2012 Regal to Offer New eAssistTM Fuel-Saving Technology

• eAssist “light electrification” system improves fuel economy 25 percent
• Estimated 26 mpg city / 37 mpg highway (pending EPA certification)
• On sale this fall

CHICAGO – Buick announced the 2012 Regal with eAssistTM fuel-saving technology, which improves overall fuel economy by 25 percent over the 2011 four-cylinder/six-speed powertrain. Estimated fuel economy is 26 mpg city and 37 mpg on the highway (pending EPA certification).

Regal with eAssist joins the 2012 LaCrosse as the second Buick to feature the efficiency-enhancing technology. The system uses a state-of-the-art lithium-ion battery system, electric induction motor-generator and regenerative braking capability to improve fuel economy. Its fuel economy tops competitors such as the Acura TSX, rated at 22 mpg city and 31 mpg highway. Regal’s estimated 37 mpg on the highway is 20 percent greater and the TSX doesn’t offer a six-speed automatic transmission, which is standard on the Buick.

“Buick’s eAssist technology means customers don’t have to trade a premium driving experience for efficiency,” said Tony DiSalle, vice president of Buick marketing. “We believe Regal and LaCrosse with eAssist provide more logical and affordable choices, compared to other hybrid midsize and full-size luxury sedans.”

Regal with eAssist goes on sale this fall. It joins an expanding lineup that also includes 2.4L and 2.0L Turbo (with manual transmission) models, as well as the upcoming Regal GS. Regal with eAssist offers the range of luxury and convenience packages offered in the other models, along with unique features that include:

Lightweight 17-inch alloy wheels and tires with lower rolling resistance
A driver-selectable, fuel economy-optimizing mode for the air conditioning system, which enables more frequent and longer-duration engine stop periods
An ECO gauge on the instrument panel that continuously responds to driving behavior, enabling the driver to drive with greater efficiency
A powerflow readout in the 7-inch infotainment screen, which shows the flow of energy through the electric assist system, such as battery charging from regeneration and electric power directed to the engine.
eAssist details
Mated to Regal’s 2.4L Ecotec direct injection four-cylinder engine and next-generation six-speed automatic transmission, the eAssist system uses power stored in the battery to provide needed electrical boost in various driving scenarios, optimizing engine and transmission operation. An advanced 115V lithium-ion battery and latest-generation 15-kW induction motor-generator unit help increase fuel economy through:

Regenerative braking, which provides up to 15 kW of electricity to charge the battery
Providing up to 11 kW (15 hp) of electric power assistance during acceleration
Automatic engine shut-off when the vehicle is stopped
Aggressive fuel cut-off during deceleration down to zero vehicle speed, enabled by the torque smoothing provided by the induction motor-generator unit
Intelligent charge/discharge of the high-voltage battery.
“The capability to deliver electric boost to the powertrain system during heavy acceleration and grade driving enables the engine and transmission to operate more efficiently,” said Steve Poulos, global chief engineer of the eAssist system. “Full fuel shutoff at stops and during deceleration complements electric boost and regenerative braking with additional fuel savings.”

Regal with eAssist technology also features improved underbody aerodynamics and tires optimized for performance and fuel economy. It also features a hill-assist system that captures brake pressure to help the driver more comfortably accelerate from a stop on a moderate or steep grade. It does this by greatly reducing the tendency of the vehicle to roll backward with the engine in shut-down mode.

The eAssist system’s 115V air-cooled lithium-ion battery bolsters the 2.4L Ecotec four-cylinder engine with approximately 11 kW (15 hp) of electric power assist during heavy acceleration and 15 kW of regenerative braking power. The system also enables the Ecotec engine to shut down fuel delivery in certain deceleration conditions, which saves additional fuel. While in fuel shut-off mode, the induction motor-generator unit continues spinning along with the engine to provide immediate and smooth take-off power when the driver presses on the accelerator. Then, as the vehicle comes to a stop, the induction motor-generator unit spins the engine, bringing it to a smooth stop – properly positioned for a smooth restart.

“The battery system is designed to provide power assistance to the internal combustion engine, rather than store energy for all-electric propulsion,” said Poulos. “It’s really an extension of the conventional internal combustion engine, not a replacement for it.”

