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.

  I love my new G25 Journey - 2012 Infiniti G Sedan

  Fun to drive upscale sedan - 2011 Infiniti G Sedan
  By joelamp - February 2 - 1:20 am

  Sufficient, though not massive, power from the 218 hp engine. Accelerates briskly, especially in DS or manual mode, but not a land rocket like the G37. EPA rates it only a mile or two per gallon better in fuel economy, but in real life driving I am getting around 24 mpg in the suburbs, while my friends with G37s get around 16-17 mpg. So we are talking around a 7-8 mpg improvement over the G37, which is like a 40-50% improvement. Handles and corners beautifully and is the first car I have owned that is actually fun to drive. Interior and exterior are classy and well designed. Base stereo is fine, dont understand unavailability of Bose upgrade and Navi system. Seats are very comfortable.

  Looks nice but many faults - 2012 Infiniti G Sedan
  By sherm624 - May 21 - 7:11 pm

  We hated this car so much that we returned it 9 months before the end of our lease and paid thousands just to be rid of it. The car looks great but driving is a chore. Steering requires effort, engine noise will wake the dead. Everyone thought the car had an exhaust leak. Transmission is horrible - difficult to launch smooth. Gas mileage is around 22 combined. It misses the mark in luxury by neglecting amenities found in competitors, such as cooled seats, front sensors (only has rear), rain sensing wipers, wood steering wheel. On trips longer than 30 minutes it is not comfortable and the cabin is very cramped. No wonder they stopped making this car.

  Love it! - 2011 Infiniti G Sedan
  By alex1457 - October 19 - 9:25 pm

  My lease was ending on my 08 Sentra and I immediately thought of Infiniti. Went to my dealer and test drove the G35 but it wasnt for me. My salesman then showed me the 25x and that was it. No question! Its doesnt come with Navi but with an iPhone or any smart phone Navi is obsolete. This car is definitely a head turner, love the interior, super comfortable, great back up camera and the dash is awesome. The only thing that I dont like is the loud growl it makes when you take off, its slightly intimidating but then again Ive only had her for a week so Im sure I will get used to it in time. Hate driving in the snow but Im sure this winter I wont mind.

  A Journey of a Thousand Smiles Begins - 2013 Infiniti G Sedan
  By D. Hill - October 18 - 11:53 pm

  I purchased an upscale 2013 Infiniti G37 Journey Sedan about 12 months ago with the Navigation and Premium packages that is a real pleasure to own and drive. Competitive Sports Sedan Cars are appealing and offer options that others wish for, but BMW, Lexus, Audi, or Mercedes-Benz have similar size and features. Edmunds reviews this sedan as a pretty compelling luxury sport sedan, with caveat that up against newer, more recently updated rivals, it isnt as appealing as it once was... I used Edmunds along with other sites to help make the car selection process easy. I sold my 2008 G35X Sedan with options to offset the price at sale. Beyond the personal choices you make, depreciation is the largest TCO driver. So I’d consider the makes, trims and package options, then choose or trade-off to comment on anything that is new and costs over $40K must be questioned as to why you need that or why it matters. The Infiniti Q50 Sedan as new and similarly configured would be at least $5-10K more, but some of the technology was not for me.

  4 Stars for Fun To Drive - 2013 Infiniti G Sedan
  By ELR - July 27 - 9:55 pm

  I got my G37 in December 2013 when dealer had incentives, it is a base Journey with Sunroof. This car is great to drive but there were a few features that it lacked. The 7-speed adaptive transmission was not very solid and had a rough ride to it especially when driving in city streets. The infotainment was very outdated and lacked blue tooth streaming and auxiliary cord (which is a deal-breaker for my next car); these features are standard with the Navigation package. The best part about the car is the Nissan VQ engine. This 3.7 Liter 328hp VQ37VHR naturally aspirated engine is a lot faster than my friends $40k Audi A4.

  I Like It - Very Much - 2011 Infiniti G Sedan
  By yoda4 - February 26 - 10:13 am

  2 months in so far. This car is great. The ride and handling are awesome; the ride is firm but comfortable. Hard core power-heads will want the 3.7L, but I find the 2.5L to offer excellent power. I wish it did not require premium gas. I understand that this allows Nissan to achieve higher peak hp, but the peak hp folks are buying the 3.7L, so... I am not totally blown away by the styling. Other contenders were BMW and Mercedes. I like the looks of both of those better, but horror stories about reliability and repair costs ruled them out. Style is very personal, and many will disagree, but I prefer a more traditional, angular style. Despite that, I bought this car and I am very happy.
