Clearly the G25 is not as quick as the G37, but it still sounds fast, thanks to Nissan's not-terribly-refined VQ-series engine. Nor does this car feel sluggish, and it should have more than enough power to satisfy the needs of many small-luxury-car buyers.
I know from having driven a BMW 328i back-to-back with this car that I prefer the Bimmer, but the G25 nonetheless stands tall on its own; the Infiniti is a very impressive car and a very smart buy. The all-wheel-drive option is highly useful for northern climes, too, and the heated seats made it quite pleasant for my 10-degree drive to work. This generation of the G was introduced several years ago, but its design, both inside and out, has aged quite well.
Compared with the G37, the G25's EPA fuel economy is 20/29 mpg city/highway versus 19/27 mpg (AWD models are rated at 19/27 mpg and 18/25). That smallish difference, along with the minimal $2600 price discount, would make me hard-pressed to turn down the G37's 110-hp advantage.
