Editor's Overview

With a sporty yet comfortable ride, loads of technology and rear- or all-wheel-drive, the 2012 Infiniti G proves it can run with the best in its class. That it can do so at a lower cost than competitors in the entry-level luxury segment is just icing on the cake.

If you are searching for an entry-level luxury vehicle that delivers thrilling performance and a big bang for your buck, the 2012 Infiniti G series is worth a closer look.

You May Not Like The 2012 INFINITI G25 Sedan If...

The 2012 Infiniti G is a terrific all-around performer, but if we had to nitpick, notable grievances would include the V6 engine’s excessive thirst for fuel and the coupe/convertible’s meager rear seat headroom. Additionally, if you obsess over "communicative steering feel," the BMW 3 Series deserves consideration.

What's New

The 2012 Infiniti G sedan offers a new Malbec Black exterior color. The G37 sedan also receives various updates to its Limited and Sport Appearance editions, including a new graphite interior color, 18-inch alloy wheels and Black Obsidian exterior color for the Limited Edition and a new black grille for the Sport Appearance Edition.

Interior Features

The 2012 Infiniti G’s interior is exceptional both in design and in the quality of materials used. The luxurious cabin is marked by supple leather-trimmed seating surfaces and elegant Shodo aluminum trim inspired by a form of Japanese calligraphy. The form-fitting standard driver’s seat features 8-way power adjustability, while sport models offer increased support with power-adjustable bolsters and a thigh extension function. Adding to the Infiniti G’s contemporary architecture is a sharp 7-inch, full-color display. Outward visibility is commendable on the G sedan, however, the coupe and convertible possess high hood line and bulky C-pillars that lightly compromise visibility.

Exterior Features

Every iteration of the Infiniti G series comes wrapped in a well-tailored suit of sleek sheetmetal combined with subtle chrome accents and Infiniti’s signature 4-bar grille design. When night falls, standard bi-xenon headlights and LED taillights provide an upscale, modern look. Both the 2012 Infiniti G37 coupe and convertible offer available 19-inch wheels, while the coupe offers an exclusive high-performance IPL edition featuring aggressive front and rear styling, side sills and rear spoiler.

Driving Impressions

Every Infiniti G possesses dynamic performance credentials that only improve when coupled with the G37 Sport Package. Under normal driving conditions, the G pampers its occupants with an array of high-tech goodies and a comfortable ride. Drive it enthusiastically, and the G satisfies like few competitors can. The G37’s tenacious 3.7-liter V6 pulls strongly on demand, whether mated to the 7-speed automatic or 6-speed manual transmission. If you find the Sport Package-equipped G37 not sporty enough, Infiniti offers a high-performance variant – the IPL – with more power, revised suspension, and larger brakes. All G models benefit from a driver-selectable Vehicle Dynamic Control (VDC) system that allows you to explore a generous portion of the vehicle’s potential before the system intervenes. If you live in a frosty climate, or prefer a little extra traction during spirited driving, we suggest you opt for the Intelligent All-Wheel Drive system.

Pricing Notes

The Manufacturer’s Suggested Retail Price (MSRP) for the 2012 Infiniti G models starts at around $33,000 for the sedan, under $39,000 for the coupe, and mid-$40s for the convertible. The performance-oriented IPL coupe comes in just under $50,000. Those figures make the G a rather attractive choice when compared to its competition – especially those with a German pedigree where opting for similar horsepower and features will end up costing significantly more. The Infiniti G’s advantage gets a bit less well-defined when it comes to residual values. All models retain a solid percentage of their original cost over time. However, while the G’s residual value fares better than the Lincoln MKZ, Mercedes-Benz C-Class, Cadillac CTS and Audi A4, it falls just short of the projected residual values held by the Acura TSX, TL and Audi A5, and far short of the BMW 3 Series and Lexus ES 350.

Notable Equipment

Well-appointed from the start, the Infiniti G series includes leather-trimmed seats, leather-wrapped steering wheel, Infiniti’s Intelligent Key "keyless" entry system – the key never needs to leave your pocket or purse – with push-button start, a 6-speaker audio system with an auxiliary audio jack for MP3 players, dual-zone automatic climate control, 8-way power driver’s seat with a 4-way power passenger’s seat and bi-xenon headlights.

