Overview & Reviews

Nissan launched its upscale Infiniti division in 1989 with two unique models and a polarizing ad campaign. More than two decades later, Infiniti continues to blaze its own trail in pursuit of luxury, performance and style. The Infiniti G37 sport coupe, sedan and convertible are prime examples of this corporate philosophy. Blessed with a split personality, the rear-wheel-drive G37 will deliver you to work in luxury during the week and then clip apexes all weekend without breaking a sweat.

The list of luxury sport coupes and sedans is typically dominated by elite Teutonic nameplates. In readying the G37, Infiniti honed it on test circuits throughout Europe, including Germany's famed Nürburgring. This athletic chassis, along with the G's attractive sticker price, distinctive interior appointments and ample array of technology, makes it well prepared for battle in this class.

Used Infiniti G37 Models
The Infiniti G37 was first introduced as a coupe for 2008, with the convertible arriving the following year. Technically, the G37 sedan arrived for 2009 as well, but it was really the same vehicle as the second-generation G35 sedan that arrived for '07, albeit with a larger 3.7-liter V6. Confused yet? It gets worse. For 2011, Infiniti officially broke these cars apart into separate models, so for information on a new G, please read the Infiniti G Sedan review, Infiniti G Coupe review and Infiniti G Convertible review.

Used Infiniti G37 models are available in coupe, sedan or convertible body styles, with four possible trim levels: base, Journey, G37x and Sport 6MT. The convertible was only offered in base or Sport 6MT trim, though. For 2010, a special range-topping Anniversary model added features that included navigation, an upgraded Bose audio system, iPod connectivity and ventilated seats (for the convertible only).

In addition to the long list of standard features packaged with each trim level, several options, including the Anniversary add-ons were available à la carte. Adaptive cruise control will alleviate some fatigue on long trips, while the available Sport package (standard on the G37 Sport 6MT and optional on the G37 Journey) will rouse the interest of more aggressive drivers thanks to features like a limited-slip differential, a sport-tuned suspension and brakes, sport seats and bigger wheels.

A four-wheel active steer system (4WAS) was available for those obsessed with pushing the technological envelope, but reactions were mixed, with several drivers noting diminished steering feedback in vehicles equipped with 4WAS. It was eliminated after 2009. Stability control, front-seat side airbags and side curtain airbags can be found on all used Infiniti G37s, and a pre-collision preparation feature was optional.

During these years, the G37's 3.7-liter V6 produced a very healthy 330 horsepower and 270 pound-feet of torque, fed to either the rear wheels or all four (G37x). In base, Journey and G37x trims, the G37 came with a seven-speed automatic transmission featuring paddle shifters, while the Sport 6MT featured a six-speed manual. Both transmissions have their devotees, but the clutch take-up in the manual is a little too abrupt. Acceleration and mileage numbers are comparable between the automatic and manual, so the choice is a matter of personal preference.

A used G37 from these years offered user-friendly controls, excellent build quality and a handsome design -- the latter highlighted by such items as the car's leather-accented magnesium transmission paddle shifters and attractive interior trim. The front seats are comfortable and well-bolstered, and the available sport-styled seats offer even more aggressive bolstering, though they may be a bit too snug for larger drivers. Both the sedan and coupe feel like sports cars wrapped in a luxury car package, but the coupe, with seats that are mounted slightly lower than the sedan's, feels a bit racier. We're less enamored with the convertible, as it's less refined and practical than its competitors from those years.

Overall, the Infiniti G37 stands shoulder to shoulder with all its contemporary rivals in the entry-level luxury segment. Used car consumers in the market for such a vehicle would be wise to put it at the top of their to-drive list.

  Love the Car--Hate the Cupholders - 2009 Infiniti G37
  By Ann - January 5 - 1:03 am

  I have had my convertible for over a month. I have been waiting for it since Feb. I LOVE everything about it, except the cuphold situation-- or more accurately, the lack of good cupholders. I ordered the manual version and test drove the automatic. Different cupholders! Also, my average gas mileage is about 17.1 mpg. I would love to get the advertised 19-21mpg. Im still learning all the features to the car, but I am totally enjoying the navigation system and phone/iPod connection. Also, the speakers in the headrest is the best. I will say that the Lexus has more trunk space with the top down than the Infiniti. I only have room for an umbrella and a baseball hat in the trunk.

  Great for empy nesters - 2009 Infiniti G37
  By bburgh - April 3 - 11:08 pm

  If you need a big trunk, plan on having people in the back seat for longer than 1/2 an hour or dont like a sporty ride dont buy this car. For two people who like to throw a car around on country roads this is "the" car. Its a joy to drive hard, but very comfortable if you take it easy. My only problem is my wife keeps taking it.

