Multiple threads for a single car would be very confusing for those who aren't regulars, and probably even for some regulars based on what goes on in here. And I don't see why a title should make a difference, the idea has always been to purely discuss the development, whether mechanical or aerodynamic. If that point hasn't been gotten out to everyone by now there's not much we can do shy of adopting a system where the mods have to "approve" posts (which would not be adapted, so don't worry).
Remember that we also have some team specific threads already up and running for those who don't want to just discuss technical aspects (hint hint).
And don't forget the topic for car comparisons:
