2012 Buick Regal GS revealed

GM has revealed the 2012 Buick Regal GS during the weekend, through a series of photos and extensive details ahead of its market launch scheduled for 2011.

Compared to the regular Buick Regal, the GS model comes with a more aggressively styled front end, new 19 inch alloys, trapezoidal exhaust tips and a lower ride height due to the new Interactive Drive Control System which also allows adjustment of the steering sensitivity.

At the interior the 2012 Buick Regal GS features sport seats, a sport steering wheel, aluminium pedals, a premium sound system and Bluetooth connectivity.

In terms of performance the 2012 Buick Regal GS which uses a turbocharged 2.0-litre 4-cylinder engine producing 255 HP and 400 Nm (295 lb-ft) of torque can sprint from 0 to 60 mph in less than 7.0 seconds while top speed was not specified.

The 2012 Buick Regal GS price will be announced sometime net year, and for more official details you check out the press release below.

MIAMI – Buick this evening reveals the production

version of the 2012 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). Buick’s Interactive Drive Control System is standard on the GS, allowing drivers to customize the driving experience by changing the suspension settings and steering sensitivity between three modes: standard, sport and GS.

“Built on the performance foundation of the Regal, the Regal GS was designed as an even sportier expression of responsive performance and style,” said John Schwegman, vice president of Buick marketing. “The driving experience is powerful and spirited; and the GS represents the next entry in Buick’s product renaissance.” 

The Regal GS will be unveiled this evening at a consumer event in Miami. It goes on sale in the second half of 2011. Pricing has not yet been announced.

Product highlights include:

  • Exclusive Ecotec 2.0L turbocharged and intercooled engine rated at an estimated 255 horsepower (190 kW) and 295 lb-ft of torque (400 Nm)
  • Six-speed manual transmission, with six-speed automatic with Driver Shift Control to be offered later
  • Interactive Drive Control System with GS mode
  • Four-wheel independent system with HiPerStrut front suspension
  • High-performance four-wheel disc brake system with Brembo front calipers
  • Standard 19-inch, 5-Twin Spoke alloy wheels and all-season tire and optional 20-inch, 5-Twin Spoke polished alloy wheels with performance tires.

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 GS cuts asportier 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).

Inside is a racing-inspired, flat-bottom sport steering wheel and metal sport pedals, along with leather-appointed 12-way power-adjustablesport driver and front passenger heated seats, which include four-way power lumbar. The GS-specific black interior is accented with satin-finish elements on the instrument panel, steering wheel and console, while the instrument panel glows white when the driver engages the GS mode of the Interactive Drive Control System (IDCS).

Standard amenities for the Regal GS include:

  • Passive keyless entry with push-button start
  • Standard XM Satellite Radio with three-month trial service
  • Harmon/Kardon premium 320-watt sound system with nine speakers
  • Bluetooth phone connectivity
  • Leather-wrapped flat-bottom steering wheel with audio controls
  • Leather-appointed sport seating
  • Heated driver and front passenger seats, with 12-way adjustable driver and front passenger seats – including four-way lumbar adjustment
  • 120-volt accessory power outlet
  • Power windows with express up/down feature in the front and express down in the rear.
  • Front and rear ultrasonic parking assist
  • Bi-xenon HID headlamps.

Turbocharging and HiPerStrut

Power for the Regal GS comes from a high-output version of the Ecotec2.0L 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 boostpressure in the GS. The output is rated at 255 horsepower (190 kW) and 295 lb.-ft. of torque (400 Nm). A three-inch-diameter exhaust system provides reduced back pressure, resulting in higher engine power

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 emissionsgenerated – including a 25-percent drop in cold-start hydrocarbon emissions. Variable valve timing optimizes power, efficiency and emissions across the entire rpm band.

“We’ve been combining direct injection and variable valve timing withboosted engines since 2006, and there’s no question the Regal GS turbo has the responsiveness and acceleration of a 3.5L V6, while delivering the fuel economy of a 2.0L four,” said Mike Anderson, Ecotec global chief engineer and program manager.

The engine is mated to a standard six-speed manual transmission. A six-speed automatic transmission will be available later.

The 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 HiPerStrut system helps reduce torque steer and maintain negative camber during cornering; the driver experiences reduced torque steer, improved grip and increased cornering power, along with crisper handling, steering precision and feedback.

The four-link independent rear suspension is designed to minimize unwanted toe and camber effects during spirited driving maneuvers, enhancing vehicle stability.  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. More aggressive, performance-oriented damping characteristics can also be selected by the driver through the Interactive Driver Control System.

Braking power comes from a large diameter four-wheel disc brake system featuring Brembo front calipers. A standard, four-channel anti-lock brake system is tuned to reduce stopping distances over variedroad surfaces and conditions.  An electronic parking brake is actuated via a center console-mounted control. The Regal GS also features standard StabiliTrak stability control system with integrated, full-function traction control.

Interactive Drive Control System

The 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.

A sophisticated driving mode control module continually monitors driving style utilizing yaw rate, lateral and longitudinal acceleration,steering wheel, throttle and vehicle speed. It defines the dynamic vehicle state, including acceleration, braking and cornering, to optimize chassis reactions. It also executes all of the IDCS driver selections. All four dampers are electronically controlled and continuously adapt within milliseconds to the prevailing road conditions, vehicle movements and individual driving style.

Selecting GS mode optimizes the car for dynamic driving, tightening the suspension and steering response. “Standard,” or the default mode, is the setting for all-around use. The sport mode provides a level of performance between standard and the GS modes.