  Want my 04 G35 Coupe back! - 2009 Infiniti G37
  By Amy - March 21 - 6:26 pm

  Replaced my 04 G35 coupe w/Sport suspension with 09 same pkgs. Just wanted updated electronics. What I loved best about the 04: tight steering, throaty feel and great brakes. Infiniti ruined all three. The steering is loose, the 7 spd transmission spends all its time at high rpms shifting all over the place - like an old 4 cylinder piece of junk and the brakes grind. After 2 weeks and 900 miles, I guess I only have a few more years to hate it. Maybe I can still buy back my 04.

  Good Job Infiniti - 2008 Infiniti G37
  By A.C. Nash, Esq. - March 16 - 5:46 am

  After driving my family and friends crazy over the A5, G37, and 335i I finally bit the bullet and went with my first love. So far it has been a blast. Fun to drive and a real crowd pleaser. I have every option from 4WAS to Tech Pack to Sport Premium etc. Really enjoy starting it and taking off.

  Should have bought the BMW - 2009 Infiniti G37
  By Unhappy G Owner - January 1 - 9:13 am

  Ive had my G37x coupe for about 8 months and I cant believe Im writing a negative review. The car was awesome for the first 10k miles. However, lately its just been one issue after another. I went out to my car this morning and saw rust on the trunk right below the rear spoiler. Yes rust after < 1 year on a car that costs $45k. I couldnt believe it. Well see how the dealer handles it. In additions to the rust, the car has developed multiple squeaks from the center console and right dash area. The ipod connector has begun to randomly show my iphone as disconnected even though its plugged in. The drivers seat is also starting to bubble (common issue)

  G37 2008 - 2008 Infiniti G37
  By OoohYeeaah - August 1 - 11:00 pm

  Have 5K miles and love the car. Hard to see well with the mirrors. Have a big dent in the cool looking aluminum inside door handle where seatbelt flung back and tagged it. Goes fast enough for me. Happy with it. Got a speeding ticket my first month and I wasnt even speeding. Cop had new Dodge Charger interceptor. My first sports car. Wheels get caught in ruts in interstate, and have to constantly readjust when driving. Moving GPS map is very helpful. Cell phone to car interface is way cool, so easy to use. My teenager kids love it too. Dont like speedometer, missing many in between numbers.

  Almost, but not quite - 2008 Infiniti G37
  By Enthusiastic - September 17 - 7:56 am

  Journey with Premium/Nav/Sport. Best value for the money. BMW 335 much more expensive and many features not available on it. Paddle shifting 5 speed isnt great, I leave it in auto. Auto needs at least 6 gears. Great quality seats. Feels slower than my CLS500 but its not broken in yet. Traded my 2004 WRX for it and no regrets at all. Most technically advanced car I have ever driven, executed well, easy to use. Even my wife likes it. Says she gets more looks than when she is driving her G500. I see many G35 coupes on the road, thats a negative. When I first saw the G37 on the road I thought it was a Lexus, good thing. Previous version was too "slab-like". No regrets at all.

  Cant Beat it For The Money - 2008 Infiniti G37
  By Jgoldz - September 16 - 12:20 pm

  As an owner of Acura, Lexus and Mercedes I have to say this trumps all of them in what you get for the money. The car is fast, affordable and fun. Cant beat the two year lease Infiniti usually offers on the car. Other favorite features include attention grabbing looks,and intuitive navi system. However, the build quality could be better on the car, where Ive had a problem with the muffler in the first few thousand miles, although that was only on early models from what Ive heard. Also, I wouldnt label the car a true sports car since in the corners it could be a little more nimble. 3 series beats it in that. Overall, an amazing car and still my realistic dream car that Im so proud to own

  2009 G37 X Review - 2009 Infiniti G37
  By dave - April 18 - 10:53 am

  I test drove TL S-AWD, BMW 335 X drive, and G37 X. BMW 335 gave me the best driving experience in terms of acceleration, handling, brakes, and comfort. G37 was good too but not as good as BMW. I bought the G37 because I got 6 grand off MSRP and its roomier inside. Im sure its a lot more reliable than BMW.

  Not overly impressed for the $$$$ - 2009 Infiniti G37
  By Spike1 - September 7 - 11:40 pm

  Plenty enough power which probably accounts for the less than average advertised fuel economy. Im averaging just about 20mph city&highway without really pushing it. If youre planning on driving it (mine is the x version),in the snow I wouldnt recommend doing it with the factory Dunlop so-called all season tires. They are useless in the snow, and defeat the purpose of the new all wheel drive system. I replaced mine with the new Continental Extreme DWSs, and WOW...what a difference. Unless my car is an exception, be aware that there seems to be a noticeable lag when shifting from the auto to manual mode. Otherwise, for the most part, relatively satisfied so far after 3,000 miles.
