Performance has always been the hallmark of the Infiniti FX – both acceleration and braking, along with tight, responsive handling. The Infiniti FX50 model features a standard 5.0-liter V8 engine design rated at 390 horsepower and 369 lb-ft of torque. One of the keys to the V8’s impressive performance is the adoption of Infiniti’s patented Variable Valve Event & Lift (VVEL) valve control technology, which was first introduced on the high-performance Infiniti G37 Coupe. The VVEL system continuously adjusts valve event and lift amounts, enabling higher fuel efficiency with higher torque and improved emissions over conventional variable valve designs. The VVEL intake camshafts, which feature continuously variable lift control teamed with a Continuously Variable Valve Timing Control System (CVTCS), allow for a 6,800 rpm redline.
Also offered is an advanced 3.5-liter DOHC 24-valve V6, available on FX35 models. The V6 engine features an aluminum block and heads and electronically controlled throttle system and has been tuned specifically for use in the FX35. The engine is rated at 303-horsepower at 6,800 rpm and 262 lb-ft of torque.
The advanced V6 design also features a symmetric twin ram air intake system that reduces airflow resistance, Continuously Variable Valve Timing Control System (CVTCS), a silent timing chain for quiet operation, microfinished crank journals and cam lobes, and Teflon-coated lightweight pistons, a dual exhaust system with equal length exhaust manifolds and low muffler exhaust pressure to help improve engine breathing.

Only one transmission is offered on the 2010 FX – a refined 7-speed transmission that offers both a wide ratio of coverage and a wide lock-up area, as well as a manual shift mode, Downshift Rev Matching and Adaptive Shift Control (ASC). The standard ASC system adapts the transmission’s shift timing, depending on driving style, ensuring more responsive performance. ASC can switch between several different programs – adjusting gear hold and downshifting, helping the FX feel more like a manual shift transmission when desired.
Solid-magnesium paddle shifters (available with the FX50 Sport Package) enable drivers to shift the transmission without releasing their hands from the steering wheel, helping maintain stability for the driver when accelerating or decelerating on winding roads. Infiniti’s advanced Vehicle Dynamic Control (VDC) system with Traction Control System (TCS) is standard on all FX models.
FX50 AWD and FX35 AWD models are equipped with Infiniti’s advanced ATTESA E-TS™ (Advanced Total Traction Engineering System for All Electronic Torque Split) all-wheel drive system, which uses an advanced torque split control strategy that automatically redistributes torque to the wheels (0:100 up to 50:50 front to rear) according to road and driving conditions.
FX offers independent suspension at all four corners, with a double-wishbone suspension design in front and a multi-link design in the rear. Large diameter stabilizer bars are utilized at both ends.
The suspension system also incorporates special Dual Flow Path™ shock absorber technology with rebound springs for responsive yet comfortable ride and firm, tight handling. An available Continuous Damping Control (CDC)® suspension system offers special electronically controlled shock absorbers. Using input from a variety of sensors, the system continuously alters the damping of the shocks to provide optimal ride and handling. A driver-selectable switch with two settings, “Auto” and “Sport,” allows the driver to chose the desired damping mode.
The FX50 is available with an advanced Rear Active Steer system – the first of its kind available in an SUV, which uses precise, electronic motor-driven control to turn the rear wheels up to one degree, helping generate a nimble steering response at low speeds and enhance stability at high speeds.
Secure braking performance is provided by the FX’s 4-wheel ventilated disc brakes with Brake Assist (BA) and Electronic Brake force Distribution (EBD). The FX50 system includes 4-piston front/2-piston rear (opposed piston) calipers and large brake rotors (14.0-inch front/13.8-inch rear).
Superlight six-spoke aluminum-alloy 21-inch wheels, developed by Enkei, are offered as standard equipment on the FX50. They are mounted with 265/45R21 all-season tires. W-rated high-performance summer tires are available as on option with the Sport Package. FX35 models come standard with 18-inch split-5-spoke aluminum-alloy wheels mounted with 265/60R18 all-season tires. The Deluxe Touring Package includes with 20-inch 5-spoke aluminum-alloy wheels with high luster finish and 265/50R20 all-season tires.
Advanced Technology and Safety Systems
The 2010 FX includes an array of available advanced technology systems. The available Intelligent Brake Assist (IBA) system with Forward Collision Warning uses the infrared laser sensor unit from the Intelligent Cruise Control’s (ICC) system and continuously monitors and analyzes closing speeds to a vehicle ahead.
IBA will warn the driver if it determines a frontal collision is imminent. If the driver does not respond to the warning and the collision can no longer be avoided, IBA will automatically engage the brakes to help reduce the impact speed and thus help mitigate the consequences of the accident.
The industry’s first Distance Control Assist (DCA), another available feature on FX, helps reduce the burden of driving by helping the driver maintain a distance to the vehicle ahead in traffic conditions that require frequent braking. Whereas Intelligent Brake Assist is on by default, Distance Control Assist is available at the touch of a button.
DCA is the first system to utilize the accelerator pedal to provide feedback to the driver. If the distance falls below a certain threshold when approaching the preceding vehicle from behind, when the driver releases the accelerator pedal the vehicle will automatically apply the brakes to help maintain distance to the preceding vehicle. If the driver is on the throttle and the system determines that braking may be necessary to avoid the vehicle ahead, DCA will signal to the driver that the throttle should be released by “pushing back” via the accelerator pedal. Initially a subtle push can be felt by the driver as a gentle reminder to maintain a more appropriate distance. If the driver continues closing in on the vehicle ahead, a more insistent double impulse from the pedal plus an audible signal will urge the driver to release the throttle immediately. Upon release of the throttle, DCA will automatically engage the brakes. If necessary, the driver can override the system at any time by depressing the accelerator pedal.
The available Intelligent Cruise Control (Full Speed Range) brings the benefit of cruise control to another level, maintaining a preset distance to the vehicle ahead whether in heavy traffic or on open freeways within a speed range of 0 and 90 mph. ICC can be a stress reliever particularly when driving in congested freeway traffic. The ICC system operates across a wide speed range and helps the driver manage speed and distance down to a complete stop. This allows the FX to flow effortlessly with traffic even at “crawling” speeds and then resume the desired cruising speed once the road opens up again. This helps reduce driver fatigue, especially on long and monotonous commutes, and thus can contribute to a safer driving environment.
Also available on all 2010 FX models is the advanced Infiniti Lane Departure Prevention (LDP) system, which takes Infiniti’s breakthrough Lane Departure Warning system (introduced on the previous generation FX) one step further. If the system senses that the vehicle has drifted toward the edge of its lane, LDP utilizes the FX’s Vehicle Dynamic Control system to gently apply the brakes on the wheels on the opposite side, assisting the driver in returning the vehicle back towards the center of the intended lane.
The Infiniti FX’s Around View Monitor system, first introduced on the Infiniti EX35, utilizes four small superwide-angle cameras – mounted on the front, side and rear of the FX – to provide a virtual 360° view of objects around the vehicle, helping to maneuver it in tight spots. The system uses advanced image processing to combine the images from the four cameras and provide a unique “Birds-Eye View” of the vehicle’s surroundings.
Safety features found on every 2010 FX include a seat belt reminder system; standard Infiniti Advanced Air Bag System (AABS); dual-stage front supplemental air bags with passenger seat occupant classification system and seat belt sensor; seat-mounted side-impact air bags; and roof-mounted curtain air bags for enhanced outboard seat occupant head protection.
Also standard are 3-point front seat belts with pretensioners and load limiters, ALR/ELR seat belts in all passenger seating positions (driver’s side ELR only), adjustable upper anchors, front seat Active Head Restraints, and LATCH (Lower Anchors and Tethers for CHildren) system. A Tire Pressure Monitoring System (TPMS) is also standard.
FX also includes available Front Pre-Crash Seat Belts. Utilizing patented technology (licensed to other automakers), the system automatically retracts some seat belt webbing if the system detects emergency braking or an emergency handling situation. In addition, the FX front seat belts also have a function that automatically self-adjusts the seat belt when buckled to help provide a comfortable and relaxed fit.

