The Buick Regal GS Concept was introduced at the 2010 North American International Auto Show and comes with an estimated 255 turbocharged horsepower (190 kW), a six-speed manual transmission and an advanced, adaptive all-wheel-drive system. Exterior and interior cues include two additional vertical front air intakes; large, forged aluminum 20-inch wheels and performance tires; a racing-inspired sport steering wheel and metal pedals. Recaro high-performance front seats feature four-way lumbar support and cushion extensions.
Power for the Buick Regal GS comes from a high-output 2.0L Ecotec turbocharged engine with direct-injection technology. It is based on the engine that will be offered on Regal CXL models later this summer, but the engine and turbocharger are tuned to deliver greater boost pressure in the GS. The output is estimated at 255 horsepower (190 kW) and 295 lb.-ft. of torque (400 Nm). The engine is mated to a six-speed manual transmission that directs torque to an adaptive all-wheel-drive system calibrated for performance driving. The high-performance drivetrain is expected to enable the Buick Regal GS to accelerate from 0 to 60 mph in less than 6 seconds.
The Buick 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. The Buick 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).
