Peterbilt Model 389

Peterbilt's Model 389 embodies the Peterbilt heritage and merges it with a proven design to create a legendary classic. Lightweight components, such as the all-aluminum cab and the industry's only aluminum hood, as well as a variety of lightweight front and rear suspensions, allow for increased load capacity. Aerodynamic enhancements for increased fuel savings all combine to ensure that your investment in a Peterbilt 389 pays dividends long after your initial purchase.

For maximum performance, the Peterbilt 389 is available with the fuel-efficient PACCAR MX-13 engine with power ratings up to 510 hp and 1,850 lb.-ft. torque. An optional fuel-efficiency package, as well as Peterbilt's exceptional reliability and performance, translate into an overall low cost of operation. For maximum versatility, the Peterbilt Model 389 is available as a day cab or a sleeper cab with low roof and UltraCab options in 44", 58", 72" and 78" configurations. Peterbilt 389 trucks continue to be an industry leader in quality, styling, performance and enduring value.
