I don't know man. This again reminds me of 2014. Mercedes going full power while Ferrari going for the compact engine to favor aerodynamics. And we know what was the results. Mercedes did it in 2021 too. Those bulgy plenums don't do good for aerodynamics but gave 20 more hp to Mercedes.
A point that I think is exaggerated is 8% or about 80hp loss due to the introduction of E10 fuel. Ethanol has 30% less specific energy than gasoline. With a very simple calculation, you could see that the fuel mixture is losing about 3% of energy compared to last year. Now, why does losing 3% of energy reduces power by 8% (80hp)? In road cars, if you switch from gasoline to E10, your consumption increases by 3 to 5 percent (Or in other words, if you use the same amount of fuel, you lose about 3 to 5 percent of power). So why a formula 1 car should lose 8%? I think it's exaggerated by journalists.
