Red Ferrari, say, Frenchman reversed into me (9)

'red ferrari' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'frenchman reversed into me' is the wordplay.
'frenchman' becomes 'rene' (common French name).
'reversed' is a reversal indicator.
'into' is an insertion indicator.
'me' becomes 'carme' (I am not sure about this - if you are sure you should believe this answer much more).
'rene' reversed gives 'ener'.
'ener' going into 'carme' is 'CARMENERE'.

'say' is the link.

Can you help me to learn more?
