The bunched implied probabilities around 44-45% across more than 20 drivers underscore the inherent uncertainty of Practice 3 fastest-lap outcomes on Baku’s street circuit, where long straights, heavy braking zones, and variable wind reward precise setup tweaks and clean laps more than outright race pace. New 2026 power-unit rules and the absence of DRS have produced closer overall field form, with Mercedes leading the championship via Kimi Antonelli while McLaren, Ferrari, and Red Bull remain competitive after the recent Dutch and Hungarian rounds. Track evolution between Thursday’s FP1/FP2 and Friday’s FP3 session often shifts the order, and teams frequently prioritize long runs or tire data over outright single-lap speed, keeping the session result wide open until the final minutes.
