That's good to know. Obviously Haas and others don't agree.
Well, benchmark is still Merc, isn't it?
I see no reason why the former F1.5 is now the benchmark. And I saw no similar vents on anyone else like on the Haas.

I’m not talking about the vents directly in front of the rear wing like in case of Haas. I mean the vents on the sidepod. As for Ferrari for example there seems to be a reason and a theory why they put the vents into the tub region of the sidepod.
Well, from from the vents on top of the sidepod the air goes directly into the region I mentioned. They structure the sidepod in a way to aim for the gap under the rear wing.
This air needs to be guided, so they need to structure the sidepod for this. This is big compromise.
Just compare the Merc without these vents at all and the Ferrari, Haas, Aston, etc...that go with vents. On the Merc the air is going to the diffusor with a very slim bodywork. All rear axle is used for aero. On the cars with the top sidepod vents the bodywork extends bulky to the upper wishbone.
But this is not core of my argument, we can argue if the concept of Merc is better (I see no argument why not) or the top sidepod vents, best in the Merc or another thread. But the core topic for this thread is the Haas and it has the rather unique outlets at the top.

Or let’s talk about Aston Martin which also has vents on the sidepod. That car has almost zero outlet around the exhaust. Why have they chosen to put vents on the sidepods instead of opening up at the back a bit?
Because they have to direct the air through the body work. If you open up, you need to open up all the way. For Aston with the flat and long sidepod they would need a crazy tubing to get the air efficiently back to the middle. In this case you better put the hot air out early...I guess it is similar for Haas. They either need a too big cover or the slits...and hot air is still better than no air on the rear wing.
