About the International HX Series
International's severe-service conventional, the HX debuted in 2016 and was fully redesigned in November 2020 as the first new product under the Navistar 4.0 strategy and Project Compass. The set-back-axle HX620 can be ordered with the Cummins X15 making up to 605 hp and 2,050 lb-ft, rides on a 12.5-inch by 0.5-inch single-rail frame rated at 3.5 million RBM, and uses International's programmable Diamond Logic electrical system for body integration.
About the Western Star 49X
Launched in 2020 as the first of Western Star's clean-sheet X-Series, the 49X introduced the industry's first high-strength single-channel frame rail rated at 3.8 million RBM with no insert, and was the first Western Star ever offered with the Detroit Assurance suite of active safety systems. It was built to replace the long-running 4900 vocational flagship while coming out roughly 350 pounds lighter.
