Expert Quotes:
There's no discernible difference in steering weight and feedback or suspension damping.
Edmunds' Inside Line
True, the G25 will never catch a G37 in a drag race. But if we judge performance on sound alone, if we could choose one engine over the other to listen to—we'd pick the G25's 2.5-liter V6.

Braking, steering and handling performance remain pure Infiniti – always impressing

the G25 drives pretty much how it could be expected to -- like a G37 that's down more than 100 horsepower and just under 100 pound-feet of torque.

snappy braking and crisp cornering that keep it among top-tier sports sedans

If you want a sport sedan that's responsive communicative, and fun to drive, the 2013 G37 remains one of the best picks. Even though several of its alternatives have recently been refreshed or redesigned, it holds the crown in sheer fun behind the wheel, due to its near-ideal weight distribution, precise and well-weighted steering, and a suspension tune that helps it feel fleet-footed.
The smaller 2.5-liter V-6 that made its debut for last year in the G25 has already been discontinued. That leaves the 328-horsepower, 3.7-liter V-6 in G37 models as the only engine--available with manual or automatic transmissions and with rear-wheel drive or all-wheel drive. The seven-speed automatic transmission seems to have two personalities, we've noted. It's a little lumpy and indecisive in gentle driving, yet it becomes snappy and actually smoother under harder acceleration; it also includes magnesium paddle-shifters and a smart throttle blip for downshifts. The six-speed manual gearbox is also a good pick.
Engine power is strong in either case, although we add a big asterisk for refinement; the V-6 is a raucous engine, with a coarseness that enters the cabin and a surprising level of engine noise.
Suspension tuning is superb, however. This might just be the best-handling sport sedan, and it's hard to fluster even when pavement surfaces are less than perfect; the quick-ratio steering unwinds predictably and it transmits some surface feedback; brakes are stout and strong; and there's a balanced, seat-of-the-pants feel to hustling the G37 through the corners.
Conclusion
Even the most demanding driving enthusiasts should be happy with the 2013 Infiniti G37.
