Ferrari sidelined by garage power cut in test

Having lost most of Wednesday morning in Bahrain while working on fixing minor hydraulic leaks discovered during a configuration change, Ferrari found itself further confined to the garage in the afternoon when its systems went down.

Vettel was able to get going again before the end of the day - ending up second quickest - but was left slightly annoyed at the missed opportunity to get through everything 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 Ferrari's two days of running had not been too bad, though, with third driver Antonio Giovinazzi getting through a solid programme on Tuesday.

"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 added he had not paid too much attention to what Mercedes was doing, chiefly an extensive tyre programme to better understand its long run form.

"I don't know what they did," he said of Mercedes.

"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."
