The development follows GM’s decision to pull the plug on medium-duty truck production, they told Kyodo News.


Isuzu has been supplying diesel engines to GM for the trucks from its plant in Tochigi Prefecture and a joint factory with GM in Ohio. In 2008, it shipped some 2,000 and 8,000 engines to GM from the Tochigi and Ohio plants respectively.


But GM’s decision to stop buying a yet-to-be-known number of diesel engines from Isuzu will have only a ”small impact” on the Japanese carmaker because the joint US plant now produces 70,000 engines a year, an Isuzu official told the news agency.


GM is also likely to review the procurement of medium-duty trucks Isuzu produces under the GM brand for the US market, the sources said.
