World champions McLaren, who last week said they would first run their new car on either Tuesday or Wednesday, were not ready to run until late in the morning session and decided because of the weather to wait to run until Wednesday. They will now take part in each of the final three days of the test.

For Ferrari, Charles Leclerc drove in the morning and Lewis Hamilton in the afternoon, doing a total of 123 laps – just short of two grand prix distances – between them.

Leclerc said: “It’s not been the best conditions because it was a bit rainy, but we did our programme because we are not focusing on performance.”

F1 has introduced revised rules for chassis, engines, tyres and fuel this season that means the cars are completely new, and a much bigger role for the hybrid part of the engine will make energy management a major factor in F1 this season.

But Leclerc said it was “very early” to comment on the car’s behaviour.

“We haven’t pushed any bit of the car just yet, it was all about doing a proper system check on track,” he said. “We will know a bit more the more we do mileage. The first feeling is it is going to be a bit more of a challenge for us drivers to manage those things and then let’s see if it’s going to make things more exciting.

“For now, we have gone through the very first preliminary checks of the car, everything went properly and we will go through our check list of the first systems to then eventually what matters most, which is performance. But this will come probably a bit later in these three days and then trying to understand first how everything behaves.”

Ferrari had a poor season in 2025, with both Leclerc and Lewis Hamilton failing to win a grand prix, and have hopes the new rules will enable them to be more competitive.

Leclerc said: “I am very excited to see what the others have in store and when we start pushing a bit more to see where we are compared to the others.

“This year is a big opportunity for every team to do something different and maybe gain bigger advantage. I hope we are the team that will manage to make the difference, but wherever we start we will push at the maximum to try and bring Ferrari back to the top.”
