3. Information augmentation Pre-race atmosphere: Kimi Formula One newcomer Kimi Räikkönen is not worried about the fact that he will be racing on a new track this weekend. "Interlagos is another new circuit for me to learn. It doesn't worry me to know that it is anti-clockwise and considered as one of the toughest of the year in the calendar," said the young Finn. "The track is difficult because it is very bumpy. It is a lot of work to find a special set up for that, unlike any other track in the F1 calendar. I'm looking forward to driving there, and to challenging again for some points," he concluded. Last year the Sauber team didn’t participate the race in Interlagos. They had to pull out of the weekend after excessive vibrations caused by the bumpy nature of the circuit. This caused many rear wing failures for the team. Sauber are confident they will have no such problems this year.

Although the track was there long before his birth, it took the success of Emerson Fittapaldi to bring Formula One to it. Set in the suburbs of San Paulo, the original track was 4.949 miles in length, one of the longest of any track used in any era. It was made up of a sweeping outer section, followed by a tight and twisty trail through the infield. The track is very bumpy, and it takes great reflexes and skill to have control of the car in any given situation, the tight corners posing some serious problems for the speeding machines. A chicane has since been placed at the first corner, to slow the cars down. Ayrton Senna drove his maiden race for Williams at this track. He had already achieved his dream of winning his home race in 1991 and again in horrendous conditions in 1993. Although he had hoped to win with Williams, it wasn’t to be, and Michael Schumacher won the first race of his championship year. Interlagos traditionally either precedes or follows Argentina on the F1 calendar, but since the Argentina race was cancelled, it has been second on the calendar. In 2000 we saw Ferrari driver, Michael Schumacher take victory with David Coulthard a close second. However, due to the roughness of the circuit, there was controversy over the wear on most of the top six finishers. In the subsequent scrutineering, officials found a technical infringement with Coulthard’s Mclaren, resulting in the disqualification of the Scot from the race.
