Overview & Reviews

Originally, Infiniti's G sedan was not much more than a humble, rebadged Nissan that got some leather trim and a few extra features to become an Infiniti. It wasn't a convincing luxury car and it was indicative of a brand that didn't know what it was.

Then the G35 came along and not only did Infiniti now have an entry-level model that could take on the world's finest luxury sport sedans, it had a basis for which to establish its brand identity. A fun-to-drive personality, ample high-tech features, eye-catching styling and attractive pricing mark the Infiniti G sedan. As such, it ranks among the best choices in the segment and its long-standing popularity ensures plenty of good prospects for savvy used car shoppers.

Note that this model could potentially carry on with a new name, Q40, in the near future.

Used Infiniti G Sedan Models
The last-generation Infiniti G sedan (the fourth generation) was produced from 2007 through 2013. At first, it was only available as the G35. It then featured a 3.5-liter 306-horsepower V6, usually paired to a five-speed automatic. Trim levels consisted of base, Journey, x (AWD), Sport and Sport 6MT (six-speed manual). We found the latter transmission disappointing, as it was unrefined and sometimes difficult to drive smoothly. Rear-wheel drive was standard, while all-wheel drive was available and indicated with an "x".

The G37 and its accompanying 3.7-liter, 328-hp V6 debuted for 2009, as did a seven-speed automatic that was standard equipment on all but the Sport. The latter again came with a six-speed manual transmission. The following year brought subtle styling tweaks and some new navigation features. Although rare, some G sedans made between 2007 and '09 may have a then-optional four-wheel active steer system (4WAS). Reactions were mixed, though, with several drivers noting diminished steering feedback in so-equipped vehicles.

For 2011, the G25 debuted, offering a less-expensive, lesser-equipped entry into the G family. Produced just two years, the G25 had a 2.5-liter, 218-hp V6 mated to a seven-speed automatic transmission. Buyers had a choice between standard rear-wheel drive and optional all-wheel drive (G25x).

Standard features highlights typically included bi-xenon headlights, keyless ignition and entry, Bluetooth connectivity, power front seats, leather upholstery, heated front seats and automatic climate control. As the years went on, more standard features, such as an iPod/USB audio interface and a rearview camera, were added. Sport trims featured a limited-slip differential, unique 18-inch wheels, summer tires, a sport-tuned suspension, bigger brakes, sport seats and design flourishes. Option highlights included a sunroof, rear parking sensors, a Bose stereo and a navigation system.

Inside the cabin the G boasted 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 Japanese "Shodo-brushstroke finish" aluminum trim (wood trim is optional). The front seats were comfortable and well-bolstered, and the available sport-styled seats offered even more aggressive bolstering, though they could be a bit too snug for larger drivers.

In reviews we found the Infiniti G sedan a well-balanced luxury sport sedan. Although there are plenty of creature comforts, it's the G's dynamic demeanor that has made it a standout among driving enthusiasts. Think of it as a world-class athlete in formal wear. The G's handling was praiseworthy, as it attacked curves with aggression and precision, yet remained poised and compliant when driven over broken pavement. Furthermore, the G37's rapid acceleration was rarely bested in this class.

Overall, any fourth-generation Infiniti G sedan stands shoulder to shoulder with anything in the entry-level luxury segment. Used car shoppers in the market for such a vehicle would be wise to put it at the top of their to-drive list.

The third-generation Infiniti G Sedan was introduced as the G35 and was produced from 2003-'06. It looked similar to its successor, but was more angular and, more notably, had a less luxurious interior with lower-quality materials. A less powerful V6, different chassis tuning and a less stiff structure also make it a less advanced driver's car, but for the time, it was tough to beat and a true performance bargain.

Originally, the G35 was available in one trim level until the all-wheel-drive model arrived for 2004. Its 3.5-liter V6 initially produced 260 hp, but it was bumped to 280 for '05. If you got the manual transmission, it got pumped up to 298. It should be noted, however, that G35s produced for '07 and later have slightly lower horsepower figures, but this was due to a change in SAE testing procedures -- actual output did not change.

Other than the myriad engine changes, there were other noteworthy updates made during this G35's lifetime. It received a new hood, grille, bumpers, side sills and taillights for '05, although it was hardly a revolutionary aesthetic difference. Inside, though, it benefited from a redesigned instrument panel and improved manual transmission with a lower shifting effort. Bluetooth arrived on all Gs for 2006.

In our reviews, we were quite fond of the third-generation Infiniti G. The sedan was a bargain-priced and roomier alternative to the BMW 3 Series. If there was one area of concern, it was the cabin's use of some cheap plastic trim and some unintuitive controls. One feature that was welcome, though, was the optional reclining rear seatbacks, which made it a top choice for backseat comfort.

The first- and second-generation Infiniti G Sedans sold in the 1990s were completely different animals than the subsequent rear-wheel-drive, high-performance breed. These compact, front-wheel-drive models dubbed G20 were unimpressive rebadged Japanese-market Nissans and were produced at a time when Infiniti hadn't established its current knack for creating fun-to-drive, value-oriented luxury sedans.

