What we amateurs call mechanical grip doesn't even exist anymore. Without aero, there is no grip.

Not true at all. Let them use much wider tires and allow Pirelli (Michelin, Dunlop or Bridgestone) build a high grip low deg tire to run 100km in race conditions and you would be amazed how limpet-like F1 cars would be even with limited aero.
Consider streetcars in low-speed turns can pull 1.2g when they are twice as heavy, have more weight transfer, tire compounds to last 20K and narrow tires it is clear there is a lot of mechanical grip if the formula just allowed it.
I am not suggesting cars with no downforce at speed but just ones without enough to cause so much turbulence that cars 2-4 lengths back don't washout almost completely.

I think you misunderstood. I'm talking about how cars are nowadays, not how they could be.
Teams these days set the springs, dampers and roll bars as stiff as they can get away with because if the car rolls or pitches too much it spoils the aero. So they're not really worried about how compliant it is anymore because the aero is going to keep the car pushed down onto the track.

I did misunderstand. I thought you were responding to my proffer for better/closer racing.
As far as relying more on mechanical grip the aerodynamicists hate it for obvious reasons, the big teams hate it because they have an advantage in the wind tunnel and drivers generally dislike it because of the grip and balance changing more from lap to lap.
Note I am not suggesting we go back to pre-Lotus 49B days but add an amount of ground effects "suction" and mechanical grip. The big problem of relying too much on ground effects is that it doesn't take much change in ride height by scraping the floor or lifting the skirt in a corner to result in an immediate large loss of downforce which can send a car pirouetting.

Will make kerb riding more of a challenge.

The new cars won't have skirts. There will be vanes in the venturi tunnels that keep the airflow from escaping to the sides. These vanes are attached to the axles instead of the body so they will always be at the same height off the ground.
This video explains it better than I can.

Thanks for the link, I actually saw it in my youtube feed this morning and was planning to watch it tonight.
It is really a genius idea to connect them with the rear brake ducts though I can't see how it will produce near the downforce of the skirted version but they are a lot smarter than I am.
On a related note, anyone interested in racing should subscribe to the Autosport youtube channel it has some great timely info just like they published this one right after I mentioned ground effects here.

I'm not sure either. Maybe they're willing to sacrifice some downforce for safety.

Will the new cars be using 18” rims? I have seen renderings with big wheels.
Posted on 8/1/19 at 10:32 pm to weagle99
Yes. They tested some this week I believe.

I hate the idea of big wheels and wheel covers. Though it will be interesting to watch the teams come to terms with tire changes, the first time around wheel covers caused some consternation. Plus, they do add an element to getting brake cooling correct.

I believe F1 is getting rid of the tire blankets as well. Drivers will get used to it, but adds a little more variability and demands more driver skill (on the out lap with cold tires) so I’m for it
IndyCar announced next engine specs (starting 2022) will have a hybrid component. Will be used to deliver an additional 50-60hp, and complement the push to pass system. Next engine spec is supposed to be in the 900 hp range max for road courses, currently at 750hp (both of those are with push to pass engaged)

Correct and I'm all for it as well.

Not sure how I feel about that. Is the current engine spec turbocharged? I can't remember. I was watching a race the other day and they sure sounded like they had that turbo "whistle" but I thought they were NA.
Posted on 8/2/19 at 3:39 pm to MountainTiger
IndyCar currently has a 2.2L turbocharged V6
Next engine will be 2.4L turbo charged V6, with a spec KERS system (similar to what IMSA is adding for DPi if you are familiar with that)
I think IndyCar realized they couldn’t attract another engine manufacturer without hybrid technology as part of the formula. All about marketing. Hopefully this brings Porsche back to the table. Would be great to get a Ford backed Cosworth engine into Indy as well.
Edit: fixed engine displacement figures, currently at 2.2 and going to 2.4L

McLaren has been rumored to fielding a car in Indy possibly in the next year or two with Honda. However, the relationship between the two are pretty rocky right now and the chances of that is pretty slim.

Interesting that they're going with a bigger engine. Most racing series are going smaller and smaller. DTM this year went from a 4.0L V8 to a 2.0L inline 4 with dual turbos. The cars are actually faster with the new engines.
Correction: They're single turbos not dual.

McClaren will need to have a Chevy (Ilmor) engine unless Zak Brown is ready to grovel in Tokyo
...
Think the slightly larger engine in 2022 was a way to increase hp without significant R&D spend from Chevy and Honda. Interestingly Jay Frye, IndyCar CEO said they wanted to break the 250mph mark at Indy. I’m skeptical that happens because of safety reasons.

What's the consensus on this weekend? Hamilton with the redemption after Germany?