The eAssist power pack contains the lithium-ion battery pack, the integrated power inverter and 12V power supply. It is located in a compartment between the rear seat and trunk; and it is surprisingly compact and lightweight, weighing only about 65 pounds (29 kg). Trunk space is slightly reduced when compared with 2011 models with the four-cylinder/six-speed powertrain, but still offers 11.1 cubic feet (314 liters) of storage. A quiet electric fan cools the power pack, drawing air from a vent located in the package tray, behind the rear seat.

The eAssist system’s electric induction motor-generator is mounted to the engine in place of the alternator to provide both motor assist and electric-generating functions through a unique engine belt-drive system. The induction motor-generator is a high-performance, compact induction motor that is liquid-cooled for increased performance and efficiency.

Next-generation six-speed
The eAssist system works with Regal’s direct injected 2.4L Ecotec four-cylinder and next-generation six-speed automatic powertrain combination. In the Regal with eAssist, the engine is rated at 182 horsepower (136 kW) and the next-generation Hydra-Matic 6T40 takes transmission technology to the next level with features designed to enhance powertrain efficiency.

Significant internal transmission changes to clutch controls and hardware provide reduced spin losses while improving shift response and time. The added electric power provided by the eAssist system allows for higher gearing to improve steady state efficiency without impacting acceleration performance or driveability. The system’s ability to provide some electric assistance at cruising speeds allows the driver to accelerate lightly or ascend mild grades without the transmission downshifting.

An auxiliary, electric-driven transmission oil pump is added to the 6T40, which keeps the transmission primed and the fluid flowing when the engine shuts down at a stop. That keeps the transmission ready to perform when the driver accelerates, for a seamless, uncompromised driving experience.

Buick has officially unveiled the 2012 Buick Verano. The car will reveal at the North American International Auto Show. 2012 Buick Verano features an attractive design that echoes the Regal  and LaCrosse. Notable highlights include a waterfall grille, blue-translucent projector beam headlights, and 17-inch alloy wheels.

Buick Introduces The All-New 2012 Verano

Compact Luxury Entry is Buick’s Third New Model in Two Years

DETROIT – The all-new 2012 Buick Verano compact luxury sedan, the brand’s third new model in the past two years and first in the compact luxury segment, will be revealed at the North American International Auto Show.

Verano goes on sale in the fourth quarter of 2011, the latest model in a product renaissance that began with the Enclave and continued with the LaCrosse and Regal. Like them, Verano is distinguished by luxury and technology, including 10 standard air bags, an available heated steering wheel and a next-generation radio system with OnStar-powered connectivity that enables seamless communication between the Verano and the driver’s smart phone.

An Ecotec 2.4L and six-speed automatic powertrain combination is standard and delivers an estimated 177 horsepower (132 kW) and 170 lb.-ft. torque (230 Nm), 0-60 mph performance of 8.0 seconds and an estimated 31 mpg on the highway. A 2.0L turbo engine will be offered in the future.

“Verano expands our lineup, continues Buick’s momentum and gives us a great opportunity to attract a new generation of customers with a product that delivers on their expectations for design, performance and technology,” said John Schwegman, vice president of Buick marketing. “It is a smart choice that delivers unexpected luxury in a compact sedan – and it will compete head-to-head with competitors from Audi and Lexus.”

Five elements infused in Verano that define its character:

• Sculpted design – Refined styling with a sporty profile, blending Buick’s signature cues – including a black chrome waterfall grille, blue translucent projector beam headlamps, portholes and chrome accents
• Luxurious interior – Premium seat comfort and support redefined for a compact sedan and matched with upscale, soft-touch materials and premium leather – all complemented by leading-edge infotainment and ambient lighting
• Quiet tuning – The quietest compact sedan on the road – quieter than many midsize and full-size cars – Verano’s quietness is supported by acoustical laminated glass, triple door seals, refined chassis dynamics and specially manufactured 17-inch standard forged alloy multi-spoke wheels, which minimize road noise
• Refined and responsive performance – Powerful and efficient Ecotec 2.4L/six-speed automatic powertrain matched with a refined, responsive suspension system, including a sophisticated Watts Z-link rear suspension and four-wheel disc brakes with standard anti-lock brakes, full-function traction control and StabiliTrak electronic stability control
• Purposeful technology – Convenience and safety features that enhance the driving experience and are rare for the segment, including 10 standard air bags, a next-generation radio, touch screen navigation and advanced connectivity technologies powered by OnStar.

