Navistar has launched a new generation of its International HX Series severe-duty model in North America.

Navistar says that the new HX Series is “our most comfortable, durable, technologically integrated and driver-focused severe service truck ever.”

The new HX comes standard with an International A26 engine, rated up to 500 horsepower – or the option of a Cummins X15, with up to 605hp and 2050 lb ft of peak torque.

There’s the choice of an Eaton Roadranger manual gearbox, an UltraShift AMT or an Allison 4000 Series auto. International axles are mated with the new Hendrickson HAULMAAX HMX-EX suspension.

Navistar says the redesigned HX cab says will “perform in even the most punishing vocational applications.”

A stronger three-piece bonnet is designed to provide improved forward vision and dual external air cleaners offer improved filtration in dusty environments.

Navistar says that the HX has a larger cab, providing improved comfort, a premium driver seat, best-in-class aircon system and larger, power windows. 

It also has Bendix driver assist technology to improve driver awareness.

Dual steering gears improve on-site manoeuvrability and advanced ABS improves traction and safety.
