 Peterbilt’s new medium duty truck family features the Model 535, Model 536, Model 537 and Model 548.  

2021 has been a significant year for Peterbilt as they unveiled their all-new lineup of medium duty trucks on April 7, 2021. Peterbilt’s new medium duty lineup sets the standard for versatility, productivity, efficiency and uptime. The new medium duty lineup announcement comes just two months after the reveal of Peterbilt’s New Model 579.  

During the five-year project, the engineers and designers at Peterbilt worked with consumers directly to understand their needs and deliver the quality that the company is known for. The new lineup includes the Model 535, Model 536, Model 537, and Model 548. 

Peterbilt will always go above and beyond to deliver trucks that are fine tuned for their specific application, not to mention have the durability and toughness to be around for a long time, said Jason Skoog, Peterbilt general manager, and PACCAR vice president.  

Maximum Efficiency and Versatility 

Built from a clean slate over five years, the Model 535 and Model 536 deliver a Class 5/6 truck specific to the customer’s everyday needs. Both the Model 535 and Model 536 are entirely customizable with options on hood length, roof height, composite or steel bumpers, and multiple options of fuel and DEF tanks.  

The cab is eight inches wider and boasts an impressive roof height of 74” and floor height of 40.5”, allowing three adults to be seated comfortably in the cab. There is 4.6 cu ft of overhead and door storage space, and three cup holders for driver convenience. The dash layout is completely customizable for any application. These new models also include a high-resolution 7” digital display that relays key information at a glance.

The all-new self-closing doors feature larger windows for increased driver visibilitya triple seal for enhanced NVH, and three opening positions. Stair-style steps and exterior grab handles make it easy to enter and exit the cab safely.  

For easy maneuverability, customers can choose from trucks that have a 107” or 109” Bumper to Back of Cab (BBC) measurement with a turning radius of 51 ft. 

“These trucks are a perfect fit for the growing lightweight lease, rental and pick-up and delivery markets with their versatility, excellent efficiency, and uptime,” said Skoog.  

Rugged Performance and Durability 

The Model 537 and Model 548 are designed for the  Class 7 and Class 8 segments. This class of medium duty trucks features a brand-new customizable chassis and a strong multiplex electrical architecture. With a seamless body builder integration, customers can customize the truck to fit their needs.  

Customers can choose from two hood options, a three-piece SMC aerodynamic hood for maximum visibility and a three-piece vocational Metton® hood featuring a stationary grille. Both hood options can use a variety of vocational and FEPTO bumpers to fit many applications.  

The new Model 537 and Model 548 provide maximum versatility and rugged performance. 

The bumper is front-mounted to the chassis with a drop-and-go feature for self-locating. Headlight, daytime running, and fog lights are included in the bumper’s light mounting options. The Model 537 and 548 also have two tow options and two license plate mounting options for enhanced versatility and customization.  

Customers who need a truck to meet more difficult and rugged jobs can fit the Model 537 and 548 with wide or standard track axles with superior wheel cut angels for an impressive shorter turning radius. . The rear suspension is available with taper-leaf or air leaf suspension rated from 12,500 to 40,000 pounds depending on single or tandem drive configuration. Like other trucks in the new medium duty lineup, the cab is 8 inches wider and offers increased storage space for drivers. 

Show-Stopping Uptime 

The complete lineup of new medium duty trucks features 3 cup holders and Peterbilt’s industry-leading customizable dash layout. The high-resolution 7-inch digital display sends information to the driver at a glance. Drivers can set their digital dash to display information via preprogrammed menu cards and toggle through options like trip summary, PTO functions, system checks, and ADAS with the company’s new multi-function steering wheel.
