Peterbilt 589

The Peterbilt 589 is the flagship extended-hood conventional of the Peterbilt range, introduced in 2023 as the successor of the 389. It keeps the chassis of the 389 but takes the wider 2.1 metre cab shared with the 579, the 567 and the medium-duty trucks, while holding on to the flat hood of its predecessor, updated to fit the different cab. Peterbilt lists it in on-highway, medium-duty, vocational and car carrier applications. The company's model list gives 2024 as the start of its run, while its history section gives 2023 for the introduction.
