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.

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).

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.

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 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.

Armed with turbocharged horsepower, a driver-selectable suspension system and a firm, European-tuned chassis, the all-new Buick Regal delivers a driving experience that rivals the best import sport sedans in the segment.

“The 2011 Buick Regal is like nothing you’ve ever experienced from this brand,” said Roger McCormack, director of product marketing for Buick. “The Regal is the next chapter in Buick’s transformation and will expand the portfolio to include a modern sport sedan.”

The new Regal takes on competitors such as the Acura TSX and Volvo S60. It has a longer wheelbase and greater trunk volume than those vehicles, along with standard features – including a six-speed automatic transmission, 18-inch alloy wheels and OnStar – that aren’t offered standard on either competitor. And with an estimated 30 mpg on the highway, it delivers excellent fuel economy, too.

The Regal’s development is rooted in Germany, where the globally led engineering team created the award-winning Opel Insignia – the 2009 European Car of the Year. The Insignia has garnered more than 31 prestigious awards and is the best-selling midsize sedan in Europe. Regal will bring all of Insignia’s award-winning design, technology and European-inspired performance capabilities to the American market.

Design story

The Regal’s sleek body design blends the sweeping silhouette and proportions of a coupe in a progressive package that suggests motion from all angles. Great attention to detail complements that aggressive styling, with tailored applications of Buick’s signature design cues, such as the waterfall grille, select use of chrome trim and superior fit and finish of the exterior panels.

“Regal is all about great proportions,” said John Cafaro, design director, passenger car. “For example, the fenders are flared to wrap around the tires, an aggressive stance that people aren’t used to seeing in recent Buicks.”

The car’s performance-oriented spirit is also conveyed in sleek, sculpted body-side detail and aggressive headlamps that further suggest motion. At the rear, an abbreviated deck and tucked-in body panels are the hallmarks of a contemporary sport sedan, with bold taillamps and their intricate lighting elements reinforcing Regal’s attention to detail. Eighteen-inch alloy wheels are standard.

The sweeping design motif carries over to the interior, where the side panels flow uninterrupted into the instrument panel. The instruments have the look of expensive sport timepieces and are lit with ice-blue LED lights. The center stack, housing the climate and “infotainment” controls, was designed to allow for a lower, driver-centric instrument panel profile. Features such as a thick-rimmed, leather-wrapped steering wheel and firm, highly bolstered and leather-covered seats also support the sport-oriented driving experience.

“There is great design harmony between the exterior and interior,” said Cafaro. “The feeling of flow and motion carries through in an engaging manner that makes you want to take the Regal out to your favorite twisting road to see what it can do.”

A breakthrough interior

The Regal’s finely crafted, sporty and well-appointed interior builds on the exceptional attention to detail found in the Enclave and LaCrosse, blending signature styling cues with contemporary sport sedan aesthetics.

Regal’s firm, highly bolstered seats were benchmarked against the top import competitors for comfort and support, while a standard flow-through center console offers plenty of storage for passengers in the front and back.

Smart applications of technology are also hallmarks of the Regal, including details such as an available multi-function controller on the center console for operation of the audio system, navigation system and Bluetooth or OnStar hands-free calling. The faceplate for the “infotainment” screen is set at a 30-degree angle to contribute to the car’s flowing interior design.

A new era in Buick design is also seen in the satin metallic, piano black and new, Kibo-patterned interior trim materials. Kibo is a rich, dark, progressively grained wood that lends an international flair to the Regal.

Under the hood

Unique with its all-four-cylinder powertrain, the Regal relies on the excellent horsepower-per-liter ratio of the Ecotec engine family to deliver smart, on-demand performance that is also very efficient.

Both the standard 2.4L engine and the available 2.0L turbo use direct injection technology to optimize performance, reduce emissions and maximize fuel efficiency. The 2.0L turbo is FlexFuel-capable, meaning it can run on gasoline, E85 ethanol or any combination of the two fuels.

The 2.4L is the same engine offered in the Buick LaCrosse, but in the smaller, lighter Regal, it delivers more agile performance. The 2.0L turbo cements the sport sedan credibility of the Regal, with on-demand power comparable to a V-6, but the inherent efficiency of a four-cylinder. To ensure responsive power across the rpm range, the 2.0L turbo uses a twin-scroll turbocharger that builds power quickly at lower rpm.

