2012 Infiniti G37 Performance
This performance review was created when the car was new. Some links may no longer point to an active page.
If you’re in the market for a powerful upscale midsize car to fling around corners, the automotive press says the Infiniti G is one of the best choices available. A potent V6 engine lineup, crisp handling and powerful brakes make the G one of the best performers in the class. One test driver found fault with the manual transmission in the G37 coupe, saying the clutch was touchy.
- "Regardless of engine, however, the G offers an engaging driving experience matched by a scant few competitors." -- Edmunds (sedan)
- "Ride quality is superb, thanks in part to the smaller-diameter, 17-inch wheels that allow for taller tire sidewalls." -- Car and Driver (G25 sedan)
- "Add acceleration out of the curve and the near-perfect weight-balance become obvious, enabling the aggressive driver to carve one corner after another with keen confidence." -- AutoGuide.com (G37 sedan)
- "The G37 convertible is a joy to drive." -- Automobile Magazine (convertible)
Acceleration and Power
The 2012 Infiniti G has a strong V6 engine lineup that reviewers like a lot. A 2.5-liter, 218-horsepower V6 powers the G25 sedan. All G37 models have the same 3.7-liter V6, but each body style has a slightly different power output, with 328 horsepower for the sedan, 330 for the coupe, 325 for the convertible and 348 for the performance-oriented IPL.
All Infiniti G cars are rear-wheel drive, but all-wheel drive is available on all models except the convertible and IPL coupe. The G’s standard transmission is a seven-speed automatic with manual mode. A six-speed manual is available on the IPL, as well as all G37 models in Sport trim.
There are several different fuel economy ratings for the 2012 G lineup, depending on the model. The EPA estimates that the G25 sedan will get 20/29 mpg city/highway, while all-wheel drive G25 sedans should earn 19/27 mpg. The G37 convertible with an automatic transmission gets 17/25 mpg, while manual convertibles get 16/24. The G37 sedan and G37 coupe get 19/27 mpg with an automatic and 17/25 with a manual. Adding all-wheel drive brings the G37 sedan and G37 coupe’s fuel economy to 18/25 mpg.
Test drivers say that even the base G25 model has plenty of power for most drivers, and enthusiasts can go with the IPL coupe if they want to drive really fast. The only slight negative is the manual transmission, which gets dinged for having a touchy clutch.
- "As V6s go, the 2012 Infiniti G25 revs with exceptional smoothness, charging toward its 7,500-rpm redline with none of the coarseness that has crept into the larger-displacement 3.7-liter V6. Acceleration should be satisfactory for many entry-level luxury sport sedan buyers." -- Edmunds (G25 sedan)
- "G37's eager V6 engine satisfies at any speed, regardless of drive wheels. Passing maneuvers are a breeze. Manual-transmission coupes are very quick. However, G37 coupe test cars suffered from touchy clutch take-up and balky shift action. With only 18 more horsepower, the IPL with manual transmission doesn't feel any quicker than other G37 models. The automatic transmission upshifts smoothly, but is sometimes slow to downshift when more power is required." -- Consumer Guide (coupe)
- "The good news is that the G25 delivers a very satisfying driving experience in spite of the 110 hp and 82 lb-ft of torque it cedes to the athletic G37." -- Car and Driver (G25 sedan)
Handling and Braking
Test drivers agree that the 2012 Infiniti G is one of the best handlers in the class. They say it is ideal for twisty roads and has strong brakes. The G has a firm ride, but reviewers think it travels over bumpy roads well. If you’re looking for a car that’s extremely fun to drive, auto critics think the Infiniti G is hard to beat.
- "Dynamically, G Sedans are among the best in this class. These sedans are grippy and agile, with little lean in corners. Steering feel is precise and direct. Braking is strong and secure." -- Consumer Guide (sedan)
- "Handling is also praiseworthy, as the G 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." -- Edmunds
- “I did my standard 100-mph acceleration run on a secluded freeway on-ramp, one that requires some quick braking before a gradual corner, and the brakes seemed well up to the task, with good pedal response.” -- Automobile Magazine (convertible)
- "It still feels light and athletic, and thanks to the new suspension bits, the body stays as flat as Kansas when cornering." -- Car and Driver (IPL coupe)
