General Motors (GM) has announced that it will be investing $918 million in four of its US manufacturing sites. $854 million of the investment will be used to prepare the facilities for the production of the company’s sixth-generation Small Block V-8 engine. The remaining $64 million will be invested in Rochester and Defiance, Ohio to support the production of castings and components for electric vehicles (EVs). The investment is part of GM’s efforts to strengthen its industry-leading full-size truck and SUV business while also supporting its growing EV product portfolio.

The Flint Engine Operations in Michigan will receive $579 million to prepare the plant for the assembly of GM’s sixth-generation Small Block V-8 engine. Bay City GPS in Michigan will receive $216 million to prepare the facility for the production of camshafts, connecting rods, and block/head machining. Defiance Operations in Ohio will receive $55 million, $47 million of which will be used to prepare the facility to build a variety of block castings to support future V-8 engine programs, and $8 million will be used to build a casting development cell for castings to support future EV strategies. Rochester Operations in New York will receive $68 million, $12 million for the production of intake manifolds and fuel rails for the future V-8 production at Flint Engine Operations, and $56 million for the production of battery pack cooling lines for EV production.

This investment brings GM’s US manufacturing facility investment commitments to over $37 billion since 2013, including the Ultium Cells LLC joint venture plants.

GM did not comment on the timing or schedule of production of the new V8 engine.
