SPRING HILL, TN—General Motors has begun producing the Cadillac LYRIQ sport utility vehicle at its assembly plant here. The 32-year-old manufacturing complex, formerly the home of Saturn, is GM’s largest facility in North America.

Spring Hill Assembly is one of five plants that GM has earmarked to mass-produce EVs in North America, along with Factory ZERO in Detroit, Orion Assembly in Michigan, CAMI in Canada and Ramos Arizpe Assembly in Mexico.

“The Cadillac LYRIQ sets the standard for the future of Cadillac and marks another major milestone in [our] commitment to an all-electric future,” says Mark Reuss, president of General Motors. “This is a monumental day for the entire GM team. We retooled Spring Hill Assembly with the best, most advanced technology in the world and the team worked tirelessly to complete the preparations nine months ahead of the original schedule.”

The Cadillac LYRIQ, the brand’s first all-electric vehicle, is built on GM’s Ultium platform, the heart of the company’s EV strategy. The Ultium platform encompasses a common electric vehicle architecture and propulsion components like battery cells, modules, packs, drive units, traction motors and integrated power electronics.

“Through the Ultium platform, [we] will realize a strategic value chain shift across [our] network of vehicle assembly plants as the company commonizes and streamlines machinery, tooling and assembly processes,” explains Reuss. “This flexibility enables lower capital investments and greater efficiencies as additional assembly plant transformations occur.”
