Buick today introduced the all-new 2013 Encore – a luxury small crossover that delivers Buick’s signature style, interior acoustic refinement and collection of luxury amenities in a maneuverable, versatile and efficient package.

The Encore is on display at the North American International Auto Show in Detroit through Jan. 22, and goes on sale in early 2013.

“Buick Encore is a great-looking, smart choice for those who want luxury crossover amenities in a more maneuverable and agile vehicle,” said Tony DiSalle, U.S. vice president of Buick Marketing. “It represents a luxury alternative for a new audience of Buick customers, and delivers features and flexibility not typically found in vehicles of its size today.”

Buick models continue to gain in popularity, with two consecutive years of higher retail sales. The Encore joins Verano – Buick’s third all-new sedan in three years – to round out the brand’s lineup and continues the momentum established by the Enclave crossover almost five years ago.

With room for five and up to 48.4 cubic feet (1,372 liters) of storage space with the rear seat folded, the Encore offers substantial cargo capacity along with the confident, higher driving position, all-wheel-drive capability and contemporary styling of a crossover. In fact, its cargo space compares favorably against similar-sized international competitors:

Additional features include 10 standard air bags and an Ecotec 1.4L turbo four-cylinder/six-speed automatic powertrain, along with standard and available technologies such as Buick’s voice-activated IntelliLink – which uses Bluetooth or a USB to connect the driver’s smartphone to a high-resolution, full-color seven-inch LCD display radio.

And because it’s a Buick, QuietTuning is standard on the Encore, which also features Buick’s first use of active noise cancellation technology.

Contemporary design offers versatile spaciousness

In keeping with the global design language that has come to symbolize the brand, the Encore’s sculpted and elegant styling traits – including sweeping character lines – make it instantly identifiable as a contemporary Buick. Signature cues include a waterfall grille, chrome accents and surrounds, portholes on the hood and painted lower panels, similar to the Enclave.

“The Encore brings Buick’s timeless, sculptural design to the crossover segment in a way that blends elegance, efficiency and utility,” said David Lyon, executive director of design. “There’s confidence in its athletic stance and elemental beauty in its rich details.”

Blue-accented projector-beam headlamps and detailed taillamps enhance the premium appearance; and 18-inch, five-spoke painted aluminum wheels are standard. Seven-spoke chrome wheels are available.

Inside, the Encore’s organic styling carries over to a flowing instrument panel that wraps naturally into the door panels. A prominent central instrument panel houses the large, full-color, seven-inch LCD display for the IntelliLink voice-activated radio system. It also features displays for the SiriusXM satellite radio, as well as available navigation and rear camera systems.

A contemporary mix of dark and light tones distinguishes the cabin, which is accented with ice blue ambient lighting, select use of bright trim and wood-grain trim. Premium seats featuring high-density foam for greater comfort on long drives are trimmed with either a contemporary cloth/leatherette motif or available leather. Heated front seats and a heated steering wheel are available. The rear seat features a fold-down armrest with cup holders.

More of the Encore’s comfort and luxury features – standard and available – include:

• Remote vehicle start
• Dual-zone automatic climate control
• Rainsense wipers
• Bose premium sound system
• Heated, leather-wrapped steering wheel with audio controls
• Six-way, power-adjustable driver’s seat with power lumbar adjustment and driver memory.

Encore also features plenty of storage capacity and storage compartments. It offers 18.8 cubic feet (533 liters) of storage behind the split-folding rear seat and 48.4 cubic feet (1,372 liters) with the rear seat folded. With the rear seat in place, there’s room for at least six full grocery bags and with the rear seat folded, there’s room for golf clubs and overnight bags for a weekend getaway. Even the front passenger seat folds flat to extend the cargo length and accommodate long items that would not normally fit in a vehicle of this size.

Nine exterior colors and three interior color combinations will be offered.

QuietTuning gets ‘active’

QuietTuning is the process of defining Buick quality, sound and vibration characteristics and designing and refining the vehicle following a three-point strategy of reducing sounds at their source, blocking sounds from entering the cabin and absorbing any remaining sounds.

For the Encore, specific content was applied to achieve 40 sound benchmarks for refinement, including Buick’s first application of active noise cancellation. With it, ceiling-mounted microphones detect engine noise, the frequencies of which are processed by a computer that directs counteracting sound waves through the audio system’s speakers and subwoofer.

Additional standard QuietTuning features include:

• Acoustically treated headliner with a tuned gap between it and the high-strength-steel roof panel
• Sound-absorbing materials used in the cabin, under the hood and in the wheel house liners
• HydraMatic 6T40 six-speed transmission with neutral gear disengagement
• Quiet-tuned 18-inch Continental tires
• Aero-optimized outside mirrors
• Ultra-quiet engine alternator
• Acoustic-laminated windshield and thicker 5mm side window glass
• Foam baffle insulation at the opening of body structure cavities.

