Really sharp suv

Vehicle: 2006 Infiniti FX45 4dr SUV AWD (4.5L 8cyl 5A)

Great performance SUV. Everyone has their take on the styling, I happen to love it. My wife has a Nissan Maxima and I had a hard time believing that the 3.5 V6 could push this big SUV around, so that's why I went for the FX45. Great power, great torque and I love the engine "note". The SUV really handles very well. The compromise to the styling is a pretty small cargo area. The "stiff ride" everyone talks about works VERY well for me. My Chevy Avalanche felt like I was driving a sofa around corners, the FX45 is very tight, but it's not a cushy ride. So far I love my FX45.

Fun sporty suv

If you are looking for a soft, cushy ride and great gas mileage, this car is not for you. If you are looking for an SUV that drives like a sports car, get an FX45. The FX45 seems similar to the G35 I traded, just higher off the ground and bigger. Ride is a bit bumpy, but that is what you get with an SUV that is built on a sports car platform. The only down side for me is the gas mileage. I have been getting between 15 and 17 mpg around town. I was debating between the 35 and the 45, went with the 45 because it feels "heavier" when you drive it and the gas mileage is about the same (the V8 doesn't have to work as hard). Also looked at BMW and Lexus SUV...the FX45 won me over by far!

Have now put about 15k on my FX45. It is a blast to drive! It corners like a sports car and is very fast. My only suggested change is to offer a softer suspension option. Some people do not like the sports car "feel." You do notice the expansion joints and potholes but no more so than in a Grand Cherokee Overland (my last vehicle). The rear camera is fabulous and the sound system is near perfect. Seats are great and the handling is superb. I have had no mechanical problems at all. Storage space is a little tight for an SUV, but the FX45 is all about driving, not hauling gear. If you love driving but need to carry a load sometimes, this is the vehicle for you. Well done Infiniti!

Love the car - but

Love the car; quick and responsive; good handling; roomy and plenty of head room (husband 6'3"). Love the backup camera. You have to hold on to the steering wheel to drive this car - gets a little tiring.

Fx45 - a very good

Vehicle: 2006 Infiniti FX45 4dr SUV AWD (4.5L 8cyl 5A)

So far I have put 1400 miles on this car. It is a fun to drive car. But initially i did not enjoy it so much, maybe because I have been driving a Toyota Camry V6 for past 10 years and that is a dead silent car which soaks all the potholes in the road. FX45 has very good power and very good handling. Looks are quite aggressive.

It delivers!

Just put on the first 1,000 miles so still not broken in yet. Early impression is that it's deceptively powerful. It cruises just fine, but hit the gas and acceleration is swift and immediate. A nice blend between luxury and sportiness, but leans more towards the sporty side. The manual shift mode is lots of fun. Lots of admiring glances when driving, and the new interior is high quality and comfortable. I like the layout of the controls and color display. My kids like the entertainment system and rear reclining seats. Overall great fit and finish.

What's New for 2006

The new model year brings an exterior refresh to the Infiniti FX45 with a new bumper, grille and wheel design, along with a slightly increased horsepower rating (now 320). New standard features include a rearview monitor, 300-watt Bose audio system and a Bluetooth hands-free system. A new center console design, revised electroluminescent gauges and new aluminum and wood trim finish are also part of the interior changes, while revised suspension tuning helps improve the ride. Finally, the FX45 gains last year's Premium package as standard equipment; it includes a sunroof, auto headlamps, aluminum roof rails, a cargo net and cover, and a universal garage door opener.


So your passions veer toward high-performance sports cars, but family obligations have pushed you toward something larger and more practical. As the automotive industry sees it, you're the target buyer for a crossover SUV. But Infiniti knows that a shapeless jacked-up station wagon won't do it for you. Instead, performance and style must be primary, and they must be sufficiently overwhelming to mask any family-friendly nature. And that's why Infiniti's FX45 has a V8 engine lifted from the Q45 and a curvy body that stands out in a crowd. Like BMW's X5 and Cadillac's SRX, the FX45 aims to please those who seek on-road thrills and, when needed, all-weather capability -- should you feel the desire to scale rocky trails, look elsewhere.

As a bridge between luxury sedans and true SUVs, the FX45 shares a platform with the Infiniti G35, has a four-wheel independent suspension tuned for handling on pavement, and lacks a low-range transfer case. In terms of styling, the FX45's relatively low-slung stance, raised rear deck lid and 20-inch wheels give it a more aggressive look than most other crossover SUVs. Inside, you'll find a spacious five-passenger interior furnished with leather and polished aluminum accents and a central LCD screen. The rear quarters can be equipped with a DVD entertainment system to keep most every rear passenger amused for hours. Cargo capacity is below average for this class, so if serious hauling projects are in the plans, the FX might not be right for you.

Infiniti engineered the FX45 to perform more like a sport sedan than an SUV, and indeed it will have you looking for the scenic route more often than you might think.

Body Styles, Trim Levels, and Options

The FX45 is a midsize crossover SUV offered in one trim level. The long standard features list is highlighted by full leather seating and trim, power 10-way driver and eight-way front passenger seats, dual-zone automatic climate control, heated front seats, HID headlights, a 300-watt Bose audio system, a rearview monitor, 20-inch aluminum wheels and an in-dash six-disc CD changer. Additional standard luxury items include a sunroof, steering wheel audio controls, auto headlights and a programmable universal remote transmitter. Various optional upgrades include a DVD navigation system, intelligent keyless entry that uses electronic signals instead of a conventional keyless remote, a DVD entertainment system, radar-based adaptive cruise control and a tire-pressure monitoring system.

Powertrains and Performance

All FX45s feature a 4.5-liter V8 engine that produces 320 hp. A five-speed automatic transmission with manual-shift capability sends the power to the ground via a standard electronically controlled all-wheel-drive system. Performance is impressive for an SUV, as the FX can accelerate to 60 mph in just 6.5 seconds.


Safety highlights include four-wheel vented disc brakes with ABS, BrakeAssist and Electronic Brakeforce Distribution. Front-seat side-impact airbags are standard, along with front and rear head curtain airbags. Traction and stability control systems also come standard. Infiniti also offers an available Lane Departure Warning System (LDW) that works to alert the driver to any unintended movement of the vehicle out of a designated traffic lane. In NHTSA crash tests, the FX earned five (out of five) stars for its protection of occupants in side impacts. The IIHS gives the FX a "Good" rating (the best rank possible) for protection in frontal offset crashes.

Interior Design and Special Features

With plenty of passenger room and a clean design, the FX's interior is comfortable and welcoming, provided you don't mind its decidedly sporty flavor. The brushed aluminum trim and leather upholstery look great, but there's a bit too much hard plastic for a vehicle in this class. Additionally, the center console has a few too many buttons of similar shape and size. The sloping roofline makes for tight headroom in back, but the seatbacks recline for added space when needed. Poor rear visibility is another consequence of the FX's shape, but the standard rearview monitor compensates by allowing you to see exactly what's behind you while backing up. Cargo room is tight, as there's just 65 cubic feet of capacity compared to 80 cubic feet or more in most midsize SUVs.

Driving Impressions

The 4.5-liter V8 delivers effortless acceleration and a thrilling exhaust note that's unexpected in an SUV. The FX also handles surprisingly well for its size, but the trade-off is a stiff suspension that can be uncomfortable on rough streets. Further, when driven at the upper end of its performance limits, the FX isn't as easy to control as a BMW X5. For a softer ride, consider the FX35 with its smaller wheels and more forgiving setup.