Sculpted design

Verano carries the modern Buick design cues introduced on the Enclave and interpreted for the LaCrosse and Regal. They include a bold, detailed black chrome waterfall grille, prominent blue translucent projector beam headlamps, portholes, chrome accents, premium wheels and a tailored body-to-wheel relationship. An arching roofline connects a steeply raked windshield and fast-sloping rear pillars to give the car a sporty profile that’s complemented by large, 17-inch standard multi-spoke forged alloy sterling silver-finish wheels. Two premium 18-inch wheel designs are available.

“Verano translates Buick’s sculptural design language in a new size, with all the refinement and attention to detail pioneered by the Enclave and LaCrosse,” said Dave Lyon, design director. “Beyond all that, it’s simply a great-looking car. It has great proportions and sophisticated details that will look great for years to come.”

Unique to Verano are translucent blue projector-beam headlamps, which give the car a distinctive, upscale appearance. A palette of rich colors enhances the premium look, including Claret Red Tintcoat and White Diamond Tricoat. Other exterior color choices include Black, Olympic White, Switchblade Silver Metallic, Cyber Gray Metallic and Mocha Bronze Metallic.

Luxurious interior

Complementing Verano’s precisely crafted, premium-accented exterior is an interior marked by exceptional seat comfort and support, as well as premium soft-touch materials, including ambient lighting inspired by the LaCrosse. Metallic and wood trims and warm ambient lighting make the cabin an inviting environment.

Neutral and medium titanium colors are offered on interiors with leatherette/fabric seating surfaces, while ebony, cashmere and a unique Choccachino color are offered on the available leather-trimmed interiors. Verano uses the same premium leather material for the seats that is used on the LaCrosse.

The instrument panel blends with an integrated center stack that houses the infotainment display, climate controls and radio controls. Flush-mounted components within the center stack have a gap tolerance of less than 1 mm, while the instrument panel-to-door panel gaps are less than 5 mm. Those tolerances are among the best in class.

Verano’s headliner cover is made of a knit material that is one of five layers of an acoustically designed headliner to help quiet the passenger compartment. The interior pillar and other moldings are color- and grain-matched to the headliner.

Additional interior standard and available features include:

• Push-button engine start
• Dual-zone climate control with standard air conditioning (automatic climate control available)
• Heated steering wheel
• Heated leather-appointed seating
• Electronic parking brake
• Console armrest that slides and locks
• Power windows with express up/down in the front and express down in the rear
• Steering wheel radio controls
• Uplevel front and rear reading lamps.

Verano’s heated steering wheel and heated seats are linked with the remote start feature. In temperatures lower than 45 F (7 C), the steering wheel heater and seat heaters automatically activate.

Quiet tuning

Verano delivers the library-quiet driving experience for which Buicks have become known. Quiet-tuning systems, processes and components are built into every facet of the vehicle’s architecture. All are designed to block or absorb sound and dampen or eliminate vibrations.

Hydraulic ride bushings, for example, and an isolated engine cradle reduce or eliminate vibration pathways that could be transmitted to the passenger compartment. Similarly, a number of noise-reducing and noise-cancelling technologies are employed throughout the body structure, including:

• The steel front-of-dash panel is sandwiched between two damping mats
• Nylon baffles are used in various hollow portions of the body structure and filled with sound-absorbing foam that expands when the body enters the paint oven
• The headliner comprises five layers of thermal fiber acoustic material, including a premium woven fabric on the visible outer layer
• Patches of sound-damping material are applied strategically throughout the body structure and melt into place when the body passes through the paint oven, allowing the patches to follow the contours of the sheet metal below
• Sound insulation material between rear-body structural components that is made from recycled denim
• Triple-sealed doors that feature fiberglass “blankets” serve as water, airflow and noise barriers. The doors are also beta-braced, meaning they close with a solid, precise sound and no resonance
• Optimized windshield and side glass for quietness, with 5.4-mm-thick laminated windshield and 4.85-mm laminated side glass
• The engine’s intake and exhaust systems are tuned for quiet performance
• Isolated brake and fuel lines prevent vibrations.

