Who owns and controls Duramax?
Tell the rest of the story and note at the bottom of the page the wages paid to the American workers who make them and the taxes paid by the Ohio plant where they are built that the rest of the American citizens don't have to make up by paying out additional from their present after tax incomes. GM owns and controls Duramax totally and it's only in the US building there of and the profits stay in the USA.
Note that in the previous link posted, there were identical development engines tested in both the USA and Japan. In the USA the engine was coupled to the Allison 1000 transmission for complete driveline actual testing.