‘One-tire’ philosophy sharpens ride and handling characteristics

The new Encore is built on a global small-crossover platform and engineered with a “one-tire” philosophy. Everything is optimized around a single 18-inch tire specification, designed for more precise suspension tuning, driving refinement, quietness and a feeling of control.

The Encore’s 100.6-inch (2,555 mm) wheelbase and wide stance – 60.6-inch (1,540 mm) front and rear tracks – contribute to a more confident-feeling driving experience, while a strong structure enables greater suspension precision and a quieter ride. Tuned engine, including two hydraulic mounts, are tailored to the engine’s inherent torque axis to disrupt the transmission of vibration and noise. This configuration also helps control the transfer of momentum, resulting in improved dynamic balance.

A MacPherson strut front suspension is used with coil springs, a large stabilizer bar and side-load-compensated front strut modules. The rear suspension incorporates a compound crank (torsion beam) design, with a double-wall, tubular V-shape beam profile with gas-charged twin-tube shocks. It combines all the advantages of a conventional torsion beam axle, including minimal space requirements, with low weight and consistent camber control. Urethane spring isolators are used to dampen noise.

The Encore also features a column-mounted, variable-effort electric power steering system. It contributes to a 36.7-foot (11.2 meters) turning diameter, while also saving fuel compared to an engine-driven power steering pump.

Safety technology helps protect occupants

Encore is designed with technologies – including radar-based features – to help avoid crashes and protect occupants in case one occurs. Technologies that help avoid them include:

• Standard StabiliTrak electronic stability control
• Four-wheel disc brakes with ABS and electronic brake force distribution
• Cornering brake control and brake assist
• Available all-wheel-drive system that seamlessly shifts power to the rear wheels when required for better traction and handling
• Available forward collision alert and lane departure warning
• Available front and rear park assist
• Available rear vision camera.

When it comes to occupant protection, the Encore’s body structure forms a protective cage around the passenger compartment. Sixty-three percent of the underbody structure is comprised of high-strength steels, while 57 percent of the upper body uses high-strength steels, including ultra-high-strength steel. That protection is complemented with 10 standard air bags, which include:

• Driver and front passenger frontal air bags
• Driver and front passenger knee air bags
• Front and rear thorax air bags (all outboard positions)
• Side curtain air bags for front and rear outboard passengers.

Encore’s suite of safety features is rounded out with exclusive OnStar technology, which includes the Advanced Crash Response System, emergency assistance and more.

Ecotec turbo engine drives efficiency

The Buick Encore is powered by an efficient, power-dense Ecotec 1.4L turbocharged four-cylinder engine and six-speed automatic transmission. It generates an estimated 140 horsepower (103 kW) and 148 lb.-ft. of torque (200 Nm) between 1,850 rpm and 4,900 rpm. The wide rpm range for the maximum torque – a specific trait of turbocharged engines – helps it deliver a better driving experience and performance.

The 1.4L’s turbocharger is integrated within the exhaust manifold, for reduced weight and greater packaging flexibility. A reinforced crankshaft and forged connecting rods deliver additional strength to support the engine’s pressurized power and torque over a wide rpm band.

Several of the engine’s features contribute to the Encore’s overall fuel efficiency, including:

• A high-efficiency alternator
• Regulated voltage control
• Electronically controlled returnless fuel system
• Deceleration fuel cut-off.

They complement other vehicle-wide systems and components that also help improve efficiency, including low-rolling-resistance tires, electric power steering, neutral idle feature and optimized aerodynamics.

A Hydra-Matic 6T40 six-speed automatic transmission backs the Ecotec 1.4L turbo engine. It is part of a family of six-speed front and all-wheel drive transaxles developed for small cars and crossovers. It has a unique design, with the planetary gearsets positioned on the same axis as the engine crankshaft centerline, making the entire powertrain unit shorter fore-to-aft. This design enables a shorter overall vehicle length, increased interior space, enhanced safety crush zones and lower weight.

The Hydra-Matic 6T40 offers a “steep” first gear and a “tall” overdrive top gear to achieve a wide ratio spread of 6.14:1. This allows the Encore to achieve robust acceleration, as well as fuel efficiency and lower engine noise at highway cruising speeds. A neutral-gear disengagement feature helps enhance smoothness and efficiency.

The Buick Encore will begin arriving at U.S. Buick dealerships in the first quarter of 2013.

