Carlos Sainz Jr.'s drive at the 2025 São Paulo Grand Prix saw him complete all 71 laps of the Autódromo José Carlos Pace, ultimately securing a 13th-place finish for Williams Grand Prix Engineering. Starting from 15th on the grid, Sainz managed to advance two positions over the course of the race, crossing the finish line with a recorded time of 1:32:57.016. This result, while a gain in track position from his starting grid slot, did not translate into championship points for the Spanish driver. The Williams team's performance spectrum at Interlagos was notably varied; Sainz's teammate, Alexander Albon, showcased the FW47's outright speed by setting the fastest lap of the entire race on lap 59, clocking an impressive 1:12.400. In contrast, Sainz's quickest lap, a 1:13.683 recorded on lap 19, placed him 14th in the fastest lap standings. This internal comparison highlights the nuanced challenge of optimizing car setup and driver performance across a demanding circuit like Interlagos, a common theme in the competitive landscape of [Formula 1 — official site](https://www.formula1.com/en).
The race itself unfolded with several incidents that influenced the overall field. Early retirements, including Charles Leclerc due to a collision on lap 5 and Lewis Hamilton with collision damage on lap 37, naturally reshaped the mid-pack battles. Sainz navigated these dynamics to maintain his position, finishing just behind Haas's [Esteban Ocon at the 2022 Azerbaijan Grand Prix](/results/2022-baku-esteban-ocon), who secured 12th, and ahead of Aston Martin's [Fernando Alonso at the 2022 Azerbaijan Grand Prix](/results/2022-baku-fernando-alonso), who finished 14th. The fight for the final points-paying positions was intense, with Alpine's [Pierre Gasly at the 2022 Azerbaijan Grand Prix](/results/2022-baku-pierre-gasly) claiming the last point in 10th. While Sainz's race was solid in terms of reliability and position management, the pace required to break into the top ten remained elusive for the Williams entry. Understanding the intricate technical regulations that govern car performance and strategy is crucial for teams, as detailed by the [FIA — F1 World Championship](https://www.fia.com/events/fia-formula-one-world-championship). The data from this round, along with comprehensive historical race results available through resources like [Jolpica/Ergast — 2026 season data](https://api.jolpi.ca/ergast/f1/2026.json), will be vital for Williams in their ongoing development efforts.
