Infiniti's G Sedan was the first Japanese luxury car that could truly compete with the best European compact and mid-size luxury performance sedans. This statement still holds true today, which is why the 2011 Infiniti G37 sedan remains one of our favorite four-door rides. The G37's combination of performance (it's powered by the same engine found in the Nissan 370Z sport coupe), luxury and price give it a leg up on models such as the Audi A4 and BMW 3-Series, as well as domestics such as the Cadillac CTS and Lincoln MKZ. Toss in the G37's impressive safety, reliability and resale value, and it's hard to make an argument against Infiniti's sales leader.
Those who don't think you should have to sacrifice a comfortable ride or creature comforts in order to enjoy exhilarating performance and handling will be quite happy behind the wheel of a G Sedan.
Whether real or imagined, loyal European sedan zealots will somehow find issues with the way the G37 and G25 perform. Those willing to give up rear-seat legroom and a lot more of their hard-earned cash may find more to like in an Audi RS4 or BMW M3.
For 2011, Infiniti adds a new, lower-priced G25 to the lineup. The G25 is powered by a 2.5-liter V6 engine developing 218 horsepower and features a seven-speed automatic transmission. Offered in three trims, the addition of the G25 model to the exiting G37 lineup makes for a total of eight trims from which to choose.
Driving Impressions Derived from a long-wheelbase version of Nissan's latest FM (Front Mid-ship) platform, the G37 possesses dynamic performance credentials that only improve when coupled with the G37 Sport Package. Under normal...driving conditions, the G37 sedan pampers its occupants with a host of electronic goodies and a smooth ride that is never harsh or jarring. Drive it enthusiastically, and the G37 satisfies like few competitors can. Its tenacious 3.7-liter V6 pulls strongly on demand, whether backed by the seven-speed automatic or six-speed manual transmission. All variants benefit from a driver-selectable Vehicle Dynamic Control (VDC) system that lets you explore an ample portion of the car's ultimate potential before the system swings into action. Those willing to forego a bit of at-the-limit edge for the all-season security of all-wheel drive should consider a G37x. On a G37 fitted with the Sport Package, the automatic also features steering column-mounted shift paddles that are ideally positioned for quick gear changes.
Power front seats
Amazingly comfortable and supportive, even the base G37's front seats boast eight-way power adjustment for the driver and passenger, plus manually-adjustable lumbar supports. The Sport 6MT seats include power activation for the thigh, lumbar and side bolsters.
Hard Drive Navigation
This all-in-one information center not only offers voice-activated navigation, it includes satellite radio-linked traffic and weather updates, Zagat restaurant guide, streaming Bluetooth for audio, 9.3-gigabyte music box storage and DVD playback capability.
The 2011 G37's interior is wrapped in soft leather and warm wood, pampering every sense in a cocoon of luxury and elegance. Supremely comfortable form-fitting leather-clad front seats are a welcome addition, as is the available aluminum trim textured to resemble handmade Japanese paper. While some might find the G37's cockpit somewhat busy, the soothing white on black gauges and large, easily identifiable controls are logically arranged and are within clear view. The one area of exception might be the center stack that, with or without navigation, is sometimes susceptible to varying degrees of sunlight.Exterior
The 2011 Infiniti G37 and G25 Sedans are wrapped in a well-tailored suit of sleek sheetmetal, adorned with just the right amount of chrome trim and subtle body extensions as to avoid looking over-styled. Infiniti's distinctive grille is comprised of four sculpted bars that twist from center to edge mimicking an ancient Japanese sword blade. The front end treatment is finished off with a set of large L-shaped headlamps and lower fog lights, while the rear displays oversized tail lights that follow the flowing contours of the car's rear fenders. G25 and G37 trims ride on stylish 17-inch alloy wheels, while the top-line G37S Sport 6MT and G37x models have W-rated 225/50 front and 245/45 rear tires on 18-inch alloy rims.
Exceptionally well-appointed, even the base 2011 G Sedan offers leather upholstery, a full range of power assists – including an eight-way power driver's and four-way power passenger seat - steering-wheel-mounted supplemental audio and cruise controls, Intelligent Key remote entry and push-button start, six-speaker AM/FM/MP3-capable audio with auxiliary input, automatic air conditioning and high-intensity-discharge (HID) bi-xenon headlights. The Journey, x and G37S Sport 6MT bring Infiniti's RearView Monitor, eight-way power passenger seat, Bluetooth hand-free phone connectivity, heated outside mirrors, a USB connection port and other detail upgrades. Standard safety features on all include front, front-side and side-curtain airbags, active front-seat head restraints, Vehicle Dynamic Control (VDC) with stability and traction control and anti-lock brakes (ABS) with Brake Assist (BA) and Electronic Brake force Distribution (EBD).
The 2011 Infiniti G25 has only a few options such as a power sunroof and rear decklid spoiler. The G37 offers multiple upgrade packages and several individual extras, although only for the Journey, G37x or G37 Sport 6MT models. Key groups include the Premium Package (moonroof, Bose audio system, power tilt and telescoping steering column and more); Sport Package (sport seats, four-piston sport brakes, unique front fascia and side sills, 18-inch wheels and tires, limited-slip differential and magnesium paddle shifters with the automatic); Technology Package (Intelligent Cruise Control, rain-sensing wipers and more); and the Navigation Package (voice-activation, real-time XM NavTraffic, Lane Guidance and a 9.3GB Music Box hard drive). Also available are Maple accent interior trim and a rear spoiler.
The G25 is fitted with a 2.5-liter V6 engine and seven-speed automatic transmission. The G37's stellar V6 is the latest iteration of Nissan's renowned VQ35-series engine. This all-aluminum 3.7-liter is loaded with design elements that help reduce internal friction and increase total performance, including continuously variable timing on both the intake and exhaust valves. It delivers a stout 328 horsepower and 269 pound-feet of torque, is matched with either a seven-speed automatic (G37, G37 Journey or G37x) or close-ratio six-speed manual transmission (G37S Sport 6MT) and returns slightly above-average fuel economy numbers.

