Peterbilt's low-cab forward Model 320 ergonomic interior unveiled

The ProBilt interior features ergonomic improvements, system enhancements and improved overall visibility for maximum operator comfort.


The ProBilt interior is available in Titanium Gray.

The foundation of Peterbilt's rugged Model 320 is the huck-bolted aluminum cab that features lap seam construction and bulkhead style doors on a zinc-coated, steel subframe for maximum durability and corrosion resistance. In applications where stopping distance is critical, the 320 comes standard with air disc brakes, which improve brake life and reduce service time.

An industry-leading, 65-degree cab tilt provides technicians easy access to key service points for improved serviceability and reduced downtime. Use of LED marker lights, instead of incandescents, extends service intervals.

A 90-degree door opening with multiple grab handles and an impact-resistant, bolt-on step provides easy entry and exit. The exclusive use of taper leaf front springs provides an increasingly smooth ride. An impressive 44-degree wheel cut allows drivers to easily maneuver in congested urban environments. The Model 320 offers a full range of axle selections in single, tandem or tri-drive configurations, plus a full complement of liftable axle options and a tandem steer front axle configuration rated at 36,000 lbs.

In addition, the Model 320 is available in Compressed Natural Gas (CNG) or Liquefied Natural Gas (LNG) with the Cummins Westport ISL G and ISX 12 G Engines. Both configurations provide flexibility to locate the fuel tanks either off the frame rail or integrated with the body.
