The 71 lap Brazilian Grand Prix will be a true test of durability, heightened by the fact that the race is run in an anti-clockwise direction. The 4.3km circuit consists of 13 medium and slow speed corners, nine left and four right, and has a blend of long, fast straights and gradient changes. With such a varied layout, set-up compromises are inevitable, and the challenge lies in achieving optimal aerodynamic efficiency around the lap. Interlagos is a notoriously bumpy circuit, so not only is it draining on the drivers, but the cars must have a good mechanical balance for driveability. Combined with the bumps, the track is also particularly abrasive, so harder compound tyres must be selected to ensure their survival. Engines are also under intense pressure in Brazil, with the long straights demanding extensive periods at full throttle and high revs, while the high altitude and thinning air saps approximately 8% of overall power around the lap. Plenty of overtaking opportunities, combined with the area’s unpredictable weather conditions, will only enhance what is always an entertaining spectacle in Brazil.
