Formula 1's new sporting manager Ross Brawn is hard at work devising the rules which will hopefully guide F1 to a prosperous future.
Last week, Formula 1 stakeholders met to discuss the F1 power unit of tomorrow, meaning beyond 2020 when the current regulation platform expires.
FIA president Jean Todt revealed that the plan is to make the current 'power units' simpler, cheaper and louder for the future.
"Before we think about a sustainable car concept for F1, the engine must be clarified," insists Ross Brawn.
"Everything else depends on it."
Germany's Auto Motor und Sport has the first details.
Correspondent Michael Schmidt said the early frontrunner for the 2021 engine concept is a V6 twin-turbo producing 1200 horse power -- and missing altogether is the current 'MGU-H' technology.
The report said it is also possible that the batteries and turbochargers may be standardised, with the hybrid element of the engine to simply be KERS.
F1 driver turned pundit for German television Sky, Marc Surer, said: "We have two problems.
"First, the FIA does not want to abandon hybrid engines. But the single-turbo removes the sound.
"The single biggest problem with F1 at the moment is the sound, and this is simply not solvable with one big turbo. We need two turbos.
"But then it becomes technically difficult to get energy from the exhaust. So the FIA may need to sacrifice the MHU-H and offer the fans a better sound."
