The General giveth and The General Taketh Away. The 2014 Buick Regal Turbo and Regal GS will now get all-wheel drive as an option, with the ability to send up to 90 percent of the engine’s power to the rear wheels. But both the Turbo and the GS will get the same engine, a 259 horsepower, 295 lb-ft 2.0T 4-cylinder. Only the GS model will get a 6-speed manual.
