliable and Environmentally Sound
The Model 320 diesel engine lineup spans from the lightweight, fuel-efficient PACCAR PX-9 to the powerful Cummins ISX12 with ratings up to 400 horsepower and 1,650 lb-ft. of torque. For natural gas applications, the Model 320 is available with a choice of the Cummins Westport ISL G rated at 320 horsepower and 1,000 lb-ft of torque or the Cummins Westport ISX12 G with ratings from 320-350 horsepower and 1,150-1,350 lb-ft of torque. These spark-ignited engines are capable of running on either Compressed Natural Gas (CNG) or Liquefied Natural Gas (LNG). With the flexibility to mount tanks either on the rail or integrated into the body, the Model 320 allows for maximum use of space when integrating a body for a variety of applications.
The Model 320 cab is available in left-hand, right-hand and dual drive with right-hand stand-up configurations. An industry-leading, 65-degree cab tilt enhances maintenance and serviceability. The Model 320 offers a full range of axle selections in single, tandem or tri-drive configurations, plus a full complement of tag and pusher axle options and a tandem steer front axle configuration rated at 36,000 pounds. For heavier applications, optional frame liners are available. The battery box is lightweight, compact and fender-mounted to free up valuable frame space.
Where Form and Function Meet
The Model 320’s new interior features an ergonomic dash design with LED backlit gauges, a driver information display for critical vehicle data and rocker switches within easy reach for maximum driver comfort and productivity. A new headliner includes overhead controls for the improved HVAC system while the large center console facilitates easy installation and convenient access to body controls. New cab-corner windows and a lowered dash significantly improve overall visibility. A 90-degree door opening with three grab handles on each side and an impact-resistant, bolt-on step provides easy entry and exit.
