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 sporty and aggressive.

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.

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.

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 its crisp exterior styling. Kelley Blue Book adds the G37's sporting character shows in its tailored sheetmetal and attention-getting grille. Edmunds reviewers find distinction in the G37, from its swoopy styling outside to "Washi" aluminum trim inside.

The G37's interior envelopes drivers and front-seat passengers with low seats, narrow footwells, and an extrudent center console wrapping its way between the two front seats as it makes its way aft. The instrument panel houses large, round gauges placed perfectly in the driver's line of sight, while its infotainment screen mounted front and center on the dash allows easy access to audio and climate functions for drivers and passengers alike.

Kelley Blue Book says the interior controls are arranged in a logical manner and gauges are easy to read, but some buyers may find the cockpit-like interior a bit busy.

2010 INFINITI G37 Sedan

Performance

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

The Infiniti G37 sedan is one of the most fun-to-drive entries in the segment, delivering communicative and responsible dynamics with top-notch V-6 muscle.

The G37 Sedan gets its power from a 3.7-liter VQ-series V6, good for 328 horsepower and 269 pound-feet of torque, more than some rival V-8s and enough to satiate most enthusiasts. However, the now-larger mill is a little more raucous than the former 3.5-liter V-6 and not nearly as smooth as the BMW 335i's inline turbocharged six.

Still, reviewers have fallen in love with the Infiniti's engine performance, with Edmunds noting its fierce acceleration and ConsumerGuide stating it satisfies drivers at any speed by making passing maneuvers a breeze. In Motor Trend's performance testing, the G37 performed the 0-60 mph sprint in 5 seconds flat and it "obliterated" the quarter-mile in 13.5 seconds with a top speed of 105.3 mph.

While the Infiniti G37 is offered with a manual, the available seven-speed automatic is snappy and smooth under hard acceleration. Unfortunately, its shifts lose their crisp nature under light throttle. At least you can take control through the G37's optional steering wheel-mounted paddle shifters made of solid magnesium. Quick downshifts through the paddles are met with a nice blip of the throttle as the engine matches revs.

Reviewers have criticised both transmissions, but most reserve their ire for the automatic. Edmund cautions the automatic's upshifts aren't near as smooth as they should be, even in Drive. In more aggressive driving modes, "you've got yourself a veritable Lurch-o-Matic," it says. That sentiment is echoed by Car and Driver, which focuses on rough, slow upshifts in the automatic's manual mode. Conversely, ConsumerGuide finds the seven-speed automatic to be responsive, smooth, and alert, but a bit busy at times.

If you prefer to row your own, you're in luck as the six-speed delivers a satisfying experience. Car and Driver says its better behaved than previous manual boxes while still retaining short throws. On the negative side, it does make note of the high effort involved in those throws and the heavy clutch.

The 2010 Infiniti G37 is more economically friendly when equipped with the automatic versus the manual. Automatic models are rated by the EPA at 18 mpg city, 26 mpg highway when paired with rear-wheel drive and 18/25 mpg when sending power to all four wheels. Opting for the manual, estimates drop 1 mpg versus the rear-wheel-drive automatic model on each measure to 17 mpg city, 25 mpg highway

Bringing the package together is the Infiniti G37's superb chassis that makes one of the best handling sport sedans on the market today. A sport-tuned independent suspension works its magic at all four wheels. Power steering adjusts weight depending on vehicle speed.

ConsumerGuide reports the Infiniti G37's steering is direct and precise, adding that available four-wheel steering adds some nimbleness to its already sharp moves. Edmunds found the steering provided excellent feedback while Motor Trend notes the G37 is a step quicker than the G35, delivering balance, a taut ride, and an eagerness to step the rear out for some fun. Bringing everything to a stop are strong and secure brakes, says ConsumerGuide. Kelley Blue Book didn't hold back, saying the G37 Sedan is a marvel of suspension engineering that equally impresses when driven hard or normally.

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. Standard seats in the 2010 G37 Sedan provide good support, but 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 finds the eight-way driver and four-way passenger power seats to be supportive and comfortable, with other generally agreeing. Even the seats fitted to Sport models bring additional bolstering to keep you in place under hard cornering. But the Infiniti's backseat is far from marvelous, warn Kelley Blue Book reviewers, stating it can only fit two adult passengers comfortably despite its three seatbelts. Edmunds found head and legroom in the sport sedan to be satisfactory, but its bottom cushion is mounted 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. Without the flip-down seat, trunk space is particularly large with 13.5 cubic feet of cargo volume, but Edmunds says its intelligent shape makes it "surprisingly capacious." Inside the cabin, ConsumerGuide criticizes a lack of small-item storage, remarking it's "just fair."

Reviewers generally agree the Infiniti's interior assembly and material quality is up to par for its class, but Edmunds points out some textured plastic pieces and an insubstantial-feeling overhead map-light housing feel a class below. 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.

Overall, refinement and quiet certainly aren't reasons for getting a G37. It's ride is firm and there's an appreciable increase in road noise in the G37 versus other sport sedans. Both Edmunds and Motor Trend noticed more road noise than expected, especially on highway drives. ConsumerGuide reports its even more noticeable in 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. All models get stability control, anti-lock brakes, front side airbags, and side-curtain airbags as standard equipment.

The IIHS gave the 2009 Infiniti G37 Sedan "good" scores for front and side crash tests but hadn't yet renewed them for the revised 2010 model at the time of posting. IIHS' only concern is a "marginal" score in the IIHS's seat-based rear-impact test.

Cars.com notes the Infiniti can be equipped with a marvel feature as part of its braking system. The G37 will preload the braking system for increased response if it senses a car in front suddenly decelerates.

Thanks to a relatively low cowl and beltline, Edmunds finds the G37 provides "a commanding view of the road," which also makes the sedan easy to park. Further aiding parking spot navigation is an available rearview camera.

Features

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

Infiniti offers the G37 in four different flavors: 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, heated mirrors and seats, and dual-zone climate control.

From the Journey, you can add any number of tech options, including Adaptive Front Lighting and Intelligent Cruise Control with 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.

An available Premium Package brings a moonroof, upgraded Bose audio, power tilt/telescopic steering, Bluetooth, and other options, reports Kelley Blue Book. 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.

Those wanting Intelligent Cruise Control and adaptive front lighting will need to opt for the Technology Package.

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.
