Buick has announced that it’s bringing a high(er)-performance GS version of its Opel Insignia-based Buick Regal to the Detroit Auto Show, and later, to the US market. And for once we’re left wishing we were getting a rebadge. After all, for the first several years of US sales, Insignias will be imported from Germany, meaning GM could easily have brought the thoroughly mad Insignia VXR/OPC as a quick-and-dirty (if not cheap) rebadge. After all, the point of the Regal (and especially the GS) is that “we’re trying to rebuild the performance credentials that Buick once held,” as GM reps put it. The European OPC/VXR version gets a 325 HP version of the turbocharged V6 found in the SRX and Saab TurboX, while the GS gets only a 255 hp version of the 2.0 Turbo found in the Solstice GXP. That engine can reportedly be tuned to an easy 310 hp and 300 lb-ft of torque, making the “base” Regal CXL with the 220 hp 2.0T engine a much smarter buy. Unless the idea of tuning a Buick is simply more cognitive dissonance than you can handle. Otherwise, the only thing the GS really brings to the table is AWD and a bodykit with more front-end venting than the United States Senate. Still, if you’re young enough to not get a discount at Denny’s and you have to own a Buick, the Regal is the way to go… especially once an enterprising tuner starts offering Opel badging and grilles in the US market.
