The ‘Paccar MX-13’ with additional low-NOx aftertreatment is now being offered with Peterbilt’s Model 579, 567, and 589 trucks and with Kenworth’s T680, T880, and W990 trucks.

The TX-12 PRO automated transmission is now available with the heavy-duty Peterbilt Model 567 and 579 and the Kenworth T680 and T880.

The parent of DAF, Kenworth, and Peterbilt announced record sales revenue of USD35.13bn in 2023, a 22% improvement on its performance in the year before (USD28.82bn).

Walenczak is an internal promotion, having served two years as Kenworth's assistant GM for sales and marketing.

Built for the U.S. Department of Energy’s SuperTruck II programme, the prototype truck, described by Paccar as a “testbed for future product technologies”, was developed in order to improve freight ton efficiency by 100% compared to a 2009 baseline.

The transmission is paired with the Cummins X15 engine, designed for peak performance for on-highway heavy-duty vehicle (HGV) applications.

Harry Kent and Edgar Worthington have been honoured for their contributions to the American trucking industry, which coincide with the company’s centenary celebrations.

In 1923, founders Harry Kent and Edgar Worthington incorporated the Gersix Motor Company as Kenworth, the company has manufactured over 1.3 million trucks to date.

Both companies will be making Class 8 electric trucks using fuel cell drive systems developed by Japanese firm Toyota, with Kenworth aiming to begin customer deliveries next year.

The deal will mark the first time that ZF’s OnTraX system for lane keeping assistance has been installed in a commercial vehicle platform in North America.

The owner of DAF, Kenworth and Peterbilt reported revenues of USD28.82bn, earnings of USD3.01bn and a net income of USD921.3m.

Paccar says that select Kenworth and Peterbilt trucks built from 2024 onwards will be installed with Virtual Vehicle, an edge computing platform that provides access to telematics, real-time data and third-party applications directly from the vehicle.
