The 2009 Infiniti G37 is a true sport sedan; it may be a little harsh for poseurs, but true driving enthusiasts will love it.
Infiniti completely redesigned its G35 sport sedan for 2007; now for 2009 the G gets an even more powerful 3.7-liter engine and seven-speed automatic and is appropriately renamed the G37 Sedan.
Appearance-wise, the G Sedan has changed very little for 2009, and that's a good thing. The 2009 Infiniti G37 Sedan has a rakish silhouette that shouts rear-wheel-drive sport sedan, and its styling involves clean expanses of sheetmetal—a nice departure from the excessive body creases in many models' flanks nowadays. It contrasts nicely with crisp contour lines around the headlights and grille, and a trunklid spoiler is subtle. The overall effect is at once tasteful and conservative, yet also aggressive and sporty.
Inside, the G37 has the cockpit feel of a sports coupe in front, with narrow footwells, a rather low seating position, and a prominent center console that wraps back between occupants. Big round dials are set directly in front of the driver, and a strong beltline wraps around to the door panels. A screen mounted top and center accesses audio and climate functions, while supplemental controls are just under the screen.
The new 3.7-liter V-6, which debuted on the G37 Coupe last year, makes 328 horsepower and 269 pound-feet and is mated to an all-new seven-speed automatic transmission or a six-speed manual. All-wheel drive is available, but only with the automatic. Underneath there's a firm, sport-tuned four-wheel independent suspension, and power steering adjusts effort according to vehicle speed.
Despite the bump in power, the new Infiniti G37 Sedan gets better fuel economy than the old G35; with the automatic transmission it now rates at 18 mpg city, 26 highway. TheCarConnection.com failed to meet these estimates, seeing mid-teens around town and 24 mpg over an exceptionally gentle highway run.
The G37 Sedan is one of the most responsive, communicative, and fun-to-drive sport sedans in its class. The larger V-6 feels stronger throughout the rev range and has enough thrust to satisfy most rabid performance enthusiasts, though it's more obtrusive than former 3.5-liter versions of this engine and not as smooth through the rev range as BMW's excellent turbocharged six in the 335i. Its character is a bit raspy, turning raucous when revved upward to its 7,600-rpm redline.
The new seven-speed automatic transmission in the 2009 Infiniti G37 Sedan pulls off snappy and smooth shifts when accelerating hard, but shifts become lumpy when light on the throttle, and it seems indecisive right after making sharp right-hand corners at intersections. The transmission feels more in its element when driving aggressively on a tight, curvy road, as the solid-magnesium steering-wheel paddle shifters (included on G37 Journey and G37x AWD models) command a quick downshift that includes a throttle blip. Those who like a manual transmission will find the six-speed very satisfying.
For those who value steering and handling above all else, the G37 Sedan is TheCarConnection.com's pick of the sport-sedan stable—even, quite possibly, better than the BMW 3-Series. But also be aware that the G37 isn't the right choice for those who expect a lot of refinement and silence in their luxury sport sedan. The G37's ride isn't downright jarring, but it's quite firm, and road noise is more prominent inside than it is in most other sport sedans. That said, the G37 Sedan can bring all the capability and thrills of most top-echelon sport coupes.
Optional on the rear-wheel-drive Sport models is the new Four-Wheel Active Steer system, which helps make quick changes of direction a little crisper and more stable. 2009 Infiniti G37 Sedan Sport models also include a Viscous Limited Slip Differential, in addition to a host of track-worthy upgrades like larger vented disc brakes, sport steering gear, W-rated performance tires, and more aggressively bolstered sport seats with active head restraints and thigh extensions.
The G37 Sedan offers decent space in front; even the standard seats have good support, though others might find it a bit narrow and snug. Headroom is somewhat scarce but good enough for most. The backseat is hardly a place for adults to spend long periods of time. Headroom is OK, but the lower cushions are short, legroom is tight for the tallish, and seatbacks feel more reclined than they should be. Trunk space is a pleasant surprise, but instead of folding forward, the backseats only include a pass-through good for skis and such. The overall look and feel of the G37's cabin is impressive; it's put together tightly and the materials have more in common with those in Infiniti's upscale M. The standard metallic finish has a nice look, but the available African rosewood makes it feel like a warmer luxury sedan.
