At the 2010 North American International Auto Show in Detroit, Buick is introducing the Buick Regal GS show car, a high-performance version of the brand's recently debuted sport sedan. The GS version benefits from a turbocharged engine unit capable to deliver 255 turbocharged horsepower (190 kW), a six-speed manual transmission and an advanced, adaptive all-wheel-drive system.

Developed to provide the most enjoyable sporting driving experience, the new Regal GS gets specially engineered mechanical elements. It boasts a performance-enhanced drivetrain, a lowered body and lower center of gravity.

Outside, the vehicle's sportier stance is distinguished by two additional vertical front air intakes, unique rocker panels, integrated rear spoiler, dual exhaust outlets and a set of huge, forged aluminum 20-inch wheels wrapped in performance tires.

The GS interior also includes few sporty features - racing-inspired sport steering wheel, sport shifter, metal pedals and Recaro high-performance front seats with four-way lumbar support and cushion extensions. The instrument panel glows ice blue when the driver engages the sport mode of the Interactive Drive Control System (IDCS).

"We designed the Regal GS to explore the appeal of a high-performance variant of the Regal," said Craig Bierley, product marketing director for Buick. "Like the Regal, the Regal GS is based on the award-winning Opel Insignia, and we believe it will reinvigorate Buick's storied Gran Sport legacy."

The sporty Regal's output performance is achieved through a turbocharged 2.0L Ecotec engine with direct-injection technology. Based on the engine scheduled for the Regal CXL models, the newcomer's power unit is tuned to deliver greater boost pressure. The output is estimated at 255 horsepower (190 kW) and 295 lb.-ft. of torque (400 Nm).

Among the other highlights featured in the new Regal GS are an electronic limited-slip rear differential, four-wheel-independent suspension, HiPerStrut system, high-performance Brembo brake system and an Interactive Drive Control System (IDCS).
