Having lost most of the morning while the team worked on fixing some minor hydraulic leaks that had been discovered during a configuration change, Ferrari found itself further confined to the garage in the afternoon when its garage systems went down.

Vettel was able to get going again before the end of the day – ending up second quickest overall – but was left slightly annoyed at the missed opportunity to get through all he had wanted.

"It was a bit mixed, not ideal," said Vettel about his day. "We lost a lot of time, as we had an issue with the car that we could fix. And then also we had a power supply issue.

"The whole garage shut down, I think we lost another two hours trying to fix it before it came back."

Vettel said that in the end Ferrari's two days of running had not been too bad though, with third driver Antonio Giovinazzi getting through a good programme on the opening day.

"When we got on track we were able to at least try a couple of things," added Vettel. "Yesterday was good for Antonio, he got most of the programme done and we could reconfirm a couple of things. Ideally we would have liked to run more today but it was still good to get some laps."

Vettel said that he had not paid too much attention to what Mercedes had been up to, as the German car manufacturer ran through an extensive tyre programme to better understand its long-run form.

Asked about his rivals, Vettel said: "I don't know what they did. They obviously ran the whole day and didn't get to follow much in the afternoon when we started running.

"Before that I followed a bit, but you don't know what people are doing, so it doesn't really matter where you are on the timesheets.

"But I was reasonably happy with the car. We had a good balance at the weekend and we were able to carry that over for the test."
