2009 Infiniti FX50 Review

I lusted after Infiniti’s “Bionic Cheetah” from the moment I saw the renderings in a buff book (remember those?). After climbing behind the wheel of the first-gen FX, I knew that if I ever needed an SUV without cargo space or off-roadabilty, the FX45 was the truck crossover for me. For one thing, it was carved from a block of sex. For another, the stiff-legged handling was righteous. But there's a new sheriff in high center of gravity town: the FX50. Can Infiniti’s new model match the moves, let alone the lines, of it's much admired (by me anyway) predecessor? Well, lemme tell ya…

The FX50’s re-sculpted snout is like Mike Tyson's tattoo. You contemplate it for a second and briefly ratiocinate, “Cool.” One beat later you're wondering, “What in the fuck was he thinking?” From the CUV’s basking shark grill to its squigly lamps, the FX50's prow looks like a weird toad. Fender vents? Why? Thankfully, the FX50’s sheetmetal contains plenty of the previous car's clever cuts and inventive angles, keeping the basic shape solidly in the “Hell yes” column. Especially squatting on those shiny 21” dubs.

Swing open the FX50 door and behold! Infiniti has set a new standard in the all-important wooden door insert competition. The rest of the cabin lives up to the maple-accented portals’ upmarket aspirations, with scads of top shelf soft touch leather and plastic. The FX50’s optional quilted leather seats (with adjustable thigh and back bolstering) are complemented by a steering wheel meaty enough to put off even the most casual vegetarian. The new Fiddy is a lot classier than the last FX, though just as cargo-challenged.

But it’s not short of gadgets. The FX50 packs more electro-wizardry into one space than the Consumer Electronics Show. In front of your left knee: seven buttons labeled with abbreviations like DCA, FCW and IBA. I have no idea what any of them do. But the sheer amount of pressable stuff will impress (and confuse) the Joneses. As for doodads I do understand, the radar-cruise control works so well that I didn’t touch a pedal for over an hour in bumper-to-bumper gridlock. Combine that with Infiniti's beepy Lane Departure Warning system and the FX50 is the first car you can drive from the passenger seat. Blindfolded.

The FX50 is the only Nissan FM chassis variant with the sizzling 5.0-liter V8. That's a shimmering indicator to where Nissan's (and the rest of the industry's) head has been: squarely up their backsides. Still, what a gnarled, snarling brute of an engine. The mighty mill stumps-up 390 horses and 369 torques, making this power-wagon thuggishly quick.

No joke. The brand new lunatic fringe Mitsubishi EVO X with its dual-clutch tranny and cantaloupe-sized turbocharger hits 60 mph in 5.1 seconds. The 4,575 pound FX50 takes one tenth of a second longer. One tenth! The big Infiniti feels much faster than the EVO, and through the quarter-mile — it is! By the time I hit 120 mph it was obvious that the FX50 is a motorized mental case meant for drivers much more psychotic than I. And that’s saying something.

Sadly the transmission sucks. I'm stealing from Berkowitz, but “AUTOCOCKBLOCK!” Under brisk acceleration, the devious seven-speed has you in fifth gear by 30 mph. For the math-averse, that's one shift every six mph. I hate it. True: you can paddle the gears yourself. But it's a slusher, not a dual-clutch. So you're playing the hurry up and wait game. That's hateful, too. If you floor it, the tranny will hold gears up to 7000rpm redline– and the already low mileage will drop off a cliff. The stoppers are mean and mighty, once you get your leg into 'em; the lack of initial bite is disheartening.

Infiniti has revised the FX50’s underpinnings, reducing the travel and heft of the old multilink rear with liberal lashings of aluminum, and fitted double-wishbones up front. Combined with fat, sticky rubber and lots of computerized prestidigitation, the big, tall, portly CUV handles as well as if not better than your sports car. Equally astounding, this time ‘round, your dental fillings are safe.

