2011 The Buick Regal

Like so many European vehicles, the Insignia has numerous engine choices, nine to be exact. Gas and diesel engines ranging from 1.6L I4 to a 2.8L turbo-charged V6 are available. Likely, a larger in-line four and one or two V6 powered engines will be offered with the Insignia. Unfortunately, no diesel option will be available, given the cost of meeting stringent US pollution requirements.

GM has revealed the production version of the 2010 Detroit Auto Show's Buick Regal GS concept but to our disappointment, the automaker has kept the 255HP 2.0-liter turbocharged engine instead of the Opel Insignia OPC's far more potent 2.8-liter twin-scroll turbocharged V6 with 325 ponies. The General's cost-cutters also ditched the OPC's four-wheel drive system as the GS is a front-wheel drive model only.
