Navistar Heavy Duty – other on-highway engines: the collective page of the A range outside the named models, EPA certification data from the MaxxForce era 2012 to 2016, 200 to 550 kW for International trucks
Navistar, headquartered in Lisle, Illinois, operated until the majority takeover by Volkswagen subsidiary Traton in 2021 as International Truck and Engine Corporation, an independent maker of heavy trucks under the International brand. This page gathers the on-highway engines from the US EPA certification data that the register could not assign to a named range; every model designation from A200 to A450MT belongs to the A range, and the engine-family codes consistently contain the manufacturer code NVX. The 2012 to 2016 model years fall in the period when Navistar still developed its own truck engines under the MaxxForce name, before the group switched to Cummins engines in 2017 because of problems with its own exhaust aftertreatment approach.

The register lists here 45 versions with 200 to 550 kW rated output at 1,600 to 2,600 rpm, with electronic direct injection and diesel as fuel. Maximum torque ranges from 540 to 1,850 Nm at speeds of 900 to 1,600 rpm.
The A range covered the heavy and medium-heavy truck segment of Navistar's International models and competed directly with Cummins, Detroit and PACCAR MX engines; the well-known series problems with the in-house exhaust-treatment approach in this era are among the reasons Navistar later abandoned its own engine programme and, as part of Traton today, again relies on outside engines.
On a used purchase from these model years, what matters especially is the service history of the exhaust aftertreatment and any modifications made, the condition of the injection system and turbocharger, the cooling system and charge-air cooler, and matching the engine-family code to the unit actually fitted; spares run through the International/Navistar dealer network.
