International Motors – other heavy-duty highway engines: the collective page of the A and MT ranges outside the named models, 275 to 515 kW, model years 2017 to 2026, direct injection throughout
International Motors LLC, trading as Navistar International until the 2024 rebrand, headquartered in Lisle, Illinois, has belonged since the 2021 takeover to the Volkswagen-controlled Traton commercial-vehicle group; the company is one of the long-established US makers of heavy truck diesel engines for road transport. This page gathers the engines the register could not assign to a named range, with model designations such as 350HP, 400MT and 450MT as well as the A series from A365 to A410MT; the leading number on some models clearly corresponds to horsepower output.

The register lists here 65 versions with 275 to 515 kW rated output at 1,700 to 2,700 rpm, all with direct injection and ultra-low-sulphur diesel, model years from 2017 to 2026, torques from 700 to 1,850 Nm at 900 to 1,600 rpm.
Engines of this power class drive heavy tractor units and distribution vehicles across the International truck ranges; in the North American heavy highway-engine market, International Motors competes with Cummins, Detroit Diesel, PACCAR MX and the Volvo and Mack engines.
On a used purchase, mileage and service records count, the condition of the turbocharger, injection pump or injectors, the cooling system and charge-air cooler, and depending on model year the exhaust aftertreatment with particulate filter, SCR catalyst and AdBlue dosing; spare parts run through the International authorised-workshop network.