Unfortunately, tossing the FX50 into a tight corner feels like riding a Macbook. I’m not saying it’s numb, but I would have to drink five Arrogant Bastards to personally achieve the same effect.

So, the new $63k Infiniti FX50 is a ruthlessly fast, lateral-G genius saddled with an electric chastity belt (or three) that’s not very practical and drinks like Charles Bukowski on a bender. Infiniti has crafted a vehicle with all the grace und pace of its German rivals. If you can put up with the numbskull transmission (and insatiable thirst) the FX50 is the fastest, most tossable sedan-on-stilts money can buy. Just don't look it in the eyes.

    I have driven both the FX 35 and the FX 50... while you sacrifice horse power with the 35 you really don't sacrifice features... I really enjoyed the drive, the air conditioned seats and all of the tech gear in the vehicle... while the cameras on the side front and rear are a bit much I found the vehicle to be smoothe and engineered well. it's a solid ride and I would call the FX 50 "The Beast". The front of the car has a look that says "get out of my way or I'll eat your first born child" and I like that in a ride. Slamming the foot down on the gas on the 50 was impressive.... the reviewer in the article didn't care of the trannie of the 50, but that is why they added the triptronic so you can control the shifting without a clutch.

  • 3-On-The-Tree I have a 2009 C6 Corvette LS3 and the only major repair that I have done on it was replace the radiator. Besides usual plugs, wires oil etc. And yes those tires are expensive as well.
  • 28-Cars-Later We had a red 2003 with less than 100 miles in late 2004/5ish and kept it till the end AFAIK. I do recall being told we had about $28,000 in at the time (about $43,6 in 2023 Clown World Bux). I don't ever recall anyone retail even looking at it, and it lived in the showroom/garage."It's an automatic that just had the linkage repaired and upgraded"This really doesn't bode well. Maybe there's a upgrade I'm simply not aware of so one could tune the 3rd Gen LM4 for higher power but messing with it isn't making me smile because now I know its no longer factory or somehow it broke and with such low miles I'm equally concerned.
  • Analoggrotto With Kia Hyundai you are guaranteed to have the best Maintenance and Service experience in the industry. Complementary diagnostics, open book fees schedules and adherence to published rates with no attempts to tack extra work on are part of the HMC Gold Standard of Service. Recalls are the lowest in the industry but when you bring your Hyundai Genesis Kia vehicle in for Feature Improvement, rest assured that it will be taken care of to the highest pentagon standards, fully free of charge with no pressure for paid work or service unless requested. Hyundai Kia have the highest levels of customer ATP loyalty in the industry and Service is key to the best after sales experience.
  • MaintenanceCosts In Toyota's hands, these hybrid powertrains with a single motor and a conventional automatic transmission have not been achieving the same kind of fuel economy benefits as the planetary-gear setups in the smaller cars. It's too bad. Many years ago GM did a group of full-size pickups and SUVs with a 6.0L V8 and a two-motor planetary gear system, and those got the fuel economy boost you'd expect while maintaining big-time towing capacity. Toyota should have done the same with its turbo four and six in the new trucks.
  • JMII My C7 isn't too bad maintain wise but it requires 10 quarts of expensive 0W-40 once a year (per GM) and tires are pricey due size and grip requirements. I average about $600 a year in maintenance but a majority of that is due to track usage. Brake fluid, brake pads and tires add up quickly. Wiper blades, coolant flush, transmission fluid, rear diff fluid and a new battery were the other costs. I bought the car in 2018 with 18k in mileage and now it has 42k. Many of the items mentioned are needed between 20k and 40k per GM's service schedule so my ownership period just happens to align with various intervals.I really need to go thru my service spreadsheet and put track related items on a separate tab to get a better picture of what "normal" cost would be. Its likely 75% of my spend is track related.Repairs to date are only $350. I needed a new XM antenna (aftermarket), a cargo net clip, a backup lamp switch and new LED side markers (aftermarket). The LEDs were the most expensive at $220.