Distinct, uniquely calibrated six-speed automatic transmissions are paired with each engine as standard equipment. Both offer driver shift control that enhance the sporty driving feel of the Regal. Models with the 2.0L turbo are also offered with an optional six-speed manual transmission.

Driving experience

The chassis and structural systems were developed in Germany and give the Regal the handling and dynamics of a premium European sport sedan, as well as the quiet, refined ride and road manners expected of a Buick. The body structure is one of the most rigid in the segment, which is approximately 25-percent stiffer than the previous Regal. This solid structure supports more precise suspension tuning and a quieter ride.

A relatively long wheelbase of 107.8 inches (2738 mm) gives the Regal refined, well-balanced vehicle dynamics and supports comfortable ride tuning. Additionally, an independent MacPherson strut-type front suspension with single-path mountings and hydraulic ride bushings; a four-link independent rear suspension; hydraulic rack-and-pinion steering; and optimized four-wheel disc brakes are optimized to the capability of the individual powertrains and tailored to the expected use by drivers. Models equipped with the 2.0L turbo engine, for example, feature larger brakes.

Latest-generation electronic stability control (ESC or StabiliTrak), anti-lock brake system (ABS) and traction control system (TCS) are standard with Buick’s innovative, Interactive Drive Control real-time damping system offered on CXL Turbo.

Interactive Drive Control System

Regal’s Interactive Drive Control System chassis technology (available on CXL Turbo) offers enhanced vehicle stability and greater driving safety. It is designed to change the personality of the car based on the personality of the driver. 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 driver selections.

All four dampers are electronically controlled and continuously adapt within milliseconds to the prevailing road conditions, vehicle movements and individual driving style. Chassis settings are adjustable by the driver, with Standard, Tour and Sport settings.

Interactive Drive Control allows the driver to choose between three different operating modes that change the suspension and stability settings, throttle response, shift pattern and steering sensitivity through the variable effort steering system.

Selecting “Sport” mode optimizes the car for dynamic driving, tightening the suspension and steering response and speeding up the reaction of the automatic transmission. The “Tour” mode is optimal for long-distance cruising or rough road conditions, providing an increase in comfort. “Standard” or Default Mode is the perfect all-around setting for daily commuting and city traffic. The other major benefit of Interactive Drive Control is that it automatically adapts Regal’s performance settings to individual driving styles. When a driver begins to drive more aggressively it will tighten the suspension and increase steering effort and change to a more aggressive throttle response. When the vehicle senses that the driver is doing relaxed cruising, it adjusts settings for rolling smoothness and comfort.

Apart from a more rewarding driving experience, Interactive Drive Control also offers safety benefits in emergency situations. For example, if an obstacle must be avoided when the car is in Tour mode, various chassis sensors convey this to the DMC and the dampers are stiffened within milliseconds, delivering greater body control.

Detroit -  Further demonstrating Buick’s ongoing commitment to quality, J.D. Power and Associates announced today that Buick tied for the highest ranking in vehicle dependability for three-year old models.  The Buick LaCrosse was also ranked first in the midsize car segment, beating the Toyota Camry, while the Buick Lucerne came in second in the large car segment.

For the seventh straight year, Buick has ranked in the top ten brands in the J.D. Power and Associates dependability study, which tracks vehicle issues over a three-year ownership period and this year evaluates more than 200 problem areas. Buick moved from sixth place to take over the top spot in this year’s study.

“Quality and craftsmanship have always been one of the defining characteristics of the Buick brand,” said Susan Docherty, GM North America vice president for Buick, Pontiac and GMC.  “The added value of that dependability, combined with premium materials and refined, responsive performance, is something our customers have come to expect from every Buick, and it’s the driving force behind the continuing transformation of the brand.”

In addition to the latest J.D. Power and Associates honor, Buicks have been recognized with numerous “recommended” and “best buy” designations by leading consumer magazines and websites for all three current models:  Enclave, Lucerne, and LaCrosse.  Building on that tradition, an all-new 2010 Buick LaCrosse luxury sedan will arrive in showrooms this summer.

Buick is a division of General Motors Corporation (NYSE: GM) and markets the Enclave, Lucerne and LaCrosse as part of an integrated Buick-Pontiac-GMC retail channel in North America, and is a cornerstone of GM’s expansion in China.  For the 2010 model year, Buick will be introducing an all-new LaCrosse luxury mid-size sedan.  More information on Buick and its products can be found on our website here.