The 2009 Infiniti G37 is offered in four different models for 2009: Base, Journey, Sport, and the G37x AWD. The Base, Journey, and AWD models are very well equipped, with only slight differences in equipment; Journey models include dual-zone climate control and a six-disc changer, while AWD models get heated seats and mirrors in addition to the Journey upgrades. The Journey isn't that much pricier, but you'll need to step up to it to add any of the G37's impressive options, including a navigation system with XM NavTraffic and a 9.3-gigabyte Music Hard Drive, Adaptive Front Lighting, and Intelligent Cruise Control with a Preview Braking safety feature.
Crash-test ratings for the G37 Sedan have been respectable, with four- and five-star results from the federal government and top "good" scores from the IIHS for frontal and side impact. The only concern is a "marginal" rating from the IIHS in its seat-based rear-impact test. Electronic stability control is standard on the G37, as are anti-lock brakes with Brake Assist, front side airbags, and side-curtain airbags that cover front and rear outboard occupants.
2009 INFINITI G
If flowing, sensuous sport sedans are your thing, then you won't want to miss the 2009 Infiniti G37 sedan.
The latest addition to Infiniti's best-selling model, the G-series sedan and coupe, is the 2009 Infiniti G37 sedan, which is nearly unchanged in the styling department compared to the outgoing G35.
TheCarConnection.com's research shows the automotive press is very pleased to find that Infiniti, by and large, leaves the Infiniti G37 sedan's styling untouched. Prospective buyers have the choice of four trim levels for the Infiniti G37, which Cars.com lists as "base, Journey, Sport 6MT and G37x," with the x variant featuring all-wheel drive. For Infiniti's 2009 G37 lineup, Kelley Blue Book finds that the "well-tailored sheetmetal effectively complements the G37 sedan's sporting character" as it tastefully blends "crisp lines and sensual contours" to make a "visually distinctive styling statement." Indeed, the 2009 Infiniti G37 is one of the most instantly recognizable cars on the road; Edmunds reviewers note as much when they contend that the Infiniti 2009 G37 "looks distinctive...from its swoopy exterior styling to its origami paper-inspired 'Washi' aluminum interior trim." Car and Driver also raves about the "crisp styling" on the exterior of the Infiniti G37, which Kelley Blue Book says is highlighted by "an eye-catching grille treatment with four sculpted bars that twist from center to edge like traditional Japanese sword blades."
Infiniti's strong corporate styling language continues inside the cabin of the Infiniti 2009 G37 sedan, where Kelley Blue Book finds "aluminum accent trim textured to resemble traditional Japanese handmade paper." Car and Driver reports that, like the exterior, the interior design is unchanged, with "the only immediately noticeable change [being] the switching of the seat-heater controls from toggle switches to rotary knobs." Otherwise, Car and Driver says, the cool styling elements "and phenomenal steering wheel remain." Other major positives for the interior include the fact that, according to ConsumerGuide, "the navigation system itself is refreshingly easy to use, and many audio and climate functions are separate from it." Overall, Kelley Blue Book feels that the 2009 Infiniti G37's "cockpit-like ambiance may strike some as a bit busy," but at least "the controls are logically arrayed and the flashy electroluminescent main gauges are quite legible."
2009 INFINITI G
The BMW 3-Series is a lofty benchmark, but the 2009 Infiniti G37 comes as close as anything on the road to matching "The Ultimate Driving Machine" when driven hard.
Sport sedans are, first and foremost, judged by their performance credentials, and on paper the 2009 Infiniti G37 sedan is well equipped to hang with its main target, the BMW 3-Series. Reviews read by TheCarConnection.com show that Infiniti's 2009 incarnation of the G37 sedan is no mere paper tiger either, and 3-Series numbers are easily within reach of this four-door rocket.
Under the hood of each and every 2009 Infiniti G37 sedan is a "3.7-liter V-6" that Road and Track calls "the latest iteration of the highly regarded VQ family," capable of delivering "328 hp at 7000 rpm and 269 lb.-ft. of torque." Those familiar with the Infiniti lineup will recognize the engine as the same one that propels the Infiniti G37 coupe, albeit with 2 fewer horsepower. Reviewers are unanimously impressed by what Edmunds labels the Infiniti G37's "fierce acceleration," while ConsumerGuide reports that the engine "satisfies at any speed" and makes "passing maneuvers...a breeze." Motor Trend reviewers clock the fastest acceleration times of any review magazine, stating that "zero to 60 now takes only 5.0 sec, with the quarter-mile obliterated in just 13.5 sec at 105.3 mph."
