It starts with a breathtaking presence, a calm strength derived of clean, fluid lines that attract and hold your attention. It continues with the highest level of luxury, not just for the driver and front seat passenger, but all occupants - world class, personalized control over their environments for passengers in every seat in the house. Add in an exceptional driving experience provided by a powerful, yet efficient V8 engine design and available Hydraulic Body Motion Control system. Then top it all off with intuitive functionality, which anticipates and responds to the users’ needs and desires. Introducing the all-new 2011 Infiniti QX, the latest example of inspired design, performance, technology and craftsmanship from Infiniti. Available in two models, the QX56 2WD and QX56 4WD, it is scheduled to go on sale at Infiniti retailers nationwide in summer 2010.

“Following closely on the introduction of the all-new 2011 Infiniti M, the 2011 Infiniti QX gives us an incredible presence in full-size performance luxury vehicles - perfect for buyers seeking style, comfort, roominess and driving exhilaration,” said Ben Poore, vice president, Infiniti Business Unit. “Like the new M, the QX offers a range of available innovative technology, including Blind Spot Warning and an advanced Hydraulic Body Motion Control system.”

The second-generation Infiniti QX56 has been totally redesigned from the platform up. Its new high-stiffness frame structure enhances ride comfort while reducing noise, vibration and harshness. The new 5.6-liter V8 engine combines the responsive acceleration of Infiniti’s VVEL (Variable Valve Event & Lift) technology with the efficiency of Direct Injection Gasoline (DIG) and 7-speed automatic transmission. With 400 horsepower and 413 lb-ft of torque, the QX can handle tasks such as towing boats or trailers (8,500-pound towing capacity, when properly equipped), while also offering 14% better fuel economy (EPA Combined) than the previous generation QX.

Inside the distinctive QX body is an interior long on luxury, including standard Infiniti Hard Drive Navigation System, Around View Monitor, Bose 13-speaker Premium Audio System, available perforated semi-aniline leather seating and an available Tri-Zone Entertainment System with dual 7-inch color monitors, which allows different sources to be played at the same time. The 2011 QX also offers ample 1st row and class-leading 2nd row roominess.

The 2011 Infiniti QX is conceived to attract and hold viewers’ attention, conveying its underlying sense of power and strength. The design is dynamic, its size capable of transporting up to eight adults and their belongings with spacious elegance. The bold front chrome grille is flanked by automatic on/off bi-functional xenon headlights with windshield wiper interlock and integrated front fog lights. Adaptive Front lighting System (AFS) with auto-leveling headlights and headlight washers are also available.

The new QX features revised dimensions versus the previous generation - 1.4-inches longer and 1.1-inches wider. While overall vehicle height has been reduced by 2.0 inches for the 2WD model and 2.9 inches on the 4WD model, interior headroom measurements are virtually unchanged from the previous generation primarily due to the implementation of a more efficient interior overhead trim design. A front underbody spoiler, functional rear liftgate spoiler and redesigned side mirrors help provide aerodynamics of 0.36 Cd and zero lift. The QX’s strong presence is accented by the powerful wheel and tire combinations - standard 20-inch and available 22-inch - and a palette of six distinctive exterior colors.

“The look is clearly Infiniti with its signature Infiniti grille, broad shoulders and large greenhouse,” said Poore. “It’s rugged, sophisticated and completely captivating.”

The 2011 Infiniti QX’s all-new body and frame are designed to provide enhanced body stiffness and reduced vibration versus the previous QX design. Structural changes include a new high-stiffness frame structure with enlarged side rail section width, redesigned connecting structures between each crossmember and side rails, an integrated rear hitch member, improved stiffness of the cabin mounting points and a special rear body ring structure around the tailgate.

The second-generation Infiniti QX also offers new engine and transmission designs - delivering, a combination of power, efficiency and refinement worthy of the Infiniti name. The new 5.6-liter 32-valve DOHC aluminum-alloy V8 features Infiniti’s advanced VVEL (Variable Valve Event & Lift) technology and new Direct Injection Gasoline (DIG) system.

The VVEL system combines hydraulic-controlled variable valve timing and electronically controlled variable valve lift on the intake side to help improve performance and response. Throttle response is enhanced by directly controlling the intake valve, rather than using the traditional method of controlling intake with the throttle valve. The VVEL system also offers improved emissions and fuel efficiency (over non-VVEL designs) by substantially reducing the intake resistance that occurs when the engine’s throttle valve opening is narrowed and output is low. The new DIG system provides better wide-open throttle performance and improved fuel economy and emissions performance by reducing engine knock, improving combustion stability and offering more precise injection control.

The engine is rated at 400 horsepower and 413 lb-ft of torque, compared with 320 horsepower and 393 lb-ft of torque produced by the 2010 QX’s non-VVEL/non-DIG V8. With a 25% increase in horsepower, the 2011 QX does not sacrifice fuel economy, which increases by up to 18% (Highway, versus the 2010 QX) to 14 mpg City, 20 mpg Highway and 16 mpg Combined for both the QX56 2WD and 4WD models.

Also contributing to the enhanced fuel economy is the 2011 QX’s standard 7-speed automatic transmission with Adaptive Shift Control (ASC) and manual shift mode with Downshift Rev Matching (DRM). Versus the 2010 QX’s 5-speed automatic, the new 7-speed transmission boasts a wider range of gear ratios, a variable lockup torque converter, a new improved shift schedule and a new automatic transmission fluid warmer designed to reduce fuel consumption at start up.

