The new Infiniti FX continues with the breathtaking exterior styling and “sports car proportions” that helped the original stand out from all other performance luxury crossovers on the market. The FX blends the substantial lower body of an SUV with the long hood, stretched wheelbase, short front and rear overhangs, low overall height and elegant upper body more commonly found on sports cars – conveying its strong performance personality and breakthrough design architecture at a single glance.
For the new FX generation, distinctive side air vents have been added behind the front wheels. Also, the front wheels have been moved 35 millimeters forward (from the previous generation FX) and the front track has been widened by 50 millimeters – providing an even more pronounced performance stance.
The FX’s design starts with a new front end appearance, led by a lustrous Infiniti signature double-arch front grille, standard fog lamps and Bi-Xenon headlights. The FX50 also includes an automatic-on feature that switches on the headlights automatically on at dusk and a standard Adaptive Front lighting System (AFS). This system automatically controls the lighting pattern and directional aim, based on steering wheel angle and vehicle speed (the headlights can swivel headlights up to 17 degrees).
The FX’s new flat blade windshield wipers and wiper arm design optimize aerodynamic performance – helping improve wiping performance at high speeds and reducing wind noise at high speed. A new rain-sensing feature automatically tunes the wiper pace and speed according to the frequency of the precipitation (as detected by sensors).
The new side air vents are also functional, allowing air to flow from inside the engine compartment to outside the vehicle, reducing high under-hood air pressure. The side vents reduce front end lift by five percent for improved high speed stability.
The Infiniti FX’s aggressive silhouette is highlighted by a strong front-to-rear shoulder line, “taut canopy” greenhouse with chromed window frames, rearward-sloping roofline, integrated rear spoiler and polished roof rails. In the rear, the FX’s simple, bold appearance features LED taillights that extend beyond the body to help create aerodynamic down force and large dual exhaust outlets with chrome finishers.
The FX’s coefficient of drag has been improved to 0.35 from 0.37, with the engineers finessing even the smallest details to help manage airflow, including the front bumper sides, rear spoiler angle and taillight shape.
Under the FX’s polished, assertive styling is an equally advanced body structure. FX utilizes the rigid FM (Front Midship) platform architecture used on the Infiniti G 37, G37 Coupe. The FM platform offers sports car-like front-to-rear weight balance – 54/46 – for exceptional handling.
Additional development was undertaken to reduce weight and enhance body strength. For example, the FX’s aluminum front and rear door panels, which have the same strength and stiffness of conventional steel doors, are 20 kilograms lighter (total for all four doors), allowing the FX to maintain a power-to-weight ratio that is among the best in class. The FX weights 90 kilograms less in body structure weight alone. The new FX’s body is also 1.6 times more resistant to twisting and 3.4 times more resistant to bending than the previous generation FX design.
The new FX utilizes Infiniti’s advanced “Scratch Shield” paint, a special “self-healing” clearcoat paint designed to maintain its gloss-level over time. The paint “repairs” fine scratches, such as fingernail scratches under door handles, restoring the FX’s surface close to its original state. The FX50 is offered in seven exterior colors.
The Infiniti FX’s sporty interior is designed to combine a driver-oriented cockpit/command center with a warm, modern, comfortable passenger environment – all wrapped in rich, natural materials. The high-tech interior design includes an Infiniti signature “double-wave” instrument panel and white-and-violet electroluminescent gauges.
The FX50 comes with a new front sport seat design with an adjustable air-type side support system for added lateral support during “sporty” driving sessions. The driver’s seat features 10-way power-adjustability with lumbar support and a 2-position Driver’s Seat Memory system, while the passenger’s seat is an 8-way power-adjustable design. Covered in a special quilted leather sew pattern, the front sport seats include adjustable thigh extensions, which add an extra level of comfort for drivers and passengers with long legs or for long distance travel. Whereas the front seats include an enhanced climate controlled system with heating and cooling functions for maximum comfort.
Standard on the FX50 is a new Automatic Driving Position System, which moves the seat, steering wheel and outside mirrors adaptively into the correct position. This system allows the driver to change the seat position while driving and keep the same viewpoint and relationship between the steering column and driver’s shoulder position.
The FX interior offers white-and-violet “Fine Vision” electroluminescent gauges with “gear-like” rings on the instrument cluster meters, standard 8.0-inch multi-information display monitor and signature Infiniti analog clock. The center console/shifter area is available in a black quartz finisher or special Curly Maple wood trim, inspired by classical violins, giving a sense of warmth throughout.
The FX interior also offers a leather-wrapped steering wheel and shift knob, along with front door pockets, front seatback pockets, dual front and rear cup holders, locking glove compartment and four assist grips. Other standard equipment includes four 12-volt power outlets, all power windows with one-touch up/down function and power door locks, cargo area tonneau cover and cargo multi partition net, along with aluminum pedals, power tilt and telescoping steering wheel, Infiniti Intelligent Key with push button start and a special 12-point “welcome lighting” system.
The thoughtful design behind the interior of the Infiniti FX extends to the available custom-engineered Bose sound system. The acoustic effect of nearly every interior detail was analyzed. Then, the 11-speaker system was customized for the unique acoustic environment inside the FX. As a result, each listener can enjoy music that approaches the power and emotion of a concert hall performance.”
Occupant comfort takes many forms in the new FX50, including the air that driver and passengers breathe. A standard filter, using fiber impregnated with natural grape seed polyphenol, has the ability to neutralize allergens that conventional filters cannot remove due to their incredibly small size (0.3 to 0.5 microns).
The FX50’s advanced Infiniti Navigation System features a 7-language media display and coverage of more than 30 European countries, along with an advanced RDS-TMC system with real-time traffic information system. A Voice Recognition system comes with the navigation system and includes voice activation for common climate control, navigation, audio system and phone functions.
The 2009 Infiniti FX is offered in three interior color schemes.
