The 2011 Infiniti G Sedans remain one of the top choices driving enthusiasts willing to sacrifice a little comfort for responsiveness and poise.

While the longtime, no-brainer choice for enthusiasts looking for a satisfying sport sedan is the BMW 3-Series, the 3er's most formidable rival is the Infiniti G37 Sedan. In some respects, it feels like a true sports car, with excellent steering, dynamics, and poise, along with strong powertrain performance from its 328-horsepower V-6 and six- and seven-speed transmissions. And for 2011, Infiniti has added a lower-priced, somewhat more fuel-efficient G25 model that substitutes in a smaller-displacement V-6 but doesn't mess with a good thing otherwise.

The G37 is, to a wide range of eyes, one of the best-looking sport sedans on the market. Clean and nicely proportioned, with a coupelike profile, the G37 skips sharply creased sheetmetal in favor of a smooth, contoured look. The stance remains tasteful yet aggressive and sporty, and you'd be hard-pressed to find any difference in appearance between the G37 Sedan and the new G25 Sedan other than badging. Inside, the G Sedans keep with sport-sedan tradition, offering the cockpit feel of a sports coupe, with a full-length center console and rather low seating position.

Our editors haven't yet driven the G25, which gets a new 218-hp, 2.5-liter V-6 and is being offered as both a price leader for the sport-sedan line. In any case, the G37 is one of the most responsive, communicative, and fun-to-drive sport sedans in its class. Infiniti's 3.7-liter V-6 makes more muscle 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. While shift quality with the seven-speed automatic transmission in the 2011 Infiniti G37 Sedan (the only transmission in the G25) is somewhat lumpy and indecisive in gentle driving, it becomes snappy and smooth when accelerating hard.

The G is also quite possibly the best-handling sport sedan, price no object. Even on less-than-perfect surfaces, the suspension is hard to fluster and brakes are stout. And with great steering feel and near-perfect dynamics, and that provides both reassuring safety and poise on the road, as well as thrills for those who pay for track time.

The weak link of the G Sedan's package for many might be seating, cabin space, and general refinement and ride comfort. The G Sedan's cabin has a feel that's more like that of a high-end sports car than a luxury sedan; it's sporty and premium but not at all lavish. But fit and finish are top-notch and trims have been upgraded in recent years. Overall, the G Sedan rides more like a sport coupe as well; while it's not downright jarring, a lot of road noise makes it inside. Additionally, the G37's engine is significantly more coarse—both vocally, and in terms of vibration—than other rival engines.

In addition to the three models of the G37—Journey, Sport, and G37x AWD—the new G25 is offered in Base, Journey, and G25x guises. Going with the G25 doesn't give up much, other than 110 horsepower and a lot of torque. Base models, whether G25 or G37, get standard leather upholstery, power front seats, automatic climate control, a six-speaker audio system, and XM satellite radio.

The Journey model adds 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. An audiophile Infiniti Studio on Wheels system by Bose is optional, as is 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.

Styling

The design of the G37 Sedan is conservative yet dashing—and even a little sexy—making it one of the most universally good-looking sport sedans.

The G37 is, to a wide range of eyes, one of the best-looking sport sedans on the market. Clean and nicely proportioned, with a coupelike profile, the G37 skips sharply creased sheetmetal in favor of a smooth, contoured look.

Inside, the G Sedans keep with sport-sedan tradition, offering the cockpit feel of a sports coupe, with a full-length center console and rather low seating position. Top and center, a screen (and supplemental controls beneath) accesses audio and climate functions. A strong beltline wraps around to the doors, while big, round dials in a hooded gauge cluster set a sporty tone.

Performance

The 2011 Infiniti G37

Carried over from last year is a 328-horsepower, 3.7-liter V-6 in the G37, with either a seven-speed automatic transmission or six-speed manual. What's new this year is the 2011 Infiniti G25 sedan, which offers a smaller, 2.5-liter V-6, making 218 horsepower and hooked up only to the seven-speed automatic.

