Red Bull to be 'even stronger' with F-duct

(GMM) Lewis Hamilton on Monday admitted he is worried about Red Bull's plans to introduce an F-duct this weekend in Turkey.

The downforce spoiling concept was pioneered this year by McLaren, but key rivals including Ferrari and Mercedes have steadily followed suit.

The system promises a straight-line speed boost, which is an ominous prospect for Red Bull's rivals, given the current dominance of the championship leading RB6 car.

"With this system the best team becomes even stronger," 2008 world champion Hamilton is quoted by Germany's Sport Bild.

"The RB6 has many good, detailed solutions. I have already told my engineers that we must copy them," added the Briton.
