During our preview this morning of upcoming products from both Buick and GMC, we learned that the Buick lineup will expand its lineup to include six models within the next 24 months. Joining the LaCrosse and Enclave (it sounds like the Lucerne is on its way out) will be two new sedans and two new crossovers.

One new four-door will be a mid-size sedan based on the Opel Insignia and possibly wear the Regal nameplate. The other will be a smaller, entry level compact sedan based on the new Opel Astra. We also saw a teaser last week of the new compact crossover for Buick that's basically a rebadged Saturn Vue. An even smaller CUV based on the Delta platform will also be added.

Over at GMC, a Denali version of the Acadia will likely be added along with another small CUV that could be a competitor for the upcoming mini countryman.
