Buick revealed today ahead of the Detroit Auto Show, the brand new Regal GS Concept, a high-performance version of the brand's newest sport sedan. The new car is based on the Opel Insignia OPC and carries a 2.0L Ecotec turbocharged engine with direct-injection technology capable to deliver 255 horsepower (190 kW) and 295 lb.-ft. of torque (400 Nm).
It is based on the engine that will be offered on Regal CXL models later this summer, although we don't understand why GM didn't install the 2.8-liter turbocharged unit that produces 325 hp (242kW).
The engine is mated to a 6-speed manual transmission that directs torque to an adaptive all-wheel-drive system calibrated for performance driving.
The car can sprint from 0 to 60 mph in less than 6 seconds and is helped to achieve this by the four-wheel-independent suspension, with a unique High Performance Strut (HiPerStrut) design in front.
This HiPerStrut system helps reduce torque steer and maintain negative camber during cornering. In order to stop the car safely, the new Regal GS features a high-performance Brembo brake system with 14 x 1.2-inch (355 x 32 mm) cross-drilled rotors; four-piston, high-strength aluminum calipers, and high-performance pads.
Regal GS is also equipped with Interactive Drive Control System (IDCS) chassis technology (also offered on Regal CXL models with the 2.0L turbo engine).
Inside, the car features a completely jet black interior, including the pillars and headliner, sport shifter for the six-speed manual transmission and a suede-covered, flat-bottom steering wheel reminiscent of those used in international racing series.
The instrument panel features an interesting system that glows ice blue when the driver engages the sport mode of the Interactive Drive Control System (IDCS).
