But justify to who?

Ferrari already got their exception from the EU regulation for CO² reduction via the E-Fuel loophole, which was tailored for them and allows them to continue selling V8 and V12 ICE-based cars beyond 2036 if they only use synthetic e-fuels.

This secures their existing business model for customers who insist on ICE-based cars and are willing to pay the premium for it.

A portion of their addressable market shifts to EV-based sports cars though, they are shooting themselves into the foot by not establishing a BOLD identity in this space soon. A bland product with a "we used to be big in ICE" brand won't cut it there