  Cant beat the value for the price - 2011 Infiniti G Sedan
  By David H - May 8 - 10:00 am

  Just bought this car after test driving the all the competitors in the this segment. I do admit at first i did not think that Infiniti had the cache to compete with BMW, Mercedes, Audi, but after after driving all the aforementioned cars in this class, I kept coming back to the G 37. The power, sportiness, and the ergonomics could not beat for the price. I also test drove the Acura TL and the Lexis IS 350 and still the G 37 stood tall. I am very happy with my purchase. No buyers remorse here. It is a great car with excellent build quality. I know I only had it got 400 miles but I grow more fond of this car with each passing mile that I drive.

  You CAN do better G37 SPORT AUTO - 2013 Infiniti G Sedan
  By blurayking - May 5 - 10:35 am

  Once a very good car minus the gas mileage. Ive had this car for 3 weeks and it averages 20.3 MPG. TERRIBLE! This is my second G Sedan since 2006 and that car got 25 MPG. compared to this one. What went wrong?? I think its their 7 speed transmission. It shifts too many times and NOT smoothly. I drive on the highway 90% of the time. So, it SHOULD by about 26 MPG. Why spend $46,000 for a 2013 G37S?? when there ARE better cars (BMW, Lexus and Audi) out there.

  Infiniti - 2013 Infiniti G Sedan

  Glad I bought the G - 2012 Infiniti G Sedan
  By tkstten - July 3 - 12:00 pm

  So I test drove many vehicles before selecting the G37X with Sport, premium, nav: BMW 3 Series was a great ride, but the RFTs scare me & the value is not great. BMW X3: great ride but I went for smaller. Mercedes GLK: same deal. Volvo S40 was nothing special. The luxury of the G series is pretty outstanding, the handling is on par with BMW 3 series. No complaints at all except MPGs. If I could go back, I would choose the G25 & improve the MPG.

  Wouldve given more stars.... - 2013 Infiniti G Sedan
  By BabNBun - June 26 - 1:46 pm

  I wouldve given more starts if it wasnt for a few things. One major pet peeve is the cup holders. You cannot fit more than one cup in the holders and in the back holders you cant even fit a cup unless it is very small size of a soda can. My second issue is that the seats do not fold down. Every once in awhile I have something large and it will not fit in the trunk and I have to put towels down in the back seat and try to fit items in that way. I wish it had a post to connect my phone to play music. You only have USB ports and no audio plug which the USB ports are a little difficult to get to being within the arm rest. My final complaint is there is a bit of road noise and engine noise that can be heard. Its difficult for others to hear me when on the car Bluetooth due to the noise. Other than these small issues I absolutely love my car. I would consider buying another one if these issues are resolved.

  G37S - Outstanding Value, blast to drive - 2011 Infiniti G Sedan
  By dap2006 - December 22 - 4:24 am

  Having had a 2006 Acura TL and a 2008 Acura TL-S I was ready for a change. While highly reliable, the front wheel drive, rattles, and so-so drive just didnt inspire. Not so with the G37S - drives like a dream, tons of power, top-notch fit and finish - rock solid and ZERO rattles. Buy it and enjoy!

  2nd "G" and Still Loving It... - 2012 Infiniti G Sedan
  By dbalsam - August 26 - 1:18 am

  Prior had 08 G35xS. Bulletproof reliability and loved the car overall. MPGs were not the best and some road/wind noise. Recently stepped into a 12 G37xS. Even though they look similar, a lot of smaller improvements to make car even better. I am also avg. 3mpg better doing same drive. Writing this for anyone looking for a great used car value that appreciates sporty sedan vs. a Camry/Accord. Probably still the best overall value in a 4dr. sports sedan with AWD. Road/Wind noise improved on G37 and much quieter on Hwy. with 7spd auto vs 5spd as engine revs are lower. Suspension seems better over bumps vs. G35 and more solid. Steering lightened up some at low speeds vs. G35.

  Great value - 2013 Infiniti G Sedan
  By Guillermo Pena - August 14 - 11:22 am

  I this is an all round great car. Very quite and comfortable but also really fast when you need it. The all wheel drive X model handles great.

  Our 2nd G from this generation - 2013 Infiniti G Sedan
  By VQd - July 25 - 7:14 am

  I drive an 08 G35xS and my wife needed to replace her Impreza. When comparing against new Mazda 3, Impreza, used Imprezas, it became a no brainer. Used CPO Gs are a bargain. The poor resale value is a bargain price. I work on the guys myself and the build quality of the G is excellent compared to our old Impreza. The review is spot-on. The 07 & 08 Gs were quiet, the later Gs receive bigger pipes for a more noisy exhaust note. I prefer the quietness of the earlier years, but I appreciate the improved fuel efficiency of the 7-speed tranny.

  Forget the GPS - 2012 Infiniti G Sedan
  By mherzen - April 18 - 7:40 pm

  This has good to great handling, very quick acceleration, superb braking. Front seats do not support the hamstring properly, so somewhat uncomfortable. And, the ride is very stiff, so you will feel every bump - not for everyone. My biggest complaint, tho, is the GPS. You pay all this money for this device, you expect it to reliably choose the shortest/best route. This one does not (and I have compared it to others). It frequently gives bogus instructions to change your route, when no such change is necessary or desirable. My complaints to Infiniti have been met with the usual shrug - canned, meaningless responses. My advice: us your cellphone - no map updates needed, & traffic incl
