At Interlagos, variable weather, high altitude, and the circuit's mix of high-speed sweeps and tight infield corners create shifting grip levels that reward setup experimentation during FP3. Recent sessions show Mercedes, Red Bull, McLaren, and Ferrari separated by small margins on single-lap pace, with midfield runners like Williams, Alpine, and Sauber also posting competitive times when track conditions evolve. Teams often split programs between qualifying simulations and long runs, while tire warm-up and wind gusts add further variability. These factors sustain broad parity across the grid, reflected in the tightly grouped market prices for the fastest FP3 lap.
