Peterbilt 579 Class 8 truck has been updated and includes a day cab version. The heavy truck pairs either a 2021 Paccar MX-13 or MX-11 engine with a Paccar transmission.
A redesigned Peterbilt truck exterior features a new sloped Metton hood that is narrower and more resistant to damage. Headlights are improved halogen or optional LED. A three-piece bumper integrates the forward radar cover for collision mitigation, with a larger aerodynamic air dam, and provides both protection against damage and lower replacement costs. Optimized aero components include aero mirrors, fairings, side skirts and closeouts with the revised A-pillar vane redirecting airflow around the windshield, which reduces friction and helps deliver a 10 percent noise reduction in the cabin.
15-inch digital dash display fully integrates with electrical and safety systems found on the new 579 including the Bendix Fusion Advanced Driver Assistance System. It features a fully customizable user interface that drivers can control through one of three different Drive View Zones. Minimized View eliminates everything but the speedometer and tachometer for minimal driver distraction. Basic View represents traditional information found on analog dashes with Air & Oil Pressure, Fuel & DEF level and Water temperature all prominently displayed along with a speedometer and tachometer. The Enhanced View builds upon the previous views displaying the maximum number of gauges from a list of over 30 information sources. The display can be customized to shown information to suit individual needs.
Prior to trip departure, the display has the ability to run through a visual systems check, inspecting 13 systems and providing a green checkmark with each passed test. Post-trip, a detailed trip information screen provides a breakdown of important metrics of the most recent journey.
Incorporated within the display is the Advanced Driver Assistance Systems (ADAS) with integrated camera and radar technology that enable collision mitigation, overspeed alerts, and lane keep assist to be displayed prominently in the center of the display. The Digital Vision System provides drivers vastly enhanced, camera-enabled vision around the truck at all times including at night and during inclement weather.
