Tested, refined and validated to reduce operating costs.
The ergonomic cab and generously sized sleeper are designed for maximum productivity and comfort.
Predictive Cruise improves fuel economy by up to 3%. The technology integrates the powertrain, cruise control and satellite mapping, enabling the truck to respond automatically to the road ahead, while neutral coasting uses the truck’s momentum to save fuel.
SmartLINQ™ delivers at-a-glance insights into the health of your entire fleet. SmartLINQ monitors more than 750 engine and aftertreatment diagnostic codes and delivers customized, 24/7 notifications with detailed diagnostics and recommended actions. The result is maximum uptime and trucks running at peak performance.
An intelligent navigation and communications center, SmartNavTM combines a full-color touchscreen with Bluetooth connectivity, voice recognition and productivity apps. The system features GPS navigation that calculates truck-friendly routes, real-time vehicle data, WiFi capability and up to four camera views.
Powered by four heavy-duty AGM batteries, Peterbilt’s SmartAir no-idle climate control system can provide high-power capacity to keep the sleeper cool for up to 10 hours. All while using 70% less fuel than diesel-based auxiliary power units and requiring no scheduled maintenance.
To create the EPIQ Aero Package, Peterbilt optimized everything from low rolling resistance tires, to the fairings and closeouts. Through computational fluid dynamics and thousands of miles of on-road validation, the 579 has achieved a 4% improvement in aerodynamics.
The PACCAR MX-13 engine features Compacted Graphite Iron in the block and cylinder head, enabling a higher power-to-weight ratio. With high pressure fuel injection and high-tech calibration, the engine saves up to 4% in fuel economy, as well as 150 pounds in weight.
The lightest axle in its class, the PACCAR axle saves up to 150 pounds of weight. Combined with the advanced design that boosts fuel economy, the PACCAR axle delivers fuel efficiency savings of up to 1%.
Custom-designed to integrate with PACCAR MX engines and axles, this automated transmission reaches new heights of efficiency. Saving as much as 205 pounds in weight, the PACCAR transmission is the lightest 1,850 lb-ft torque-capable heavy-duty automated transmission on the market.
Cutting-edge collision mitigation and driver assistance technology comes standard. Bendix® Wingman® Fusion™ combines camera, radar and brakes to build an integrated picture of road conditions, detecting hazardous situations and braking automatically in response to danger.
Air discs provide greater stopping power and better braking feel than drum brakes.
The safety of the 579 is tested relentlessly in the lab and then proven over millions of miles.
