General Motors Co. introduced new investments of almost $332 million for four of its GM Powertrain plants, and added $46 million to previously announced investment programs at two more operations. Two GM metalcasting plants will be involved in the capital programs.

The larger investment program aims to add capabilities for production of GM’s new Ecotec small gas engine, a new V6 engine, a new eight-speed transmission, and new tooling for a current six-speed transmission design.

The second set of outlays will support ongoing projects to support production of the new V6 engine.

The GM Bedford Castings plant in Bedford, IN, an aluminum melting, diecasting, and permanent mold foundry that produces transmission cases and converter housings will receive$29.4 million to update it operations. This will include $19 million to start production of components for the small gas engine and $10.4 million to produce components for GM’s new 8-speed and existing 6-speed transmissions.

Two years ago the Bedford plant was announced as the site of a $49-million program to install new tooling and production equipment for the 8-speed transmission program, and a small engine product that had not yet been announced.

The new investment program also includes $215 million for GM’s Flint engine plant, where the small Ecotec gas engines will be built. Also, the plant will update its tooling for the V6 engine it is producing now. 

GM said more details about production plans for variants of the new Ecotec engine would be announced later.  In the past, GM has said the new engine would replace three series of small engines with a new, modular design. The engine was co-developed with Shanghai Automotive Industry Corp. (SAIC), Shanghai General Motors (SGM), and the Pan Asia Technical Automotive Center (PATAC).
