The Basics:
Don't look to hard for visual differences between the 2012 Infiniti G25 and the mightier G37 Sedans, because there aren't any significant ones on the outside. However under the hood there's a 2.5-liter V-6, making 218 horsepower--a 110-hp deficit versus the G37.
While that might set off warning bells that the G25 is underpowered (by most accounts, it isn't), all the rest of the package remains delightfully the same--with a tight sport suspension, great dynamics and poise, and quite possibly the best steering among sport sedans. Unfortunately, you can't get the G25 with a manual gearbox; it comes only with the seven-speed automatic, which we've noted is an excellent companion with the larger engine in enthusiastic driving but a little lumpy and indecisive around town.
With its smaller engine, the G25 manages somewhat better fuel economy of up to 20 mpg city, 29 highway—that's a mile or two per gallon better than the G37. You won't want to choose the G25 on gas mileage alone, but it could be a good deal for those who want the features, appearance, and handling of the G37 but don't need all the power.
The G25 comes in Base and Journey trims, and in the latter it can be optioned with most of the same luxury and tech features as the G37. Both the G25 and G37 can be had with all-wheel drive—and as such they're called the G25x and G37x.

Other Choices:
- 2012 Acura TL
- 2012 Audi A4
- 2012 BMW 3-Series
Reason Why:
The BMW 3-Series remains the top rival to the G37; it also has great dynamics and near-perfect steering, though our editors like the steering feel of the G37 best. On the other hand, the 3-Series is more refined, composed, and day-to-day livable—especially if you reside in a place with rough roads. The new Audi A4 is another top rival, with its rear-biased Quattro all-wheel-drive system promising more driving enjoyment, plus top-notch materials and a cohesive design inside and out. For those who want a sporty but comfortable choice, the Lexus IS would work; its interior is a bit more cramped and it doesn't feel as sporty overall, but otherwise it's comfortable. The Acura TL is a slight step up in interior space, and in TL-SH guise it can be a lot of fun to drive; however it's somewhat less racy-looking.
The Bottom Line:
Forget that the 2012 Infiniti G Sedans are somewhat practical four-door designs; they can provide all the sensory thrills and dynamic satisfaction of full-fledged sports cars.
