The Car Connection Expert Review

Bengt Halvorson Bengt Halvorson Deputy Editor
January 9, 2010

For sport-sedan shoppers who are true driving enthusiasts and willing to sacrifice a little bit of comfort for quick reflexes, the 2010 Infiniti G37 is a great pick.

To bring you a complete set of information on the 2010 Infiniti G37 Sedan, TheCarConnection.com has combed through a wide range of reviews and handpicked highlights in a full review. TheCarConnection.com editors have driven the G37 Sedan and offer their own take for shoppers in this Bottom Line.

Infiniti won't leave a good thing alone, yet it keeps making it better, so we can't complain. The G Sedan was redesigned for 2007, then it picked up a more powerful 3.7-liter V-6 and seven-speed automatic for 2009 (and a name change to G37). Now for 2010, the G37 Sedan already gets a mid-cycle refresh, with a new front and rear appearance, enhanced tech features and options, and a redesigned center console among many small changes.

Overall, the G37's rakish silhouette has remained untouched, and that's a good thing. With a coupelike roofline and a lean, low profile, the G37 flaunts a clean and nicely proportioned profile, with plenty of clean sheetmetal—eschewing the excessive body creases that are so common now. A new front fascia and new-design headlights are paired with a new rear fascia, but you'll have to look closely for the differences from the 2009 model. Most notably, the lower air dam in front gives the G a neater, more measured appearance, but it retains the nice contours around the headlights and grille. The stance remains tasteful yet 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—redesigned for 2010—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 2010 G37 Sedan gets the same 328-horsepower, 3.7-liter V-6 featured in the G37 Coupe. It's mated to a seven-speed automatic transmission or six-speed manual, with all-wheel drive available with the automatic.

Review continues below

The G37 Sedan is one of the most responsive, communicative, and fun-to-drive sport sedans in its class. Its 3.7-liter V-6 makes more muscle—328 horsepower and 269 lb-ft of torque—than some rival V-8s and provides enough thrust to satisfy most rabid performance enthusiasts, though it's a little more raucous than the former 3.5-liter and not nearly as smooth as BMW's excellent turbocharged six in the 335i. The seven-speed automatic transmission in the 2010 Infiniti G37 Sedan pulls off snappy and smooth shifts when accelerating hard, but it seems more at home when driving aggressively; shifts become lumpy and indecisive when light on the throttle. Solid-magnesium steering-wheel paddle shifters (included on G37 Journey and G37x AWD models) command a quick downshift, though, including a throttle blip. Those who like a manual transmission will find the six-speed very satisfying. Underneath there's a firm, sport-tuned four-wheel independent suspension, and power steering adjusts effort according to vehicle speed. The G37 Sedan is quite possibly the best-handling sport sedan, price no object, with great steering feel and near-perfect dynamics, for those who can take advantage of them on the track. Plus, fuel economy is respectable; with the automatic transmission, it now rates 18 mpg city, 26 highway, though TheCarConnection.com fails to meet those estimates.

Seating, cabin space, and ride comfort might be the weakest aspect of the whole 2010 G37 Sedan package. Even the standard seats in the 2010 G37 Sedan have good support, though some might find them a bit too narrow and snug. There's adequate legroom, though headroom is somewhat scarce. The backseat is hardly a place for adults to spend long periods of time—made worse by a shortage of legroom and oddly reclined seatbacks. The backseats don't fold all the way forward to increase trunk space, as they do in many other sedans, but there is a pass-through for skis and such, and trunk space is decent. The interior of the G37 seems sporty and premium yet not lavish—it has the feel of a high-end sports-car cabin more than a sedan, and it's put together tightly. For 2010, trims and finishes have been revamped, and the instrument panel now includes white gauges and a new aluminum trim. Overall, refinement and quiet aren't the reasons for getting a G37, though. The 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.

The G37's quick handling will likely prove to be a safety asset, but there are plenty of other safety positives. Electronic stability control is standard, along with anti-lock brakes with Brake Assist, front side airbags, and side-curtain airbags that cover front and rear outboard occupants. Crash-test ratings for the G37 Sedan have been respectable, with four- and five-star results from the federal government. The IIHS gave the 2009 G37 Sedan top "good" scores for frontal and side impact but hadn't yet renewed them for the revised 2010 model at the time of posting. The only concern with the 2009 model was a "marginal" rating in the IIHS's seat-based rear-impact test.

