Review of the 2011 Infiniti G Sedan

  • Now with a new base model and an even lower price to match, the 2011 Infiniti G Sedan is an even more compelling luxury sedan that offers a lot for your money.

  • Cons

    Road noise; engine noise with G37; interior not as luxurious as European rivals.

  • What's New for 2011

    The Infiniti G Sedan gains a new member to the family for 2011. The newly introduced Infiniti G25 has a smaller, less powerful V6 and fewer standard features, yet there's compensation in the cheaper price tag. To go along with this new entry-level model, the Infiniti G37 has been stripped of its base trim but has gained a pair of special-edition models. Four-wheel active steering has been discontinued.

What's New for 2011

The Infiniti G Sedan gains a new member to the family for 2011. The newly introduced Infiniti G25 has a smaller, less powerful V6 and fewer standard features, yet there's compensation in the cheaper price tag. To go along with this new entry-level model, the Infiniti G37 has been stripped of its base trim but has gained a pair of special-edition models. Four-wheel active steering has been discontinued.


Getting the most bang for your buck is rarely the most important aspect of a luxury car purchase. There's always going to be that unquantifiable X-factor, whether it's styling, perceived quality or the fact that it'll make your brother really jealous. Yet for those who would like to get the most power and the most stuff for the least amount of coin, the Infiniti G Sedan is a go-to choice.

For 2011, the new G25 trim level increases the G sedan's value proposition even further. While the 328-horsepower G37 provides rapid acceleration that similarly priced competitors simply can't match, it might be a case of overkill for many of its customers. To compensate, the 2011 Infiniti G25 features a 218-hp V6 that should prove to be just enough for most while also getting slightly better fuel economy. Thankfully, Infiniti didn't skimp on the equipment, as the G25 Journey trim level comes with the same abundant goodies as are standard on the G37. There will be a base G25, but it exists mostly to achieve an advertisement-friendly price point.

Also shared between both models is the G's engaging driving experience. Power will obviously differ, but the G is renowned for its compelling handling sourced from a platform shared with the Nissan Z car. Opting for the G37's Sport package enhances the G's talent around the corners.

Whether you go with the invigorating G37 or the more frugal G25, the 2011 Infiniti G Sedan indeed provides a lot of bang for your buck in terms of performance, space, luxury, convenience and high-tech features. Some other vehicles in its price range include the 2011 Acura TSX and TL, 2011 Audi A4, 2011 Cadillac CTS, 2011 Hyundai Genesis, Lexus IS and 2011 Mercedes-Benz C-Class, but none offer the same value with such a compelling driving experience as Infiniti's sport sedan.

If value matters less to you, certainly the BMW 3 Series remains the top sport sedan choice, while some of the G's aforementioned competitors give off a more luxurious vibe. Yet whatever your luxury-car X-factor may be, the 2011 Infiniti G25 and G37 are worth your consideration.

Body Styles, Trim Levels, and Options

The 2011 Infiniti G Sedan is available in a number of different trim levels broken into two model designations based on engine: G25 base, G25 Journey, G37 Journey and G37 Sport 6MT (six-speed manual transmission). G25x and G37x models add all-wheel drive to the Journey trims. The G coupe and convertible are reviewed separately.

The base G25 comes well equipped with 17-inch alloy wheels, bi-xenon headlights, foglamps, keyless ignition/entry, cruise control, automatic climate control, an eight-way power driver seat, a four-way power passenger seat, a tilt-and-telescoping steering wheel, leather upholstery and a six-speaker sound system with CD player, satellite radio and an auxiliary audio jack. The G25 Journey adds automatic headlights, heated mirrors, a rearview camera, dual-zone automatic climate control, rear-seat air vents, heated front seats, an eight-way power passenger seat, an auto-dimming rearview mirror, Bluetooth and an iPod/USB interface.

The G37 Journey differs only in the engine department. The G37's Premium package adds rear parking sensors, a sunroof (optional on G25 Journey), power-adjustable steering wheel, driver memory functions and a 10-speaker Bose sound system with digital music storage. The Sport Appearance package adds the Premium items plus a rear spoiler, chin spoiler and 18-inch wheels. The Navigation package adds a hard-drive-based navigation system, real-time traffic and weather, voice controls and additional digital music storage.

