Red Bull has abandoned the F-duct innovation for the rest of the Turkish GP weekend.<\/p>\n
Sebastian Vettel’s RB6 was fitted with the McLaren-style rear downforce stalling solution on Friday in Turkey, but although promising he also reported that it had not worked “100 per cent”.<\/p>\n
According to Germany’s Auto Motor und Sport, the team has decided not to use its hand-activated system for qualifying and the race.<\/p>\n
“There are undesirable side effects,” confirmed Red Bull advisor Helmut Marko.<\/p>\n
“We are going to check the data and try again in Montreal,” he added.<\/p>\n
Meanwhile, it emerges that after Ferrari used a hand-activated system in Spain, it is believed the developed version in Turkey is controlled by the drivers’ left foot.<\/p>\n
“We have solved the problems of Barcelona,” said Fernando Alonso, referring to the fact that downforce was also leaking in the corners.<\/p>\n
“Our system is not yet perfect.\u00a0 We need to keep working on it.”<\/p>\n
It had been reported that Force India’s hand-activated F-duct test on Friday had been a success, but Adrian Sutil said the team still has “a lot to learn” about the concept.<\/p>\n
