General Motors plans to invest $48.4 million in its Bedford powertrain castings plant.
The investment will go to support GM's new Ecotec engine components.
The Bedford plant will produce transmission casings, converter housings and small gas engine blocks.
The new engines are designed to support hybrids and alternative fuels.
This comes in addition to the over $300 million already invested to the Bedford plant in the last five years.
The Bedford plant employs more than 600 workers.