In addition to the new higher-output engine, the Infiniti G37 gets a transmission upgrade for 2009. Road and Track says that the Infiniti 2009 G37 lineup picks up a "new 7-speed automatic transmission on base, Journey, and awd models," while "a 6-speed manual gearbox is standard on the G37S." The automatic is also "available with steering-column-mounted shift paddles," according to Automobile Magazine. Reviews of both transmissions are mixed, but the automatic seems to draw more than its fair share of criticism. Edmunds cautions that "upshifts are never luxury-sedan smooth, even in Drive," and once you "switch to Driver Sport or manual, forget about it—you've got yourself a veritable Lurch-o-Matic." Car and Driver agrees, noting that "upshifts in manual mode could be smoother and more quickly effected." On the positive side, ConsumerGuide calls the auto "alert and responsive," and while it "seems busy in some situations," they find it "generally smooth and prompt" overall. Car and Driver reviewers characterize the Infiniti 2009 G37's manual transmission option as "better behaved" than on previous versions, with "throws [that] remain short but high-effort, the latter a trait shared with the clutch."
Many drivers who plan on commuting daily in the Infiniti G37 sedan will gladly live with the sometimes harsh automatic transmission simply because it manages to boost overall fuel economy for the sedan. According to the official EPA estimates, the Infiniti 2009 G37 sedan with the seven-speed automatic should return 18 mpg city and 26 mpg highway, compared to the manual's 17 mpg city and 25 mpg highway. The all-wheel-drive version suffers from the expected fuel economy penalty and serves up 18 mpg city and 25 mpg highway.
Reviewers are very enthusiastic about the 2009 Infiniti G37 sedan's handling capabilities, which are among the best in the sport-sedan class. In particular, ConsumerGuide reports that "steering feel is precise and direct," while the "available Four-Wheel Active-Steer System provides particularly sharp moves." Edmunds agrees, proclaiming "one aspect of the 2009 Infiniti G37 that deserves unequivocal praise is its handling," especially the steering wheel, which is "alive with information." Motor Trend lists some of the 2009 Infiniti G37's traits as "well-balanced, easy to induce oversteer, taut ride," and calls it "a step quicker" than its predecessor. ConsumerGuide also finds that "braking is strong and secure" on the Infiniti G37. Kelley Blue Book calls the 2009 Infiniti G37 a marvel of suspension engineering, noting that the "finely-tuned suspension delivers [an] impressively balanced ride and handling," making for a car that, when "driven normally...coddles, comforts, and entertains."

Comfort & Quality
Comfortable seats are to be expected on the 2009 Infiniti G37, but at this price range, road noise should be more hushed at highway speeds.
The 2009 Infiniti G37 sedan isn't without its flaws, and most of them are evident within the cabin, where the G37 proves it isn't the most refined or spacious entry in the sport sedan segment.
One of the Infiniti G37's biggest interior attributes is its pair of front bucket seats, which Kelley Blue Book calls "amazingly comfortable and supportive," with standard "eight-way power adjustment for the driver and four-way for the passenger, plus manually adjustable lumbar supports." Other reviews read by TheCarConnection.com enthusiastically agree, with ConsumerGuide adding that "the seats in Sport models have additional side bolstering to keep occupants planted in fast cornering." Unfortunately, while Cars.com says the 2009 Infiniti "G37 seats five," Kelley Blue Book reviewers warn that "rear passengers will find the G37 sedan's rear bench seat belted for three but contoured for two average-sized adults at best." On the positive side, Edmunds points out that rear "passengers are treated to a satisfactory amount of headroom and legroom for a sport sedan, though the cushion is rather low."
If you plan on using the 2009 Infiniti G37 for weekend thrills, then you probably won't care too much about its available cargo space. For those with more utilitarian plans regarding the Infiniti G37, ConsumerGuide's criticism of "interior small-item storage space [as] just fair" will come as a bigger disappointment. The trunk isn't particularly large either, measuring just 13.5 cubic feet, but Edmunds reviewers claim it proves "surprisingly capacious," thanks to its intelligent layout.
Don't expect to be blown away by the materials inside Infiniti's 2009 G37 lineup, especially considering the price you'll pay for the privilege of owning one. ConsumerGuide claims that "assembly quality and most interior materials are on target for the class, with real aluminum or wood trim available." Edmunds agrees, pointing out that "materials are mostly of high quality, though the pebbled plastic on the center console feels downmarket, as does the flimsy overhead map-light housing." On the positive side, Edmunds deems "fit and finish [is] generally good," while Cars.com notes the numerous "high-quality materials" inside the Infiniti 2009 G37's cabin.
