When it debuted in 2003, the Infiniti FX garnered attention with its bold and sporty look accentuated by large alloy wheels and a sloping rear roofline. Ten years later, the 2013 Infiniti FX offers added power and technology, as well as a more aggressive interpretation of the original's styling.

Though the FX was updated for 2012, the 2013 model arrives with a few changes of its own, including the introduction of a new 325-horsepower FX37 model, which replaces the 303-horsepower FX35. Infiniti has also upgraded the 2013 FX lineup with an available moving-object detection system.

Exterior Features

Infiniti equips the 2013 FX37 with 18-inch alloy wheels, automatic HID headlights, fog lights, LED taillights, power tailgate, and heated power-folding mirrors. Those features are accompanied by a power tilt/slide moonroof, rear spoiler, dual exhaust tips, and rear privacy glass.

Visually, the 2013 Infiniti FX50 is nearly identical to the less powerful FX37, with the exception of 21-inch alloy wheels, aluminum roof rails, and outside mirrors that automatically tilt down when the transmission is shifted into reverse.

In addition to the FX37 and FX50, Infiniti is offering a special 2013 FX Limited Edition model. Only 550 units will be available, all based on the FX37 and upgraded with AWD, Moonlight White exterior paint, reverse tilt-down mirrors, 21-inch alloy wheels and aluminum roof rails sporting a graphite finish, and adaptive auto-leveling HID headlights with smoked lenses.Interior FeaturesDesigners of the 2013 Infiniti FX37 opted to fit the crossover's interior with a generous variety of luxury features, including push-button start, dual-zone climate control, leather upholstery, heated power front seats with 10-way adjustment for the driver and 8-way adjustment for the passenger, and an auto-dimming mirror. The FX37's cabin is also home to black lacquer and stainless steel trim, tilt-and-telescoping steering wheel with integrated audio controls, Bluetooth connectivity, and an 11-speaker premium sound system featuring a USB port and satellite radio service. A large dial, mounted on the instrument panel, is connected to a 7-inch display screen and can be used to control the audio and climate control systems, among other functions.

To that collection of amenities, the 2013 FX50 adds quilted leather upholstery, heated and cooled front seats with memory settings for the driver, wood and aluminum interior trim, in-dash CD/DVD player, Bluetooth streaming audio, and a power tilt-and-telescoping steering wheel. A navigation system is standard, too, and includes an 8-inch touch screen, voice-recognition technology, real-time traffic and weather information, and a 3-D map display.

The FX Limited Edition mimics the FX50 with its aluminum accents, navigation system, driver-side memory settings, power tilt-and-telescoping steering wheel, and Bluetooth streaming audio.

Optional Features

Buyers of the 2013 Infiniti FX37 have their choice of three factory options, one of which is a Deluxe Touring package that consists of 20-inch alloy wheels, wood and aluminum interior trim, cargo cover, quilted leather upholstery, and heated and cooled front seats. A Premium package, also available on the FX37, offers amenities such as the navigation system, reverse tilt-down outside mirrors, in-dash CD/DVD player, driver-side memory settings, and Bluetooth streaming audio. Rounding out the FX37's trio of upgrades is a safety-oriented Technology package, boasting intelligent cruise control, lane-departure prevention and warning systems, forward-collision warning, rain-sensing wipers, adaptive auto-leveling HID headlights, and an intelligent brake assist feature.

Infiniti has reserved a Sport Technology package for the 2013 FX50. Here, the FX37's Technology package is bundled with electronically controlled and continuously adjusted shocks, auto and sport suspension settings, rear steering that turns the wheels up to one degree for improved handling, tinted exterior trim, magnesium paddle shifters, and front sport seats with adjustable bolsters for the driver.

Under the Hood

Like several other 2013 Infiniti models, the FX37 features standard RWD or optional AWD capability and is powered by a 3.7-liter V-6 engine, which, in this application, delivers 325 horsepower and 267 lb.-ft. of torque. Output is managed by a 7-speed automatic transmission that includes a manual mode and downshift rev matching.

For a bit more punch, Infiniti offers the 2013 FX50 with its 5.0-liter V-8 engine that generates 390 horsepower and 369 lb.-ft. of torque. The 7-speed automatic transmission is standard, as is AWD capability.

Fuel Economy

EPA fuel-economy estimates for the 2013 Infiniti FX are:

  • FX37 RWD: 17/24/19 mpg (city/highway/combined)
  • FX37 AWD: 16/22/18 mpg
  • FX50: 14/20/16 mpg


The 2013 Infiniti FX's standard safety features include 6 air bags, traction control, rearview camera, front active head restraints, 4-wheel anti-lock ventilated disc brakes, electronic brake-force distribution, and brake assist. FX50 models add aluminum calipers and larger disc brakes and front and rear park-assist sensors; FX50 and FX Limited Edition models offer a 360-degree exterior camera system that provides a birds-eye view around the crossover, and alerts drivers if a nearby moving object is detected when parking.

In crash tests conducted by the Insurance Institute for Highway Safety (IIHS), the 2013 Infiniti FX received a "Good" rating--the Institute's highest--for moderate frontal-offset crash protection. As this preview is written, the National Highway Traffic Safety Administration (NHTSA) has not rated the crashworthiness of the 2013 Infiniti FX.
