The Infiniti G37 Coupe isn’t just incredibly fast and nimble; it's good-looking in a well-heeled way.

TheCarConnection.com's editors drove the new Infiniti G37 Coupe in order to give you an expert opinion. TheCarConnection.com also researched available road tests on the new Infiniti G37 Coupe to produce this conclusive review and to help you find the truth where other reviews might differ.

Introduced last year and available in three different models (base, Journey, and Sport), the Infiniti G37 Coupe is joined by a fourth model for 2009, the G37x Coupe AWD. The new coupe utilizes Infiniti’s ATESSA E-TS all-wheel-drive system found on other Infiniti models.

The 2009 coupe's engine received a boost to 330 horsepower last year; redline is a high-revving 7,500 rpm. A new seven-speed automatic transmission with Drive Sport (DS) Mode and Downshift Rev Matching enhances the driving experience, working with electronic controls that help the box shift smarter, especially on the track where the downshift rev-matching keep the chassis balanced and the engine in the power band.

Compared to the Nissan 350Z, with which the G37 shares some unseen mechanicals, the G37 is far more suave outside and inside, with two additional seats in back. But honestly, while the G37’s front seats are very comfortable, the rear ones are nearly useless.

The 2009 Infiniti G37 comes with a stiff chassis, double-wishbone front suspension, a multilink arrangement out back, and stabilizer bars at both ends. At the corners are massive disc brakes. Base models get 13-inch platters all around, while 14-inch (front) and 13.8-inch units are used on the Sport 6MT variant. Covering the discs are aluminum 18-inch rims on the base, and 19-inch rims for the Sport 6MT.

Directing all this high technology is rack-and-pinion steering gear with electric, as opposed to hydraulic, assist. The feel of the steering isn’t ideal, however. On the track, it sometimes varies the effort unexpectedly, which is disconcerting. Roadholding is fantastic, while the ride is a bit nervous, thanks to big tires and a short wheelbase.

The 2009 G37 Coupe is as well-equipped as luxury coupes typically come, and the standard feature list includes automatic climate control, an intelligent key, and leather upholstery. Journey models get upgraded audio and a dual-zone climate system, and enable tech options like intelligent cruise control, adaptive front lighting, a hard-drive based nav system, and four-wheel active steering. A self-healing clearcoat finish called Scratch Shield paint helps make the G37 more appealing. 2009 models also feature a redesigned dial-type seat heater switch and automatic speed-sensing power door locks.

The current Infiniti G37 has sexy, seductive exterior styling and fresh interior styling.

Updated but still gorgeous styling is the norm on the 2009 Infiniti G37. The interior of the 2009 Infiniti G37 especially wins favor with reviewers.

Edmunds loves the "user-friendly controls" and "handsome design," while Car and Driver deems the interior, which features "a color monitor to control the radio, climate-control, and optional nav system," to be "pleasant enough." Cars.com also feels that the interior of the Infiniti G37 "is a vast improvement over the first-generation G35, and now features such novelties as aluminum trim modeled after Japanese Washi paper." Rounding out the praise of the interior, Kelley Blue Book reviewers find that "the seven-inch LCD screen included on all models" of this Infiniti 2009 coupe "radiates colorful and attractive graphics that further enhance the new model's more contemporary vibe."

There are three trim levels available for the 2009 G37; however, telling them apart from the outside can prove difficult. Edmunds reports that the three trim levels of this Infiniti 2009 include "base, Journey and Sport 6MT," and the only real difference between them is that the base and Journey come "standard with 18-inch wheels," while the Infiniti 2009 G37 in Sport 6MT trim features "19-inch wheels." Aside from the different wheels, all versions of the 2009 Infiniti G37 look "great (albeit in a more voluptuous sort of way than the original)," according to Edmunds.

Reviews read by TheCarConnection.com rave about the exterior of the Infiniti G37, with ForbesAutos praising the "fresh, elegant styling" of this Infiniti 2009 coupe. Automobile adds that the front "looks muscular and tough in person," and "overall, it's a subtle evolution of a great design." Cars.com describes the "curvaceous body" as integrating "large—but fairly subtle—fenders, while the bumper boasts one of the more sinister interpretations of the familiar air dam and side portals you see on many cars."

2009 INFINITI G37 Coupe


The 2009 Infiniti G37 meets all the criteria of a true performance car.

