Buick this evening reveals the production version of the 2012 Buick Regal GS, an even sportier expression of the Regal sport sedan that went on sale earlier this year and has attracted new buyers to the Buick family. Powered by a high-output, exclusive Ecotec 2.0L turbocharged engine mated to a six-speed manual transmission, the GS delivers an estimated 255 horsepower (190 kW) and 295 lb.-ft. of torque for a 0-60 mph performance of less than seven seconds (estimated).
The exterior design features unique front and rear fascias, with the front fascia incorporating prominent, vertical air intake slots and specific grille treatment – with the vertical elements accented in a satin-metallic finish. The rear fascia has a pair of integrated, satin-metallic trapezoidal exhaust outlets. Rocker panel extensions and an integrated rear spoiler are also woven into the design. The Buick Regal GS cuts a sportier stance, too, with a slightly lower ride height than other models and aggressive 19-inch, 5-Twin Spoke alloy wheels and all-season tires (20-inch, 5-Twin Spoke polished alloy wheels with performance tires are optional).
Power for the Buick Regal GS comes from a high-output version of the Ecotec 2.0L turbocharged DOHC VVT engine with direct injection technology. It is based on the engine that will be available on Regal CXL later this year, but the engine and turbocharger are tuned to deliver greater boost pressure in the GS. The output is rated at 255 horsepower (190 kW) and 295 lb.-ft. of torque (400 Nm).
Direct injection technology helps the engine deliver more power through increased efficiency, while maintaining fuel economy and lowering emissions. That means less fuel is consumed and lower emissions generated – including a 25-percent drop in cold-start hydrocarbon emissions. Variable valve timing optimizes power, efficiency and emissions across the entire rpm band.
The Buick Regal GS rides on a relatively long wheelbase of 107.8 inches (2738 mm), which delivers refined, well-balanced vehicle dynamics. It also features a four-wheel-independent suspension, with a unique High Performance Strut (HiPerStrut) front suspension design.
The Buick Regal GS is also equipped with Interactive Drive Control System (IDCS) chassis technology (also offered on other Regal models with the 2.0L turbo engine). It delivers enhanced vehicle stability and greater driving safety. The driver selects among three operating modes – standard, sport and GS – that change the suspension settings, and steering sensitivity through the variable-effort steering system. [Source: GM]
