Expected to be launched in 2010 (as a 2011 model), the Regal will slot below the Buick LaCrosse.

GM has officially confirmed, one of the worst keep secrets in the industry, the Buick Regal will return to the lineup.

While the company didn't provide any useful information, the Regal will undoubtedly be a rebadged Opel/Vauxhall Insignia. This effectively means the US Buick Regal will be virtually identical to the Chinese version (pictured).

Engine options will likely include a 2.0-liter turbocharged four-cylinder with 217 hp, a 2.8-liter turbocharged V6 with 256 PS, and possibly the 325 hp 2.8-liter turbocharged V6 from the Insignia OPC/VXR.

Expected to be launched in 2010 (as a 2011 model), the Regal will slot below the Buick LaCrosse.

Look for more information to be released in the coming months.
