When and if the Buick Regal GS makes it to market, we're not going to see a 325-hp turbocharged 2.8-liter V6 under the hood. Rumors that the Regal GS would get such a motor started almost immediately after the Regal was unveiled, with the Opel Insignia on which it's based offering that very powerplant and GM announcing a high-performance GS model was in the works. Those rumors seemed to come true when the Regal GS Show Car, unveiled at the Detroit Auto Show, had that very same turbo V6.
Yet, despite what was there, GM said the Regal Show car had a high-boost version of the turbocharged 2.0-liter Ecotec 4-cylinder found in the CXL model. Instead of 220-hp an 258 ft-lbs f torque, however, the GS has 255-hp and 295 ft-lbs of torque, ensuring a 0-60 mph time of roughly 6.0 seconds.
According to Buick/GMC General Manager Brian Sweeney in a conversation on GM's Fastlane blog, the 325-hp motor is not in the plans. "At 255hp with 0-60 in less than 6 seconds we think we're in good shape if we bring this to production."
Buick has yet to confirm a production model GS, but at this point it's essentially a done deal.
