Massey Motor Freight of Nacogdoches, Texas acquired the 100,000th model, a limited-release ‘Model 389X’ special edition vehicle.

The Primaax EX is recommended to customers who need trucks for vocational and heavy haulage applications.

The TX-18 Pro automated transmission will come with two new features: Off-Road Calibration and Rock-Free Mode.

The Model 589 also features Peterbilt’s latest advanced driver assistance systems, including collision mitigation and predictive cruise control to improve safety and fuel economy.

The truck – a Peterbilt Model 579 – featured a Cummins ‘X15H’ engine, providing up to 500 horsepower (372 kW) and up to 1,900 lb-ft torque.

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 programme - which covers servicing of Paccar MX engines, electrical systems, and braking and suspension systems - will provide students with nine factory-trained technician credentials, which Peterbilt claims will help fast-track them to careers at one of its North American dealerships.

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.

The ‘389X’, available in day cab or 72”/78” Sleeper configurations, is a limited-run model with a distinctive black design of only 1,389 units, available to order from Peterbilt dealers.

The X15N, the newest in the X-Series of natural gas engines, will be offered in heavy-duty trucks manufactured by PACCAR subsidiaries Kenworth and Peterbilt.
