General Motors has been keeping most details under wraps, but U.S. buyers should expect to see the 2011 Buick Regal being offered with a variety of 4-cylinder turbocharged petrol engines as well as a larger-displacement and smoother in operation V6 that can be combined with all-wheel drive.
The recent introduction of the Opel Insignia OPC that packs an all-wheel drive system and a 325HP turbocharged V6 also leaves the door open for a sporty version of the Buick Regal in the future that could revive the GNX nameplate.
