Navistar Inc. announced plans to begin offering over-the-air reprogramming of engine control modules for International brand trucks powered by its proprietary N Series engines.

John Correnti, a longtime member of the Navistar board of directors and the CEO of Big River Steel, died Aug. 18. He was 68.

Navistar said its competitors have declined to participate in a fuel-economy challenge the manufacturer proposed last month to be held at its proving ground in Indiana.

Caterpillar Inc. and Navistar International Corp. will terminate the arrangement under which Navistar builds vocational trucks for Caterpillar, and each company will move forward with independent lines of severe-duty trucks, the companies announced in separate statements.

Navistar Inc. said it will be the first truck maker to offer Eaton Corp.’s Procision line of dual-clutch transmissions for medium-duty applications.

Truck maker Navistar Inc. has finalized an agreement to supply Quality Cos., a subsidiary of truckload carrier Celadon Inc., with 9,000 Class 8 tractors during the next three years.

Truck maker Navistar Inc. said it has received an order for 1,050 of its International brand Class 8 on-highway tractors under a new three-year supply agreement with an unidentified leasing company.

Navistar International Corp. reported a smaller loss in its fiscal second quarter, driven by higher truck sales — particularly in the medium-duty sector — lower warranty expenses and cost reductions.
