In 2006, the Infiniti Q – Infiniti’s flagship premium luxury sedan – comes with Available Lane Departure Warning and New Sport Model, which continues to push the automotive envelope with a host of innovative features.
The new Sport Model of the Infiniti Q provides a sport-tuned suspension with Rear Active Steer and cast alloy 19-inch wheels and performance tires. The Q45 model is equipped with a revised 5-speed automatic transmission with wider gear spacing, plus Downshift Rev Matching and a new torque converter design for a better shift quality.
A distinctive, premium performance look, which stands out in its class, is also offered by the Infiniti Q . An elegant silhouette, with raised rear deck, large taillights, body-color side molding with accents and chrome door handles are featured by the sculpted profile of the car.
The long wheelbase (113.0 inches) and wide cabin (72.6 inches) give the continuity of the Q45’s dimensions and make its overall length (200.8 inches) still manageable. A high aerodynamic efficiency, with a 0.30 coefficient of drag, is also offered by the Q45.
The large, multi-lens projector High Intensity Discharge (HID) headlight system is one of the most striking features of the Q45’s exterior. To provide a wide distribution beam pattern that uses a large luminous flux, seven individual lenses and a free-surface reflector design are combined.
Highest quality materials with a handcrafted look and a high level of convenience features make the continuity of the Q45’s interior. Rich textured materials, including soft leather appointments and genuine wood accents, cover all the interior surfaces.
The Q45’s cockpit offers the driver a wood-trimmed, leather-wrapped steering wheel, sport contour seats and large, electro-illuminiscent instruments.
A standard DVD-based Infiniti Navigation System with a 7.0-inch LCD screen and a Birdview display LCD monitor is mounted at the highest position on the instrument panel for a better visibility.
With the standard RearView Monitor system, the LCD screen is also used to help view what’s behind the Q45. An image from a small camera mounted near the rear license plate is displayed by the monitor, which operates when the reverse gear is selected. Through the use of colored gridlines, this system indicates the approximate distance to the objects in the camera’s view field behind the car.
The vehicle operation information are displayed by the integrated standard Vehicle Information System (VIS), ranging from audio settings, climate control and maintenance to vehicle settings. Infiniti‘s Voice Recognition System, developed with a second generation Visteon Voice Technology, is another feature found on every Q45. This system offers voice-activated control of the Bose premium audio system, HVAC system and select navigation system functions, allowing the driver’s hands to stay on the wheel at all times.
Standard on all Q45s for 2006 is the Bluetooth Hands-Free Phone System, which allows the user to access phone numbers, answer and make calls through the vehicle’s audio system, keeping the eyes on the road and the hands on the steering wheel.
Among other features of the Q45’s interior, there are an instrument panel with fully integrated switchgear, 10-way driver and 8-way front passenger seat with memory and a dual-zone automatic temperature control system, as well as an Infiniti’s signature in-dash analog clock, which adds an elegant touch to the instrument panel.
A high level of luxury is offered to the rear seat passengers by the ample leg and head room creating a comfortable environment. The sun heat is diminished by an available power rear sun shade, along with manual rear door window sunshades. Also, there are heated power-reclining rear seats with adjustable backrest angle and exit assist, together with an oversize centre armrest with rear audio and climate controls, which provide an exclusive, limousine-like setting for the rear passenger in the Q45 with the Premium Package.
Climate controlled seats in front with ventilated heating and cooling functions, perforated leather-appointed seat inserts and driver lockout for the rear audio and HVAC controls – are also offered by the Premium Package.
Powertrain and Performance
The standard on every Q45 is Infiniti’s 4.5-liter V8, which is also used in the FX45 premium crossover SUV and the Infiniti M45 performance sedan. In the Q45, this engine produces 340 hp and 333 lb-ft of torque.
Titanium valves, modular cylinder heads, microfinished crankshaft, lightweight pistons and a super-silent single stage cam drive chain – all a featured by the Q45’s engine. The V8 is outfitted with a variable length air induction system and Continuously Variable Valve Timing Control System to enhance the engines power delivery and operation efficiency.
Performance and smoothness are optimized by an Electronic Torque-Demand Powertrain Control system, which manages the engine power, throttle positioned and the transmission gear selections. For the 2006 Q45, the transmission has been revised with wider gear spacing and a new torque converter design.
Smoothness, confidence-inspiring handling is provided by the Q45’s rigid body and compliant suspension system – 4-wheel independent suspension with a strut front and multi-link gear.
Safety and Security
The new Infiniti Rear Active Steer system optimizes the handling and stability of the new Q45 Sport. The handling performance is improved by adjusting the rear suspension geometry according to the steering input and vehicle speed.
Four-wheel vented discs with anti-lock function (ABS) provide the Q45’s braking system. This contains two advanced features that help to increase the braking efficiency and control. The Electronic Brake force Distribution (EBD) controls front and rear brake distribution, depending on load condition and the Brake Assist (BA) senses hard or panic pedal application and helps getting maximum braking capacity.
The standard 17-inch aluminum-alloy wheels of the Q45 are finished in a titanium color and offer 225/55R17 V-rated all-season performance tires. The Premium Package includes 8-spoke 18 inch titanium-finish aluminum-alloy wheels with 245/45R18 V-speed rated all-season performance tires. Also available with the Premium Package are 8-spoke 18-inch wheels with chrome finish. A Tire Pressure Monitor System (TPMS) is standard on all Q45s, providing real-time tire pressure readings.
The latest in Infiniti safety technology for 2006, with the available Lane Departure Warning (LDW) system is offered by the Q45. this system recognizes visible lane marking, along with the vehicle speed relative to the marking, generating an audible signal to warn the driver of an imminent lane departure.
An abundance of standard safety features are also included for the Q45, such as patented brake-operated “pre-crash” front seat belts, which tighten under emergency braking to help restrain a passenger before a crash happens. Also, it helps to improve the efficiency of the airbags by reducing the forward movement of the passenger before a crash. If no crash, the pre-crash belts return to the normal mode, ready for the next emergency braking situation.
The safety system of the standard Q45 also includes the Infiniti Advanced Air Bag System (AABS), with passenger seat sensor and dual-stage extra air bags that sense the collision severity and seat belt usage and deploy accordingly. Front seat occupants also get front-seat Active Head Restraints, which help reduce whiplash neck injuries suffered in certain rear-end collisions. Also, supplemental side-impact air bags provide enhanced chest protection and side curtain supplemental air bags that deploy from the roof to protect the heads of both front and outboard rear seat passenger in certain side-impact collisions. The LATCH system and an advanced anti-theft system are included for all Q45s.