One area where current G35 owners will wish for improvement—and find none—is in the Infiniti 2009 G37's cabin noise levels. Motor Trend reviewers "noticed more noise than [they were] expecting" during their test drives, while Edmunds reports that they "found road noise to be an issue during highway cruising." ConsumerGuide agrees, observing that "road noise is evident on coarse surfaces, especially with the tires included on the G37 Sport."

The 2009 Infiniti G37 sedan puts safety first thanks to its wide range of standard features and a robust structure.
Crash-test ratings are the first stop for anyone researching vehicle safety, and the 2009 Infiniti G37 doesn't disappoint in this category. Moving on to safety features, TheCarConnection.com's research shows that Infiniti's 2009 sport sedan offers all the expected safety sentinels to watch over the car.
The Infiniti G37 sedan lineup has been subjected to both NHTSA's and the IIHS's battery of crash tests and emerged with a very strong report card. In NHTSA tests, the 2009 Infiniti G37 earned a perfect five-star rating in both side-impact categories, as well as five stars in the front driver impact category. The only blemish in NHTSA tests came in the front passenger impact test, where the Infiniti G37 scored four out of five stars. The Infiniti 2009 G37 lineup's IIHS tests were equally impressive, with the sedan earning the highest possible rating, "good," in both the frontal offset impact and side impact tests.
Regarding safety features, the 2009 Infiniti G37 sedan comes loaded. Kelley Blue Book states that "standard safety features on all include front, front-side and side-curtain airbags, active front-seat head restraints," and a variety of electronic systems. Cars.com adds that one of the Infiniti G37's unique features is "a preview braking function that preloads the brakes for faster response if a car in front of you slams on its brakes"; other features include a "standard first-aid kit" and "optional rearview camera (not on base model)." Anti-lock brakes are also standard on all of Infiniti's 2009 G37 models.
One important safety feature you might not find listed in a sales brochure is the excellent visibility afforded by the Infiniti G37's design. Edmunds says the "driving position is excellent, with a relatively low cowl that affords a commanding view of the road." Parking lot maneuvers are aided by the available rearview camera, which helps drivers spot small obstructions behind the Infiniti G37.
2009 INFINITI G
High-tech features are more accessible in the 2009 Infiniti G37 than in any other car in its class.
The 2009 Infiniti G37 draws praise for its extensive standard features list, but reviews read by TheCarConnection.com show that if the basics aren't enough for you, a variety of options are available both as stand-alone features and grouped together in packages.
For Infiniti, 2009's lineup of G37 sedan models is largely similar in terms of standard equipment. Kelley Blue Book reports that all Infiniti G37's are "exceptionally well appointed, [and] even the base G37 Sedan offers leather upholstery, a full range of power assists...[and] steering wheel-mounted supplemental audio and cruise controls." TheCarConnection.com's editors also note that a six-disc, six-speaker AM/FM/MP3 sound system is included as standard fare on the Infiniti 2009 G37 lineup. Kelley Blue Book remarks that "automatic air conditioning and high-intensity discharge (HID) bi-xenon headlights" round out the Infiniti G37's features list.
Moving on to the options list, Road and Track reviewers note that Infiniti's 2009 G37 lineup "can be enhanced with four-wheel steering, rosewood trim, navigation with rearview monitor, pre-crash seatbelts and adaptive headlights." Edmunds adds that the 2009 Infiniti G37 can be outfitted with an optional Bose sound system that they say "is one of [their] favorites, delivering stellar sound reproduction without the intrusion of complicated graphic equalizers or other high-tech sound-tailoring gewgaws." Edmunds also raves about the optional navigation system, which is "one of the best [they've] encountered, with intuitive controls and a clear and attractive display." Kelley Blue Book lists some of the other optional features as the Premium Package, which tacks on a "moonroof, Bose audio system, power tilt and telescoping steering column, Bluetooth and more," while the Technology Package brings "Intelligent Cruise Control [and] adaptive front lighting" to the mix. The Navigation Package for the 2009 Infiniti G37 sedan includes Infiniti's Lane Guidance system and a 9.3GB hard drive for onboard music storage.
