GM expects the new plant to save it $40M in travel costs, as well as money on the repair of parts that are damaged while in transit.
The facility is part of GM's strategy of improving its profitability by slashing logistics expenses.
"We spend billions a year on logistics," said GM CEO Dan Akerson. "Think about that, billions. Any savings I can get...goes right to my bottom line and makes us more competitive."
One of the factors that has facilitated the new plant are the labor contracts that allows GM to pay new workers lower wages, said Tim Lee, the company's manufacturing chief.
