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 got this car for my 17th birthday with 30,000 miles on it. So far, I have loved it and there are only a couple things to complain about. First, let me start off by saying the sound system is phenomenal. The BOSE system sounds amazing. However, if you are easily annoyed by rattles, this car might not be for you. There are several rattles that I can't seem to fix. My other major complaint is about the quality of the paint. After 60,000 miles, the paint is completely chipping off of both bumpers. Other than that, this is an awesome car!"

"This is my 5th Infiniti in the last 30 years. Infinitis are very reliable. My last car was an I 30 and had all the bells and whistles. I never changed a headlamp or light bulb in the 10 years of ownership. I was never stranded..just regular maintenance and zoom zoom. I decided to buy the new G37 just because I wanted something new. I test drove several editions of the G-37.. I decided on the G37S for its classy sporty look. After 6 months I wished I had not selected the Sports edition just because of the ride..I was so used to that luxury feel. This car is great but with low profile tires and suspension, I wished I had chosen the basic model. Another thing...the brakes squeal in the morning... after a few pumps they are fine, but it can be somewhat embarrassing when you buy a 40K car and the brakes squeal. I hope there is a fix down the road. I am told it is known issue, although I have never had that problem with previous Infiniti cars."
