Ask and you shall receive – well, almost. While GM listened to us when we asked for a Buick version of the Opel Insignia OPC ever since the Regal sedan made its debut last year, the company kind of ignored us in terms of performance. Yes, while the Buick Regal GS Concept looks like every bit of Insignia OPC, under the hood, it’s a completely different car.

Unlike the Opel Insignia OPC, which is powered by a 325-hp 2.8L V6 turbo, the Regal GS Concept rolls into Detroit with a 2.0L Ecotec turbocharged 4-cylinder making 260-hp. That’s just 40 more horses than the top-of-the-line Regal without the GS badge. With that in mind, the all-wheel-drive Buick Regal GS seems to compete with entry level luxury sedans like the Acura TL, Audi A4 and the Lexus IS to name a few.

Either way, GM isn’t saying anything about a production version right now, but we wouldn’t discount the possibility even a little. Stay tuned to see what Buick will offer.