Buick Verano delivers key luxury features and characteristics found in the Buick LaCrosse, in an efficiently packaged, right-sized vehicle for the compact luxury market. It is the brand’s third all-new model in the past two years and the first in the compact luxury segment.

Verano is the latest model in a Buick 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 Buick IntelliLink radio system with Bose Premium Audio and OnStar-powered connectivity that enables seamless communication between the Verano and the driver’s smartphone.

The all-new Buick IntelliLink system uses Bluetooth or USB to connect the driver’s smartphone to a seven-inch, LED high-resolution, full-color touch screen display radio. IntelliLink expands on Buick’s current Bluetooth and USB capabilities to allow smartphone control via voice activation and steering wheel-mounted controls.

Verano Quiet Tuning features

Quiet-tuning systems, processes and components are built into every facet of the Verano’s architecture. All are designed to block or absorb sound and dampen or eliminate vibrations.

• 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.
• Liquid applied sound deadener is robotically applied throughout the body structure to both deaden and dampen unwanted noises and vibrations.
• Sound insulation material between rear-body structural components 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 acoustic laminated windshield and 4.85-mm acoustic laminated side glass.
• The engine’s intake and exhaust systems are tuned for quiet performance
• Isolated brake and fuel lines prevent vibrations.

Verano powertrain

• Ecotec 2.4L four-cylinder, with dual-overhead camshafts, variable valve timing and E85 capability is standard and is rated at 180 horsepower (134 kW) and 171 lb.-ft. of torque (232 Nm).
• Each piston has its own directed jet that sprays oil toward its skirt, coating its underside and the cylinder wall with an additional layer of lubricant. The extra lubrication cools the pistons, reducing friction and operational noise, while also bolstering the engine’s durability.
• Direct injection technology helps the engine 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.
• E85 is a clean-burning, domestically produced alternative fuel, composed of 85 percent ethanol alcohol and 15 percent gasoline. Ethanol is renewable, biodegradable and produces fewer greenhouse gases in the combustion process.
• Standard six-speed automatic transmission helps the Verano deliver an EPA-estimated 32 mpg on the highway.
• Electric power steering eliminates the conventional hydraulic engine-driven steering system, which helps save fuel and improves reliability.

Verano chassis and suspension

• 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.
• The rear suspension features a Watts Z-link design that 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 Z-link design is lighter and requires less space than a typical fully independent rear suspension, enhancing fuel economy and enabling more trunk space.
• Steering inputs are handled 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.
• The steering 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.

Verano safety and crash avoidance features

The Verano is designed to help drivers avoid crashes, while protecting the occupants in the event a crash occurs.

• 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
• Collapsible pedal system, which allows the pedals to detach during a crash to reduce the risk of leg or ankle injuries.
• StabiliTrak electronic stability control system helps reduce the risk of rollover crashes by keeping the vehicle in the driver’s intended path by applying throttle, braking or a combination of both.
• Power-assisted four-wheel disc brakes are standard.
• Four-channel anti-lock braking is standard and incorporates electronic brake force distribution, which balances braking performance based on such factors as road conditions and the weight of passengers and/or cargo.
• Pretensioners minimize forward movement during a collision, and are standard on the front safety belts. Load-limiting retractors cinch the belt more tightly.
• LATCH (Lower Anchors and Tethers for CHildren) child seat attachment system, which is included in all second-row seating positions.
• Tire pressure monitoring system is standard on all models.
• Strong body structure to absorb crash energy and provide a protective “safety cage” around occupants. More than 60 percent of the body structure is composed of advanced steels.

GMC today unveiled the new 2013 Acadia and Acadia Denali at the Chicago Auto Show, highlighting a new exterior and safety features including the industry’s first front center air bag.

Acadia, which launched in 2007 as GMC’s first crossover and defined a segment that has since surged in popularity, had the best sales in its five-year history in 2011. The Denali model, added in mid-2010, broadened Acadia’s appeal to luxury customers with its combination of functionality and style.

“With an award-winning combination of space, capability and fuel-efficiency, Acadia epitomizes GMC’s ‘never say never’ attitude,” said Tony DiSalle, U.S. vice president of GMC Marketing. “For 2013, our engineers and designers applied that same attitude to developing the new Acadia.”

Acadia retains the interior functionality popular with families, including the SmartSlide seating system, which allows easy access to the third row for both seven- and eight-passenger seating configurations. Likewise, both the second and third row still fold flat for class-leading maximum cargo space, including the ability to carry 48-inch-wide sheet goods, such as drywall and plywood.

Confident design

First impressions are everything, and the 2013 Acadia was developed to make a strong one. A chiseled, three-bar grille sits prominently in the new, more upright design.

Diffused LED running lamps lend a premium look to the Acadia and are standard on all models, regardless of whether standard projector beam or optional HID headlamps are selected. New taillamp detailing reflects the advancements up front.

