At the end of the 2 weeks of pre-season testing sessions it’s hard to form a conclusion.
Mercedes look to have gone about it with a clear advantage in performance & preparation from the get-go & as the other teams got their acts together Mercedes look to have remained as favourites.
Red Bull & Ferrari have mad e progress with speed, handling & whatever else held them back at the start, the rest are not that far behind. All to play for.
The big news is the politics that hit the fan over the FIA investigation into the Ferrari engine. This goes back to 2019 when Ferrari were accused of engine illegality (compliance to regs)
The FIA investigated & that has just been published, the report said it (FIA) it had concluded a “thorough technical investigation” into the Ferrari engine & “the specifics of the agreement (reached) remain between the parties”.
Nothing has been published about if it was illegal of not, what was actually illegal & when (between what dates and/or races) this occurred.
The other F1 teams are up in arms & are considering what the next steps, rejecting what looks like the FIA is attempting to draw a line & close it out without making it clear if, when & how the engine was legal or not. There are other behind the scenes mutterings about letting Ferrari off the hook, Ferrari pressure politics & threats (again) & FIA eunuchs
This might have more legs to run
