Buick hasn’t had a sedan on sale in the U.S. since the LaCrosse and Regal were discontinued. Now an SUV-only marque, it’s a disappointing gap in its lineup after decades of classy and comfortable Buick sedans. But this could change in the not-too-distant future, as General Motors is rumored to be exploring the possibility of a new Buick sedan. This new model could potentially share a platform with another new sedan in the General Motors portfolio—the upcoming Cadillac CT5.

Buick’s Potential Sedan Comeback
Buick
According to GM Authority sources, GM is considering adding new passenger cars for the U.S. market, and a new sedan is one possibility. It could be derived from the Alpha 2 architecture expected to underpin the next-generation Cadillac CT5. That suggests the new Buick could be a compact or midsize sedan; these promise to be more successful than a large sedan. Outside of the Germans, full-size sedans have lost significant traction in this market.
American brands have largely abandoned the sedan segment, with Lincoln, Ford, and Chrysler all not having a single sedan in their existing lineups. Dodge still has the four-door Charger and Cadillac’s current CT5 is still around for now, but these are the only models keeping the American sedan alive. That’s if you exclude EV-only brands like Lucid and Tesla, which both sell sedans.
Buick
In other regions, Buick’s current design language works well on a modern sedan. The sleek Electra L7 sold in China is one example. Built in collaboration with China’s SAIC, it’s an alternative to premium sedans from rivals like BYD.
If Buick does bring back a sedan, it won’t be the only premium/luxury brand to do so. Infiniti, also reduced to an SUV-only lineup, will be releasing a new Q50, expected in 2027. That will be a sporty V6-powered model, but a new Buick sedan would likely be more Lexus-esque in its execution, where comfort and refinement are top priorities.

What It Means
Buick
General Motors has not confirmed that a new Buick sedan is coming, so the rumors should be taken with a pinch of salt. If it does happen, such a car could help Buick build upon its reputation for affordable luxury. The confirmation that a new Cadillac CT5 is on the way also increases the odds of a Buick sedan comeback, as Buick wouldn’t need to develop a new platform from scratch, so development costs can be saved. After 2025 sales that were its best in years, a more diverse lineup that includes a sedan can further boost Buick’s fortunes in the years ahead.