The new Acadia gets other subtle exterior design updates, including wrap-around rear glass and a new rear spoiler. New 18-, 19- and 20-inch wheel patterns complement the vehicle’s lines and stance.

The Acadia’s refined interior uses upgraded soft-touch materials, with French stitching that adds a tailored look and red ambient light flowing across the dashboard. SLT and Denali models get aluminum accents on the center console, doors and dash.

Industry-exclusive safety

The redesigned Acadia will be the first vehicle on the market with GMC’s new front center air bag system, created to protect drivers and front passengers in far-side impact crashes where the affected occupant is on the opposite, non-struck side of the vehicle. It deploys from the inboard side of the driver’s seat and positions itself between the driver and front passenger.

“While no restraint technology can address all body regions or all potential injuries, the front center air bag is designed to work with the vehicle’s other air bags and safety belts to collectively deliver an even more comprehensive occupant restraint system,” said Gay Kent, GM executive director of Vehicle Safety and Crashworthiness.

Standard on the Acadia Denali and available on other models are Side Blind Zone Alert and Rear Cross Traffic Alert systems. These systems use radar to watch spots the driver may not be able to see – and provide visible and audible warnings to help prevent collisions.

Every Acadia model also comes standard with six months of OnStar’s Directions and Connections service, which includes automatic crash response, turn-by-turn navigation, roadside assistance, emergency services link and remote door unlocking. OnStar’s RemoteLink smartphone app allows for remote vehicle status reports, extended locking and unlocking capability, and remote start functionality to distance limited only by cellular phone service, rather than the few hundred feet of the standard key fob.

Technology leader

The 2013 Acadia’s redesigned infotainment functions feature capacitive touch controls that use electrodes to sense the conductive properties of objects such as the touch of a finger.

GMC’s Color Touch Radio – first introduced on the 2012 Terrain – is standard in the Acadia. Available IntelliLink allows customers to seamlessly integrate their smartphones for hands-free calling through the audio system and Bluetooth streaming of popular internet radio favorites Pandora and Stitcher. IntelliLink also allows voice control of USB-connected iPods for easy access to stored music.

Other audio system features include HD radio capability, a photo viewer and a standard rear-vision camera with dynamic guide lines that will display on the high-definition screen.

Mechanically, the 2013 Acadia benefits from a next-generation Hydra-Matic 6T70 six-speed automatic transmission with better shift response and improved drivability.

Acadia’s most-popular options, including rear-seat entertainment, a Dual SkyScape sunroof and a trailering package, continue to be available.

Exclusive Denali returns

Acadia’s popular, top-of-the-line Denali trim represents 30 percent of sales, so a high priority was placed on adding premium amenities and refining Denali’s signature design cues. New or redesigned exterior additions include:

• New, three-dimensional polished grille
• Redesigned lower front and rear fascias
• Body-color lower cladding and rocker moldings, rear fascia and fender flares

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.

A new, premium Denali model joins the GMC Acadia lineup for 2011, adding a new dimension of luxury and exclusivity to this popular crossover. It brings the distinctive Denali design elements, including a chrome honeycomb grille and monochromatic exterior color cues, along with exclusive fascias, high-intensity discharge headlamps and unique interior features.

“The GMC Denali models have come to stand for luxury and exclusivity, and that’s just what customers will get in the new Acadia Denali,” said Lisa Hutchinson, GMC product marketing director. “The decision to develop an Acadia Denali was made quickly within the new GM in response to customer and dealer demand for a Denali version ever since the launch and success of the Acadia.”

Indeed, the Acadia continues to win over customers. In a still-recovering market, Acadia sales were up nearly 45 percent in the first quarter of 2010, making it second in brand sales to only the broad Sierra range of trucks.

In addition to the new Acadia Denali, the Acadia is offered in two cloth trims, SL and SLE, and leather trims designated SLT1 and SLT2. All models are available in front-wheel-drive and all-wheel-drive with seven- or eight-passenger seating configurations. A comprehensive safety system includes six standard air bags and standard StabiliTrak electronic stability control system with traction control and rollover mitigation technology.

Acadia at a glance

Acadia’s body-frame integral structure enables lower entry/exit height for passengers. Despite the vehicle’s SUV-like front-end height, the front door step-in height is only 18.9 inches (480 mm); the rear door step-in height is 19.8 inches (503 mm). Entry to the second- and third-row seats is easy with very wide rear doors and GM’s exclusive Smart Slide second-row seat feature.

