McLaren missed its winter development targets and failed to score a point in the opening two rounds of the 2023 season. This came as rookie Piastri acclimatised to life in the championship.
Piastri settled and found his form while the MCL60 was heavily upgraded. He then ultimately beat Norris to winning his first F1 race - with Piastri scoring victory in the Qatar Grand Prix sprint event.
That personal progress - and the development of the team, which allowed it to occasionally challenge Red Bull for wins – could result in a more closed-off dynamic between Piastri and Norris.
But speaking exclusively to Autosport, Piastri says the pair must stay “completely open” with one another by sharing data if they are to help drive the entire McLaren team forward.
“The relationship is still exactly the same,” said Piastri. “Of course, we're not winning [titles] at the moment. We're a lot closer than we were, but we still need to find that bit more to challenge and to beat Red Bull.
“So, it's still very important for us to work together and help the team develop the car.
“The team back at MTC and the engineers here are all doing their best to try and help things. But if me and Lando have got any additional info or directions on things, then anything we can do to help is going to help both of us.
