When Renault introduced an updated power unit for the Monaco Grand Prix, the improvements reduced lap times by approximately half a second. Combined with team's already-strong chassis, the new power unit also allowed Red Bull to finish second. But despite improvements, Red Bull boss Christian Horner still thinks his team is down on power.
that Horner believes the Renault power units (branded as Tag-Heuer on the Red Bull cars) are still approximately 46 horsepower (35 kW) away from where they need to be. But he also believes Renault will be able to reduce that deficit.
Renault have made some great steps and that there are more in the pipeline. There's definitely more to come and it's about how they work in harmony with the chassis. We know that we're 35 kW behind - that's what the Renault guys tell us. We know the plans they have in place to close that gap down.
Unfortunately, the next major update won't come until the beginning of the 2017 F1 season. In the meantime, Horner believes there are smaller tweaks the team can still make to improve performance.
"We have some fuel and tuning and drivability that there's definitely performance to come from. So we're quite confident that there will still be some steps of performance by tidying up what we actually have," he told Racer.
And those tweaks could soon end up being incredibly important. Ricciardo's third-place and Verstappen's fifth-place finishes in Hungary brought Red Bull within a point of Ferrari, which is currently ranked second overall. And Horner plans to pull ahead before the summer break.
"Our target is to try and go into the summer break ahead of Ferrari," he said.
We'll see how effective Red Bull can be at this weekend's German Grand Prix.