All models are powered by a 3.6L V-6 VVT engine that uses gasoline direct injection technology to optimize performance and fuel economy. The engine is paired with Acadia’s fuel-saving six-speed automatic transmission to help give FWD models an EPA-estimated 24 mpg on the highway. The Acadia also is capable of towing up to 5,200 pounds (2364 kg), when properly equipped.

Acadia’s interior exudes refinement and attention to detail, with many thoughtful features designed into a finely crafted environment. A car-like “low and away” instrument panel enhances the feeling of openness in the front-row seats and provides a commanding outward view. The instrument panel and other interior elements feature high-quality, low-gloss materials and tight gap tolerances.

Acadia Denali details

The 2011 Acadia Denali is available in front-wheel-drive and all-wheel-drive models, as well as seven- and eight-passenger seating configurations. It stands out with its signature Denali design cues, highlighted by the monochromatic exterior and chrome honeycomb grille.

Further distinction comes with 20-inch, two-tone chrome-clad wheels. The six-spoke wheels feature black chrome spoke inserts set against bright chrome. It is offered in five exterior colors: Quicksilver Metallic, Summit White, Carbon Black, Red Jewel Tintcoat and White Diamond Tricoat.

Seating and storage

All Acadia models offer three rows of seating that can be configured for seven or eight passengers, regardless of the trim level. The seating configurations include two front bucket seats, a 60/40-split second-row bench (three passengers) or two second-row captain’s chairs (two passengers) and a 60/40-split third-row bench seat. Generous storage space of 24.1 cu. ft. (682 liters) is available behind the third-row seat (with the cargo management removed).

GM’s exclusive Smart Slide feature is standard on all second-row configurations, allowing quick and easy access to the third-row seating area. The second-row seat cushion flips up while the seatback slides forward, effectively compressing the space occupied by the seat with the pull of a lever. The Smart Slide system also allows the second row to be positioned fore/aft. When adjusted rearward, the second-row seat provides more legroom for taller passengers; when adjusted forward, it provides more storage space or additional legroom for third-row passengers. Seating space is sufficient for adults in all positions.

Access to the third-row seat also is aided by Acadia’s rear door width, which is wider than the doors on most other SUVs. The vehicle’s long wheelbase also enables greater accessibility. The rear door opening was maximized by reducing the space between the rear door and the leading edge of the door opening. Engineers were able to maximize the opening space while providing optimal chassis integrity for maximum occupant protection.

Along with comfort and ease of entry, Acadia’s interior offers generous cargo room, including 115.9 cu. ft. (1,382 L) when the second- and third-row seats are folded flat and the cargo management removed. Additional storage is also available in a covered rear cargo convenience center behind the third row that allows items to be stored out of sight beneath the rear cargo floor.

Ride and handling

Acadia rides on a long 118.9-inch (3,020.7 mm) wheelbase and wide 67.28-inch (1,709 mm) front/rear tracks – a combination that lowers the center of gravity and enables smooth, stable ride and handling. Sharp reflexes are also supported by independent front and rear suspensions. The front suspension features a MacPherson strut design, with a direct-acting stabilizer bar and aluminum knuckles. Isolated mounting points help reduce noise and vibration.

The rear suspension uses a compact, state-of-the-art linked “H” design, which uses an isolated mounting system to reduce noise and vibration transmitted to the passenger compartment. This design enables the handling prowess that comes with an independent suspension, but with minimal floor pan intrusion – a feature that helps the Acadia offer generous passenger and cargo space.

Acadia features standard power-assisted rack-and-pinion steering, with variable-effort steering available. The suspension and steering system meet the road via standard 18-inch wheels and tires, with 19-inch wheels available. Four-wheel disc brakes with ABS are standard.

Acadia’s available Intelligent AWD system enhances dry-road handling and provides increased traction on wet, snow and ice-covered roads. It actively manages the torque distribution between the front and rear axles, based on factors such as wheel speed, throttle and surface conditions. There is no driver intervention; the system automatically decides how much torque to apply and it automatically delivers torque to the wheels that have the best traction. The AWD system’s tuning is revised to provide more rear torque bias during certain driving conditions.

Safety

Acadia’s 360-degree safety system helps protect passengers before, during and after a crash. A strong structure is the foundation, while a wide stance and low center of gravity helps reduce the likelihood of a rollover. Acadia’s structure is reinforced in numerous areas with high-strength steel, including a stiff steel cross-car beam welded across the floor between the B-pillars. It also uses dual-phase steel in select areas, such as the lower engine compartment rails. Dual-phase steel is strengthened in the paint oven and offers easier formability, reduced mass, greater strength and better crash energy absorption than most high-strength steels.

Acadia is equipped with six standard air bags: two dual-stage frontal air bags for the driver and front passenger; two seat-mounted side-impact air bags in the first row; and two head curtain side-impact air bags that cover all three seating rows. The head curtain side air bags are among the longest air bags in any production vehicle.

