Being Brazil, the threat of rain again this weekend is still a real possibility. Then the night before the race, after deciding the concrete Samba straight was too slick, it was diamond ground. This caused a buildup of dust which formed a cloud as the field rolled through for the start of the race. The low visibility was a factor in a number of accidents, especially early in the race.
Vital statistics on the track: It is a temporary street circuit which has seen heavy public traffic since it was paved with its race surface. It is just over 2.5 miles long, and features 11 corners. Surface is asphalt, the same blend as Interlagos, except for the Sambadrome straight, which is ground concrete. The race will be about 190 miles around the course. The track record is 1:27.74 (Franchitti) and last year's winner was Will Power, driving for Verizon/Penske.
