Polygon Limits in the 3d model of the cars?

Well, that's the question:
i'm working over new retro cars, and i want to know if the polygon limits in the cars is the same in the new automobilista sim.
In the future, we can use better models (with more polygons)?
When we shall have the new driver (animated)...what about the polygon quantity?

Sorry by my english, is too basic

Greetings mates !
