Aside from that, a close look reveals subtle changes along the lower edge of the car. The fenders seem to be slightly flared. They're complemented by sideskirts that are rounder and chunkier than that of the normal Insignia wagon. These styling touches also suggest that this Buick variant will take on the psuedo-crossover aesthetic with black plastic body cladding.
If this is the case, the Buick Regal wagon could be the high-riding, plastic-clad Regal TourX that's been rumored. We know that General Motors trademarked the TourX name a while back, and Buick wants more crossovers or crossover-esque vehicles since they make up the majority of the brand's sales. It would also be an excellent option to established models such as the Audi A4 Allroad, Volvo V60 Cross Country, and Subaru Outback. Considering the fact that we've seen the Opel Insignia and Holden Commodore revealed already, we expect the Buick versions to be fully revealed sometime this year.
