One of the eye catching displays over at GM is the Buick Regal GS. The Regal is basically the European Opel/Vauxhall Insignia rebadged as a Buick for the US and Chinese market (Buick is a highly regarded marque in China). This GS showcar features a potent performance package – 255 bhp/400 Nm 2.0-litre Ecotec turbo engine with power going to all wheels via a six-speed manual gearbox and electronic LSD.

Acceleration from nought to 60 mph (96 km/h) is “less than six seconds”. The Vauxhall Insignia VXR, which has a 320 bhp 2.8-litre Ecotec V6 turbo does the same sprint in 5.8 seconds. The Regal GS features a lowered body and aggresive styling that mimics the VXR, except that it wears Buick’s signature “waterfall grille”. The show car wears 20-inch wheels.

That front HiPerStrut suspension helps reduce torque steer and maintain negative camber during cornering, improving grip and feel while isolating undesirable feedback. The GS features Brembo brakes with cross-drilled rotors, four-piston aluminum calipers and uprated pads. Interactive Drive Control System (IDCS) chassis technology allows the selection of three modes – normal, sport and GS – that change suspension settings, throttle response and steering sensitivity.

Inside, the Regal GS features a full black interior, sport shifter, a suede-covered, flat-bottom steering wheel and Recaro seats with four-way lumbar support and cushion extensions.
