Red Bull F1 team boss Christian Horner says that Renault power-unit to close 47 horsepower deficit to dominant Mercedes F1.
Renault made huge steps forward over the winter and with an update at the Monaco Grand Prix, but Horner says the overall power deficit is still estimated to be as much as 35 kilowatts (roughly 47bhp).
“I think we know that we are 35 kilowatts (around 47HP) behind, that’s what the Renault guys tell us, and we know the plans they have in place to close that gap down,” he told ESPN.
The French manufacturer revealed that, in Hungary that it would not introduce any more Monaco-sized updates this year, but Horner says there is plenty more performance to be extracted from the current power-unit.
“We have some fuel, and some tuning and driveability, that there is definite performance to come from,” he said.
“So we are confident there will be some steps of performance by tidying up what we actually have.”
