2011 Buick REGAL LS Loaded

General Motors Co.'s Buick division released images and information for the 2011 Buick Regal and is openly billing the new-age Buick as a sport sedan.Given the new Regal's origins with GM's second-generation global midsize chassis that was engineered by Adam Opel AG - the Germany-based European division GM just retrieved from the clutches of mega-supplier Magna and Russia's Sberbank - there might be reasonable credibility for the sport-sedan claim.In addition to being based on the German-engineered Epsilon II architecture also used by the well-regarded new Opel Insignia (not to mention Buick's new LaCrosse sedan), the 2011 Regal also will be built in Germany at Opel's Russelsheim assembly plant.The Regal's lines may be some of the crispest ever to be seen in a Buick showroom and GM is calling out the Acura TSX, Volkswagen Passat, Mazda6 and even the Volvo S60 as competitors. The Regal goes on sale in the second quarter next year - and in a significant sign of the times, only 4-cylinder power will be on offer.
