Pointless to get hung up on stock HP ratings IMO. It will come down to how it actually puts power down. For examaple Q50RS and M340i are basically identical in power and real weight. They are within 2 MPH of 1/4 mile trap speeds. But the Bimmer is nearly a second faster to 60 and through the quarter. I feel like this will lean more towards the Bimmer side than the Infiniti's side, but the point is that in the end performance is all that matters.
Nice looking cars, however I figured auto manufacturers would give up on sedans by now, especially pricey "luxury sports" sedans.

Gone but not forgotten: '99 Camaro SS 6MT | '00 Mustang GT 5MT | and a bunch of Maximas and other cars...
Yeah, 355 is at the low end of the ball park but it really all comes down to how underrated the motor is and how much power the tuning companies can find. For instance, Infiniti rates the base 3.0TT at "300hp" but in reality it makes close to that to the wheels and uses the same turbos as the the 400hp red sport version so it's really only a reflash away from around 500hp with some bolt ons.
I've found with most new cars it ultimately comes down to how much power the trans and SH-AWD system can handle and to a lesser extent how understressed the stock turbos are (those are easier to swap out). My guess it they'll have the strengthen the 10 speed for the 354 ft lbs so I really hope they don't cheap out there but I also heard the SH-AWD could barely handle the NA V6 power levels.