Even the wheels and tires contribute to Verano’s quietness. The standard 17-inch aluminum wheels are manufactured in a unique way to enhance quietness, while the tires minimize road noise.

Refined and responsive performance

A power-dense Ecotec 2.4L four-cylinder, with dual-overhead camshafts, variable valve timing and E85 capability, is the standard engine in the Verano. It produces an estimated 177 horsepower (132 kW) and 170 lb.-ft. of torque (230 Nm). Direct injection technology helps it produce more power with less fuel and lower emissions – including up to 25-percent reduced hydrocarbon emissions when compared with a multi-point fuel injection engine. The engine is matched with a six-speed automatic transmission that helps the Verano deliver an estimated 31 mpg on the highway. Electric power steering and a more efficient transmission design help optimize fuel economy.

The front suspension uses decoupled MacPherson struts for better isolation, providing greater separation of extreme road conditions – large potholes, for example – from everyday driving conditions. At the rear, a technically advanced Watts Z-link design helps center the rear axle during cornering, which helps keep the Verano’s handling responses symmetrical on both left-hand and right-hand turns. The linkage’s capability to center the axle during cornering delivers a more-balanced driving experience because the rear suspension better follows the lead of the front suspension.

The Z-link design is also lighter and requires less space than a typical fully independent rear suspension. The lower weight contributes to Verano’s fuel economy, while the compact design enables more trunk space.

Steering inputs are executed by an electric power steering system, featuring a dual-pinion rack. Electric powering steering helps save fuel because it removes the conventional power steering pump from the engine’s driven accessories. Engineers tuned the speed-sensitive system to provide quick, direct reaction to steering actions and a strong on-center feel. The system has a ratio of 15.5:1 and requires only slightly more than two turns, lock to lock.

Stopping power is handled by a four-wheel disc brake system with standard anti-lock and electronic brake force distribution, as well as StabiliTrak electronic stability control with traction control.

Purposeful technology

Comprehensive connectivity is enabled by OnStar’s remote vehicle access, which makes keeping tabs on the vehicle a breeze from anywhere with a smart phone. Highlights include:

• Passive entry
• Heated steering wheel
• Touch screen navigation system
• Bluetooth connectivity (both phone and audio)
• XM Satellite Radio
• Bose sound system
• Next-generation radio.

Downloading an OnStar app enables the use of remote vehicle features from anywhere in the world. With a few taps, customers can check the:

• Fuel tank level and range
• Fuel mileage
• Remaining oil life
• Tire pressure
• Odometer reading.

Other remote-access features include remote vehicle locking/unlocking, remote vehicle start and a vehicle locator.

The next-generation radio system includes a navigation system, along with USB and auxiliary input jacks, and includes full Bluetooth with streaming audio, structural speech recognition, SMS texts and more. Additional connectivity features include text-to-speech conversion of SMS texts, smart phone app integration (Pandora, Stitcher, etc.) and Gracenote music organization for external devices (USB drives, etc.), including Playlist Plus and Album Art features.

Safety is another component in Verano’s technology story. Primary features include:

• Ten standard air bags, including frontal, head curtain side air bags, front and outboard rear-seat side-impact air bags and new knee air bags. The head-curtain side air bags deploy in a rollover crash
• StabiliTrak electronic stability control, traction control and anti-lock brakes
• Collapsible pedal system, which allows the pedals to detach during a crash to reduce the risk of leg or ankle injuries
• OnStar with Automatic Crash Response.

Verano has a strong, unitized body structure that incorporates 60-percent high-strength steel in key areas to enhance strength and crash protection. It is used to help prevent intrusion into the passenger compartment. Safety development included testing at GM’s rollover test facility.

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 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
• 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 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.

Power for the Buick Regal GS comes from a high-output 2.0L Ecotec turbocharged engine with direct-injection technology. It is based on the engine that will be offered on Regal CXL models later this summer, but the engine and turbocharger are tuned to deliver greater boost pressure in the GS. The output is estimated at 255 horsepower (190 kW) and 295 lb.-ft. of torque (400 Nm).

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 2.4L is the same engine offered in the Buick LaCrosse, but in the smaller, lighter Buick Regal, it delivers more agile performance. The 2.0L turbo cements the sport sedan credibility of the Buick 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. Both offer driver shift control that enhances the sporty driving feel of the Buick Regal.
