Sebastian Vettel: "The 4.3km circuit will this year stage the World Championship final. That will be exciting because at Interlagos you have a combination of passionate fans, driving anti-clockwise, bad bumps and extreme altitude. The thin air makes it tough for the engine, because São Paulo is located 1000m above sea level, so it costs us about 40hp. The long left turns put an extreme burden on our neck muscles, because of the centrifugal forces that are created from driving anti-clockwise. So I'm doing special workouts for São Paulo, to build up my neck muscles and get them used to it."
Mark Webber: "Brazil is a great way to finish the year. It's one of my most favourite weekends because of the history with the drivers they've had; Senna, Piquet and Fittipaldi, these guys did a huge amount for the sport. Interlagos is a legendary circuit, it's got a great atmosphere, there's always been a bit of drama and also there is always a bit of weather floating around. It's a Grand Prix that I have done well at in the past. It would be good to have a smooth weekend with no issues, a clean start and the car running smoothly for the whole weekend, then I'm sure we can finish the season very strongly."
