Firstly, having the floor just wider than the sidepods, means the turbulence from the front wheels can be directed away from the sidepods by the airflow conditioners, mounted round the sidepods. Without that turbulence, the deep undercut of the sidepod can direct the airflow away from the rear tyres, toward the rear of the car and over the diffuser. Secondly, F1 cars aren't ground effect and therefore low pressure created under the car will try to pull the air flow in underneath the floor, reducing the performance of the diffuser. The vanes or slots, that have appeared on the outer rear edge of the floor, prevent the air from going underneath, sealing that area like a skirt and improving the overall performance of the diffuser. Thirdly, the rotation of the rear tyres on the track surface, causes the airflow to be displaced round that area of the car. However, the displaced air pulls the airflow across the top of the floor, through the vanes and out around the outside of the tyre contact patch. |

my issue is more the size of the divide and think solutions should be aimed at reducing this gap. if its about big business, then FOM has an obligation that the participants are all of sufficient size to compete as a big team. maybe that means a fairer distribution of prize money or budget/resource allocation caps but without this mechanism im of the belief any other changes (to design etc) will not have the indented results of closer competition. granted F1 has many more moving parts (so comparisons o other sports often prove ineffective) but other sports (mainly N.American sports) seem to recognize the necessity of financially equalized playing fields as a starting point. Europe, or soccer in this case, went the other way and created a league for the stupidly rich teams. matter of preference (or bias i guess) but i like a n.american approach more. Quote:

Having the teams set their own rules is really a very poor idea...They always try to protect the status quo and their accumulated advantages (e.g., keeping the ratio of front and rear tyre width the same in 2017, keeping the relative width of front wing to front wheels the same in 2017 too), instead of starting afresh with a well considered set of all-new regulations for all-new concept cars. |

I thought the Mexico track was fine. You can't overtake in long fast corners, for the most part. Tight corners are better for sharp, decisive moves under brakes.

It seemed that cars like the Lotus 88 were entirely the opposite of that. |

But none of the esses section provides any sort of run at another car, or a decent braking zone. So sharpening off that section of the track did nothing but ruin the flow and make every corner the same.

Actually yes. I'm probably thinkng that the bodywork needed to extend the length rather than the width. Nonetheless if a floor has nothing on it, it becomes a flat plane aerodynamic surface.

If they were not allowed to extend the floor beyond the bodywork, and if you were further not allowed to use conditioning strakes and vortex generators on said floor, then you could not spend money (how much must this thing have cost!) on generating downforce there.

This was an interesting article too, and shows just how far aero development has gone, Mercedes' answer to blown axles, blown wheels, different set for every track.

Alternatively I read the other day that the Mexican president (elect?) has taken a dim view of a major new airport being built just outside the city and has cancelled the construction preferring upgrades to the existing airport and a smaller one south of the city. However foundations for the new site had been laid at some huge cost already and the site will need to be turned into something else, so perhaps this could form the basis of a new circuit/sports/entertainments complex. |

Not disputing the legality, just the unecessary complication and bad drafting of the rules to allow this type of aero extravagance.
How badly must this be affected when the airflow goes from linear to turbulent? |

The Lotus 88 was a ground effect car. It had two chassis, with the cockpit in the inner chassis and independently sprung from the outer one, which was one ground effect system. I remember it causing a lot of controversy at the time and it got banned.

Truly innovative "outside the box" well, actually, more outside one box, inside another. Real genius, exactly what F1 should be about. If it's within the rules, don't immediately change them. How else could "garagistes" stand an earthly?

I feel like we're going in circles here (which is what motorsport is, in a nutshell!)
The rules are too restrictive. We want fewer rules. We want innovation. The way the teams use the floor is very silly. That should be regulated. So..more restrictions? The cars are thinner than the floor width, not because the regulations dictate they have to be thin, but rather than is the optimal solution. The cars smaller and creating a smaller hole in the air. So do you want the teams finding innovative solutions, or more rules and restrictions? |

Indeed but the Williams FW07 was more in my mind although again the pods don't extend to the extremity of the wheels. |
