Model Overview:

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.

  • Fun and Valuable - 2012 Infiniti G Sedan
    By -

    Very fun car to drive. Much better value than BMW, Mercedes, and Audi. People may say this car has road noise, but it is because of the OEM tires. Replace them right away. What is great about this car over its competitors is that it is not numb. You can tell details of the surface the car is on. You can feel it in the wheel and pedals. You don't want a car that is numb (BMW, Lexus etc.), unless you are driving in the city a lot, in which it's pointless to have a 3.7L V6 engine. So, the transmission isn't super smooth and F1-like in it's shifting speed. I like to feel when the car shifts. The G is a higher performing Maxima that looks better.

  • G37X so far so good - 2011 Infiniti G Sedan
    By -

    I just purchased my G37X two weeks ago (previously owned an Audi A4). The G37 really moves! I love driving it and have to fight the temptation to step on the gas. Handling is excellent (ride is firm, as expected). I picked the G37 over another A4 because of 1) performance, and 2) I am hoping that the Infiniti will require fewer repairs than the A4. With that said, I learned that the cost of scheduled maintenance (vs repairs) is not cheap for the Infiniti. Ask the Dealer about this before you buy. Overall, at this point I am very happy that I bought the G37 and I hope that I feel the same a year from now!

  • Great Car to Lease - 2012 Infiniti G Sedan
    By -

    Amazing lease deals on G25x. Got a 2012 for 1300 down and 335 a month incl tax. That's amazing for a luxury car! Can't even get a v6 Camry or accord for that. Decent power, good mpg, awd! Very nice interior and controls. Handles like a dream. Seats too small, not enough thigh support.

  • G25 Sedan: a devil in disguise? - 2011 Infiniti G Sedan
    By -

    I bought my G25 sedan almost a year ago with 26k. Within a week, had to take it to the dealer for condensation in one of the headlights. The dealer replaced it, covered under warranty. Now just within the past month, I've had to bring it back to the dealer twice. Once for the chrome trim peeling on the center console lid and then again for a rattle in the dash/ rattle in front passenger door and broken cupholder. Once again, the dealer did all work covered under warranty. Normally I would be just disgusted with a car that gave me these build quality issues, but for some reason I seem to fall in love with my G all over again every time I get it back from being in the new Q50 service loaner!!

  • Love this car - 2011 Infiniti G Sedan
    By -

    Got this car a few weeks ago and I'm really impressed with the quality. Steering and handling are excellent. The 218 hp engine is adequate enough however it is noisy when accelerating. I feel the exterior is a little boxy looking however I had the dealership add a painted pinstripe which was on the showroom model and it seems to help the appearance in my opinion (just a matter of taste I guess). I like the unique color called 'Blue Slate' which is a combination of blue/grey depending on the light of day. The standard '6' speaker sound system is fine. The interior is first rate and mine had come with the dealer installed wood trim rather than the aluminum which I found added a richness to it.

  • Exellent chasis, confused powertrain - 2011 Infiniti G Sedan
    By -

    I have the regualr, non-sport G37 with stick 17 wheels, and the car is still very sporty, very neutral. At the same time the ride is well composed and smooth. Interior quality is good but not great. Its about on par with my VW GTI in terms material quality for the dash and all the nobs. The fake wood ook good but I've seen better. Leather is fine, but again not the best. Layout is very logical though. Interior room is also fine, but a little less that I expected for a vehicle this size. Considering the my other car, a VW GTI, which is some 20 in shorter has nearly as much front and backseat room... I will describe the power-train in suggested improvements page.

  • Fast, fun, sporty... - 2013 Infiniti G Sedan
    By -

    I'v had the G37 sport sedan for a year now I have to say this car handles very well. It is a bit firm on the road and that's expected with the sport suspension. The 6 speed shifts are smooth but first gear is quicker then most 6 speeds I've driven. Power is quick and on tap. Navigation works well and the interface is easy and Infiniti did a great job of allowing voice, steering wheel control, dash control and touch screen on every component of the media and navigation for connivence. This is not a car you buy unless you plan on being at the pump. I mainly drive to work and back and the occasional windy road trip but not good for long trips with 17 mpg.

  • G25x Nice Surprise - 2011 Infiniti G Sedan
    By -

    After having owned many Audis over the last 15 yrs, I must say that I was pleasantly surprised with Infiniti. The features, handling, dealer service, built quality is awesome. I haven't had the chance to really test the car car as it is still in its break in period. The car handles great, solid, top notch leather, and stereo. I don't miss the VW/Audi dealership service. I expect to make a lot less trips to the dealership.

  • Can't beat the value for the price - 2011 Infiniti G Sedan
    By -

    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 buyer's 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 -

    Once a very good car minus the gas mileage. I've 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 it's 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.
