Angry Vettel slams Mercedes tyre tests
Sebastian Vettel has pulled no punches in claiming that Mercedes gained an advantage from their private tyre test with Pirelli after the Spanish Grand Prix.
"It's a critical issue," he said. "Each test kilometre is an advantage, and Mercedes had the chance to test tyres that we will probably race at Silverstone.
"It's a bit weird if the regulations don't allow you to test and one team goes testing," he told Süddeutsche Zeitung. "There's talk of an agreement and blah, blah, blah, but it's not good. What's the solution now? Does everyone have a go for three days or are they the only ones? It's just silly to come up with these discussions now.
"We all know how important testing is in the winter, but then the quality of testing is not the same because the conditions are different and the cars are very early in their development. So if you get a chance to have three days of testing in the middle of the season then it's a big help."
He added: "It's now going its formal way in front of the World Council [Sic. International Tribunal] but surely it's not right to go testing in the season. It's forbidden and that's why the whole argument started."
Mercedes and Pirelli could face hefty penalties when the case is ruled on by the FIA's International Tribunal.
