Built in 1940, the circuit has been modified throughout the course of the years, most recently in 1990.<br /><br />The cars drive counterclockwise and the straights are fairly short: As a consequence, there is only one occasion when braking is used to drop the speed by more than 200 km/h (124 mph). <br /><br />The track is very drivable with frequent changes in direction, but it also has high-speed turns that don't require use of the brakes. Every lap, the brakes are used barely seven times, but it is not the negative record for the World Championship: in Hockenheim are used five times, in Monza and Montreal six.<br /><br />Overall, during one lap at Interlagos, the brakes are used for almost 12 seconds which comes to 19% of the duration of the race.<br /><br />The presence of few hard braking points results in the average peak deceleration per lap of 3.6 G.<br /><br />Even the energy dissipated in braking by each single-seater during the entire GP is contained: 206 kWh.<br /><br />From the starting line to the checkered flag, each driver exerts a total load of 40 tons and a half on the brake pedal, which is almost identical to the Russian GP.
