F1 Data Analysis: Vettel vs Verstappen — SQL & Power BI A SQL + Power BI comparison of Sebastian Vettel's (2010–2013) and Max Verstappen's (2021–2024) four-title runs at Red Bull Racing — same team, different eras, very different paths to the top. Built on the Ergast F1 database: 14 SQL queries across 5 categories (dominance, race execution, consistency, teammate benchmarking), visualized in a 5-page Power BI dashboard. Key finding: Vettel converted a higher share of available points on average (69.05% vs Verstappen's 63.28%), despite winning fewer races overall.
