The Infiniti QX is designed with the strength that comes from a clean fluid line that is able to attract and maintain good engine performance. This car has Desai jugam luxurious, open only for driver and passenger in the front, but also for all who are in the car will feel the comfort while driving with this car. Machines used this car is a V8 engine that is powerful and fuel-efficient and available Bodi Motion Control hydraulic system in the engine, thus saving fuel. Infiniti QX designs are inspired and have the technological expertise of previous Infiniti. The Infiniti QX is available in two models, namely the Infiniti QX56 4WD 7-passenger and 8-passenger QX56 4WD.
The second generation of Infiniti QX has been completely redesigned from the platform. The new high-rigidity frame structure improves ride quality by reducing noise, vibration and shock. The new 5.6-liter V8 engine combines the responsive acceleration of Infiniti VVEL (Variable Valve Event and Lift) technology with the efficiency of direct injection gasoline (DIG?) and 7-speed automatic transmission. With 400 hp and 413 Nm of torque, the Infiniti QX manage tasks such as towing boats or trailers (8500 pounds towing capacity), and also offers more than 10% more efficient than the previous generation Infiniti QX.
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 eight adults and their belongings with spacious elegance. The bold front chrome grille is flanked by automatic on/off bi-functional xenon headlights with pop-up headlight washers and integrated front fog lights. Auto-leveling headlights with Adaptive Front lighting System (AFS) are optionally available.
Other exterior features include LED taillights, heated, power-folding sideview mirrors with integrated turn signals, courtesy lights and reverse tilt-down feature, body colour running boards, body colour integrated front and rear splash guards built into the wheel arches, roof rails and crossbars, power sliding tinted glass moonroof and a power rear liftgate.
The new Infiniti QX features revised dimensions versus the previous generation – 1.4-inches (35.56 mm) longer, 1.1-inches (27.94 mm) wider and 3.8-inches (96.52 mm) lower in overall height. A front underbody spoiler, rear liftgate spoiler and redesigned side mirrors help provide improved aerodynamics of 0.37 Cd and zero lift. The Infiniti 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 Durward. “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.
“Customers will never be aware of the extensive efforts taken in the development of the Infiniti QX frame and body to reduce flex, rattles and squeaks – they’ll just enjoy a quiet, comfortable ride that’s unexpected in a full-size SUV,” added Poore. “The new platform can handle family adventures to rugged terrain, without compromising its smooth ride for everyday, around-town cruising.”
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-litre 32-valve DOHC aluminum-alloy V8 features Infiniti’s advanced VVEL (for 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 around 10% versus the 2010 Infiniti QX. Also contributing to the enhanced fuel economy is the 2011 Infiniti QX’s standard 7-speed automatic transmission with Adaptive Shift Control (ASC) and manual shift mode with Downshift Rev Match.
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 Infiniti QX is offered with standard four-wheel drive, 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.
All Infiniti QX models also include Hill Start Assist. With Hill Start Assist, if a driver stops on a slope and steps off the brake pedal, the system will keep the Infiniti QX stationary for a few seconds – with no roll back. This enables drivers to easily switch from the brake pedal to the accelerator on steep inclines.
For the first time ever on an Infiniti vehicle, a new Hydraulic Body Motion Control system is offered (available as part of the Technology Package, which also includes 22-inch wheels and tires and a number of other features). The system helps reduce body lean while turning for a more comfortable ride. Utilizing hydraulic cylinders located at the shock absorbers (connected via cross piping and two accumulators), it adjusts roll stiffness by allowing transfer of fluid between the left and right sides of the vehicle through passive weight transfer during normal driving. It also helps reduce bump shock by setting bounce and roll damping forces separately.
