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.

  Excellent Value - 2011 Infiniti G Sedan
  By Brian B - December 17 - 2:00 am

  Ive had this car for a week and do not regret the purchase. Was wanting a 4 door performance sedan and was considering the Audi S4 but it was $60k after adding the options I wanted. Looked at the G37 and found practically everything I wanted in the S4 for $16k less. Powerful engine, nice interior, and I love the Limited Editions exterior color, Black Malbec, essentially black until you get it in the sunlight where it is dark maroon to purple although the Monacco red leather seats can be polarizing (I love em!). It does seem that I see G37s everywhere though - very popular vehicle. I wish it were a little more "rare" but this vehicle is a great value and a lot of people realize this.

  Poor powertrain - 2011 Infiniti G Sedan
  By ljscap - November 22 - 11:03 am

  The vehicle is solid and handles well. Greatly disappointed in the engine and transmission. Transmission seems to take forever to decide what gear to go into. Gas mileage has averaged 17.2 mpg over the 3500 miles I have driven, half interstate and half suburban. Engine is very weak and combined with the transmission you never know when the acceleration will start. Last three cars were 2008 AUDI A4 Quattro, 2006 BMWX3 and a 2004 Bmw 325i. This Infiniti does not compare at all with the driving pleasure of these cars.

  What a blast! - 2011 Infiniti G Sedan
  By motorman5 - September 26 - 3:30 pm

  This car is really a joy to drive. The handling and power are amazing. While I dont miss winter, I am looking forward to see how it handles in the snow. Interior is great - all the bells and whistles I need. Engine is a little loud at takeoff, but I dont mind - it lets you know its there and sounds like a muscle car. Once youre cruising, its pretty quiet. Got the premium package and Nav system - which is really easy to use and works well. This car is a great value for everything it offers, and I get a lot of compliments.

  G37 2012 Premium & Nav Packages - 2012 Infiniti G Sedan
  By ljpzap - August 8 - 5:32 am

  Great car. Tested IS-250, ES-350, BMW 328i, Acura TL and Maxima. Really depends on what you like. All cars were nice, but G37 was the most fun and overall best to drive. Only down side is yes it is a little small inside if you are in the back seat, but I didnt plan to ride in the back while driving my car. It compares nicely against the 328i and is more bang for the buck. TL came in 2nd for me as it felt just a little too big and bulky when cornering. Stilll a good choice though again depending on the ride you are looking for. Averaging 23.5 in mixed 50/50 driving

  Still in the Honeymoon Phase, but Great So Far - 2011 Infiniti G Sedan
  By dammitjim1 - July 13 - 4:13 pm

  I was in the market for a new car, due to the approaching lease end on my Honda Accord Coupe, which I liked a great deal. Infiniti was not initially at the top of my list. I test drove a near fully loaded G37X near the end of May - Sport, Nav, Premium packages included, and was quite pleasantly surprised at the ride, handling, build quality, and technical sophistication. The dealer made an very aggressive lease offer and I took it. I have the car just about 3 weeks, and am very pleased. Ride, handling, and interior comfort are all just outstanding. The value for the money on the G series sedan is seriously impressive. There are not many other makes can touch Infiniti in this category.

  OMG! LURVE IT=) - 2012 Infiniti G Sedan
  By misspmv - July 7 - 3:43 am

  After 3yrs of pining and researching and pouring over reviews of the Lexus and Audi, my husband suggested this car and the decision was made and purchased within 24 hours. I hadnt considered Infiniti at all but when my husband and I saw the Spring Event Sale, I went the next day to view it. Long story short, I loved it from the start. Its sexy, fast, comfortable, and great buy and the sound system is awesome! My husband now calls me a "Thumper" b/c I all of a sudden like my music with a lot of bumping bass. I got this car for my 40th birthday and I really couldnt be happier! Everyday I fall more in love with this car. The best part is I dont see my car at every turn/light!

  Simply Awesome - 2011 Infiniti G Sedan
  By Keith - February 15 - 2:00 am

  After researching several vehicles, Im very happy with my purchase. This G37X is without a doubt the best vehicle I have driven, so much fun to drive. Its only been a couple of days so far, but there is nothing I dont like about this vehicle. It is very well made, solid, comfortable and fun to drive. If you are thinking about a sports sedan, make sure you check this one out.

  By Sports Car Fan - January 22 - 7:02 pm

  Great performance in a conservative package. Great driving dynamics and loads of power. Exceptional fit and finish with quality material. Great reliability. Driving dynamics are better than he newer and more modern competition made by Infiniti.

  very sure footed - 2012 Infiniti G Sedan
  By stewmeat - November 26 - 9:23 pm

  Pros : power + , bose sysyem with streaming audio , navigation , interior design , price compared to others in its class. Cons : Transmission hesitates or delays , back seat only good for kids , gas milage is just ok Let me start by saying, " this is a nice car" the build quality seems very good. The power is beyond great, and the bose system has a bass filled beat that will keep up with any. You can stream music from your phone without pluging it in (love it) flip through the songs on your phone, look at your address book on the dislay, control it all with your hands on the wheel. Also you can burn your cds or store phone numbers on the built in hard drive.
