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.

  Excellent Coupe - 2009 Infiniti G37
  By Super car - August 24 - 1:50 am

  Super power comes with AWD. Interior design is excellent. Electronic gadgets are nice to have. This car has a strong engine with all the luxury comfort. It is an excellent coupe that combines both. It is not harsh on the road as BMW. The torque is not there as the 3.35i but still has plenty of power to make you smile.

  Great Car - Better than my 04 - 2008 Infiniti G37
  By tomsim - August 21 - 6:00 pm

  After testing many, many cars to replace my 04 G35 Coupe, I returned to the Infiniti. You cannot beat the combination of performance, quality, style and value in a coupe in this price range. I was a little reluctant to buy the "same" car again but the new one is an upgrade in almost every aspect. Much nicer interior, controls and features. Nicer to drive on everyday basis. Navi system much better than in my Acura TL. Have not had chance to put car to a test yet but seems to have a little better handling than 04 but acceleration about the same. With more torque, this would be a really great performer. Styling classy but understated.

  G37 Journey - fun to drive - 2009 Infiniti G37
  By NatefromWA - August 6 - 1:00 am

  Ive had this car for just over a month and we (my wife and I love it). I had a hard time choosing between the 3 series and the G37 but my wife made the decision easy because she preferred the G37 interior. The navigation and premium package was a must and because we hadnt bought a new car recently, the blue tooth and backup camera were nice features. What got us to the dealership though was predicted RELIABILITY and we chose Infiniti based on my wifes positive experience with Nissan.

  Best sport coupe under $40K, bar none! - 2008 Infiniti G37
  By skim - July 25 - 4:46 am

  This is the best car I have own in my life so far. I test drove BMW 335i prior to this vehicle. Both cars felt very fun to drive. Is BMW worth extra $5K? Definitely NOT. G37s styling looks much sportier than 335i coupe. Redlining at 7500 rpm feels like a true sports car! The sound of the exhaust is truly awesome! I look forward to drive my car after a long hard days work. 19 in rims look great!

  Fantastic Car - 2008 Infiniti G37
  By Brian J - July 10 - 10:00 am

  Ive driven all sorts of sports cars. I was looking for an all around sports car that would get me through a winter as well. This car delivers. Its not going to beat many other sports cars off the line but that mid powerband in the car is wonderful. Steady constant power all the way through the large band. One thing I dont particularly like is the clutch seems a bit mushy. Overall though this is a much sexier car than a 335 by BMW. With the blend of luxury and performance there really isnt anything out there in this price point that competes with it well.

  What An Awesome Car - 2009 Infiniti G37
  By djdminer - July 5 - 9:10 pm

  I absolutely love this vehicle! It is so much fun to drive and for the money is the most powerful coupe you can find at that price.

  A Blast to Drive - 2008 Infiniti G37
  By Dublinguy - June 4 - 7:56 am

  I love this vehicle! It performs as well as a 3 Series BMW, without the extra increase in price that the BMW has. It looks much better than the BMW too! I got the 6MT and the engine feels like it just can keep going with no problem. Beautiful finish and top-notch quality of materials round out an awesome package. My only little quibbles are the lack of more storage space in the center console, and the somewhat thirsty engine coupled with the price of Supreme Unleaded. I was prepared for the fuel economy, so that was not a major problem for me. I add it here as a caution to gas concerned folks. Again for me the major problem is the center console. Otherwise A+++ rating for performance/luxury.

  A great alternative in the rough economy - 2009 Infiniti G37
  By Veggie - May 27 - 5:00 pm

  I wanted something fast, two doors, manual transmission and AWD, and arrived at the Infiniti after eliminating all the competition. Felt like I got 80% of what I wanted, and getting that other 20% would have cost more than double. Even though the Infiniti was the least expensive thing on my list, Im happy with it and have no regrets.

  Compare to others & youll want this G! - 2009 Infiniti G37
  By blnewt - April 11 - 10:36 am

  Just had a 07 G35 and "upgraded" to the 09 G37 & couldnt be happier. The 09 has a bit more acceleration, better hwy MPG and the deals theyre offering its the best bang for the buck in performance sedans right now. The 7 spd Auto in the 09 (compared to the 5 spd in the 07-08) really helps w/ fuel economy. Ive already noticed a 2mpg increase on the hwy and the motor isnt really broken in yet. The 7 spd tends to hunt a bit more for gears in speeds under 30 mph but I know theres a Tech service bulletin to have a trans reflash to smooth the shifts, so thatll be taken care of.

  Love it! - 2008 Infiniti G37
  By sl4y3r - March 28 - 8:25 pm

  I traded my 2009 Nissan Altima 2.5S for a 2008 G37 Coupe because the lack of power it had and it was boring to drive. The G37 Coupe is so fun to drive; especially when merging on the highway >:] With this car car you can pass others cars with ease. The stock exhaust is just amazing when you turn it on and the interior design is really nice as well. The BOSE sound systems is really loud and nice and listening to music on my car is what I love to do (especially when commuting to work). I like the memory seats. Also, I use the iPod integration and use the steering wheel controls and it makes it easy to select songs and the iPod is out of sight the whole time.