I own this car - My approximate mileage is 43,000overall rating 7 of 10rating details
Pros: "Nice looking, powerful, well appointed car"
Cons: "Rough transmission, hollow sound to the back doors"
Likely to recommend this car? (1-10): 5
"The car is appointed nicely, it has more than sufficient power, comfortable seating, a/c and stereo controls within easy reach. The satellite radio reception is poor at times for no apparent reason. I do not like the transmission and how it shifts especially at low speeds as when in traffic, slowing down and then accelerating. I have driven newer models of this car and the transmissions were quite different (smoother) so Infiniti must have realized the roughness. My dislike of the transmission may be the rear wheel drive aspect of the car but it will be the reason I trade in this car."

I own this car - My approximate mileage is 55,000overall rating 5 of 10rating details
Pros: "Fun to drive, great interior"
Cons: "Poor convertible roof mechanics, lacks sensors"
Likely to recommend this car? (1-10): 2
"Straight to the point: Great driving experience, interior features, sound system. But, Issue with this car: the convertible feature is very delicate. My experience dictates that once the roof starts giving any kind of trouble (and chances are it will, multiple customers reporting issues), there is very little a user or the company can do. I am struggling with multiple roof issues for past 2 years, including rattling noise (now it makes noise even driving on interstates with perfect roads), irritating alarms, false coding on the sensors, timing disturbances of the motor mechanics etc. Its literally one after another. My car is at the dealership for these issues 1-2 times a month, no one seems to understand the problem, and blame game continues. . Contacted DOM service, and Infiniti consumer affairs, no real success. Seems like its a new technology for Infiniti and needs significant improvements. This car has lots of great features, but this mind boggling issue pretty much downplays anything fun this car can boast of. Improvement in this aspect is the key for future success of this car. Everything else is manageable, but just for the sake of mentioning: You will also notice that a car of this value lacks few features like remote start, side blinkers etc. Also the trunk space is the center of all jokes in the car world once the top is down. And it lacks a very crucial feature: the trunk doesn't have any sensor to inform the user if there is something in the trunk and that one should not attempt to operate the roof in this situation."

"I bought my G35X with 26k miles certified to 100k miles. It has had ZERO issues, so reliable and easy, just get in and drive! Handles great in the snow. It's a sporty drive, this is not your grandpa's car so if you want that kind of experience, the G35x would not be for you. Have really loved this car."