Our editors haven't yet driven the G25, which is being offered as both a price leader for the sport-sedan line as well as a slightly more fuel-efficient option, we've spent lots of time in the G37 Sedan. It's one of the most responsive, communicative, and fun-to-drive sport sedans in its class. Infiniti's 3.7-liter V-6 makes more muscle 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.

While shift quality with the seven-speed automatic transmission in the 2011 Infiniti G37 Sedan (the only transmission in the G25) is somewhat lumpy and indecisive in gentle driving, it becomes snappy and smooth when accelerating hard—and seems more at home when driving aggressively, with a satisfying throttle blip delivered when managing shift with the solid magnesium paddle-shifters (included on G37 Journey and G37x AWD models). Otherwise, the six-speed manual in the G37 is very satisfying.

The G is quite possibly the best-handling sport sedan, price no object. Even on less-than-perfect surfaces, the suspension is hard to fluster and brakes are stout. And with great steering feel and near-perfect dynamics, and that provides both reassuring safety and poise on the road, as well as thrills for those who pay for track time.

2011 INFINITI G37 Sedan

Comfort & Quality

The 2011 Infiniti G37 Sedan has a snug cockpit feel that some will like, but if you want an especially quiet, refined luxury sedan it's not the right pick.

While the G Sedan has the looks and segment-leading athleticism, the weak link of the G Sedan's package might be seating, cabin space, and general refinement and ride comfort. The front seats of the G 37 Sedan are nicely contoured, but they can be a bit too narrow or snug for some. 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. In back, the seatbacks don't fold forward as they do in many sport sedans, but there's a pass-through for skis and such, and trunk space is decent.

The G Sedan's cabin has a feel that's more like that of a high-end sports car than a luxury sedan; it's sporty and premium but not at all lavish. But fit and finish are top-notch and trims have been upgraded in recent years. Overall, the G Sedan rides more like a sport coupe as well; while it's not downright jarring, a lot of road noise makes it inside. Additionally, the G37's engine is significantly more coarse—both vocally, and in terms of vibration—than other rival engines.

Safety

The 2011 Infiniti G Sedans have all the expected safety features—including crisp handling—but its ratings aren't perfect.

The 2011 Infiniti G37 has a lot going for it in terms of safety—including its excellent handling—but it's not altogether a perfect pick.

Electronic stability control is standard on the G37, 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 in last year's tests, but the G Sedans still haven't been tested in the new, more rigorous NCAP program introduced for 2011.

The 2011 G37 Sedan retains top 'good' scores for frontal and side impact from the Insurance Institute for Highway Safety (IIHS), but some might have some concern about its 'marginal' rating in the seat-based rear impact test, which could indicate a higher chance of whiplash or neck injury.

Features

The 2011 Infiniti G Sedans offer a good roster of performance equipment and convenience features.

In addition to the three models of the G37—Journey, Sport, and G37x AWD—the new G25 is offered in Base, Journey, and G25x guises.

Going with the G25 doesn't give up much, other than 110 horsepower and a lot of torque. Base models, whether G25 or G37, get standard leather upholstery, power front seats, automatic climate control, a six-speaker audio system, and XM satellite radio.

The Journey model adds 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.

An audiophile Infiniti Studio on Wheels system by Bose is optional, as is 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.

Infiniti G37 Sedan Sport models are focused toward the most demanding enthusiast customers—and probably those who plan track time—so they 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.

Fuel Economy

With the addition of the 2011 Infiniti G25, the G Sedans are a slightly greener pick than before—but they're still not very fuel-efficient.

With respect to fuel economy, the G25 and G37 are about par in their class of sport sedans. The new Infiniti G25 models, in exchange for a less power from its smaller-displacement V-6, gain a mile or two per gallon, at 19 or 20 in the city and 27 or 29 on the highway. And the seven-speed automatic gets good numbers; models with the manual gearbox are actually the least fuel-efficient, at 17/25.
