Overview
Infiniti launched the first-generation FX in 2003 with the introduction of the FX45. The innovative 4-door entered an SUV segment crowded with traditional boxy truck-like offerings. The unveiled Infiniti FX looked more like an auto show concept car than a production vehicle. Under the skin, it shared Nissan's FM (Front Midship) platform with the G Sedan and G coupe, giving it sports-car-like handling, according to the manufacturer. Under the hood, a V-8 engine borrowed from the flagship Q45 sedan gave it the power of a muscle car. Arriving in showrooms, it was joined by its sibling, a 6-cylinder FX35 model. Over the years, Infiniti updated the FX platform with leading-edge technology such as the first-of-its-kind Lane Departure Warning (LDW) system. In 2006, the FX received a significant facelift on both the interior and exterior. The all-new, second-generation Infiniti FX, once again based on the FM platform, debuted at the 2008 Geneva Motor Show. More upscale and luxurious than ever before, the next-generation FX featured an all-new, 5.0-liter V-8 powerplant and an upgraded 3.5-liter V-6 engine. It arrived in showrooms in the fall of 2008 as a 2009 model.

All 2009 Infiniti FX models are offered with a 4-year/60,000-mile basic coverage warranty, and 6-year/70,000-mile powertrain coverage. Infiniti Roadside Assistance is standard during the first four years of ownership.

Model Lineup
Infiniti is offering three different models of the FX for 2009. The flagship of the lineup is the 8-cylinder FX50 AWD (all-wheel drive). The two other models share an identical chassis, but are powered by a smaller and more efficient 6-cylinder engine. These are designated the FX35 RWD (rear-wheel drive) and FX35 AWD. The V-6 powerplant is nearly identical to the 3.5-liter powerplant used in the Infiniti EX35 and Infiniti M35 models.

According to Infiniti, the all-new FX is a "fusion of luxury, performance and SUV utility, with head-turning styling and an advanced sporty platform. It is a showcase of Infiniti's design and technology leadership." As such, each model offers a high level of standard equipment including Infiniti Intelligent key (keyless entry), leather-appointed seating surfaces, 8-way power-adjustable front seats with lumbar support, leather-wrapped steering wheel, and a 300-watt, 11-speaker Bose AM/FM/MP3/CD audio package with dual subwoofers. XM satellite radio is also standard (subscription required).Major option packages (each model specific) include the Sport package with adaptive front lighting (AFS), rear active steer, and Continuous Damping Control (CDC) suspension. The available Navigation package adds the Infiniti Hard Drive (HDD) Navigation System, Around View Monitor (AVM), voice recognition for the HVAC system, XM NavTraffic, 9.3-gigabyte music box, and an 8-inch color display. The Premium package for FX35 models includes climate-controlled front seats, Bluetooth hands-free phone communication, iPod interface, 2-position driver memory seat, and more. The Technology package adds Lane Departure Prevention (LDP) and Lane Departure Warning (LDW) systems; Intelligent Cruise Control (Full Speed Range); Front Pre-Crash Seat Belts; Distance Control Assist (DCA); Intelligent Brake Assist (IBA); and rain-sensing front wipers. Other stand-alone options include the DVD Mobile Entertainment System, and the Deluxe Touring package with 20-inch aluminum wheels (21-inch wheels with summer tires are optional on the FX50).

Powertrain
Infiniti equips the 2009 FX with two different engines. Under the hood of the FX50 is an all-new, 5.0-liter V-8 engine that is more powerful than its 4.5-liter predecessor. The 32-valve engine is rated at 390 hp and 369 lb.-ft. of torque. Power is sent to all four wheels through a standard full-time AWD powertrain (a variant of Nissan's ATTESA E-TS) coupeed to a 7-speed automatic transmission with adaptive shift control. The EPA has rated the fuel economy of the FX50 AWD at 14 mpg city and 20 mpg highway. The FX35 RWD and FX35 AWD both share the same 3.5-liter V-6 engine and are fitted with the same 7-speed transmission as found in the top-of-the-line FX50. The 24-valve engine is rated at 303 hp and 262 lb.-ft. of torque. While the FX35 RWD is rear-wheel drive only, the FX35 AWD is equipped with an advanced, full-time all-wheel-drive system (again shared with the FX50). The 2009 EPA fuel-economy estimates for the FX35 RWD are 16 mpg city and 23 mpg highway.

The second-generation FX rides on a modified derivative of the FM platform shared with the Infiniti G37 sedan. This new platform features a double-wishbone suspension with Continuous Damping Control (CDC) and Rear-Active Steer. Aluminum alloy has been used extensively throughout the suspension to save weight, improve ride quality, and increase responsiveness, Nissan says. The FX35 rides on 18-inch, split 5-spoke wheels with all-season tires; 20-inch wheels are optional. Standard on the FX50 are 21-inch, cast super-lightweight aluminum wheels designed by Enkei. Front and rear brakes are ventilated discs (oversized on the FX50 model). A 4-channel anti-lock braking system (ABS) is standard on all models.

Safety
In addition to advanced Zone Body Construction with front and rear crumple zones, Infiniti has equipped all models in the 2009 FX lineup with six standard air bags, and several active safety features. Infiniti's Advanced Air Bag System (AABS) offers dual-stage supplemental front air bags with seat belt and occupant sensors and side-impact supplemental air bags for both driver and passenger. Front- and rear-seat passengers are protected by a roof-mounted curtain side-impact and rollover supplemental air bag system. Seat belts are equipped with pre-tensioners in all seating positions, and the front seats feature active head restraints to reduce the likelihood of whiplash injuries. A tire-pressure-monitoring system (TPMS) is standard on all 2009 FX models. Infiniti's Lane Departure Prevention System (LDP) is optional on all models. It uses a small camera and microprocessor to watch the road lines and assist the driver in maintaining position within the lane. The standard ABS is fitted with electronic brake-force distribution (EBD) and brake assist (BA). All three systems are designed to help bring the FX to a safe and controlled stop under adverse conditions. Infiniti's traction control system (TCS) and vehicle dynamic control (VDC) are standard on all variants. To simplify infant- and child-seat installation, the Lower Anchors and Tethers for CHildren (LATCH) system is built into the rear outboard seating positions on all 2009 Infiniti FX models.

Although the 2009 Infiniti FX has not been crash tested by the National Highway Traffic Safety Administration (NHTSA), it has been tested by the Insurance Institute for Highway Safety (IIHS). It received a "Good" rating (the Institute's highest) in frontal offset crash testing.
