GM's Camaro platform spawns Buick's first rear-drive sedan in decades
GM plans a Buick rear-drive sedan built on the next-generation Camaro platform, produced at Lansing Grand River starting fall 2027 alongside a CT5 replacement and the Camaro, with Alpha 2-2 underpinnings and a likely turbo/hybrid mix (and possible V8/manual). Annual volumes are expected to be modest, signaling Buick's return to RWD performance sedans after 30 years.
