Brazil preview quotes: Red Bull

Mark Webber: "Brazil is one of the best tracks of the year in terms of the atmosphere. The Brazilians are fully into their motorsports and have had lot of world Champions in the past. I obviously have good memories from there from last year, it was a nice race to win and we will clearly be trying to get another victory this year. It's now coming to a pivotal stage of the Championship and we need to make the most of every opportunity we can."

Sebastian Vettel: "There are a lot of positive things about the upcoming event in Brazil. The circuit is fantastic and the spectators are passionate about racing; the atmosphere during a race is great and the city is interesting. The Interlagos track is a challenging one for the drivers because it's anti-clockwise which, after a season of racing on clockwise circuits, puts a strain on your neck muscles. Also the big bumps are demanding. The circuit requires good aero- efficiency which should suit the RB6 although the long, uphill start-finish straight will give an advantage to the more powerful engines. It's always a challenging circuit and the weather often plays a part."
