Interlagos (Brazil)
The Senna S at Interlagos, officially Turns 1 and 2, is one of the most iconic and technically challenging corner sequences in Formula 1. Named after Brazilian legend Ayrton Senna, this complex begins the lap at the Autódromo José Carlos Pace and plays a key role in both qualifying and race strategy.
Drivers approach the Senna S at high speed down the main straight before braking hard into Turn 1, a sharp left-hand corner that quickly transitions into Turn 2, a right-hand curve with a tricky downhill exit. The corner demands precision, as drivers must brake late while steering into the turn—making the car highly unstable and prone to lockups or oversteer. The immediate change in direction requires excellent balance and throttle control.
- Turn Type: Downhill chicane
- Challenge: Heavy braking from high speed, immediate change of direction; key overtaking point.
The exit of Turn 2 is just as crucial, as it leads onto the Reta Oposta straight—any mistake compromises acceleration and opens the door to overtaking. In wet or mixed conditions, the downhill camber adds an extra layer of difficulty, increasing the risk of losing grip. The Senna S is also a prime overtaking zone, but with limited space and aggressive braking, it often leads to wheel-to-wheel battles or contact. It’s a corner that punishes hesitation and rewards bravery.
