Cadillac CT4 Production Ends as GM Retires Compact Luxury Sedan

Cadillac has officially brought Cadillac CT4 production to a close, ending the lifecycle of its compact luxury sedan at the General Motors Lansing Grand River Assembly plant in Michigan, United States. Manufacturing concluded on June 25, marking the retirement of the CT4 lineup, including the performance-focused CT4-V and CT4-V Blackwing variants. The model leaves the brand's portfolio without a direct successor, signaling a shift in GM's product strategy as the company prepares the Lansing facility for a new generation of rear-wheel-drive vehicles built on an updated platform.

Final Orders Closed Before Production End

Retail ordering for the Cadillac CT4 officially ended on April 20, 2026, several weeks before assembly operations concluded. With production now complete, the Lansing Grand River Assembly plant continues manufacturing only the larger Cadillac CT5 until future vehicle programs begin. The discontinuation of the CT4 reduces Cadillac's sedan portfolio and concludes the production run of a model that served as the brand's entry point into the compact luxury sedan segment.

Lansing Plant Preparing for Future Vehicle Programs

According to recent reports, the Lansing Grand River Assembly facility will transition to manufacturing several new rear-wheel-drive products. Planned vehicles include the next-generation Cadillac CT5, an all-new Buick sedan, and the successor to the Chevrolet Camaro. The Camaro replacement is expected to be offered in either a two-door or four-door configuration, expanding GM's future performance-oriented lineup while maintaining a rear-wheel-drive foundation for these upcoming models.

Updated Alpha 2-2 Platform to Support New Models

Future vehicles scheduled for production at Lansing are expected to utilize GM's updated Alpha 2-2 architecture. This platform will continue supporting an internal combustion engine-based, rear-wheel-drive layout, providing the structural foundation for the next generation of Cadillac, Buick, and Chevrolet products manufactured at the facility. The updated architecture is intended to carry forward the performance and driving characteristics associated with GM's rear-wheel-drive vehicle lineup.

Cadillac CT4 Legacy

The Cadillac CT4 entered the market in 2019 as a 2020 model-year vehicle, replacing the Cadillac ATS, which had previously been available in both coupe and sedan body styles. Built on GM's Alpha platform, the CT4 shared its rear-wheel-drive architecture with the current Cadillac CT5 and the discontinued sixth-generation Chevrolet Camaro. Its production run established the model as Cadillac's compact luxury sedan before the company shifted its manufacturing priorities toward future rear-wheel-drive products.
