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 Buick’s most balanced performance sedans ever.
The torque from Regal GS’s 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.
Buick’s 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.

Drivers may choose more aggressive, performance-oriented damping characteristics through the standard Interactive Drive Control System.
- Four-wheel-independent suspension, with a unique HiPer Strut front suspension design.
- Ride height lowered 10 mm, and spring and stabilizer bar rates raised by 20 percent for more responsive handling.
- HiPer Strut system helps reduce torque steer, improve grip and maintain negative camber during cornering.
- Four-link independent rear suspension is designed to minimize unwanted toe and camber effects.
- Both front and rear dampers incorporate active Computer Damping Control (CDC), continuously changing damper characteristics’ to maintain optimal vehicle ride control over varying road surfaces and profiles.
- Four-wheel disc brake system with Brembo four-piston front calipers, larger ventilated front discs and high performance linings.
- Electronic parking brake actuated via a center console-mounted control.
- Standard StabiliTrak stability control system with integrated, full-function traction control.
Interactive Drive Control System
The Regal GS is equipped with the Interactive Drive Control System, which adapts damping and other driving functions to drivers’ preferences. While the Regal Turbo offers Interactive Drive Control with the choice of a standard adaptive setting, a more comfortable Tour mode and a Sport mode, the system in the Regal GS is deliberately tuned for those who enjoy a higher level of performance:
- Standard: Delivers ideal all-round performance, while maintaining comfort characteristics for everyday driving.
- Sport: Features a firmer level of suspension damping and reduces body roll for more agility.
- GS: Readies the car for dynamic, enthusiast-level driving. Increased steering efforts provide more direct feedback to the driver, while increased damping levels ensure ultimate wheel control and reduced body roll for ultimate agility. Only the GS mode will alter the shift feel on an automatic transmission.
