I have not seen high res close ups near the rear, but the photos I have seen are crazy. Look how narrow they have gotten the engine cover! The packaging of the engine & gearbox is crazy tight at the rear end. Image 5 is a good one
here to show what I mean.
It also appears that their mirror mounts have been used as a turning vane, intersting. Very bulbous sidepods as well.
The front wings are just hideous at this point. They are massive. It is a VERY clean looking car, very tightly packaged. I do not like the rear wings though. Too skinny for the height.
I hope Ferrari can dominate this year. I think BMW is going to have a pretty good package though as will McLaren & Renault.
