For years Buick built cars that appealed mainly to an older buying audience. While it's worked hard to shed that image in the post-bankruptcy GM world (mainly with rebadged Opels), the task still isn't fully complete. But a new report coming from Bloomberg hints that's all about to end tomorrow at the 2016 Detroit Auto Show. Supposedly, Buick will reveal a brand new coupe concept that'll be based on the same rear-wheel-drive platform as the Chevrolet Camaro and Cadillac ATS.

What's under the hood is still a bit of a mystery but we wouldn't at all be surprised to see a twin-turbo V6 lurking in there. Best yet, this concept is said to be nearly production ready. Now, is this the return of the much beloved Grand National, a different nameplate from Buick's past, or something new entirely? We'll have answer first thing tomorrow from the showroom hall of COBO Center. Stay tuned.
