The Peterbilt 379 is a Class 8 truck produced by the Peterbilt division of PACCAR from 1987 to 2007. Alongside the similarly-styled Kenworth W900, the 379 was an extended-hood conventional-cab truck marketed primarily to owner-operator drivers. Replacing the 359, the 379 would become the flagship of the Peterbilt model line. During its production, it would be joined by the more aerodynamic 377, 386, and 387.

In 2007, the Peterbilt 379 was replaced by the Peterbilt 389, which is distinguished with newer-style headlights and an even longer hood. To commemorate the end of production in 2007, the last 1000 vehicles produced on the assembly line were designated as Legacy Class 379.


The largest highway truck sold by Peterbilt at its launch, the 379 was produced in two configurations. The standard hood created a BBC (bumper to back of cab length) of 119 inches. To allow for larger engines and radiators, an extended hood configuration was available, which made for a 127-inch BBC. Although sharing the bare cab structure with the 359, the 379 was produced with a slightly larger windshield and horizontally-mounted windshield wipers.


Throughout its production, the 379 was equipped with the most powerful versions of the engines offered in Class 8 on-highway vehicles. The turbodiesel engines included the Caterpillar C-11, C-12, C-13, C-15, C-16 and the 3406-(B,C,E,P and EWS), Cummins the Big Cam NTC, N-14, ISM, ISX, ISMe5, ISXe5, Signature 600, and Detroit Diesel 60 series and 90 series.
