2008 INFINITI FX Review

KBB Editors

By KBB Editors

Updated January 28, 2025

Our editors drive and evaluate hundreds of new cars every single year, turning thousands of miles and countless hours behind the wheel into helpful reviews, ratings, and comparisons. They also have lives outside of work, or so they think. You’d be surprised what you can learn by hauling a dirt bike, hunting for a wayward sippy cup, or just packing the trunk full of groceries.

Pros

If you love the feel of a sport sedan but need something that can also carry a bit more cargo, offers all-wheel drive and looks likes no other crossover SUV on the planet, the 2008 FX35 and FX45 may very well appeal to you.

Cons

You may not like the FX if you have to carry both cargo and passengers. Some of the FX’s more attractive options are grouped into pricey packages and cannot be ordered separately. And the cost of replacing the huge 18- and 20-inch tires every 30,000 miles will not likely be inexpensive.

What's New?

Major changes for the 2008 FX series include new interior and exterior color combinations and the addition of standard XM Satellite Radio.

Infiniti’s FX35 and FX45 crossover SUVs actually look more like sports cars than light-duty trucks. The racy FX twins definitely stand out in a crowd, but their flashy design sometimes places form over function. The rear hatch opening, for example, is rather small and there is not much cargo space behind the second-row seats. Narrow side glass and a small rear window create large blind spots, although the standard RearView Monitor helps alleviate this concern. If you can live with these minor shortcomings, the 2008 Infiniti FX’s impressive handling and quick acceleration make them the ideal performance crossovers, with expressive exteriors that can definitely turn heads.

2008 INFINITI FX Pricing

2008 INFINITI FX pricing starts at $5,530 for the FX FX35 Sport Utility 4D, which had a starting MSRP of $40,705 when new. The range-topping 2008 FX FX45 Sport Utility 4D starts at $8,044 today, originally priced from $53,055.

The Kelley Blue Book Fair Purchase Price for any individual used vehicle can vary greatly according to mileage, condition, location, and other factors. The prices here reflect what buyers are currently paying for used 2008 INFINITI FX models in typical condition when purchasing from a dealership. These prices are updated weekly.

Driving the INFINITI FX

The 2008 Infiniti FX shares its basic platform with one of Infiniti’s most aggressive performance sedans: The G35. This platform creates a nearly perfect front-to-rear weight ratio that allows the fully independent suspension to work superbly. In the FX45, an enormous set of 20-inch wheels and tires delivers a secure connection to the road. While their grip is not in question, the firm ride of these round rubber giants might be somewhat unsettling. Once under way, the FX’s steering is tight and linear, responding instantly to the driver’s input while the sophisticated suspension keeps the FX nearly level in all but the most extreme cornering maneuvers. The steering can feel a bit heavy due to the large tires, and tight turning circles are not what the FX does best.

Interior Comfort

The FX interior has sort of a cocoon-like atmosphere. The front passengers sit low, and the big dash seems to tower over them. The seats are wonderful, as is the clever motorized instrument cluster that moves with the tilt and telescopic wheel. Rear passengers have plenty of legroom, but may find headroom a bit tight. Cargo space behind the rear seat is minimal, but handy rear-seat levers let you fold the rear seats without having to reach into the cargo hold to release them.}

Exterior Styling

Infiniti describes the FX as a “Bionic Cheetah.” The 20-inch wheels (standard on the FX45) seem enormous given the vehicle’s short wheelbase and, with its short hood and minimal rear overhang, the FX in the side view seems to be all side doors and big wheel wells. The step-in height is low enough that entry and exit are easy, but the squat rear doors require tall passengers to watch their heads.

Favorite Features

RearView Monitor
A rear backup camera allows you to see beyond the narrow rear window.

Interior Colors
The FX’s optional Brick or Espresso leather interiors offer a welcome respite from the usual black, tan and gray.

Standard Features

The 2008 Infiniti FX35’s standard features include a five-speed automatic transmission with manual shift and snow-mode feature, rear-wheel drive, power windows, power locks, heated power mirrors, heated leather seats, dual-zone automatic climate control, four-wheel anti-lock disc brakes (ABS), stability control, fog lights, keyless entry, bi-xenon headlamps, 300-watt 11-speaker Bose audio with iPod accessory and a six-disc MP3-compatible CD changer, XM Satellite Radio, power tilt and telescopic steering wheel, RearView Monitor, 10-way power driver’s seat with power lumbar support and memory, head-curtain and front side-impact airbags, cruise control, 18-inch alloy wheels, traction control and rear wiper. The FX45 adds a 320 horsepower 4.5-liter V8 engine, 20-inch wheels, all-wheel drive, power sunroof, Bluetooth hands-free phone system, automatic headlamps, aluminum roof rails and a Sport suspension.

Factory Options

Options for the FX include all-wheel drive (FX35), Intelligent Key and a rear-seat DVD player. Both models offer a Technology Package that includes DVD navigation, Lane Departure Warning system and Intelligent Cruise Control (requires Hands-Free package which includes Intelligent Key and Bluetooth Hands-Free communication).

Engine & Transmission

The FX35’s 3.5-liter V6 has all the power this vehicle needs and delivers reasonably good fuel economy. The extra cost of the V8 is hard to justify considering you can load the FX35 with every option imaginable for the price of a base FX45.

3.5-liter V6
275 horsepower @ 6200 rpm
268 lb.-ft. of torque @ 4800 rpm
EPA city/highway fuel economy: 15/22 (RWD), 15/20 (AWD)

2008 INFINITI FX Depreciation

Annual Depreciation is an estimation of what your vehicle's value might be over time based on an average of similar vehicles. Estimations are calculated by comparing Kelley Blue Book Private Party Values of vehicles similar to yours over time, as well as forecasts from Manheim Auction data comparing current and projected auction values against current Kelley Blue Book Private Party and Trade-In Values. This is not a guarantee of actual depreciation. Local weather conditions, market factors and driver performance will also impact your vehicle's actual depreciation.
