Peterbilt 579

Description

The most technologically advanced, fuel-efficient Peterbilt – ever

The Model 579 is the result of extensive customer input and a commitment to technological advancements. Through over 100 user tests and interviews with drivers, technicians, and safety managers, we have created a sleek, comfortable, and fuel-efficient truck that meets the diverse needs of the industry.

This model incorporates Advanced Driver Assistance Systems (ADAS) technology, providing critical truck systems information and enhancing driver safety. The Bendix Fusion system is recently updated to include pedestrian detection, lane-keeping assist, and side object detection, further improving overall safety on the road. The electronic park brake helps to potentially prevent rollaways by automatically applying the parking brakes if the driver forgets. When the Rollaway Mitigation activates, it engages the park brake and alerts the driver.

Experience the most advanced, fuel-efficient Peterbilt ever created – the Model 579. With its cutting-edge technology and customer-driven design, this truck sets new standards for safety, comfort, and efficiency.
Carries a heavy payload with a lighter payout at the pump

The PACCAR powertrain offers an integrated solution for maximizing MPG and payload capacity
It combines durable PACCAR MX engines and DX-40k tandem drive axles
The integration of these components allows for effortless pulling, improved efficiency, enhanced fuel economy and increased driver comfort
The PACCAR MX-13 and PACCAR MX-11 engines utilize a combination of proven technologies and state-of-the-art innovations
These engines are designed to maximize MPG and achieve the lowest possible fuel consumption, emissions and noise levels
They incorporate variable speed engine components and optimized combustion
PACCAR MX engines deliver exceptional reliability and proven performance, whether in linehaul or vocational heavy-duty truck applications
Other powertrain highlights include:

Gear ratio coverage for slow-speed maneuvering
High-performance thru-shaft pinion design that transfers full engine power straight to the road
Fuel system efficiently optimizes combustion and decreases noise
Broad torque curve that delivers up to 1,850 lb.-ft. and peak torque at low rounds per minute (RPM)
Long-life maintenance intervals
The new PACCAR TX-12 PRO automated transmission is designed to be versitile and efficient, while also remaining tough and durable. It is engineered to operate with engines that have up to 1,000 lbs.-ft. of torque and a maximum Gross Combination Weight Rating (GCWR) of 70,000 lbs.

More TX-12 Pro Features and Benefits include:

Dual PTO functionality to power multiple hydraulic devices simultaneously
New Extreme Duty Clutch for improved low-speed maneuvering with higher loads
Rock Free Mode helps rock the truck free from mud, sand or snow
Off-Highway Calibration enables shift points that are tuned for changing off-highway conditions with a bias toward shifting less often
Secondary Configuration for a tailored driving experience that accounts for toggling between two calibrations for the load or terrain
Aerodynamics enhance the efficiency

The Model 579 offers the most advanced aerodynamic features and packages to improve fuel economy
The bold grille and bumper maximize aerodynamic performance, while the lower-sitting front end enhances visibility of the ground in front of the truck
The air dam below the bumper further improves aerodynamics without compromising ground clearance
Sculpted mirror heads and arms not only improve aerodynamic efficiency but also allow the driver to see the top of the trailer while backing up
The A-pillar fairing directs air across the side of the cab to improve aerodynamics, reduce noise and enhance driver comfort
Wheel well closeouts accommodate a wider range of tire options
Tip-out chassis fairings provide convenient tool-free access to batteries, fuel tanks, auxiliary power units (APUs) and after-treatment systems
The Model 579 features industry-leading Light Emitting Diode (LED) headlamps with superior light coverage, uniformity and a built-in heater for clear lenses in inclement weather
An optional LED fog, driving and directional light system enhances visibility in different weather and road conditions by improving high-beam output and automatically activating a cornering light with the turn signal