Complementing the air bags is GM’s rollover sensing system, which can preemptively activate the side-impact air bags if sensors determine a rollover is imminent. In the event of a rollover, the air bags stay inflated longer to provide increased occupant containment.

Acadia also comes standard with OnStar 9.0 (with a six-month Directions and Connections plan including Turn-by-Turn navigation and Destination Download) that features Automatic Crash Response.

Acadia is covered by GM’s five-year/100,000-mile powertrain warranty and three-year/36,000-mile bumper-to-bumper warranty – the best coverage in America.

GMC Sierra Denali 2500HD and 3500HD – the first offerings of the exclusive Denali line on a heavy-duty GMC pickup – lead a new Sierra heavy-duty truck lineup for 2011. The comprehensively redesigned roster of 2011 Sierra 2500HD and 3500HD trucks includes a new, more powerful 6.6L Duramax turbo diesel that delivers 397 horsepower (296 kW) at 3,000 rpm and 765 lb.-ft. of torque (1,037 Nm) at 1,600 rpm.

The new Sierra Denali HD is the latest expression of GMC’s Denali philosophy of blending capability with premium features and styling,” said Lisa Hutchinson, GMC product marketing director. “It is a premium tool that offers many comfort and infotainment features, along with a maximum towing capacity of 21,700 pounds with the more powerful Duramax diesel.”

The new Denali HDs are crew cabs available only in the 2500 series (3/4-ton), 2WD and 4WD configurations, as well as the 3500 Series (1-ton) 2WD and 4WD in both single-rear-wheel and dually versions. The 3500 series is also available in standard (6-foot 6-inches) and dually long box (8-foot) versions. A Vortec 6.0L gas V-8/six-speed automatic powertrain is standard and the new Duramax 6.6L turbo diesel/Allison 1000 six-speed transmission powertrain is available on all Denali HDs.

The iconic Denali four-bar, chrome grille with round air inlets distinguishes the Sierra Denali HDs on the outside, along with body-color bumpers, chrome door handles, chrome accents and 17- (Dually), 18- and 20-inch polished forged aluminum wheels. On the inside they include Denali-specific brushed aluminum trim, power-adjustable pedals, a Bose premium surround audio system and 12-way power seats. Along with an optional heated steering wheel, heated and cooled leather-appointed seating is available. The exterior is offered in three colors: Black, Stealth Gray and White.

The balance of the new 2011 Sierra HD lineup is identified on the outside by new, three-bar grilles and powertrain-badged louvered hoods, along with a revised, full-width chrome steel front bumper and a new family of 17-, 18- and 20-inch wheels. It’s beneath the skin, however, where they are truly separated from their predecessors – and the competition.

“GMC has been one of the industry’s strongest truck brands for more than 100 years, and we back the 2011 Sierra HDs with a comprehensive five-year/100,000-mile powertrain warranty that provides the best coverage in America,” said Hutchinson. “From greater diesel power to the segment-best warranty, these trucks deliver strength and peace of mind on all fronts.”

Greater Capability

“You can see by the ratings numbers that the Sierra HD lineup is more capable, but the trucks are also better performers in the intangible qualities that bond owners with their trucks,” said Rick Spina, vehicle line executive. “They accelerate quicker – especially when fully loaded – stop more confidently and deliver a smooth, quiet driving experience that you have to experience to fully appreciate.”

Eleven all-new, fully boxed frame assemblies improve durability and ride characteristics; and support increased capabilities.

The frames have increased cross sections and use more high-strength steel for greater durability, higher towing capacity and improved ride and handling; the front sections are hydroformed. The bending and beaming stiffness of the frames is increased 92 percent and 20 percent, respectively, with the fully boxed sections enhancing torsional stiffness by a factor of five. Also, larger engine and transmission mounts, coupled with a 125-percent-stiffer front frame structure, provide greater vibration control, while hydraulic body mounts are incorporated under the cab section on extended and crew cab models for a more isolated feel inside.

Engineers addressed common customer and aftermarket uses when designing the new frames, including adding access holes to the rear frame section to enable easier installation of fifth-wheel/gooseneck-style hitches. Also, the frame-mounted hitch for conventional trailering is stronger, with a box-tube design. It supports up to 17,000 pounds (7,711 kg).

New, stronger front suspension enables snow plow installation on all 4WD models.

A completely redesigned independent front suspension system offers up to a 25-percent greater front axle weight rating – up to 6,000 pounds (2,721 kg) front gross axle weight rating (FGAWR) – so a snow plow can be used on all 4WD cab configurations with the available snow plow prep package. Sierra’s signature short-long arm/torsion bar front suspension design is retained, but now features new, forged steel upper control arms that are stronger and lighter than their predecessors.