The QX is offered in rear-wheel drive and four-wheel drive, with the 4WD model featuring Infiniti’s proven All-Mode 4WD system with Auto, 4H and 4L modes. The system is designed to distribute torque to all four wheels when road conditions warrant (up to 50 percent can go to the front wheels on demand), helping to enhance traction.

A new Hydraulic Body Motion Control system is available on both 2WD and 4WD models as part of the Deluxe Touring Package (which also includes 22-inch wheels and tires and a number of other features). The system helps to reduce body lean in turns, resulting in improved ride comfort for passengers in all three rows. Suspension travel is automatically controlled by hydraulic chambers integrated into each shock absorber. The chambers are cross-linked with piping, allowing for the transfer of hydraulic fluid, managed seamlessly by nitrogen-charged accumulators, from one side of the vehicle to the other. This enables the system to vary suspension travel independently on either side of the vehicle, thereby counteracting body lean and creating a luxurious, flat ride” previously unavailable to drivers in this segment.

Braking is provided by 4-wheel disc brakes (13.8-inch vented discs front and rear) with Anti-lock Braking System (ABS) and Electronic Brake force Distribution (EBD). A new hydraulic brake booster (replacing the previous vacuum booster) helps to generate firm pedal feel with reduced travel, thereby increasing system responsiveness. Vehicle Dynamic Control (VDC) and 2-wheel or 4-wheel Active Brake Limited-Slip (ABLS) are standard on every QX56. Engine-speed-sensitive power steering is also standard.

Every 2011 QX comes with 20-inch, forked 7-spoke aluminum-alloy wheels with P275/60R20 all-season performance tires, while 22-inch, 9-spoke forged aluminum-alloy wheels with P275/50R22 all-season performance tires are included with the Deluxe Touring Package. A Tire Pressure Monitoring System (TPMS) with four-corner pressure readout and Tire Inflation Indicator is also standard.

The new QX’s world-class inner sanctum offers a comfortable space and personal controls for every occupant. It features standard 7-passenger seating capacity, with 8-passenger capacity available with the 2nd row 60/40-split folding bench seat. Leather-appointed seating is standard for all three rows, with even more luxurious semi-aniline leather seating surfaces offered in the Deluxe Touring Package. The driver’s seat is 10-way power adjustable, including 2-way power lumbar support. It features a standard dual occupant memory system for the driver’s seat, steering wheel and outside mirrors. The front passenger’s seat is 8-way power adjustable, including 2-way power lumbar support. Heated front seat are standard, with available climate-controlled (heating and cooling functions) front seats and heated 2nd row seats (outboard positions only when equipped with a bench seat). The 2nd row captain’s chairs offer a tip-up function for easy 3rd row entry/exit.

Among the new QX’s available premium entertainment and technology features are an 8-inch WVGA color touch-screen display, Infiniti Controller for use with vehicle information systems and comfort and convenience features, and the Infiniti Hard Drive Navigation System with XM NavTraffic with Real-Time Traffic Information, XM NavWeather with Real-Time Weather and 3-day forecast (XM subscription required, sold separately) and Zagat Survey Restaurant Guide. Bluetooth Hands-free Phone System is standard, as is the convenient Around View Monitor with Front and Rear Sonar System. The Around View Monitor is standard on the all-new QX - the third Infiniti model to adopt it and first in its segment. The system provides the driver with a virtual 360 view of their vehicle to aid in parking situations. This iteration of Around View Monitor includes a 180 RearView camera mode.

The Bose 13-speaker Premium Audio System includes two subwoofers. Rear headliner-mounted 3rd row speakers ensure that sound quality is not compromised by obstructions such as luggage or cargo. Other standard equipment includes a single in-dash CD/DVD player with MP3 playback, a 9.3GB Music Box hard drive, XM Satellite Radio, USB connection port for use with iPod Interface or other compatible devices and Streaming Audio via Bluetooth.

Like the new 2011 Infiniti M sedan, the new QX offers a range of advanced technology systems. The QX includes both Infiniti’s Lane Departure Warning (LDW) and Lane Departure Prevention (LDP) systems. The LDW and LDP systems use a small camera installed behind the windshield to detect lane markers in front of the vehicle, calculate its position relative to those lane markers and help warn the driver of a potential unintended lane departure with a visual indicator and audible buzzer. If the driver does not return the vehicle back toward the center of the travel lane, the LDP system assists the driver with a gentle application of the brakes on the opposite side of the drift.

Distance Control Assist (DCA), which intuitively prompts the driver to release the throttle and applies the brakes in slowing traffic, is available as part of the Technology Package - along with Intelligent Brake Assist (IBA) with Forward Collision Warning (FCW) and front Pre-Crash Seat Belts.

The 2011 Infiniti QX is available in two well-equipped models: Infiniti QX56 2WD and Infiniti QX56 4WD. Each is equipped with the advanced 5.6-liter V8 and 7-speed automatic transmission and a full range of luxury and performance features including leather-appointed seating, Infiniti Hard Drive Navigation System, Around View Monitor and Bose Premium Audio system.

A number of additional equipment packages are offered, the Deluxe Touring package, the Theater package and the Technology package, allowing buyers to fine-tune their QX experience to their exact needs.
