The tightly bunched probabilities around 49.5% for frontrunners like Norris, Verstappen, Piastri, Leclerc, Antonelli, Russell, Gasly, and Bortoleto reflect Baku City Circuit's unpredictable nature ahead of FP3 on September 25. The 6.003 km street layout mixes high-speed straights with tight corners, making sessions highly sensitive to wind, traffic, tire compounds, and clean laps during qualifying simulations. Mercedes leads the standings with Antonelli on 292 points, but recent form across McLaren, Ferrari, and Red Bull shows multiple cars capable of sector-leading pace. FP3 typically serves as a final setup window rather than a pure performance benchmark, amplifying uncertainty and keeping implied probabilities clustered among a broad group of drivers.
