QUICK CHOP:

Nice chop, but I think the frame of grill is little big. BMW is moving towards caved inwards frame...like the CS concept.

^^ That, and this chop doesn't have the sharknose the F10 will have/has

Big ole nostrils on these new BMWs. I hope don't stick out in the wrong way once shown officially.

No, I don't think they will. But I'm just wondering how the front aerodynamics work with this larger and larger grills. Doesn't a bigger front area mean higher CD?

cd is coefficient of drag or drag/square inch, so that is not going to go up with more frontal area. But the total drag should (which is cd x frontal area).

Anyway I don't think the frontal area of these cars are really going up much (not more than the rest of the dimensions), it is just that the grill is taking up more space in the front.

^ Which means, more air intake..and hopefully that'll lead to a come-back of foglights on the M5..

yeah, but if you look at the front, it looks more squared than rounded. If it's more squared, with a bigger frontal area (it looks like the dimensions have gotten bigger) then the cd could suffer. Of course, we don't have the real car in front of us so we can only speculate and argue. That's why I was just asking.

True true Naruto... but overall, this is a 5 series we're talking about here. Drag co-efficients and so forth aren't all that important for this big hunk-a-metal dressed in a spiffy tracksuit. Even for the eventual new M5, the larger kidney grilles, and the more squared frontal area wouldn't make much of a difference. Also, you gotta remind these mules have heavy cladding applies...underneath it all, the 5er could well have a very curvacious face much like the current one.
