2008 Infiniti FX Full Review
Date Published: 6/17/08
2008 Infiniti FX Review
The 2008 Infiniti FX carries over with no major changes. FX is a crossover that's available with a V6 or V8 engine. The FX35 teams a 275-hp 3.5-liter V6 engine with rear- or all-wheel drive. FX45 models have a 320-hp 4.5-liter V8 and AWD. Both use a 5-speed automatic transmission. Maximum towing capacity is 3500 lb. Available safety features include ABS, traction control, antiskid system, curtain side airbags, and front side airbags. Infiniti's optional Lane Departure Warning System sounds an alert when the vehicle crosses lane dividers. A sport suspension is standard for FX45, available for FX35. Leather upholstery, heated front seats, power tilt/telescopic steering wheel, driver-seat memory, and a rearview camera are standard. Adaptive cruise control and keyless entry and starting are among available features.

Consumer Guide® Road Test Ratings
Acceleration

AWD FX35 AWD FX35 w/Sport Pkg FX45 w/navigation Class Average
6 6 7 6.1

Among the quicker SUVs. An AWD FX35 did 7.6 sec 0-60 mph in our test; an FX45 did 6.7 sec 0-60. The automatic transmission is smooth but can delay downshifts, making the manual-shift mode attractive for quick passing maneuvers.
Fuel Economy

AWD FX35 AWD FX35 w/Sport Pkg FX45 w/navigation Class Average
3 3 3 3.3

In Consumer Guide testing, AWD FX35s averaged 15.6-16.0 mpg. Test FX45s averaged 14.6-16.0. All require premium-grade gas.
Ride Quality

AWD FX35 AWD FX35 w/Sport Pkg FX45 w/navigation Class Average
4 3 3 5.9

The ride is quite firm even on apparently smooth roads, and it can be harsh over sharp bumps and ridges. FX35 with its standard 18-inch tires cushions impacts far better than models with the sport suspension and 20-inch tires. All exhibit good high-speed stability.
Steering/Handling/Braking

AWD FX35 AWD FX35 w/Sport Pkg FX45 w/navigation Class Average
7 6 6 5.5

FX compensates somewhat for its hard ride by being poised on smooth twisty roads, with great grip and well-checked body lean. Steering is quick and firm with ample feedback that adds to FX's car-like driving feel. Its 20-inch tires tend to follow road grooves, compromising steering control. The sport suspension can jog FX slightly off course in bumpy turns. The brakes erase speed quickly.
Quietness

AWD FX35 AWD FX35 w/Sport Pkg FX45 w/navigation Class Average
6 6 6 6.7

Engine noise intrudes some at full throttle, as does coarse-pavement tire thrum with the 20-inch tires. Neither are annoying, though. Wind rush is modest.
Controls

AWD FX35 AWD FX35 w/Sport Pkg FX45 w/navigation Class Average
7 7 6 6.2

Clear gauges are set in a pod that tilts with the steering wheel. Various buttons and switches abound in the cabin, and they need larger labeling. The navigation system adds controls that further clutter the dashboard, though the system itself is fairly easy to use.
Details

AWD FX35 AWD FX35 w/Sport Pkg FX45 w/navigation Class Average

FX's cabin balances a few low-budget plastic pieces with appealing aluminum trim and good-quality upholstery.
Room/Comfort/Driver Seating (front)

AWD FX35 AWD FX35 w/Sport Pkg FX45 w/navigation Class Average
8 8 8 7.5

Supportive seats bolster well in turns, but they don't provide exceptional leg space even when set fully aft. The available wheel and seat adjustments suit most drivers. Roof styling hampers vision directly aft and over the shoulder. The low roofline requires some ducking upon entry.
Room/Comfort (rear)

AWD FX35 AWD FX35 w/Sport Pkg FX45 w/navigation Class Average
6 6 6 6.5

Too narrow for three adults, but six-footers have decent headroom even beneath the sunroof housing. There's above-average knee space and good under-seat foot clearance. Leg and back support are not the best, despite the presence of reclining seatbacks. Entry and exit demands fancy footwork and twisting to negotiate narrow door bottoms.
Cargo Room

AWD FX35 AWD FX35 w/Sport Pkg FX45 w/navigation Class Average
8 8 8 8.6

Swoopy styling limits height and total volume behind the rear seat, so forget tall or bulky cargo. The load floor is rather high, too. Split rear seatbacks fold easily for extra space. Cabin storage for small items is just okay.
Value within Class

AWD FX35 AWD FX35 w/Sport Pkg FX45 w/navigation Class Average
6 4 5 6.1

FX emphasizes sport over utility, probably too much so for some buyers. But otherworldly styling and sporty road manners help it stand out among premium midsize SUVs. Infiniti's strong warranty and kid-glove customer care are noteworthy, too.

Pricing Key: Retail prices listed with each report are set by the vehicle's manufacturer. These figures appear on each car's federally mandated window sticker. Most price lists also include dealer-invoice prices. Dealer-invoice prices are what the dealer pays the manufacturer for the car and its factory-installed options. The destination charge is not included in the suggested-retail or dealer-invoice price and must be added to the cost of the vehicle. Car companies change prices frequently throughout the year. If the prices published do not match those on the vehicle's window sticker, the manufacturer has probably altered the price recently.
NA = price note available, NC = no charge.

The National Highway Traffic Safety Administration (NHTSA) tests a vehicle's worthiness in front- and side-impact collisions and rates its resistance to rollovers. Front-impact crash-test numbers indicate the chance of serious injury: 5 = 10% or less; 4 = 10-20%; 3 = 20-35%; 2 = 35-45%; 1 = More than 45%. Side-impact crash-test numbers indicate: 5 = 5% or less; 4 = 6-10%; 3 = 11-20%; 2 = 21-25%; 1 = More than 26%. Rollover resistance numbers indicate the chance for rollover when the vehicle leaves the roadway: 5 = Less than 10%; 4 = 10-20%; 3 = 20-30%; 2 = 30-40%; 1 = More than 40%.
