Oscar Piastri says McLaren’s pace deficit to Mercedes and Ferrari stems from a narrow operating window and surface sensitivity after a muted Sepang showing that ramps up pressure.

McLaren trails Mercedes by 240 points in the constructors, sharpening the need for a response before the team heads to the Singapore Grand Prix, where conditions differ markedly.

Piastri highlights Malaysia’s abrasive asphalt as a key disruptor, compromising ride control and aero platform on the MCL40 despite 2026 rules flattening floors to reduce ride-height sensitivity.

He maintains the surface is not the sole cause; a blend of setup choices, tyre behavior, and conditions explains the shortfall.

The MCL40 still shows flashes. Piastri’s hard-tyre stint runs among the fastest, while Lando Norris records strong speed on softer rubber at stages.

Those peaks underline a tight setup window. When engineers hit it, the car looks quick; when they miss, balance and tyre management suffer.

Consistency remains the deficit. Recent weekends expose difficulty adapting across compounds and evolving track states, a hallmark of a sensitive platform in the current development arms race.

McLaren expects the smoother streets of Singapore to reduce surface variables, offering a cleaner baseline to chase mechanical grip and aero stability.

Piastri expects a clearer read on setup direction and aims to convert underlying pace into points as McLaren seeks to reset momentum and close ground.
