Rumors surrounding the possibility of a Buick Regal Wagon are starting to firm up. Now rumors of a performance variant of said wagon wearing a “GS” badge are starting to surface. According to Automotive News a GS version is the alleged wagon is likely.

Supplier documents and dealership meetings have confirmed rumors of the existence of a Regal Wagon. According to the report, the dealership meeting also included photos of a GS version of the Regal Wagon. Without actual photos to report, this is about as much of a confirmation as we can get.

The idea of a GS version of the Regal Wagon is not all that far-fetched. The new one is expected to be imported from GM’s Rüsselsheim, Germany assembly plant that builds the Regal’s sister-car, the Opel Insignia. Opel will unquestionably have a performance OPC model of the Insignia Wagon, so slapping Buick and GS badges on it doesn’t seem too difficult.

Exact details of the Insignia OPC and Regal GS have been scarce. Recent spy shot videos of the Insignia OPC strongly indicate that power will come from a turbocharged V-6, of which GM has several possibilities to utilize. Insiders have also said to expect six-speed manual and eight-speed automatic transmission options with the performance versions.

One report suggested the OPC and GS would achieve over 400 horsepower and funnel that power through the latest dual-clutch Haldex all-wheel drive system. If true, that will certainly silence critics of the current four-cylinder-powered Regal GS.
