New or Significantly Altered Models

2011 Buick Regal
One of Buick's most storied nameplates returns on a new mid-sized front-wheel-drive sedan. The Regal is derived from the Opel Insignia sold in other markets. Two four-cylinder engines are planned for the first model year. The 2.4l four cylinder will be offered first, with the optional turbocharged four-cylinder later in 2010. Only a CXL trim level is planned for 2010, with more to be added in 2011.

Mostly Unchanged

2011 Buick Enclave
2011 Buick LaCrosse
The 2.4l four cylinder becomes the standard engine in CX and CXL FWD models. The 3.0l six cylinder is discontinued.
