In addition to modernizing its Wentzville, Missouri plant, the automaker plans to invest $275 million across its Spring Hill, Tennessee manufacturing complex.
DETROIT—In a July release, General Motors Company (GM) announced more than $430 million in combined investments across two U.S. manufacturing sites. The investments include approximately $157 million in GM’s Wentzville, Missouri assembly plant and $275 million across its Spring Hill manufacturing complex in Tennessee, the company said in the release.
“These announcements are part of GM’s broader commitment to strengthen domestic manufacturing and American innovation,” the release stated. “This year alone, GM will spend approximately $9 billion across its U.S. manufacturing footprint, along with more than $7 billion on U.S. research and development.”

At Wentzville, GM is making a $157 million investment focused on paint and modernization work, including new paint processing equipment, an estimated 28,000-square-foot expansion, and major refurbishment inside the existing paint shop. The investment is designed to help keep Wentzville modern and competitive over the long term while reinforcing the plant’s role as a key part of GM’s manufacturing footprint, the company said.
General Motors’ Wentzville plant builds the Chevrolet Colorado and GMC Canyon midsize trucks alongside the Chevrolet Express and GMC Savana full-size vans. The site, reported to employ more than 4,000 people, has deep roots in the community. Together, the paint and modernization work is said to reflect continued confidence in the plant, the workforce, and Wentzville’s long-term importance to GM’s U.S. manufacturing network.
“Strong partnerships are one of the reasons Wentzville continues to grow and thrive,” said Mayor Nick Guccione, in a statement. “GM’s continued investment in the Wentzville Assembly plant demonstrates its commitment to our city and our region, and reinforces that Wentzville is a place where businesses can find long-term success. We’re grateful for GM’s continued investment in Wentzville and the positive impact it has on our community.”

At Spring Hill, GM’s more than $275 million in investments include more than $150 million in assembly to support the recently announced Cadillac XT6, and $125 million in GPS to support the future of the 2.7L engine program. Once the XT6 is added, Spring Hill Assembly will become a five-vehicle operation, the company said.
The two announcements are reported to show how GM is “continuing to invest in flexible, long-term manufacturing sites that can support current demand, future launches, and a stronger overall production footprint.”
“These announcements are about more than any one program, product, or facility,” said General Motors Senior Vice President of Global Manufacturing Mike Trevorrow, in a statement. “They show how we’re building flexible, long-term manufacturing sites that can meet today’s demand, support future launches, and strengthen our production footprint while continuing to invest in the people who make it all possible.”