The G37 Sport 6MT adds all the Premium and Navigation package items, plus a six-speed manual transmission, a limited-slip differential, different 18-inch wheels, summer performance tires, a sport-tuned suspension, bigger brakes, sporty styling flourishes, sport seats with manual thigh extension and driver power-adjustable thigh and torso bolsters. If you want all this stuff without the manual, opt for the Sport package available on the G37 Journey. The G37 Limited is essentially a loaded Journey with Sport package that also includes a blacked-out grille, unique headlights, special styling flourishes and red leather upholstery. Only 350 will be made.

Powertrains and Performance

The Infiniti G25 is powered by a 2.5-liter V6 that produces 218 hp and 187 pound-feet of torque. A seven-speed automatic is the only transmission. Buyers have a choice between standard rear-wheel drive and optional all-wheel drive (called G25x). Infiniti estimates fuel economy to be 20 mpg city/29 mpg highway for the rear-drive model. The G25x drops to 19/27 mpg.

The Infiniti G37 comes with a 3.7-liter V6 good for 328 hp and 270 lb-ft of torque. A seven-speed automatic is standard, but the Sport 6MT features a six-speed manual transmission. As with the G25, rear-wheel drive is standard and all-wheel drive (G37x) is optional as long as you have the automatic transmission.

In Edmunds performance testing, the G37 Journey went from zero to 60 mph in a rapid 5.4 seconds. The G25 is more modest, with an 8.0-second 0-60 mph time. EPA-estimated fuel economy for the G37 is 19 mpg city/27 mpg highway and 22 mpg combined with the automatic and rear-wheel drive, while the 6MT gets 17/25/20. The G37x returns 18/25/20. The new G25 improves upon these numbers only slightly with a 20/39/23 mpg rating. The G25x drops to 19/27/22.


Every 2011 Infiniti G Sedan comes standard with antilock brakes, stability and traction control, front side airbags and side curtain airbags. A rearview camera is standard on all but the G25 base. In Edmunds brake testing, the G37 Journey came to a stop from 60 mph in a very short 106 feet.

The Infiniti G Sedan has not yet been rated using the government's new, more strenuous 2011 crash testing procedures. According to 2010 ratings, the G Sedan received a perfect five stars in all categories except frontal-impact protection for the front passenger, which got four stars. The Insurance Institute for Highway Safety gives the G the highest rating of "Good" in the frontal-offset and side crash tests.

Interior Design and Special Features

The G37 offers user-friendly controls, excellent build quality and a handsome design -- the latter highlighted by such items as the car's leather-accented magnesium shift paddles and the Japanese "Shodo" aluminum trim (or optional wood trim). Overall materials quality isn't exactly to Audi or Mercedes standards, but you are spending less money. The front seats are comfortable and well-bolstered, while the available sport-styled seats offer even more aggressive bolstering, though they may be a bit too snug for larger drivers. The backseat offers respectable space for this class, with the exception of the narrow center seat.

The G benefits from Infiniti's user-friendly electronics. The iPod interface standard on all but the base G25 is among the best available, while the myriad audio, climate and navigation controls are easy to decipher. The available Bose stereo is particularly impressive as well.

Driving Impressions

As V6s go, the 2011 Infiniti G25's is a smooth revver. It tackles its 7,500-rpm redline with none of the coarseness that has crept into the bigger 3.7-liter V6, owing to the 2.5-liter engine's lighter reciprocating masses. Acceleration should be satisfactory for many entry-level luxury sport sedan buyers.

However, for thrilling acceleration, we'd suggest the G37. We're not fans of the coarse noises it makes at higher engine speeds, but for the money, you can't beat it in this class. The G's handling is also praiseworthy as the sedan attacks curves with aggression and precision, yet remains poised and compliant when driven over less-than-perfect pavement. Think of it as a world-class athlete in evening wear. Steering feel is commendable, particularly with the Sport package's quicker steering ratio. This setup provides excellent feedback and a pleasant weightiness that builds progressively when cornering.

The seven-speed automatic transmission is mostly faultless. Quick gearchanges are at your fingertips via the steering-wheel-mounted paddle shifters, and downshifts are executed with precise throttle blips to match revs. In testing, however, we've noticed that upshifts, even when in Drive, aren't as smooth as they should be for this class of car. Even so, this automatic makes a strong case for itself versus the optional six-speed manual, which has a pleasing bolt-action feel through the gates but is hampered by abrupt clutch engagement.

