2012 BUICK REGAL GS PRODUCTION MODEL TAKES SPORTS SEDAN PERFORMANCE TO A NEW LEVEL FOR BUICK
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 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).
Inside is a racing-inspired, flat-bottom sport steering wheel and metal sport pedals, along with leather-appointed 12-way power-adjustable sport 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

• 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 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). 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 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.
'We've been combining direct injection and variable valve timing with boosted 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.

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 varied road 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.Source - Buick
REGAL GS SEEKS REPEAT PERFORMANCE IN OPEN ROAD RALLY
The 2012 Buick Regal GS sport sedan, along with two Buick engineers, will compete in the Nevada Open Road Challenge on May 20 seeking to repeat a class victory in the event.
In September 2011, GS lead development engineer Bill Rietow with GS powertrain engineer John Townsend as his navigator won the 120-mph class of the Silver State Classic Challenge, which takes place on the same open road course. The team also won a 'Most Accurate Rookie' award with a 0.019-second deviation from the perfect 45-minute time to complete the course.
'We learned a lot about the intricacies of the course on our first time out' said Rietow. 'We now know that the segment known as 'the Narrows' can be safely negotiated at 90 mph. By planning the slow down into and the acceleration rate out of the Narrows, we can more accurately control our pace to the target average speed. At times, we'll need to run at the GS's top speed.'
In this month's race, the Regal GS will compete against world class sports cars in the more difficult 135-mph class.
'The competition in this class was really good last fall and we look forward to competing,' said Townsend. 'Weather is going to be an interesting factor this time around, with headwinds as high as 20 mph possible.'
The Nevada Open Road Challenge, like the September event, takes place on a remote, two-lane, 90-mile-long segment of Nevada State Highway 318. Rather than a test of who finishes a course the fastest, the goal is average speed consistency. In the Regal's class, the team that averages closest to 135 mph over the entire course wins. In many instances, the top three finishers are just hundredths of seconds off the target time.
The Regal GS being piloted by Rietow and Townsend is a stock 2012 model, with modifications limited to safety equipment such as a roll hoop and five-point harness seat belts, as well as data collection computers.
'This is another great opportunity to showcase the GS and its comfort and capability at real-world condition high speeds,' Rietow §äid. 'Stability, body control and durability are all being tested to extremes. Events like these provide safe conditions for us to get away from the test track to gather unique data that will benefit future development of our vehicles.'Source - Buick
