Red Bull team boss Christian Horner says Renault won’t spend any tokens on power unit upgrades until the Russian Grand Prix which takes place in October.
This means Daniel Ricciardo and Daniil Kvyat must attempt to get through the next five races with their current power units without further penalties.
Renault has yet to use any of its allocation of 12 engine upgrade tokens.
“I don’t think anything is scheduled now before Sochi,” said Horner in the FIA Press Conference.
“That is probably going to be the earliest we will see any form of development or use of tokens.
“So the engines we have at the moment are what we have to live with for the time being.
“Engines four and five are what the drivers have been using between Friday and Sunday racing.
“Unfortunately, Ricciardo has lost engine four, so he has only got engine five which came into service for the first time in Austria to get him through the next few races.
“Only time will tell if we can get to Sochi without incurring another penalty before introducing a new upgraded unit.”
Ricciardo and Kvyat both took 10-place grid penalties at the Austrian Grand Prix after being forced to use a fifth power unit.
Horner admitted he is unsure whether either Red Bull drivers will be forced to use a sixth power unit before the Russian Grand Prix.
“Only time will tell if we can get to Sochi without incurring another penalty before introducing a new upgraded unit.”
Red Bull enjoyed a strong Friday at Budapest, setting the third and fourth fastest times of second practice.