The new lower control arms are made of precision-machined cast iron to handle the greater loads. Five different torsion bar rates support five different front gross axle weight ratings (a single torsion bar was previously used for all models). This helps stabilize the range of trim heights of various models under load, while enhancing appearance, handling, durability, tire wear and alignment. The trim height is adjusted on each bar via a single bolt, easily allowing the height to be changed to account for the weight of a snow plow or other accessories.

The Sierra HD front suspension now uses a pair of urethane jounce bumpers on each side, instead of one, for improved load management; and there’s a new upper shock mount attachment design that’s positively connected to the frame with two fasteners. This design eliminates squeaks and clunks, while supporting higher load capability and increased durability.

Compared to competitors’ beam-axle front suspensions, the Sierra’s independent front suspension provides a better ride, more accurate trim height control (with fewer parts) and greater flexibility to adjust the alignment for weight and tire sensitivity.

New, asymmetrical leaf-spring rear suspension supports greater loads.

Matching the Sierra HD’s greater strength and capability is a rear suspension designed to support greater loads. It features a new, larger asymmetrical leaf-spring design that also contributes to improved ride and handling characteristics. The asymmetrical design is derived from unequal front and rear spring half lengths, which minimize axle hop and enhance traction control efficiency.

The 2500HD models feature a two-stage leaf-spring design, while 3500HD models have a three-stage design. All models feature 3-inch-wide (76 mm) leaf springs that are 20-percent wider than previous models. The larger leaf-spring design supports increased rear gross axle weight ratings across the board. On the 2500HD models, the rating is 6,200 pounds (2,818 kg) – up from 6,084 (2,765). On 3500HD models, the rating increases to 7,050 pounds (3,204 kg) on single-rear-wheel models and 9,375 pounds (4,261 kg) on dual-rear-wheel models – the latter representing a nearly 14-percent increase over the previous 8,200-pound (3,727 kg) rating.

Sierra HDs deliver a more refined driving experience.

Longer wheelbases – ranging from 133.6 inches (3,395 mm) to 167.7 inches (4,259 mm) – and wider front/rear tracks enhance the ride and handling characteristics of the Sierra 2500HD and 3500HD, giving them a greater feeling of smoothness and control. The longer wheelbases and wider tracks are complemented by the new, stiffer frames, new jounce bumpers, shock mounts and hydraulic body mounts to provide a solid, smooth and isolated driving experience. New shocks were specially valved to support the new trucks’ weight ratings, while balancing excellent ride characteristics.

A revised steering system designed to support the trucks’ greater front gross axle weight rating also enhances the driving experience. It includes a new, larger steering gear, power steering pumps and linkages. The pumps (different parts for gas and diesel models) deliver greater pressure for reduced steering effort in low-speed and parking maneuvers; they are also quieter. On some models, the new linkages feature a compliant joint added at the pitman attachment to enhance handling.

New 6.6L Duramax turbo diesel

The workhorse Duramax 6.6L turbo diesel V-8 is more powerful and durable for 2011, delivering 397 horsepower (296 kW) at 3,000 rpm and 765 lb.-ft. of torque (1,037 Nm) at 1,600 rpm. It also produces lower emissions and offers B20 biodiesel capability that promotes a domestically produced renewable fuel.

Sierra HD’s selective catalytic reduction after-treatment system delivers better overall diesel performance, with a range of about 5,000 miles (8,000 km) between DEF refills. Its optimized combustion and after-treatment process provides about 700 miles (1,125 km) between diesel particulate filter regenerations.

New Allison 1000 six-speed automatic transmission

The enhanced Allison 1000 is strengthened to handle the higher torque capability of the new 6.6L Duramax engine, while also helping to improve fuel economy and provide seamless assistance with a new exhaust brake system. Greater efficiency is delivered through reduced “spin loss” – meaning, the transmission channels more of the engine’s power to the axles, allowing it to do more with less fuel.

The Allison 1000 also features driver shift control with tap up/tap down shifting and a patented elevated idle mode cab warm-up feature. Also, the tow/haul mode reduces shift cycling for better control and improved cooling when towing or hauling heavy loads. The six-speed configuration retains its two overdrive gears for optimal efficiency.

Performance with the Duramax/Allison combination is also improved over previous models, with preliminary testing showing 0-60 mph times of less than 9 seconds and quarter-mile times of less than 16 seconds in 2500HD models. That’s about 0.3-second and 0.5-second quicker, respectively, than previous models.

Vortec 6.0L/Hydra-Matic 6L90 six-speed powertrain is standard on all models.

