Infiniti rolled out the IPL version of its G37 Convertible at the Los Angeles Auto Show more than a year ago. The Infiniti Performance Line treatment logically mirrors that of the IPL G Coupe, meaning it receives both cosmetic and mechanical tweaks designed to raise the pulse of driving enthusiasts. Aside from the overstated aerodynamic styling components and huge exhaust tips, the cabin features special leather upholstery, aluminum trim and IPL badging to distinguish it from lesser siblings. Under the hood, the 3.7-liter V6 (VQ37VHR) has been recalibrated to deliver 343 horsepower – 18 more than the standard coupe – and 273 pound-feet of torque. The suspension has been upgraded with firmer spring and stabilizer bar rates, multi-piston sport brakes are fitted and 19-inch graphite-finish wheels wrapped with summer rubber are bolted on. There are only two exterior color choices (Moonlight White and Malbec Black) and two upholstery choices (Stone and IPL-exclusive Monaco Red). Everything sounds marvelous until someone reveals its as-tested $62,415 window sticker.

DRIVING NOTES
  • The three-section steel roof raises and lowers in a leisurely manner – give it about 30 seconds each way. While it is marvel to watch, the operation seems clunky, not fluid. Buttoned up, with all four windows closed, the cabin is comfortable. Wind noise is minimal and the front buckets coddle passengers in all the right places. While tight, those of smaller stature will find the two rear seats tolerable for short journeys (my kids never complained). Outward visibility is also very good for a convertible – no impeding B-pillar.
  • Top down driving is pleasant, with wind buffeting minimal even without the optional rear wind deflector (on the window sticker, but missing from my tester). I rolled up the windows, turned the climate-controlled front seats on high, cranked the heater and blasted the impressive 13-speaker Bose audio system. Roofless driving in low 50-degree temperatures was bearable. (Note: When the convertible top is stowed away, the already small trunk is basically nonexistent)
  • Infiniti's IPL-tweaked V6 looks great on paper, but it struggles to move the droptop with real authority. Blame a curb weight of 4,189 pounds – a whopping 400 pounds more than the IPL G Coupe – and a very uncooperative seven-speed automatic transmission. Peak horsepower and torque come late in the power band, yet the slushbox wants to shift early. While things are slightly better in Sport mode, or with the manual magnesium column-mounted paddle shifters, it doesn't feel nearly as quick in real-world driving as its published acceleration times would indicate. My overall average fuel economy was also a less-than-impressive 16.8 mpg.
  • Those goofy cannon-size exhaust tips (each is 4.75-inches across) deliver a drone that becomes downright annoying at some speeds. Even more frustrating, there is noticeable body flex – this is not a very stiff convertible – and minor squeaks and groans become evident when the road turns rough.
  • The upgraded suspension provides a harsh ride, but little else. The Bridgestone Potenza RE050A tires are capable, but when pushed, their narrow front contact patches – only 225/60YR19 – quickly scrubbed in protest of the two-plus tons of mass abusing them. The brakes calipers are beefy, but the street-compound pads don't instill confidence.
  • A high sticker price, middling performance and other small annoyances really work against the Infiniti IPL G Convertible, especially when you consider that the same money will put a base BMW 335is Convertible, Audi S5 Cabriolet or even a Shelby GT500 Convertible in the driveway.

      $62,000? LOL. A CPO E550 Cabrio. , S5, 335, etc are ALL far better options than this. I like Infiniti, but IPL, their pricing, and their ridiculous aftermarket-looking exhaust tips and fascias are out of touch with reality and what consumers want in this caliber of vehicle.

        I agree. This is just about a dull as a performance upgrade can get. M

        This car is a high school boy's fantasy at a wealthy parent's price point. They will sell about 3 units.

      Another perspective - it's about the same money as a ZL1 or GT500 convertible...and an E550 cabrio isn't much more...

      $60+k no thanks and this coming from a G35 owner...i love the car, but i think the base price of $37k is where i'd like to be with this car...add 23k to it and i will tell you it's not worth it, not unless it get the GT-R power-train under that hood can't wait for the new Q50 thought

        Nissan really has lost their sense when it comes to Infiniti prices lately.

      Infiniti just announced a recall on the ILP. Bring car into dealer service. It appears that a twin turbo was not installed at assembly. The turbos will add to the engines horsepower and torque. Expected power numbers should be 450hp and 415 lb ft tq. Infiniti is sorry for this recall.

      Why does Infiniti put the antenna on the trunk like that? It looks terrible. I'm sure they can integrate it some where else on the car. Maybe in the side mirror like in the Corvette? And at that price, as said below, there are a lot of much better options out there. Fail.

      That sticker price would be justified if the exhaust tips were 5" in diameter. I can't believe they want $60k+ for only 4.75" tips!

      Am I the only one surprised with 343hp in an NA V6? Dang. I've not kept up. Torque could be better but wow.

      Personally I am waiting for the $92,000 Sebastian Vettel Edition.

      $61,000? for that i would much rather have an s5 or an e class or even an m3 this to me just looks like $30,000 car.

      Infiniti is starting to step off the reservation a bit. First the absurd new model naming scheme, and now a 2-ton convertible "sports car" that is outrageously expensive. I like Nissan and they have been go-getters over the last decade, but this is absurd, even more so than the Murano Crosscabrio. They should be working on their brand cachet, because there's no way in hell I'm spending $62k - before tax and all the dealer BS - on this thing. This car has no business playing in this price range, and the fact that it's that much heavier now - with no other dynamic elements like engine power increases to compensate - makes it look like a really sorry effort, especially when the M3 can be seen roaming about.

      And next year it will be what? The IPL Q60 C? Who spilled my alphabet cereal?

      A $65,000 car that looks like a $28,000. How brilliant and funny.
