Ferrari Power Unit Hardware & Software

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

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.

I dont think it's about going compact, it's about going lighter (weight rather than size). Also honda produced a stellar engine in 2021 and they went below their 'size zero' concept too. So lets see what comes up.

Rumours are rumours, but most things we hear are about making the engine more powerful, optimizing combustion...
In comparison these "lightweight" rumours are very recent, and i agree with some who said with minimum weight and CG... kinda pointless.
