Proposed 'shield', halo alternative, unveiled
Discussion

The cars of 1980/81/82 ran fairly small wings because they were getting most of their downforce from side pods and underfloor.
They even tried running cars with no front wings -
The best ground effect cars ran with no front wing, the ones with a front wing were not using them as traditional wings, they are trim devices to alter the balance by altering the flow of air to the tunnels. To make them work you have to have a constant seal between the tunnel sides and the race track surface, which is why they used sliding and then flexible skirts with rubbing strips.They even tried running cars with no front wings -
When the seal is broken you lose about 30% of the downforce and the balance shifts to the rear, which is why on the historic ground effect cars you now see front wings on cars that never ran them in period, as they have to run with a minimum 40mm ground clearance.
The sidepods on the 83 cars are just a function of having to carry cooling devices. The ruling change was to only allow a flat floor on the car between the wheel centre lines, so the sidepods don't have any aerodynamic underside, they are flat.
You saw the first proper diffusers appear in 83 which start at the rear wheel centre. Rear wing can be 100mm higher but is 100mm narrower than 82. They used much larger main elements to produce more wing generated downforce, but also more drag.
The suspension was much softer now the cars didn't need to support so much downforce.
The new rules really hindered the normally aspirated cars because the turbo cars just kept piling on bigger wings as the power climbed. On a ground effect car you generate much lower drag for the same downforce, so power wasn't as big a differentiator.
The area the normally aspirated cars benefited in 83 was through a drop in minimum weight of 40kg compared to 82, the turbo cars couldn't get down there and they also needed to carry more fuel. That helped on the slower circuits which is why the NA cars still won sometimes.

The fia need to fit this to a tub and turn it upside down just to see how a driver could get out because I very much doubt he could, have they even tried this........probably not even though they bang on about being upside down with a fully enclosed cockpit. Remember wehrlein in Monaco, probably never happen again but how would he get out with the halo in the way, the roll hoop was hard up against the tyre wall

Wehrlein couldn't get out anyway, so that's rather a poor example.

I can't recall any modern era F1 car ending arse up but would imagine the driver unable to extract himself until it is righted anyway.
Really? Theres plenty. Brundle and Alonso at Melbourne are first that spring to mind. Plus Barichello at Imola.Edited by handsomeBwonderful on Wednesday 26th July 10:22

About all they can do is paint it.
It depends on how rigidly-defined it is. If it is a part that must be used "as is" like the HANS device then, yes, you are right. If it is a set of regulations, like the car's monocoque safety cell, where it must be able to pass a test, then there is more scope for variance.

maybe....just maybe.....
... they are trying to slowly kill off F1....crummy sounding engines...........cars which still after much analysis look less dramatic than years and years ago, 70s, 80s, 90s, 00s.....................and now the halo
Formula E is gaining momentum........what will be happening in 5-10 years?...........maybe its better to kill it off before FE overtakes and becomes the 'pinnacle'......
but seriously....Im coming around to the halo idea...perhaps the teams can figure out innovative solutions..........sure

as well as teardrop covers some teams may add a gurney flap on top to create some downforce.
Almost certainly. They will want to manage the airflow into the air box. Frankly, I don't think they will look worse than any of the other weird things we've had over the years, like side pod winglets, the dildo nose, engine cover whale tail, the coat hanger, the shark fin, narrow track and grooved tyres, the list goes on...
We'll doubtless get used to it.

Interesting suggestion on twtter - personalise each halo livery ? https://twitter.com/seanbulldesign/status/89088258...
