McLaren: the F-duct system effective in Sepang

McLaren Mercedes' F-duct system provides an excellent advantage on Sepagn's long straights. Lewis Hamilton was the fastest in both free practice sessions on Friday, enjoying a significant advantage provided by the Woking team's system, which allows it to improve top speed.

"It's a high-load circuit and I have no doubt that Red Bull and Ferrari have more load than us" declared the Englishman.

Part of the McLaren advantage is the low downforce and the impressive Mercedes engine, but also the functioning of the F-duct system: Hamilton and Button can in fact block an opening on the body by pressing a button with their knee and stall the car. rear wing.

"Our top speed is really good" admitted Button. "We are 14 km/h faster than the Red Bulls, 14!" he exclaimed enthusiastically.

Ferrari didn't seem very competitive while Red Bull doesn't seem to be able to repeat Australia's performance.

"We are not at the same level as the last two races," Vettel told El Pais newspaper. "We need something more to be on pole."

"In the second sector we are the best but in the first and third sectors with the long straights we lack top speed" declared Helmut Marco, Red Bull advisor. "We want to win the championship, so we can't say our car is good here or not good there. We have to have a competitive car everywhere."
