First of the aero parts on Rally cars are designed to work in a certain range of speed, compared to racing cars the speed range is very low. I'd bet that the slower (or only slightly slower if that, depending if the cars don't require ballast) acceleration out of slow corners won't make a huge difference on how the aero performs. Generally we've seen that drivers don't loose a huge amount of time on most stages when they loose the MGU (see Fourmaux comments at CER about setup vs loss of extra power).

The higher aerodynamic efficiency should of course be true.
This guy knows his stuff and been studying aero for years, so I'd be careful of being critical. Interesting comments though.

Of course the slower acceleration wont affect the aero effect so much as it's at lower speeds. Its mainly on the high speed sections where the aero really works and lack of hybrid cooling vents will be affecting it much more.

I guess this is why some drivers have complained with the lack of time to properly test the cars' before Monte 2025. As well as performance changing there is also the safety aspect of trusting it at high-speed.
