As you may know already, the current Buick Regal is in fact a rebadged version of the Opel Insignia, which was designed for the European market. The Regal badge returned to the Buick lineup back in 2010, after a six-year break, and it is currently being assembled at GM’s Oshawa, Ontario, plant. Same plant is used by GM to build the Chevrolet Camaro, Cadillac XTS as well as the Chevrolet Impala.
Still, it appears that this plant doesn’t have a bright future ahead as GM already announced that the next-generation Camaro will be built at Lansing, Michigan while its Detroit-Hamtramck plant already builds the Chevrolet Impala.
The Cadillac XTS is a low volume vehicle and the production could be shifted to Detroit-Hamtramck plant too. Regarding the Regal, a redesign is planned for mid-2017, after the Opel Insignia gets a new generation.
Moreover, General Motors announced that by 2017, its plant located in Russelsheim, Germany, will build a new model which will be sold in the United States under the Buick brand name.
Same plant builds the Opel Insignia and we wouldn’t be surprised if General Motors will choose to build the next-generation Buick Regal in Germany and export it to the United States. Of course, an Opel spokesman declined to make any comments.
