...the XX variant will have a front splitter like this:
Is there gonna be one, though? It's one thing to have a heavy supercar for the road. But on track, where weight is everything, all the gimmicks would get exposed.
Even if you were to remove the battery and every single electric motor from F80, there's just no way you could ever hope to get close to ~1,030 kg (ready to drive) of a purpose-built racer that is the 499P Modificata. And given that these two share a track during the XX events, I don't see how they could co-exist in this space. To "compete" with that would be a very sobering and embarrassing experience for the F80XX drivers.
Also, this track-only segment has moved on a lot in the past 10 years. There's many cool cars: Valkyrie AMR Pro, Huayra R Evo, Solus GT, T.50s, RB17, P900; and even cooler clubs: RBR, Arte in Pista. A heavy Ferrari with DCT won't cut it anymore.
I feel like FXX-K Evo is the end of the line for road-derived XX models. These cars could get away with being on the heavy side, because the screaming V12 would make you forgive everything. A heavy V6 track car simply has no redeeming qualities like that. You'd be better off driving a 488 Modificata at that point.
For me, the next step is very obvious. To differentiate new XX models from the Modificata race cars, Ferrari needs to return to V12... and make the car light. The F80 monocoque can stay, but the rest needs to be bespoke and purpose built. That's how you make people bust out their bitcoin wallets.
When they open the engine bay and show us the engine:
At least it can be opened. Unlike the one on McLaren W1.