Notable Options

To keep the 2012 G25 sedan a value-based proposition, Infiniti offers only a few options such as a sunroof and splash guards. All G37 models offer an extensive list of optional goodies, including a Bose premium audio system, sonar proximity warning system for those tricky parking spots, hard drive navigation system with 3D building graphics and advanced voice recognition, adaptive cruise control system to help alleviate the frustration associated with highway traffic, sport-tuned suspension, supremely comfortable 12-way power driver’s seat and warm maple interior trim.

Favorite Features

7-inch LCD Information ScreenThe 7-inch touch-screen display found in every Infiniti G features an intuitive, visually appealing interface and serves as the control center for options such as iPod integration, a hard-drive navigation system with real-time traffic and weather info, backup camera, 9.3-gigabyte music hard drive, and a CompactFlash card reader for music.Intelligent Cruise ControlAs a G37 option, Infiniti’s Intelligent Cruise Control system helps maintain a pre-set distance from the vehicle traveling ahead of you. When a vehicle violates the driver’s pre-set parameters, Intelligent Cruise Control will renew the predetermined distance by automatically reducing the vehicle’s speed.

Under the Hood

The G25 sedan is fitted with a 2.5-liter V6 engine and 7-speed automatic transmission. The G37’s robust 3.7-liter V6 is the latest iteration of Nissan’s renowned VQ35-series engine. This all-aluminum engine is loaded with design elements that help reduce internal friction and increase overall performance. Matched with either a 7-speed automatic or close-ratio 6-speed manual transmission, the G37 returns slightly-above-average EPA fuel economy numbers for the class. Revised engine software and a new free-flowing exhaust system enable the IPL coupe to squeeze an extra seven lb-ft of torque and 18 horsepower out of the already impressive 3.7-liter V6.2.5-liter V6218 horsepower @ 6,400187 lb-ft of torque @ 4,800 rpmEPA city/highway fuel economy: 20/29 mpg (RWD), 19/27 mpg (AWD)3.7-liter V6(Sedan – 328 horsepower) (Coupe/Convertible – 330 horsepower) (IPL Coupe – 348 horsepower) @ 7,000 rpm(Sedan – 269 lb-ft of torque) (Coupe/Convertible – 270 lb-ft of torque) (IPL Coupe – 276 lb-ft of torque) @ 5,200 rpmEPA city/highway fuel economy: 17/25 mpg (manual), 19/27 mpg (automatic), 18/25 mpg (AWD, automatic)

Editors' Notes

For 2012, the Infiniti G series continues its tradition of captivating car buyers looking to get what they pay for in entry-level luxury, and then some. The 2012 G offers sedan, coupe, and convertible variants, plus rear-wheel drive (RWD) or all-wheel drive (AWD) and the choice of an efficient 2.5-liter or powerful 3.7-liter V6. The 2012 Infiniti G models have proven once again that they can not only run with the best in their class, they can do so at a lower cost to you.

Infiniti's Great Interior and Fast Pickup

2012 INFINITI G25 Sedan Base

I love the leather interior. For a sedan, the is plenty of room for five passengers. These car drives very smoothly and has great pickup! There are a variety of compartments helps with everything I want. There are 2 things I wish it would do: 1. The cup holders in the back to fold down from the console rather than the backseat. 2. The backseat to fold down to help with hauling items that are longer than the trunk.

- Amanda E

It drives very well in all conditions. It's a g25x model so it has all wheel drive. Exceptional in snow and rainy conditions

2012 INFINITI G25 Sedan

I really like the car. It handles very well and is comfortable. Only issue I have is the gas mileage is not as much as I'd like to be. Very low maintenance on it. Tires are still good. Just had the brakes replaced after 3 years. Plenty of room for small sedan. The color is a pearl white which is very fashionable. The design of the car is excellent. Respond very well to acceleration.

This car is good, not great. Good for the price as a luxury vehicle

2012 INFINITI G25 Sedan Journey Sedan

The interior materials seem slightly less luxurious than comparable luxury vehicles, but the interior is still quite nice. The car is fun to drive and has quality gas mileage along with a sizable gas tank, which means fewer stops at gas stations. My main problem is that the auxiliary audio connection is only compatible with Apple devices.
