WIP What should I name my BeamNG mod?

Hi all, Im making a lore-friendly BMW 4-Series but I dont know what to call it. Can anyone give ideas?
Mod it not mine, I asked for permission and only will be released if such permission is accepted.

Also the generation is F32 and has no M4 configuration.

 

ETK M-Series ?

ETK P-Series ?

 

ETK Y-Series
ETK C-Series

 

C-series is already taken
--- Post updated ---
@BaconBeam Yk you could make it the 2020 - 2023 ETK S-Series

 

ETK J-Series or 700-Series

 

ETK ඞ-Series

 

Oh that should be the name !
