Peterbilt on Wednesday debuted virtually its next generation Model 579. The truck was unveiled via YouTube livestream, with 1,700-plus viewers tuning in worldwide.
Pete's on-highway flagship 579 was a clean sheet design when it arrived in 2012, and Peterbilt General Manager Jason Skoog said its update has been years in the making. "Five years of relentless focus on improving uptime, increasing fuel economy and taking driver comfort to new heights," he said at the truck's unveiling event.
The new 579, boasting a 7% fuel economy improvement over prior generation models, is the most aerodynamic and fuel-efficient Peterbilt model built to-date, enabled by a new exterior design that features a new sloped three-piece Metton hood, optimized aero components, and 2021 Paccar MX-13 and MX-11 engines paired with the Paccar transmission.