The 2009 Infiniti G37 moves quickly and confidently. From its sweet V-6 engine to its responsive handling, the Infiniti G37 is ready to be pushed to the limit, and it proves its worth as a comfortable commuter as well.

Reviews read by TheCarConnection.com are suitably impressed with the G37’s one engine option, which Car and Driver says is "a 3.7-liter version of Nissan's venerable VQ V-6 engine," and on the Infiniti G37, the "power is at 330, and the torque output at 270 pound-feet." ForbesAutos reports "acceleration was strong and smooth" during their test, and "the engine makes great music as it happily revs to the red line." Edmunds reviewers push the Infiniti 2009 G37 to the limit and find that a "G37 Journey accelerated to 60 mph in 5.5 seconds, while a Sport 6MT coupe pulled a nearly identical 5.4 seconds to 60 mph." When compared to the old G35 sedan and its 3.5-liter engine, the Infiniti 2009 G37's extra power is "certainly felt, especially when accelerating out of turns," declares Motor Trend.

The 2009 Infiniti 2009 G37 is available with one of two transmissions. Edmunds notes that "the base and Journey trim levels come standard with a seven-speed automatic transmission with paddle-shift automanual control, while the Sport 6MT features a six-speed manual." Reviewers are impressed with both transmissions, and ForbesAutos proclaims "both gearboxes work precisely and are well matched to the potent engine." Automobile Magazine is comfortable enough to take sides, though, and they state that their "choice is distinctly for the 6MT," where the "tail-out antics and fun factor outweigh the coarseness" that they feel comes with the manual transmission.

The EPA estimates for a 2009 Infiniti G37 with the manual transmission are 17 mpg in the city and 26 on the highway, while the automatic transmission boosts city numbers to 18 mpg but drops to 24 on the highway. Cars.com finds that "Infiniti estimates that the G37's engine actually delivers around 1 mpg better gas mileage than the 3.5-liter V-6 in the G35."

The performance strong points of the 2009 Infiniti G37 are its handling and overall driving experience, not just the car’s inline acceleration. Kelley Blue Book affirms that "performance-focused drivers hoping for a more sophisticated, premium-badged Nissan Z will find satisfaction in" the Infiniti G37. Other reviewers agree, and Motor Trend says "through all but the most aggressive curves, the car stays as flat as the Arizona desert." Car and Driver points out that, even with the sport package, "the chassis soaks up road bumps without the slightest chatter, and the steering remains precise and communicative." While a "four-wheel active steering (4WAS)" system is available, according to Edmunds, they recommend sticking "with the standard steering setup," as the 4WAS system "fails to weight up properly in the corners and provides limited feedback." When it comes time to stop the Infiniti 2009 G37, Motor Trend finds that the brakes are "stellar—exhibiting excellent response and pedal feel and no fade."

Comfort & Quality

The 2009 Infiniti G37 isn’t the roomiest, but it’s extraordinarily well built.

The 2009 Infiniti G37 boasts an upgraded interior but suffers from a lack of storage space.

Reviewers simply can't say enough about what Edmunds calls the "excellent build quality." Kelley Blue Book also attests that their "'most improved' vote goes to the passenger cabin," where features like "the visually soft aluminum alloy trim (inspired by Japanese washi paper, Infiniti says), as well as the optional African rosewood trim," help bring an upscale ambiance. Motor Trend reviewers conclude that the various interior upgrades "collectively raise the bars of luxury and sport," and they praise the "finer fit and finish" on this Infiniti 2009 coupe.

As much as reviewers enjoy the build quality of Infiniti G37, they unanimously focus on the car’s lack of storage space. Edmunds reviewers are quick to state "the trunk is on the small side, with only 7.4 cubic feet of space." Car and Driver also finds that, compared to the similar G35 sedan, there is a "loss of rear-seat and cargo space" on the Infiniti 2009 G37 coupe, hindering its usability as a daily driver. One nice feature that helps improve cargo space is the fact that "the rear seatbacks fold down to expand the trunk," according to Cars.com.

Other reviews read by TheCarConnection.com illustrate that four adults do not fit comfortably inside the 2009 G37. Car and Driver says, "adults sardined in the back are faced with the option of tilting their heads sideways or slouching past the point of reasonable comfort." Edmunds adds that "as in many coupes, rear legroom is scant, and rear headroom is particularly compromised by the G37's severely raked back window." On the positive side, Kelley Blue Book notes that "except for limited headroom, the rear seats" on the 2009 Infiniti G37 "are more accommodating than might be apparent."

