Helmut Marko’s ‘papaya rules’ dig after new McLaren strategy

Helmut Marko joked that McLaren’s choice to not swap positions at Suzuka was a ‘new version’ of their much-discussed ‘papaya rules’, their phrasing of how the drivers race each other.

“The strategy they choose is up to them,” he reportedly told the German media.

“It looked like Piastri was the faster driver. The question is whether he could have overtaken Max, because that’s a different story on this circuit.

“But maybe this is a new version of the Papaya Rules,” he added with a laugh.

“We would have swapped,” he continued. “But McLaren has the Papaya Rules, and they are their own rules.”

Horner gives Tsunoda-Lawson verdict after Red Bull swap

Christian Horner gave his review of both Yuki Tsunoda and Liam Lawson, after the two drivers swapped seats within the Red Bull stable in Japan.

“I think Yuki, he settled into the team, he’s given very good feedback,” said Horner.

“I think unfortunately for him, his FP1 was very strong, FP3 was fine, Q1, he was only a 10th away from Max. Q2, he made a mistake. He was 15km quicker than he’s ever been into Turn 1, had a moment, and then you’re chasing the lap the rest of the way.

“And so qualifying 14th dictated his race.

On Lawson, he added: “We’ve spoken throughout the weekend. Saw him on the grid, saw him last night at the barbecue.

“He just needs a bit of time and he will find his feet.”
