What Changed for 2008:

Standard XM satellite radio


The Infinti FX was introduced in 2003. Sharing Nissan’s FM platform with the Infiniti G35 and Nissan 350Z (among others), the 4-door SUV offered sleek concept-car styling and handling that rivaled sports cars, according to the automaker. Consumers were offered a choice between two engines, in 6- or 8-cylinder configurations, and optional ATTESA E-TS all-wheel drive (AWD). Its features and options placed the Infiniti FX against competitors such as the BMW X5.

Porsche Cayenne and Volvo XC90. For 2006, the FX received an extensive facelift that included both interior and exterior updates. Infiniti has added standard XM satellite radio for the 2008 model year.

Model Lineup

The 2008 Infiniti FX is offered in three models: FX35, FX35 AWD and FX45. The two FX35 models feature 6-cylinder power and the choice of rear-wheel drive (RWD) or AWD. The FX45 is only offered with 8-cylinder power and full-time AWD. For 2008, all Infiniti FX models now include standard XM satellite radio.

A leather-appointed interior is standard, as is a 300-watt Bose audio system with 11 speakers, RearView Monitor, 7-inch color display, leather 10-way power driver’s and 8-way power passenger’s seats. Dual-zone automatic climate control, Xenon headlamps, cruise control and split-fold rear seats are also found on all models.

Standard on the FX45 and optional on the FX35 models are three different option packages. The Sport package features larger 20-inch wheels, tinted headlights and lamps, aluminum pedals and etched interior trim. The Hands-Free package adds an Intelligent Key and Bluetooth.

The Touring package includes Infiniti Navigation, lane-departure warning (LDW), and Intelligent Cruise Control and brake assist. The Infiniti navigation system, Run-Flat Tire package and DVD mobile entertainment system are all offered as stand-alone options.

All 2008 Infiniti 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.


The 2008 Infiniti FX is available with two different powerplants. FX35 models feature a 3.5-liter 6-cylinder engine rated at 275 hp and 268 lb.-ft. of torque. The FX35 is RWD with a 5-speed electronically controlled automatic overdrive transmission with a manual shift mode (EPA fuel economy estimates are 15 mpg city/22 mpg highway).

The FX35 AWD features Infiniti’s ATTESA E-TS permanent AWD system mated to the same 5-speed automatic transmission (EPA fuel economy estimates are 15 mpg city/20 mpg highway). The FX45 is powered by a 4.5-liter 8-cylinder engine. It is rated at 320 hp with 335 lb.-ft. of torque.

The only available driveline is permanent ATTESA E-TS AWD mated to the 5-speed automatic transmission (EPA fuel economy estimates are 13 mpg city/17 mpg highway).

All 2008 Infiniti FX models feature a modified version of Nissan’s advanced FM (Front Mid-ship) platform, enhanced for SUV duties. A 4-wheel independent suspension is standard on all models, as are front and rear disc brakes with an anti-lock braking system (ABS). Standard wheels on the FX35 models are 18-inch aluminum alloy, with 20-inch wheels standard on the FX45.


Driver and front passenger in all 2008 Infiniti FX models benefit from the Infiniti Advanced Air Bag System (AABS) including dual-stage front air bags, front-seat-mounted side air bags, and front and rear side curtain air bags (protecting all outboard passengers). Front seat belts are equipped with pre-tensioners and load limiters. Rear seats are fitted with the LATCH (Lower Anchors and Tethers for CHildren) system.

Standard active safety systems on the Infiniti FX models include ABS, Vehicle Dynamic Control (VDC) with traction control (TCS), and a direct-reading tire-pressure-monitoring system. The current-generation Infiniti FX was crash tested by the Insurance Institute for Highway Safety (IIHS ) and earned a frontal offset rating of #34;Good#34;-the highest rating the IIHS offers. The Institute did not report side-impact test results.


The 2008 Infiniti FX35 AWD and FX45 feature Nissan ‘s full-time ATTESA E-TS (Advanced Total Traction Engineering System for All-Electronic Torque Split) AWD system, which is configured with a rear-wheel-drive bias under normal conditions. When the vehicle is in motion, a 16-bit microprocessor monitors ABS sensors for wheel slippage while a G-sensor monitors lateral and longitudinal inputs.

If a loss of traction is sensed, the ECU sends power instantly to the wheels with traction-automatically varying the torque as needed (50:50 up to 0:100). Unlike #34;reactive#34; AWD systems that must wait for a significant loss of traction before responding, the ATTESA E-TS system responds nearly immediately to offer a much smoother transition of power, according to Nissan.