Four different models of the G37 remain on offer: Base, Journey, Sport, and the G37x AWD. Base models have power driver and passenger power seats, in addition to a long list of popular features. The Journey model now gets more tech features, including a Bluetooth hands-free interface, a rearview monitor, and heated seats and mirrors, plus dual-zone climate control. From the Journey, you can add any number of tech options, including Adaptive Front Lighting and the Intelligent Cruise Control with a Preview Braking safety feature. Features newly added for 2010 include an audiophile Infiniti Studio on Wheels system by Bose, and there's an optional next-generation hard-drive-based navigation system with higher-resolution screen, Zagat restaurant ratings and reviews, XM Weather and XM NavTraffic, and live rerouting. Also available is a new Advanced Climate Control System (ACCS), which purifies inside air and automatically shuts off outside air when exhaust fumes are detected.

2010 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.

Styling

Clean, flowing, and somehow simultaneously conservative yet dashing, the design of the 2010 Infiniti G37 Sedan should appeal to almost anyone.

Overall, the G37's rakish silhouette has remained untouched, and that's a good thing. With a coupelike roofline and a lean, low profile, the G37 flaunts a clean and nicely proportioned profile, with plenty of clean sheetmetal—eschewing the excessive body creases that are so common now. A new front fascia and new-design headlights are paired with a new rear fascia, but you'll have to look closely for the differences from the 2009 model. Most notably, the lower air dam in front gives the G a neater, more measured stance, but it retains the nice contours around the headlights and grille.

Reviewers almost unanimously gush over the G37 Sedan's exterior. Car and Driver 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." 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." 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."

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—redesigned for 2010—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.

Curiously, Kelley Blue Book also mentions paper with regard to the interior, noting the "aluminum accent trim textured to resemble traditional Japanese handmade paper." The reviewer warns that the "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."

Performance

If you want a sport sedan that satisfies when driven hard, the 2010 Infiniti G37 Sedan just might be the ticket.  

The G37 Sedan is one of the most responsive, communicative, and fun-to-drive sport sedans in its class. Its 3.7-liter V-6 makes more muscle—328 horsepower and 269 lb-ft of torque—than some rival V-8s and provides enough thrust to satisfy most rabid performance enthusiasts, though it's a little more raucous than the former 3.5-liter and not nearly as smooth as BMW's excellent turbocharged six in the 335i.

Reviewers love the performance from the engine. Edmunds calls the acceleration "fierce," and ConsumerGuide reports that the engine "satisfies at any speed" and makes "passing maneuvers...a breeze." Motor Trend reviewers clock times from 0-60 at just 5.0 seconds, "with the quarter-mile obliterated in just 13.5 sec at 105.3 mph."

The seven-speed automatic transmission in the 2010 Infiniti G37 Sedan pulls off snappy and smooth shifts when accelerating hard, but it seems more at home when driving aggressively; shifts become lumpy and indecisive when light on the throttle. Solid-magnesium steering-wheel paddle shifters (included on G37 Journey and G37x AWD models) command a quick downshift, though, including a throttle blip.

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.

Those who like a manual transmission will find the six-speed very satisfying. Car and Driver also calls the manual transmission "better behaved" than on previous versions, with "throws [that] remain short but high-effort, the latter a trait shared with the clutch."

Fuel economy is respectable in the 2010 Infiniti G37 Sedan; with the automatic transmission, it now rates 18 mpg city, 26 highway, though TheCarConnection.com fails to meet those estimates. With the manual gearbox, the G37 is rated slightly lower, at 17 mpg city and 25 highway, while the AWD version manages 18/25 mpg.

Underneath there's a firm, sport-tuned four-wheel independent suspension, and power steering adjusts effort according to vehicle speed. The G37 Sedan is quite possibly the best-handling sport sedan, price no object, with great steering feel and near-perfect dynamics, for those who can take advantage of them on the track.

"Steering feel is precise and direct," reports ConsumerGuide, adding that the "available Four-Wheel Active-Steer System provides particularly sharp moves." Edmunds also praises the handling and says that the steering wheel is "alive with information." Motor Trend lists some of the 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 declares that the Infiniti G37 Sedan is 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

There backseat isn't very spacious, and there's more cabin noise than in most other luxury-brand sedans, but you don't buy a 2010 Infiniti G37 Sedan for comfort.