"On the road, the FX35 feels lively and peppy, its VQ six-cylinder engine providing its familiar, hard-edged exhaust note to amplify the experience. Far from the growling, sport/ute on steroids experience that is dished out by the clumsy FX50, the 35 feels lighter, more nimble. Power is altogether adequate, even six cylinders make you work a little harder for it than eight do. The FX35 will never win a drag race against its big brother, but damned if it isn’t even more fun with its engine output matched so much more closely to its chassis capabilities. Guiding the FX35 through the hustle and bustle that is L.A. traffic, it almost feels smaller (though it isn’t) and more willing to cut and thrust into lane openings. It is worth noting that we ended up keeping lane-departure and frontal-collision warning systems off, as we found them overly sensitive and, frankly, rather annoying." (MotorTrend)
"On the road, both the V8-powered FX50 and V6-equipped FX35 feel like a handful of other ’utes that are attempting to emphasize the "Sport" in Sport Utility Vehicle. The ride is certainly better than the outgoing FX and even with the dampers set to Sport it’s not the kidney-punishing affair we previously endured. The steering isn’t what we’d call engaging, but it’s what we’ve come to expect from vehicles of this size and weight. Power from the V6 is ample, with a linear torque band that seems to come into its own above 2,500 rpm, while the V8 produces a muted burble out back and provides plenty of motivation when you stamp down on the aluminum long pedal. Both engines have their strong points, but given the weight penalty of the V8 and the better fuel mileage of the V6 (16/21 city/highway for the V6 versus 14/20 for the V8), most buyers would be content with an FX35 optioned up to suit their own specs." (AutoBlog)
"Even on a winding and dipping narrow country lane it’s possible to keep up an impressive head of steam, without having to wrestle with car. Although it doesn’t step off instantaneously, this is a very quick machine and it can carry the speed in challenging conditions mostly thanks to the really excellent body control and accurate, well-weighted, steering. It’s extremely well-balanced on the most laterally undulating roads and has a remarkably good ride on the standard-issue 21-inch wheels, for which we should partly thank the highly impressive Continuous Damping Control. The FX’s appetite for back roads was not just measured by the driver’s sense of progress, the stopwatch backed up the car’s ground-covering abilities." (AutoCar)

The Infiniti FX is a sporty SUV without even trying: it just feels natural! It has an aggressive look and thanks to a balanced ride comfort and a taut suspension the crossover seems to be the right choice. But despite the fact that it handles like a sporty sedan, the FX is a crossover without cargo space. It comes loaded with standard equipment, but this also means that the FX offers less cargo room and versatility than most other midsize crossovers.
But for those looking for a car with a distinctive style and also a stylish, energetic alternative to a typical bland crossover SUV, the Infiniti FX is a must see!
