Formula 1 is looking to simplify the aerodynamic profile of the cars for 2019.
Auto Motor und Sport reports that increasing complexity in the detail around the sidepods and rear wing endplates in particular is making it hard for teams to place legible sponsor logos.
It seems that the teams, the FIA and Liberty are therefore working on a new plan for 2019.
The now familiar aerodynamic 'slots' will be banned, bargeboards will be made smaller, and other ideas are being studied.
The report adds that a vote will be taken on any changes at a strategy meeting in April.