Regarding the forward part of the cabin, Car and Driver points out that "as in any coupe, the front seats are the place to be," and the front seats on the Infiniti G37 "are mounted slightly lower" than in the G35 sedan "and offer a greater range of motion," according to Edmunds. They go on to say "this is good news for taller drivers," as the Infiniti 2009 G37's setup affords greater headroom and allows for an even greater opportunity to find a comfortable driving position. Edmunds also comments that "the available sport seats, with their adjustable bolsters, are very comfortable and snugly hold you in place."

The Infiniti 2009 G37 does a wonderful job of reducing road noise. While Automobile Magazine feels that the Infiniti G37's engine isn't "quite as melodic as the [BMW] 335i's twin-turbo straight six," reviewers at Car and Driver claim "the exhaust note is a pleasing burble." Other than the engine note, there will be little noise to disturb drivers in the Infiniti G37.

Despite the lack of crash-test ratings, the 2009 Infiniti G37 scores well due to its excellent safety features.

The 2009 Infiniti G37 comes with a long list of standard safety features; for the even more safety-conscious, Infiniti offers a few optional safety touches as well on the Infiniti G37. However, the 2009 Infiniti G37 has not been crash-tested by either the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS).

Reviews read by TheCarConnection.com praise the selection of standard safety features on the 2009 Infiniti G37. Cars.com says that "active head restraints" and "four-wheel-disc antilock brakes" are standard on this Infiniti 2009 G37. Edmunds reviewers note, "all 2009 Infiniti G37s come standard with stability control, traction control, front-seat side airbags," and "full-length curtain airbags."

When it comes to optional safety features ForbesAutos reports, "a Preview Braking function is included with the optional laser-guided Intelligent Cruise Control that automatically pre-pressurizes the brake lines in anticipation of a panic stop." Edmunds says other safety features are available on the "optional Technology Package," which includes "adaptive headlights and front seatbelts that can better prepare for front occupant safety if a collision is anticipated."

A sometimes overlooked but important feature of every automobile is visibility, and the G37 has plenty of it. Cars.com reviewers are quick to point out that although the Infiniti G37 has a "low riding seating position," the generously sized windows help maintain good overall visibility. Edmunds adds that the optional "adaptive headlights" can swivel into a turn, further increasing night driving safety in this Infiniti 2009 coupe.

Between the lengthy resume of standard features and the impressive array of optional features, the 2009 Infiniti G37 is loaded to the gills.

The features on the 2009 Infiniti G37 are plentiful enough to keep owners happily occupied during long drives.

Reviews read by TheCarConnection.com indicate that "standard features are plentiful," says ForbesAutos. There are a few differences between the three trim levels, but Edmunds mentions that even the base Infiniti G37 comes standard with "bi-xenon headlights, keyless ignition, leather upholstery, eight-way driver and four-way passenger power seats," as well as a "CD/MP3 player with satellite radio." Kelley Blue Book adds that the base model Infiniti 2009 G37 includes a "touch-screen LCD display" that "features an intuitive, visually appealing interface." Moving up to the Journey and Sport 6MT versions of the Infiniti G37, Edmunds states that the "Journey trim adds an eight-way power passenger seat, dual-zone automatic climate control and an in-dash six-CD changer," while the Infiniti 2009 Sport 6MT trim of the G37 gets "sport-styled front seats."

When it comes to optional upgrades, the 2009 Infiniti G37 has something to suit anyone's taste. Among the more "noteworthy options," ForbesAutos mentions "a rear-view camera, an 11-speaker Bose 'Studio on Wheels' premium audio system with iPod connectivity," and a "Music Box 9.3-gigabyte digital music storage unit." That is far from the end of the list, though, as Kelley Blue Book reviewers also find that the 2009 Infiniti G37 can be equipped with "Intelligent Cruise Control" and "Bluetooth hands-free cell phone connectivity," along with "a hard drive-based touch-screen navigation system with real-time traffic info." The Intelligent Cruise Control offered on the Infiniti G37 is particularly impressive, and Cars.com reports that it "can match highway speeds with the car ahead," and the system even "preloads the brakes for faster response if the car in front slams on its brakes."
