Highlights from the Buick press release:

The all-new, 2012 Regal GS blends a 270-horsepower (201 kW) high-output Ecotec 2.0L turbo engine, six-speed manual transmission, responsive Interactive Drive Control System suspension technology with exclusive GS-mode, Brembo front calipers and other features into one of Buicks most balanced performance sedans ever.

The torque from Regal GSs exclusive Ecotec 2.0L high-output turbocharged engine provides more launch force than the Acura TSX V-6, Audi A4 Sport, Lexus IS 250 and 350, Infiniti G25 and G37, and Volvo S60. It also delivers the highest specific output of any production engine GM has ever offered, and at 135 horsepower per liter, is the most power-dense engine ever certified by the Society of Automotive Engineers.

Buicks exclusive Interactive Drive Control System is standard on the Regal GS, and allows drivers to choose from three operating modes “ Standard, Sport and GS Mode “ that change the suspension settings and steering sensitivity according to driver preferences. Regal GS also features a four-wheel independent suspension with a unique High Performance Strut (HiPer Strut) front suspension design that reduces torque steer and improves grip and cornering power.

A lower ride height, 19-inch, 5-Twin Spoke alloy wheels (20-inch, 5-Twin Spoke polished alloy wheels with summer-rated performance tires are available) and four-piston Brembo front calipers also contribute to the GS performance persona.
