The 2011 Infiniti G37 delivers stellar performance in a rear-drive sedan that is every bit the equal of its European rivals but with all the quality and reliability for which Japanese brands are lauded. Although not as luxuriously appointed as an Audi A4, the G37 easily matches interior quality and design from such cars as the BMW 3 Series, Acura TL and Cadillac CTS. It also offers a roomier rear seat than most European sedans in this class. Powered by the same 3.7-liter engine found in the legendary Nissan 370Z coupe, the G37 offers up exhilarating acceleration, precise steering and cornering on par with the best performance sedans. Toss in enviable reliability, safety and resale records, and it's clear to see why a used Infiniti G37 is the popular choice for those seeking affordable luxury and performance.

What We Like

Razor-sharp handling with the Sport package; comfortable ride; powerful 3.7-liter V6; impressive technology features; roomy rear seat; all-wheel-drive (AWD) option

What We Don't

Drab color choices; base 2.5-liter engine lacks punch; too much hard plastic inside the cabin

Fuel Economy & Engine Specs

The G25 is equipped with a 2.5-liter V6 good for 215 horsepower and 187 lb-ft of torque. A 7-speed automatic is the only transmission choice, although both rear- and all-wheel drive are offered. Fuel economy figures for the G25 sedan are an estimated 20 miles per gallon in the city and 29 mpg on the highway. All-wheel-drive versions attain a slightly lower rating of 19 mpg city/27 mpg hwy.

The G37 employs a robust 3.7-liter V6 developing 328 hp and 269 lb-ft of torque. A 7-speed automatic is standard on the base and AWD models, with the Sport trim offering a 6-speed manual. Environmental Protection Agency estimates for the G37 with the automatic transmission are 19 mpg city/27 mpg hwy. AWD models earn 18 mpg city/25 mpg hwy, while the manual sees figures of 17 mpg city/25 mpg hwy.

Standard Features & Options

The Infiniti G25 sedan is offered in base, Journey and AWD x trims, while the G37 sedan is offered in base, Journey, x and Sport, with AWD offered on all but the G37 Sport trim with the manual transmission.

The G25 features an 8-way power driver's seat and 4-way power passenger seat, 17-inch alloy wheels, full power accessories, a 6-speaker premium audio system with a CD player, automatic climate control, fog lights, HID low-beam headlights, Intelligent Key keyless entry with push-button starting, leather seating surfaces, aluminum interior accents and a tilt-telescopic steering wheel.

The G25x features all the items on the G25 Journey, plus all-wheel drive.

The G37 adds the more-powerful 3.7-liter engine to the G25's standard equipment list.

The G37 Journey adds the 3.7-liter engine to the G25 Journey's equipment list and also offers up two option packages (listed below).

The G37x adds all-wheel drive to the G37 Journey.

The G37 Sport adds 18-in alloy wheels, a sport suspension, a 6-speed manual transmission, upgraded brakes and steering settings, a limited-slip differential, sport seats with driver's-side power lumbar and side bolsters, plus additional styling and ground effects for the grille, bumpers and side trim.

Options for the G25 are limited to a power sunroof.

The G37 can be equipped with the Premium package that adds a power adjustable steering column, a power sunroof, rear park assist and the 10-speaker Studio on Wheels by Bose audio system, plus memory for the driver's seat, mirrors and steering-column position. The Sport Appearance package builds off the Premium package and adds 18-in wheels and a rear spoiler.

The Technology package adds rain-sensing wipers and Intelligent Cruise Control with preview braking, while the Navigation package adds voice-activated navigation with Bluetooth streaming audio, NavTraffic and NavWeather (requires SiriusXM subscription) and a 9.3-gigabyte Music Box hard drive for storing music.

The 2011 G25 and G37 hold excellent resale values, with the G37 holding slightly higher values than its less-powerful sibling. All-wheel-drive models will fetch higher prices in areas where snow is a regular impediment. To get a good idea of the G37's price range, we suggest checking the used-car values at You can also search the Autotrader Classifieds to see what models are currently for sale in your area.


The National Highway Traffic Safety Administration (NHTSA) did not issue any recalls for the 2011 G25 and G37 sedans.

Recall repairs are required by law, even if the vehicle is out of warranty. Your dealer can check to see if the repairs were performed and, if not, will fix the car at no charge to you. You can also check the NHTSA website; simply enter your vehicle's identification number for a list of performed recall repairs.

Safety Ratings & Warranties

The independent Insurance Institute for Highway Safety gives the 2011 Infiniti G37 a Good rating in its moderate-overlap and side-impact tests but only Average ratings in the small-overlap and roof-strength tests.

When new, the G25 and G37 came with a 4-year/60,000-mile basic warranty and 6-year/70,000-mile powertrain warranty. Infiniti also offered a fully transferable extended warranty that could be purchased when the car was new, so be sure to check if the car you're buying has such a warranty. If you buy your G sedan through Infiniti's certified pre-owned (CPO) program, the basic warranty period is extended to 72 months/100,000 miles from the vehicle's in-service date. You can also purchase an additional year of coverage through the CPO program. To qualify, a vehicle must have less than 60,000 miles and be no older than 4 years from its in-service date.

Other Cars to Consider

2011 BMW 3 Series -- The 3 Series delivers slightly better performance than the base G37, although the Sport model is an even match. The 3 Series isn't as well-equipped as the G37, and it will likely cost more -- both to buy and to service.

2011 Audi A4 -- The A4's front-drive layout can't match the G37's rear-drive handling characteristics, although Audi's quattro AWD substantially improves things. The A4 offers a nicer interior, more luxury options and, should you need the added space, an available wagon model.

2011 Lexus ES 350 -- The Lexus ES 350 can't handle or accelerate like a G37 and there is no all-wheel-drive option, but the ES offers a larger interior and more-luxurious interior, a quieter ride and better resale values.

Autotrader's Advice

If you're seeking out the G37 for its performance attributes, the Sport trim with the manual transmission is a rare but desirable model. For most, a G37x Journey with the Premium and Navigation packages will offer a good blend of ride comfort, performance and features. The all-wheel drive doesn't ding fuel economy too badly and improves grip both on dry pavement and snow-covered roads.
