My eyes!!! Won't somebody please think of the children!
Those cars look awful. If they have underbody aero why are the covered in all of those aero devices.
If we want to emphasise underbody aero, it should pretty remove top body aero apart from fairly simple wings.
There should be a maximum of two/three planes of the front wing with a 1 plane rear wing. Remove bargeboards and vertical sidepod fins.
Look again, the 2012-14 apec DW12 did have pretty simple wings and they weren't covered in aero devices, a lot of that bodywork was to try and prevent interlocking wheels that can launch cars.
Even with the far more complex 2015 body kits the cars are still following each other pretty closely. Watch the race from Barber Motorsport Park back in April, it's a fast, flowing circuit with little in the way of long straights (like none at all), yet the race was amazing with close racing and plenty of overtaking.
Yeah, active suspension is a no-no; might as well have computer driven cars in that case.
And no spec floors would probably cause them to be banned or limited again soon, like it already happened in the 80s. A spec floor that does the job of reducing turbulence for the following car, coupled with the corresponding reductions of top of the car aero will do the trick and potentially achieve a much better F1 just like that.
Not necissarily, they were able to generate huge downforce levels in the early 80's thanks to sliding skirts sealing the underfloor and, on the Brabhams, an early form of active suspension that lowered the car very close to the track.
If GE is coming back then skirts and active suspension would hav eto be an absolute no-no to avoid ridiculous downforce levels being generated again, and the current underfloor plank woul already limit ride hights anyway. This is why I said open design on the floor, within certain parameters at least, and severly limiting the front wing. As it stands the front wing is very sensitive to turbulant air and it wouldn't take much for teams like Red Bull and Mercedes to develop them to send a vortex down the side of the car and act as a skirt sealing the underfloor since they already try to do it to a small extent already.
Lets face it though, if it happens it's going to get ballsed up since the teams are going to be involved in the regulations. Force India want spec floors for an obvious reason, Red Bull want the front wings enlarged with current comlexity retained for an obvious reason, the infighting will not be helpful.
