Day one of the 2026 Monaco Grand Prix revealed fresh technical challenges as the FIA banned active aerodynamics, prompting teams to experiment with rear‑wing winglets and exposing reliability worries for Aston Martin.
Fernando Alonso warned that a "random downshift" issue that plagued Miami could be disastrous in Monaco, and teammate Lance Stroll said the car loses gear sync below 40 km/h – a serious problem on the Loews Hairpin. Ferrari's Charles Leclerc said his new contract was driven by loyalty to the team and confidence in principal Fred Vasseur, while hinting at undisclosed clauses. Valtteri Bottas dismissed circulating rumours about his future with Cadillac as "complete bulls**t", noting the team backs him.
Mercedes, McLaren and Red Bull unveiled inventive winglet concepts to replace the banned active aero, though gains are expected to be marginal. Lewis Hamilton praised his new Ferrari race engineer, calling him his "Italian Bono". Alpine is probing Pierre Gasly's recent balance woes, and Carlos Sainz voiced frustration with Williams' performance dip.
With the grid set to form later in the weekend, the effectiveness of the winglet tweaks and the resolution of Aston Martin's gearbox issues will be key indicators of which teams can capitalize on Monaco's demanding circuit.
