Oscar Piastri overtook Charles Leclerc to win the Azerbaijan Grand Prix as Formula 1 title challenger Lando Norris staged a stunning comeback to finish ahead of standings leader Max Verstappen.

His teammate, Valtteri Bottas, likely extracted the maximum he could out of his car with a 16th-place finish. Sauber still is the only F1 team without a point this season.

But when you look at rear-facing onboard footage from Piastri’s car, you can see something interesting: The outer portion of McLaren’s rear wing DRS flap lifts ever so slightly as Piastri negotiates the serpentine streets of Baku.