G25 sedan: a devil in

by on
Vehicle: 2011 Infiniti G Sedan G25 Journey 4dr Sedan (2.5 6cyl 7A)

I bought my G25 sedan almost a year ago with 26k. Within a week, had to take it to the dealer for condensation in one of the headlights. The dealer replaced it, covered under warranty. Now just within the past month, I've had to bring it back to the dealer twice. Once for the chrome trim peeling on the center console lid and then again for a rattle in the dash/ rattle in front passenger door and broken cupholder. Once again, the dealer did all work covered under warranty. Normally I would be just disgusted with a car that gave me these build quality issues, but for some reason I seem to fall in love with my G all over again every time I get it back from being in the new Q50 service loaner!!

Rattles, lack of interior storage

by on
Vehicle: 2011 Infiniti G Sedan G37 Journey 4dr Sedan (3.7L 6cyl 7A)

Bought September 2010, now has less than 4000 miles on it. Everything is fine except the rattles from the rear window area. I took it to the dealership once, but nothing has been solved. The rattles are not too bad, but still, it is definitely something prevents me from enjoying this car. Don't know whether another people have this problem or I am just unfortunate. Also, the interior storage is kinda insufficient. Overall, the rattles really ruins my confidence in buying another infiniti.

Exellent chasis, confused powertrain

by on
Vehicle: 2011 Infiniti G Sedan G37 Journey 4dr Sedan (3.7L 6cyl 7A)

I have the regualr, non-sport G37 with stick 17 wheels, and the car is still very sporty, very neutral. At the same time the ride is well composed and smooth. Interior quality is good but not great. Its about on par with my VW GTI in terms material quality for the dash and all the nobs. The fake wood ook good but I've seen better. Leather is fine, but again not the best. Layout is very logical though. Interior room is also fine, but a little less that I expected for a vehicle this size. Considering the my other car, a VW GTI, which is some 20 in shorter has nearly as much front and backseat room... I will describe the power-train in suggested improvements page.

Glad i bought the g37

by on
Vehicle: 2011 Infiniti G Sedan G37 Journey 4dr Sedan (3.7L 6cyl 7A)

I've been looking at cars off and on for a few months and the G37, Volvo S60, Maxima, and Genesis were on the list. Genesis was too large and I wasn't sold on the CVT in the Maxima. After driving the S60 and G37 back-to-back, I went with the G with the Premium package. Handling was a little sharper than the S60 and power is effortless. Plenty of features. The car is fun to drive. The ride is firm and on the sporty side, so if you want a softer ride, look at a Lexus. A G wants to be driven but will provide plenty of creature comforts at the same time.

Confident: g37 sedan is definitely

by on
Vehicle: 2011 Infiniti G Sedan G37 Journey 4dr Sedan (3.7L 6cyl 7A)

Before making my decision on G37 Sedan, I carefully researched BMW 335i, Audi A4, Lexus IS350, the G37 Coupe (330HP). My pricing range is in between 35K - 45K. After test drove all these cars, I have to choose G37 sedan because it's a mix of quality and stylish and power. Most importantly, you could feel the car has built very solid, the engine makes you feel powerful, and confident on the street. While 335i has twin turbo but unfortunely tons of problems. Both A4 and IS350 lack of power. The G37 Coupe version is nice, but it's a bit heavier than the Sedan. also only 2 HP more than the sedan, I would recommend you getting Sedan not only I have one, but it's a better value by far.

Love it!

Vehicle: 2011 Infiniti G Sedan G25x 4dr Sedan AWD (2.5 6cyl 7A)

My lease was ending on my 08 Sentra and I immediately thought of Infiniti. Went to my dealer and test drove the G35 but it wasn't for me. My salesman then showed me the 25x and that was it. No question! Its doesn't come with Navi but with an iPhone or any smart phone Navi is obsolete. This car is definitely a head turner, love the interior, super comfortable, great back up camera and the dash is awesome. The only thing that I don't like is the loud growl it makes when you take off, its slightly intimidating but then again I've only had her for a week so I'm sure I will get used to it in time. Hate driving in the snow but I'm sure this winter I won't mind.
