(GMM) F1 is heading for a V6 twin-turbo engine formula for 2021.
That is the news of Germany's Auto Motor und Sport, after car manufacturers were told to submit their proposals by the end of May.
The report said the general consensus is that after the expiry of the unpopular current 'power unit' rules, the manufacturers want the 1.6 liter V6 basis of the 2021 engines to stay.
But there will be two rather than one turbochargers, with the MGU-H dropped and replaced by KERS.
Auto Motor und Sport said the next engine meeting will take place in July, with a final decision to be taken by the end of the year.
Until then, Red Bull will reportedly continue to argue that certain parts of the 2021 powertrain should be standardized, including the KERS, battery and turbos.
But Dr Helmut Marko denies that Red Bull wants 'standard' engines.
"People have misunderstood," he said.
"We want an engine that can be produced technically and financially by an independent manufacturer, for EUR 25 million."