The Vortec 6.0L gas V-8 with variable valve timing returns to the new Sierra HDs, along with a strengthened version of the Hydra-Matic 6L90 six-speed automatic transmission. This combination delivers excellent performance and efficiency, with a greater emphasis on low-rpm power. It is enhanced for 2011 with greater idle refinement.

The engine is rated at 360 horsepower (268 kW) at 5,400 rpm and 380 lb.-ft. (515 Nm) at 4,200 rpm in trucks with GVWRs up to 10,000 pounds. It is rated at an estimated 322 horsepower (240 kW) at 4,400 rpm and 380 lb.-ft. of torque (515 Nm) at 4,200 rpm in trucks with GVWRs greater than 10,000 pounds.

Brake feel and performance is greatly improved.

The standard four-wheel disc system is completely revamped to deliver smoother, more immediate and confident-feeling performance. Four-wheel, four-channel ABS is standard on all single-rear-wheel models and a three-channel system is standard on dual-rear-wheel models. The front and rear rotors are larger in diameter – 14 inches (355 mm) – and width on all models to support their increased capacity, weight ratings and trailering ratings, while the calipers are stiffer and stronger.

The revised hydroboost brake booster calibration reduces pedal effort, and the revised travel of the pedal provides a more comfortable, confident feel. Larger wheel hub and bearing assemblies complement the new brake system, and the rear rotors attach to the wheel hubs for easier servicing.

‘Smart’ exhaust brake provides greater control and reduces brake pad wear.

A new standard feature on Duramax-equipped models is the “smart” exhaust brake. This driver-selectable feature uses the turbine control of the variable geometry turbocharger and the compression of the engine to generate backpressure, slowing the vehicle without applying the brakes. It is integrated with the cruise control feature, and varies the braking to account for the grade and vehicle load. The exhaust brake allows for virtually effortless driving and towing, with seamless and quiet operation. It also helps prolong brake life and prevents overheating the brakes on long, downhill grades.

Safety features include trailer sway control system and hill start assist.

The trailer sway control system provides an added measure of confidence when towing a trailer. The system senses conditions of trailer sway and intervenes with braking and/or reduced engine power to bring the trailer under control and keep it on its intended path. The system uses electric trailer brakes when a trailer is plugged into the standard wiring harness of the truck, and its performance requires no input from the driver.

The hill start assist system is automatically engaged when sensors detect the vehicle is on a grade of about 5 percent or greater. It holds the brakes for about 1.5 seconds or until the gas pedal is pressed, preventing rollback. It is particularly effective when towing, giving the driver time to switch from the brake pedal to the gas pedal without rolling.

Broad lineup – inside and out.

For 2011, the Sierra heavy-duty lineup expands to include 12 2500HD models and nine single- and dual-rear-wheel 3500HD models – including a new 3500HD Crew Cab with a 6.5-foot cargo box. Other models are offered in WT, SLE and SLT trim levels, while popular features such as the EZ Lift tailgate and rearview camera system are retained.

The interiors have excellent attention to detail and are quieter – thanks to the range of the truck’s enhancements. The stronger chassis, quieter Duramax engine and even details like a quieter power steering pump contribute to the Sierra HD delivering exceptional quietness.

Along with quietness, Sierra HD models are designed for work. The interiors feature numerous storage compartments, providing covered access for everything from work gloves to laptops. For those who use their truck as a mobile office, Sierra HDs deliver with available mobile WiFi, USB connectivity, Bluetooth connectivity, XM Satellite Radio and a navigation system. Multiple charge points enable multiple electronic devices to operate simultaneously; and when equipped with the available navigation system, XM NavTraffic offers real-time updates of traffic conditions (in selected areas) that can help plan the most effective route to the job site.

Ready for the long haul – and the cold.

The 2011 Sierra HDs drive farther without stopping to refuel. A new, 36-gallon (136 L) fuel tank is standard on all models and, with the improved fuel efficiency of the powertrains, enables a cruising range of about 680 miles (1,090 km) with the Duramax 6.6L. Cold-weather customers will appreciate the Duramax 6.6L’s quick, reliable start-up, with a starting time on par with gas engines. Its glow plug cycle time is the segment’s best in all temperatures, taking no more than 3 seconds in temperatures as low as -20 F (-29 C). There’s also a cab heat-up feature that allows the engine to idle faster in low temperatures to warm the interior more quickly.

The best warranty coverage in America.

All 2011 Sierra 2500HD and 3500HD trucks work under the best warranty coverage in America: a five-year/100,000-mile limited powertrain warranty, plus roadside assistance, courtesy transportation and other features that provide assurance that GMC backs its trucks for everything the road offers.
