Both Max Verstappen and Pierre Gasly have struggled to get the most out of their Honda-powered car in Bahrain, taking fourth and eighth place respectively in the race.

“I think it’s a tricky car at the moment,” said Horner. “Our operating window looks quite narrow and Max has coped with that extremely well.

"I think it’s been harder for Pierre. That will come I’m sure.”

Horner said that the Bahrain Grand Prix weekend, where Red Bull’s drivers never found themselves with a completely comfortable set-up, has highlighted where the team needs to improve – and given some indicators of what needs to be worked on at this week’s post-race test.

“It’s perfect timing,” said Horner about the test. “We need to find more performance.

"Ferrari were very strong here this weekend. Mercedes got lucky with a one-two, but Ferrari were the dominant team.

“Trying to understand where are our strengths/weaknesses to Ferrari here is quite important. Once you get into a window, particularly with these tyres, they looked a different team to two weeks ago. And vice versa with Mercedes.

"It’s just understanding what the magic password is.”

Red Bull has experimented with numerous set-up directions in the opening two races to try to figure out what is needed. And although some of the attempts have not worked out, Horner says the process has been valuable in improving the team’s understanding of the car.

“When you’re chasing issues like this and you’re moving a problem around, it usually points the finger in other areas,” he said. “We’ve got a lot of good data from this weekend and starting to understand areas we need to be focusing on.”

Horner made it clear that while Ferrari’s straightline speed points to a good power advantage over Honda, it is not his team’s engine partner that is holding it back right now.

“Ferrari look like they’ve selected another gear. It’s been enormously impressive, their straightline performance,” he said.

“We’ve got more to sort out on the chassis side. The engine’s continuing to make good progress. So, our focus is very much on trying to understand the tyre issues and get the car into a good operating window.”
