Peterbilt Expands 579 Line

Peterbilt 579

Peterbilt introduced a mid-length BBC configuration to the Model 579 product line at the Mid-America show today. The new lightweight 117-in. BBC offers excellent maneuverability and visibility, the company says, aiming the truck at weight-sensitive customers such as regional and bulk haul applications.

The new mid-length Model 579 can be configured as a day cab or with the full range of detachable Peterbilt sleepers, including a new 80-in. model — the largest sleeper in Peterbilt’s history.

The 117-in. BBC hood features a low-cost-of-repair three-piece design. It’s dramatically sloped for enhanced aerodynamic efficiency, and when combined with the 579’s panoramic-style windshield, is said to offer “exceptional” forward vision. The set-back front axle optimizes weight distribution.

The mid-length Model 579 will be available with the 2013 PACCAR MX-13 engine in June.

Peterbilt also introduced a new cab interior for the Model 587 at the show. Among other features, it sports new gauges positioned to maximize usability. The new 5-in. color Driver Information Display communicates critical vehicle operational information to the driver. Also, there’s an efficient new pedal design with floor-mounted feel and actuation, as well as a new air-over-hydraulic clutch system that reduces pedal effort by 50%. And there’s now all-LED interior lighting, which dramatically extends bulb life and reduces battery power requirements.
