General Motors will invest $5.4 billion over three years to improve its U.S. plants, including spending $783.5 million in three Michigan facilities, GM has announced.

The investments will help the company invest "in the people, tools and equipment to produce cars, trucks and crossovers that are built to win in the marketplace," said Alan Batey, GM's North America president.

Among the three plants, GM will invest $124 million in the Pontiac Metal Center, $520 million for tooling and equipment for future new vehicle programs at the Lansing Delta Township assembly plant, and $139.5 million for a new body shop and stamping facility upgrades at Pre-Production Operations in Warren. The investment in Lansing will allow GM to retain 1,900 jobs.

GM will detail the remaining $4.6 billion and identify plants involved over the next several months.
