This week, Petebilt gave the world a look at the new Model 579, which the company designed to be more aerodynamic and fuel-efficient.

On February 3, Peterbilt debuted next evolution of their flagship Model 579, which was first introduced to the public in 2012. The company says that the redesign took five years and incorporated feedback from more than 50 customers to create “the most reliable truck ever designed by Peterbilt.”

The company shared highlights of the new Model 579 in a news release:

Peterbilt designers and engineers have delivered the most technologically advanced truck Peterbilt has ever built. The new 579 is also the most aerodynamic and fuel-efficient Peterbilt thanks to the new exterior design featuring a new sloped hood and optimized aero components, as well as the new 2021 PACCAR MX-13 and MX-11 engines and PACCAR transmission.  Improved comfort will have drivers feeling right at home on the road with a 10% quieter cab and sleeper, additional storage, a new smart steering wheel and an improved Bluetooth microphone. Highlighting the New 579s innovative technologies is a class-leading 15” Digital Dash Display, delivering all the information drivers need in a clean, intuitive interface. In addition, the new 579 features Advanced Driver Assistance Systems providing drivers the latest safety technologies in the form of collision mitigation, lane departure warning and the new lane keeping assist (LKA), among others.
