The ongoing campaign is 14 rounds down, and Sainz has spotted a few issues on the challenger that need to be fixed ahead of the 2026 season.In line with this, the Spaniard has pinpointed the poor aerodynamic characteristics of the FW47, and has urged the Grove-based outfit to come up with a 'change in philosophy'. Via an interaction with AS, Sainz said:"We have some poor aerodynamic characteristics in long curves, where you need to maintain the load level from entry until halfway through the corner. These things fail us, it’s been a characteristic for a long time, because we perform better in short corners and straights.""At tracks like Barcelona, Hungary or Qatar, the car suffers. A change in philosophy is needed in the design, to ensure next year’s car works well at different circuits."After the first 14 rounds of the 2025 F1 season, Sainz is currently in 16th place in the drivers' standings with only 16 points. His Williams teammate Alex Albon, on the other hand, has fared well and is currently sitting in P8 with 54 points.
