McLaren Knows Exactly What's Wrong With Oscar Piastri. Knowing Isn't the Same as Fixing It

Oscar Piastri finished last season just 13 points behind teammate Lando Norris. This year the gap has opened up into something closer to a chasm, and McLaren's team principal has a strangely precise explanation for why: Piastri, he says, is still "driving and thinking" a car that everyone else has learned to drive on instinct.

That's a more interesting problem than it sounds. Most driver slumps get explained away with vague talk about confidence or momentum. This one has a name and a mechanism.

What Andrea Stella is actually describing

The 2026 regulations stripped a significant amount of downforce and grip from every car on the grid, and Stella says that shift hit Piastri's natural driving style harder than most. His strengths, carrying speed through fast corners and trusting the car underneath him, depended on exactly the kind of mechanical grip these new machines don't offer anymore.

"When you drive and think, things get slowed down," Stella explained, describing a driver who has to consciously calculate corrections in real time rather than reacting on feel. He was careful to rule out any psychological explanation. "I don't think it has anything to do with any psychological kind of opportunity," he said. "This is purely technical."

Why that distinction actually matters

A confidence problem and a technical adaptation problem get solved in completely different ways. One calls for reassurance and a change of scenery. The other calls for laps, data, and a deliberate rewiring of habits built up over years of driving a very different kind of car.

McLaren is leaning on precedent here. Stella has pointed to Norris's own struggles two seasons ago as the template, arguing that Norris eventually found his footing with the current regulations through exactly this kind of grinding, technical recalibration rather than any single fix. The team is now applying the same support structure to Piastri, betting that the same process produces the same turnaround.

The part that should make this interesting to watch

Piastri's qualifying pace has flickered back at points this year, Sprint qualifying at Zandvoort saw him within half a tenth of Norris, only for his Sunday race pace to fall away once tire wear and traffic entered the equation. That gap between one-lap speed and race-day execution is exactly what you'd expect from a driver who has the raw pace but hasn't yet made the adaptation automatic.

Stella has stopped short of predicting exactly when it clicks, but he's been consistent that he expects a "very strong Oscar" once it does. Whether that happens with enough races left this season to matter, or whether it becomes an offseason project instead, is the thing worth tracking every remaining weekend.

The key variable is whether those lessons become instinct before the calendar runs out. Every race gives Piastri another chance to turn conscious corrections into something automatic, but every missed opportunity also makes the adaptation harder to ignore.

If a driver's problem really is purely technical and not mental, how much of that turnaround is actually in his control, versus down to the car itself evolving under him?
