With the 579, the combination of aerodynamic innovation and powertrain optimization delivers confidence and efficiency for the most cost-conscious companies. Designed for the best aerodynamic performance, we used Computational Fluid Dynamics to test, refine and validate. Peterbilt's flexible
Aero Packages provide the right combination of fairings, skirts and closeouts to exceed application-specific aerodynamic requirements. Available in a day cab, or with detachable sleeper, that adds versatility and longevity of a second life for highest resale value.
Peterbilt now offers a compressed natural gas (CNG) configuration for the Model 579, providing short and long haul customers with the industry's most innovative, advanced vehicles with new state-of-the-art CNG systems. The Cummins Westport ISX12 G engine complies with all EPA 2013 and CARB emission regulations and is available with ratings of 320-400 horsepower and 1,150-1,450 lb. foot of torque. This CNG platform joins Peterbilt's family of alternative fuel vehicles, forming the industry's most comprehensive environmentally responsible lineup.
The Model 579 is built to last. We made the new aluminum cab solid and durable, with the highest quality fit and finish. An in-mold process embeds color directly onto the dash for a long-lasting finish that virtually eliminates fading, scratching and peeling. Electrical wiring carriages support wiring and reduce wear and tear, adding to the overall durability of the components.
The PACCAR MX-11 superior power platform has been integrated into Peterbilt’s best-in-class vehicles to provide customers maximum power and outstanding fuel efficiency. For optimized performance in virtually any application, the MX-11 has an output of up to 430 horsepower and 1,550 lb.-ft of torque. The combination of a Peterbilt truck and MX Engine offers long-term value through technologically advanced designs with lightweight materials that achieve excellent performance and superior fuel economy. The MX-11 provides longer service intervals, increased uptime, lower operating costs and higher resale value.
The Platinum interior features the revolutionary 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.
By designing our new cab around the driver, we've created an environment that drivers want to be in. The result is a spacious and ergonomic cab interior designed to put everything in reach and with the driver in mind. A new driver display package features large, easy-to-read, operation-critical gauges. The multi-function steering wheel features convenient access to cruise control and audio controls. Switches are backlit for enhanced nighttime visibility. Peterbilt's SmartNav system, an integrated telematics and infotainment system, provides real-time truck monitoring, truck-specific navigation, hands-free Bluetooth connectivity and satellite radio.
The Model 579 features a generously sized sleeper that combines comfort with productivity in an ergonomic business area. The bunk holds an 82-inch mattress, the largest in the industry, and provides the amenities of home that Peterbilt is known for. An innovative television mount accommodates flat-screen TVs on a convenient swivel. Abundant overhead storage spaces are thoughtfully designed and contribute to more flexible organization. Strategically placed LED lighting creates a pleasant ambiance for reading and working and saves battery life.
To ensure the headlamps on the 579 were the best and the brightest, our engineers traveled to 10 countries and logged countless hours of research, testing and improving. The results are headlamps and fog lamps that have the best down-road visibility and coverage in the industry.
Designed for a consistent beam distribution and exceptional overall road coverage, our headlamps deliver a homogenous pattern and less eye fatigue. A large, one-piece windshield aids visibility and standard air-disc brakes significantly reduce stopping distances.
