Isack Hadjar has called on Red Bull to redesign the clutch on its car, after a poor getaway from third on the grid wrecked his United States Grand Prix.
The Frenchman had recovered from what he called a “disaster” of a weekend to qualify on the second row at the Circuit of the Americas, just 0.036 seconds behind team-mate Max Verstappen. But he dropped to fifth on the opening lap, as Charles Leclerc and Lewis Hamilton both got their Ferraris past him, and he eventually finished a disappointing sixth.
