The Infiniti G Sedan lineup for 2013 has been pared down to just three trim levels. The G25 is no longer offered.
By their very nature, luxury sport sedans must have wide-ranging talents. It's not an easy feat for an automaker to pull off, yet the 2013 Infiniti G37 does so sublimely. It is neither a tiresome hard-edged performance sedan nor a soulless techno-puff. Since rising from the ashes in its current front-engine/rear-drive form more than a decade ago, the G sedan has steadily evolved, growing more mature and technologically advanced while also improving in terms of outright performance and value.
Available in only three trim levels this year, the G37 remains highly competitive because it appeals to both driving enthusiasts and luxury-minded drivers. Each trim highlights a particular skill set, yet each offers an engaging driving experience matched by a scant few competitors. The Journey is an invigorating well-equipped base model that is available with numerous options. The Sport model enhances athleticism even further, yet this added control while attacking the corners doesn't come at the cost of a comfortable ride around town. The all-wheel-drive G37x would find good use in wet climes.
This isn't to say that Infiniti is the only one to crack the luxury sport sedan code. The 2013 BMW 3 Series continues to be the standard-bearer in this segment, largely a result of its higher degree of refinement. The 2013 Audi A4 and 2013 Mercedes-Benz C-Class are also very worthy of consideration. Perhaps one of the intangibles will appeal when you select your favorite from this group of cars, but when it comes to simultaneously appealing to the heart and head, the 2013 Infiniti G Sedan is tough to beat.

Body Styles, Trim Levels, and Options
The 2013 Infiniti G sedan is a four-door midsize luxury sedan that seats five. It is available in G37 Journey, G37 Sport and G37x trim levels. The G coupe and convertible models are addressed in separate reviews.
Both the base G37 Journey and all-wheel-drive G37x come standard with 17-inch alloy wheels, automatic xenon headlights, foglights, keyless ignition/entry, cruise control, dual-zone automatic climate control, heated eight-way power front seats, leather upholstery, a tilt-and-telescoping steering wheel, Bluetooth phone connectivity, a 7-inch display monitor, a rearview camera and a six-speaker sound system with a CD player, satellite radio and an iPod/USB audio interface.
The Premium package adds a sunroof, rear parking sensors, driver memory functions, a power tilt-and-telescoping steering wheel and a 10-speaker Bose sound system. The Navigation package adds a navigation system, voice controls and Bluetooth streaming audio.
The above options are standard on the G37 Sport, along with 18-inch wheels, high-performance tires, sport-tuned steering and suspension, a manual transmission, a limited-slip differential, upgraded brakes, unique styling elements and front sport seats. The G37 Journey can be equipped with a Sport package, which adds all the above performance bits without the manual transmission, but with magnesium shift paddles on the steering wheel. The G37x also offers an optional Sport package, though it is essentially an appearance package with 18-inch wheels carrying all-season tires, unique exterior styling and sport seats.
The Technology package (not available on the Sport) adds adaptive cruise control with collision-mitigation braking, automatic wipers and an upgraded climate control system with an air purifier.
Powertrains and Performance
The 2013 Infiniti G37 packs a 3.7-liter V6 good for 328 horsepower and 269 pound-feet of torque. A seven-speed automatic is standard on the rear-wheel-drive Journey and all-wheel-drive G37x. A six-speed manual is standard on the G37 Sport. In Edmunds performance testing, a G37 Journey (with the optional Sport package) went from zero to 60 mph in a rapid 5.4 seconds. EPA-estimated fuel economy is 19 mpg city/27 mpg highway and 22 combined for the Journey, 18/25/20 for the G37x and 17/25/20 for the Sport.
Every Infiniti G sedan comes standard with antilock brakes, stability and traction control, front side airbags and side curtain airbags. A rearview camera is standard on all G37 trims and, when equipped with the Technology package, the adaptive cruise control sensors will automatically trigger the seatbelts to pre-tension if an accident is deemed imminent.
In Edmunds brake testing, a Sport-package-equipped G37 Journey came to a stop from 60 mph in an outstanding 106 feet.
In crash testing by the Insurance Institute for Highway Safety, the G sedan received the top score of "Good" in the frontal-offset and side-impact tests, but the second-best rating of "Acceptable" in the roof-strength test. The G37 also earned an "Acceptable" rating for the institute's new "small overlap" frontal-impact test. Only a few cars have been subjected to this test thus far, and many fared worse than the G.
Interior Design and Special Features
The G37 offers user-friendly controls and excellent build quality. The handsomely designed interior is highlighted by the car's standard leather seating and leather-accented magnesium shift paddles as well as the Japanese "Shodo" aluminum trim (or optional maple wood trim). Overall, materials quality isn't quite up to Audi or Mercedes standards, but considering its price the Infiniti sedan does give a BMW 3 Series pause.
The front seats are comfortable and supportive, while the available sport-styled seats offer even more aggressive side bolstering, though they may be a bit too snug for larger drivers. The backseat offers respectable space for this class, with the exception of the narrow center seat.
The G sedan benefits from Infiniti's user-friendly electronics. The standard color display and iPod interface are among the best available, while the myriad audio, climate and navigation controls are easy to decipher. The available Bose stereo is particularly impressive as well. Trunk space, at 13.5 cubic feet, is about average for this class of car.
The 3.7-liter V6 found in the 2013 Infiniti G sedan is quite strong and provides quick acceleration. While we're not fans of the coarse noise the engine makes in the G37 at higher engine speeds, for the money, you can't beat it in this class. Handling is also praiseworthy, as the G attacks curves with aggression and precision, yet remains poised and compliant when driven over less than perfect pavement. Steering feel is commendable and responsive, particularly with the Sport package's quicker steering ratio. This setup provides excellent feedback and a pleasant weightiness that builds progressively when cornering.
The seven-speed automatic transmission is mostly faultless and when shifted manually provides quick gearchanges via the column-mounted paddle shifters. To the delight of enthusiasts, downshifts are swiftly executed with precise throttle blips to match revs. In testing, however, we've noticed that upshifts, even when in Drive, aren't as smooth as they should be for this class of car. For those who prefer three pedals, this is one of the few cars this size that can be had with a manual transmission, and this six-speed's shift linkage has a pleasing bolt-action feel through the gates.

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.

I got this G37 RWD Journey to inject some fun in my family car/ 100 miles/day commute routine. It delivered mostly with its responsive engine, communicative steering and pretty stiff but competent suspension. I have a slight issue with the automanual though - it is supposed to have the rev-matching feature but so far it seems to over-rev quite a bit -
so the car surges forward on downshifts (3->2 especially). The seats are nicely shaped but somewhat hard on the bottom - the heater element might be the cause. Anything in the front cupholders seems to get in the way of operating the gearshift stick. The maintenance alert system relies on simple mileage and does not monitor oil/engine state.

This is the second G Sedan X that I have owned.
My first was an 07 G35X and I loved it!
I just traded it in and got an 13 G35X.
You won't regret the decision of buying this car.
Great price backed up by reliability and great customer service.
I didn't have one problem with my first G and it had 68,000 miles on it when I traded her in.
My only issue would be that the interior and exterior styling hasn't changed very much even in 6 years! But, I guess you don't wanna mess with success.
And as far as performance goes, you will not be disappointed. With an avg of 20mpg and 0-60 in the low 5.0 range you can't lose. And lastly, the Bose system and interface is amazing.

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.
