Vettel: There is not that much difference with the tyres 19 July, 2013 Infiniti Red Bull Racing’s final day at the Silverstone Young Driver Test again saw the team split its running, with GP3 and Renault 3.5 Series driver Carlos Sainz Jr at the wheel in the morning and F1 championship leader Sebastian Vettel on tyre-testing duty in the afternoon. Vettel got his first taste of the new compound Pirelli tyres and afterwards said the new rubber had performed well. “We had three days of testing with a lot of different drivers in a lot of different cars and no failures – in conditions that were hotter than the [British] grand prix – so that’s good,” he said. “Obviously, we were very limited on what we could do, but for me there is not that much difference with the tyres. It was good to get in some laps though, good to get a feeling for them and it’s always nice to drive at Silverstone.” Race Engineering Co-ordinator Andy Damerum added: “We were again locked into Pirelli’s programme and you can’t make any adjustments to the car, so while it wasn’t the best balance for Seb, he’s an expert at driving round these issues and we got a lot done, 79 laps; over 460km. It’s been a useful test and aside from some small problems, which you always get with a test car, we’ve had good reliability and good performance.” (Red Bull) Subbed by AJN.
