Thousands of fans pack themselves into the circuit for the only South American Formula One race of the year. Although resurfaced in 2000, the track remains bumpy. This, coupled with the fact that Interlagos is one of just two circuits that runs in an anti-clockwise direction makes this race one of the toughest and physically demanding for the drivers, putting extra strain on the drivers' muscles.
The circuit is built in a very hilly area so there are some steep gradients to the track. The combination of two straights and a section of slow, technical corners in the infield, means there has to be a compromise with car set-up and downforce, which can be further affected by the very changeable tropical weather conditions.
