Red Bull keeps the heat on Mercedes amid tyre-gate saga 6 June, 2013 The Pirelli-Mercedes test-gate saga is likely to be the hot topic of conversation this weekend in the Montreal paddock. The Red Bull camp, in particular, is keeping the heat on Mercedes, in light of the shock news in Monaco that the German team tested ‘in secret’ for Pirelli at Barcelona with its current race drivers and 2013 cars. World champion Sebastian Vettel told Sport Bild: “It’s funny, when the rules prohibit testing, and then a team goes testing.” He said it is obvious Mercedes have obtained an unfair advantage. “Every lap is certainly an advantage,” Vettel insisted. The boss of Formula One’s other Red Bull-owned team, Toro Rosso, Franz Tost agrees: “This is the most blatant rule violation of recent years.” Mercedes in hot water Mercedes argues that it cleared the test with the FIA, while Pirelli says its contract with the governing body allows 1000 km tests with the F1 teams. But, with the FIA now investigating, Red Bull’s Helmut Marko is resolute: “We will not let up.” Subbed by AJN.
