Reigning world champion Sebastian Vettel says the Pirelli tyres lack consistency and admits his disappointment with his Red Bull team’s final days of testing.
The Milton-Keynes based team managed 158 laps over the weekend, compared to the 248 Mercedes managed.
High degradation with Pirelli’s new 2013-spec tyres has been an issue for all the teams so far this year and Vettel, who has won the title for the last three years, said the lack of mileage has meant the team didn’t quite gather all the data they had hoped for with regards the tyres.
“We haven’t been able to tick all the boxes we would have liked to and the last two days weren’t as good as we had expected, but there is a bit of time left until the season starts,” said Vettel who finished eighth fastest on the final day of testing.
“I think we all have been limited by what the tyres can do. It was extremely difficult to read some set-up changes and find a direction with the car as the tyres were simply not good enough.”
However, Vettel said he was still positive ahead of the season-opening Australian Grand Prix.
“Testing was good for us as a whole but surely we would have loved to have had more consistency,” he said.
“Especially from a tyre point of view, I think all the teams suffered the same kind of problem, therefore it was difficult to really read the changes and the steps that we tried to make but that’s how it is.
“We need to have a good look at the data between now and Melbourne to have a better understanding of what to expect in Australia and the first few races of the season. In my opinion lap times didn’t matter all through the winter tests.”
