Horner says Renault are still 45 bhp behind Mercedes

Red Bull team chief Christian Horner believes that the TAG Heuer badged Renault power unit are down about 45 horsepower on the pace setting Mercedes engine

Renault unleashed a major upgrade at the Monaco Grand Prix, but their is still a gap insists Horner, “I think that Renault have made some great steps, we know that there’s more in the pipeline and I think there’s definitely more to come and it’s how it works in harmony with the chassis.”

“I think we know that we are 35 kilowatts (about 45 horsepower) behind, that’s what the Renault guys tell us, and we know the plans they have in place to close that gap down.”

Renault revealed 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 package.

“Well we have some fuel and some tuning and drivability that there is definitely performance to come from. We’re quite confident that they’ll still be some steps of performance by tidying up what we actually have.”
