Peterbilt Motors Co. unveiled a 72-inch low-roof sleeper configuration for its Model 589 tractor on March 8.
Peterbilt said this sleeper configuration includes a full-height wardrobe and passenger side microwave tray, along with a driver side workstation and storage cabinet. Optional features includes a right-hand cubby, a refrigerator and an above-the-bunk shelf.
Added to that are four standard 12-volt outlets, factory-installed inverters, aftermarket inverter installation provisions and 22-inch-flat-screen mounting and electrical provisions, the original equipment manufacturer said.
The Paccar Inc. subsidiary is responding to customer appetite with the introduction of this low-roof sleeper option for the Model 589, Jake Montero, Peterbilt assistant general manager, sales and marketing, told Transport Topics.
This latest version of the Model 589, a truck that was launched in May 2023, is the third low-roof configuration option the truck maker has introduced in recent weeks. Peterbilt on Feb. 23 rolled out two fresh configurations for car carrier cabs — the Model 567 UltraLow Roof Day Cab and the Model 589 UltraLow Roof 58-inch Sleeper.

The 72-inch low-roof option completes the Model 589 sleeper lineup, Montero said.
That portfolio includes the following:
- a 44-inch low-roof option;
- a 58-inch low-roof option;
- a 58-inch high-roof configuration;
- the new 72-inch low-roof option
- a 72-inch high-roof option
- an 80-inch high-roof option.
Powertrain options for the 589 are the MX-13 and X15 engines, which can be paired with Eaton RT and FR Manual, TX-12/Endurant, TX-18/Endurant XD or Allison 4000/4500/4700 transmissions.
Peterbilt offers the 589 in on-highway, medium-duty, vocational and car carrier configurations.
Production of the 589 began in January. The model has a wider cab platform compared with its predecessor, as do other trucks in Peterbilt’s lineup. With the Model 589, the amount of room available increased to 2.1 meters from 1.9 meters. Around eight inches between the seats were added as well as more space from front to back.
Peterbilt’s flagship Model 579 model uses the wider cab platform.
The Model 589 replaced the legacy Model 389, which debuted in 2007. At least 110,000 of the Model 389 trucks were sold during the truck’s lifetime.

The company on March 12 introduced the Paccar TX-12 Pro automated transmission for the Model 579. It was also made available for the first time in the Model 567.
The TX-12 Pro automated transmission operates with engines of up to 1,700 pound-feet of torque and a maximum gross combination weight rating of 70,000 pounds.
Peterbilt said some of the features of the TX-12 Pro include dual power takeoff functionality to power multiple hydraulic devices simultaneously; an extreme duty clutch for improved low-speed maneuvering with larger loads; a rock-free mode; off-highway calibration with shift points tuned for changing off-highway conditions with a bias toward less-frequent shifting; and secondary configuration to enable toggling between two calibrations for the load or terrain.
“The addition of the Paccar TX-12 Pro automated transmission enhances Peterbilt’s ability to provide the best-performing trucks in the industry with improved efficiency, low-speed maneuverability and improved reliability to our vocational customers,” said Montero.