Seating, cabin space, and ride comfort might be the weakest aspects of the whole 2010 G37 Sedan package. Even the standard seats in the 2010 G37 Sedan have good support, though some might find them a bit too narrow and snug. There's adequate legroom, though headroom is somewhat scarce. The backseat is hardly a place for adults to spend long periods of time—made worse by a shortage of legroom and oddly reclined seatbacks.

Kelley Blue Book calls the front seats "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 noting that "the seats in Sport models have additional side bolstering to keep occupants planted in fast cornering." But in back the compliments don't hold. 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." Edmunds says that backseat passengers are "treated to a satisfactory amount of headroom and legroom for a sport sedan, though the cushion is rather low."

The backseats don't fold all the way forward to increase trunk space, as they do in many other sedans, but there is a pass-through for skis and such, and trunk space is decent. 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.

ConsumerGuide claims that "assembly quality and most interior materials are on target for the class." Edmunds says 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." The interior of the G37 seems sporty and premium yet not lavish—it conveys the feel of a high-end sports-car cabin more than a sedan, and it's put together tightly. For 2010, trims and finishes have been revamped, and the instrument panel now includes white gauges and a new aluminum trim.

Everything is put together very well. Edmunds deems "fit and finish [is] generally good," while Cars.com notes the numerous "high-quality materials" inside.

Overall, refinement and quiet certainly aren't the reason for getting a G37. The 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. Edmunds reports that they "found road noise to be an issue during highway cruising," and Motor Trend "noticed more noise than [they were] expecting" during their test drives. So does ConsumerGuide, observing that "road noise is evident on coarse surfaces, especially with the tires included on the G37 Sport."

Safety

The 2010 Infiniti G37 Sedan isn't quite perfect with respect to safety tests, but its excellent handling and extensive features are bound to be an asset.  

The G37's quick handling will likely prove to be a safety asset, but there are plenty of other safety positives. Electronic stability control is standard, along with anti-lock brakes with Brake Assist, front side airbags, and side-curtain airbags that cover front and rear outboard occupants.

Crash-test ratings for the G37 Sedan have been respectable, with four- and five-star results from the federal government. The IIHS gave the 2009 G37 Sedan top "good" scores for frontal and side impact but hadn't yet renewed them for the revised 2010 model at the time of posting. The only concern then was a "marginal" rating in the IIHS's seat-based rear-impact test.

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."

Outward visibility is also quite good in the 2010 Infiniti G37. Parking lot maneuvers are aided by the available rearview camera, which helps drivers spot small obstructions behind the Infiniti G37. Edmunds says the "driving position is excellent, with a relatively low cowl that affords a commanding view of the road."

Features

For a performance-focused sport sedan, the 2010 Infiniti G37 Sedan offers quite a few high-tech conveniences and options.

Four different models of the G37 remain on offer: Base, Journey, Sport, and the G37x AWD. Base models have power driver and passenger power seats, in addition to a long list of popular features. The Journey model now gets more tech features, including a Bluetooth hands-free interface, a rearview monitor, and heated seats and mirrors, plus dual-zone climate control.

From the Journey, you can add any number of tech options, including Adaptive Front Lighting and the Intelligent Cruise Control with a Preview Braking safety feature. Features added for 2010 include a new audiophile Infiniti Studio on Wheels system by Bose. Also available is a new Advanced Climate Control System (ACCS), which purifies inside air and automatically shuts off outside air when exhaust fumes are detected.

Kelley Blue Book says that all G37 Sedan models are "exceptionally well appointed," with the reviewer pointing out the long list of power accessories and steering-wheel controls. Other major positives for the interior include, according to ConsumerGuide, "the navigation system itself is refreshingly easy to use, and many audio and climate functions are separate from it." 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." Both of those comments regard the 2009 model, but for 2010, the system includes a higher-resolution screen, Zagat restaurant ratings and reviews, XM Weather and XM NavTraffic, and live rerouting.

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. New with the Premium package for 2010 is 2GB of flash music storage, and the navigation system now includes Bluetooth A2DP audio streaming along with the 9.3GB Music Hard Drive.

2010 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.
