The FIA and commercial rights holder Liberty Media want to avoid past mistakes by taking longer to plan ideas before changing regulations.
Discussions on engine regulations have been ongoing since a proposal was revealed at the end of October. The aim is to have a final framework in place by the end of the year.
It has now emerged that a series of concepts and ideas of how the aerodynamic direction of F1 could evolve from 2021 onwards have been collated, according to Autosport.
These were presented to drivers during their regular briefing last Friday as F1 chiefs work to gather plenty of feedback at an early stage.
It is believed the illustrations presented were focused on aerodynamic concepts, described by one driver as “futuristic” and another as “space age”, rather than a complete car design.
The concepts that focused on the cockpit area of the car are believed to have featured the halo design, rather than a version of the shield or aeroscreen that have previously been considered.
