Here's some Interlagos trivia, just to lighten-up this thread a bit:
1. The area where Interlagos is located was bought in 1938 by two local businessmen but the first time an F1 took to the track was in 1973.
2. Interlagos is 4.3km long and 71 laps total 305.9 km.
3. The record time for a GP is 1h28’01″451, with an average 208,517 km/h, set in 2004.
4. The real name of the track is Autodromo José Carlos Pace, in honour of the Brazilian F1 driver who died in a plane crash after winning a race there (his only win in F1).
5. The track runs anti-clockwise (not very common).
6. The fastest race lap was set by Juan Pablo Montoya in 2004, with a time of 1’11”437.
7. The fastest qualifying lap is by Rubens Barrichelo, also in 2004, with 1’10″646.
8. Fittipaldi, Senna, Massa and José Carlos Pace were the only Brazilians to win in Interlagos. Barrichelo came very close but never won in his backyard.
9. Schumacher is the most victorious in Interlagos, with 4 wins.
10. Interlagos hosted title-deciders in 2005, 2006, 2007, 2008 and 2009 (now we add 2012 to the list).
11. Senna won there in 1991 and 1993. The 1991 win was epic (with 6 laps remaining he lost 3rd, 4th and 5th gears, when he had a 4sec lead).
Here a video of this unforgetable moment.
12. Both 2008 and 2009 champions were from Britain, both drove the car #22, both drove cars with Mercedes engines and both finished in the same position (5th).
