Formula 1 looks poised to announce its new engine regulations for 2021.
It is expected that the FIA and Liberty Media will simplify the rules and attract new manufacturers like Porsche by, among other things, dropping the MGU-H unit.
'A clear indication'
"It's a very complicated process with lots of meetings and the manufacturers discussing every detail.
But I think we will very soon have a clear idea of what the 2021 engines will look like," FIA race director Charlie Whiting told Auto Hebdo.
The French report said the regulations might even be known before the end of June - in the next few days.
The uncertainty about the engines and other aspects of the 2021 regulations is why drivers like Daniel Ricciardo and Lewis Hamilton are looking to sign only two year contracts.
"No reasonable driver will sign for longer than the end of 2020. At the moment nobody even knows what the engine regulations are," Mercedes' Hamilton said.
