Peterbilt Motors Co. has redesigned its Model 579 to improve aerodynamics, efficiency, comfort, technology and uptime.
Engineers and designers at Peterbilt worked with more than 50 customers to get their input on unique operations and needs and incorporated that into the new design.
The new 579 has a sloped hood and optimized aero components, as well as the new 2021 PACCAR MX-13 and MX-11 engines and PACCAR transmission, making the vehicle more aerodynamic and fuel-efficient.
Inside, drivers will experience a quieter cab and sleeper, additional storage, a new smart steering wheel and improved Bluetooth microphone. In addition, it has a 15-inch digital dash display. And the driver’s assistance systems include collision mitigation, lane departure warning and new lane keeping assist, among other safety features.
The 579 is available in a variety of cab sizes including the day cab configuration, the 80-inch UltraLoft sleeper and other sleeper sizes.
“The launch of the new Model 579 is a huge moment for Peterbilt and our customers,” said Jason Skoog, Peterbilt general manager and PACCAR vice president. “This new product is the result of five years of relentless focus on increasing fuel economy, taking driver comfort to new heights and maximizing uptime. This new truck delivers the next level of performance for our customers and continues Peterbilt’s legacy of being the ‘Class’ of the industry.”
