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.

  2 many shortcomings? - 2009 Infiniti G37
  By Steve - October 23 - 5:43 am

  Got this G37 as a less expensive but highly touted alternative to BMW. Driven it 300 miles. Very strong engine & handling and road feel the equal of any BMW 3 or 5. Nav system controls are way too busy & confusing. The show stopper for me is the drivers seat. Good adjustable lumbar support, but very hard bottom to the point of being painful after 30 mins. Driver seat adjustments are also difficult to access & didnt help my 62" frame even though the leg room is very adequate. Good news is that Inifiniti is customer focused & letting me swap the G for the larger M with better seating without penalty. Thanks Infiniti.

  Infiniti Hush Money? - 2009 Infiniti G37
  By bad build quality - October 22 - 5:30 pm

  Right after I purchased a 2009 G37 Convertible, I noticed that there was persistent creaking coming from both sides of the rear portion of the hardtop. That night, I put the top down and up, and noticed that the trunk was opened afterward, so I closed it manually. The next morning, I approached my car in the garage to find the trunk opened again. 2 days later, the engine refused to go past 10 mph and the Engine Light was on so I was forced to bring it into the dealership. Its since been over 30 days and Infiniti has tried to solve the problem twice to no avail. I still dont have my car. Most of all, Im wondering where the other bad reviews are? Can anyone say Infiniti Hush Money?

  Fuel Consumption Terrible - 2009 Infiniti G37
  By Me - December 31 - 3:00 pm

  I have had the car for 1 Week. Fuel consumption is not good at all. I am looking at around 12 miles to the Gallon, have driven 120 miles and used 10 Gallons, this includes a majority of hwy 90 % and 10 % city, my Chevy Tahoe gave me 400+ to a full 20 gallon Gas Tank. I was told that it would give me 17 city and 24 Hwy. It is such an expensive car and I will definitely not buy an infinity again. Very displeased. The car is definitely not worth the money, not much to celebrate for the price payed

  Excellent workmanship. Poor engineering. - 2009 Infiniti G37
  By James C Guess - April 22 - 1:13 am

  Excellent workmanship. Poor engineering. Loud engine and road noises. Bad reflection of dash to windshield from sun and dash lights. Must take vehicle to dealer to check transmission fluid. Vehicle does not track well on straightaway road and requires constant steering. At 70 mph, tach rpm is 2300 whereas, it should be less than 2000 for better mileage. Previous owned Acura TL, type S, a superior vehicle to this one.

  Test drove, dont own - 2008 Infiniti G37
  By IY - April 16 - 3:56 pm

  Coming from 2002 BMW M3 SMG and 2008 Audi A4 6-Speed (GIAC chipped), G37S felt SLOW, maybe just a bit faster then my A4 (again GIAC chipped), and MUCH slower then M3. Steering not as tight as on previous cars, at 28k miles there was a lot of NOT normal wear on plastics and leather. The built quality inside is on par with Honda Civic. I am sorry, I wanted to like this car, but 335i (thats usually compared to G37S) is just a better car all around.
