I'm curious, aa, Why do you believe they'd need a new platform for a RWD Z2? It seems to me they could simply use the platform that will underpin the other F2x passenger cars.
This older post from SCOTT hints that we could see a three roadster lineup, with a new RWD entry squeezing in between the FWD Z2 and RWD Z4.
To allow this, those two could be renamed Z1 and Z5 respectively, making room for a Z3. It seems a little far fetched, but it makes some sense.
