Bottom Line Up Front
Kenworth and Peterbilt are both owned by PACCAR, yet they look, feel, and cost different enough that drivers often pick one over the other.
Kenworth vs Peterbilt Semi Trucks: Design, Performance & Price Differences
Image: Kenworth vs Peterbilt Semi Trucks: Design, Performance & Price Differences – Performance Comparison and Specifications
Design & Looks
At first glance, Kenworth trucks tend to have a sleek, aerodynamic profile. The W900 series is famous for its classic long nose, while newer models like the T680 feature a modern cab that reduces wind resistance.
Peterbilt, on the other hand, leans toward a rugged, customizable appearance. The iconic 389 model keeps the long‑nose heritage alive, but the 579 offers a more squared‑off cab that many owners say feels more “truck‑like.”
Both brands let owners choose chrome trim, paint options, and interior upgrades, but Peterbilt’s aftermarket market is larger, giving owners more ways to personalize their rig.
Performance & Mileage
Both brands share PACCAR’s reliable diesel engines, but the tuning differs. Kenworth often pairs its trucks with the PACCAR MX-13 engine tuned for higher fuel efficiency, especially in the T680 and T880 models. Drivers report up to 8 mpg on highway runs.
Peterbilt usually offers the same MX-13 but tuned for a bit more torque, which can be handy when hauling heavy loads in hilly terrain. Mileage numbers hover around 7‑7.5 mpg, a shade lower but still competitive.
Both brands support advanced aerodynamics packages, automatic transmission options, and telematics that help fleet managers monitor fuel usage.
Price & Rivals
Pricing depends on configuration, but a base Kenworth T680 starts around $150,000, while a similarly equipped Peterbilt 579 starts near $155,000. Add‑ons like premium seats, sleeper cabs, or advanced safety tech can push both into the $180,000‑$200,000 range.
When you compare them to rivals like Volvo VNL or Freightliner Cascadia, Kenworth usually edges ahead on fuel efficiency, while Peterbilt often wins on driver comfort and customization.
