With the North American International Auto Show just around the corner, Buick has released new information about the Regal GS show car.

Essentially a rebadged Opel Insignia OPC (except the powertrain), the GS features a revised front end, a reduced ride height, unique rocker panels, an integrated rear spoiler, dual exhaust pipes, and 20-inch wheels outfitted with high performance tires. Inside, Buick added a sport steering wheel, metal pedals, and Recaro front seats.

Power comes from a turbocharged 2.0-liter Ecotec engine, that produces 255 hp (190 kW) and 295 lb-ft (400 Nm) of torque. Connected to a six-speed manual transmission and an adaptive all-wheel-drive system (with an electronic limited-slip rear differential), the GS can accelerate from 0 to 60 mph in less than 6 seconds. Other goodies include an Interactive Drive Control System (IDCS) and a Brembo braking system.

According to Buick's product marketing manager, Craig Bierley, "We designed the Regal GS to explore the appeal of a high-performance variant of the Regal." While it's not a confirmation that the GS will go into production, it sounds like GM is considering the possibility.

Opel's Insignia OPC is powered by a 2.8 liter V6 single, twin-scroll turbocharged ECOTEC engine with 325 hp while the same 2.0-liter turbo ecotec engine in the Opel makes 162 kW (220 PS; 217 hp).
