Oscar Piastri says McLaren has “Mercedes envy” over cornering performance, highlighting the deficit defining the 2026 Formula 1 fight.

Mercedes wins 11 of 17 races and closes on a ninth constructors’ crown, while Kimi Antonelli leads the drivers’ standings.

McLaren, last year’s constructors’ champion, struggles to adapt to new regulations and now defends third against a resurgent Red Bull.

Raised Pirelli tyre pressures, introduced to safeguard cars if active aero fails, increase carcass stiffness and ballooning, reducing confidence on corner entry.

Piastri accepts those pressures hurt, but argues they do not fully explain the deficit to Mercedes’ W17, especially in high‑commitment turns.

He points to Mercedes’ ability to brake later and rotate cleanly, carrying speed while maintaining stability over longer stints and changing conditions.

Some of Lando Norris’s poles, Piastri suggests, come from exploiting short‑lived peaks beyond the car’s usual operating level.

The larger problem is inconsistency. McLaren peaks one session, then loses balance the next, aligning with themes in Piastri’s key F1 struggles this season.

That volatility complicates development, narrows the setup window, and exposes correlation risks between simulation tools and trackside behaviour.

Recent swings, from sharp qualifying to fading race pace, echo patterns since Singapore, discussed in Piastri’s Singapore GP reflections earlier in the campaign.

Piastri also stresses driving‑style adaptation. Extracting entry rotation without overheating fronts demands precision with brake migration, diff settings, and minimum‑speed targets.

Execution becomes critical across variable fuel, wind, and track evolution, where Mercedes appears to retain a broader, more forgiving operating range.

After the triple‑header, McLaren’s cushion over Red Bull drops to seven points. The RB22 builds momentum with back‑to‑back wins, tightening the fight for third.

That pressure extends to leadership and execution, highlighted in Brown’s warning to Norris and Piastri, and places strategy and pit‑wall agility under greater scrutiny.

To close on Mercedes, McLaren needs repeatable tyre preparation, improved corner‑entry stability, and a wider setup envelope across temperatures, compounds, and ride‑height constraints.

Converting intermittent peaks into sustainable race pace would reduce reliance on standout laps or Safety Car fortune and unlock consistent podium contention.

For now, Piastri’s candour frames McLaren’s task while Mercedes’ march continues, a context underlined in Mercedes F1 2026 champions analysis.
