Both McLaren drivers finished on the podium at Suzuka and Losail, while Piastri also took the sprint pole, which he converted into a win at the latter venue.
However, the Australian, who learned the COTA track when he tested an Alpine early last year, believes that the bumps and slow corners won’t favour the MCL60.
"It's my second time, I've been here before, but not raced here,” he said when asked about the track. “It's a really cool circuit. A lot of different types of corners, a lot of elevation change, which is cool as well.
“But we'll see how competitive we can be. I don't think it'll be quite as good as the last couple of weekends. But hopefully we're still in the mix."
He clarified that he meant that the team wouldn’t comfortably lead the chase of Red Bull, as it did at the previous races.
"I think when I say we might not be as good as the last couple of weekends, I'm hoping that kind of means we're in the fight with Ferrari and Mercedes.
“I've seen Mercedes have got some upgrades. So we'll see what their performance is like. But I think the last couple of weekends, though Mercedes were quick in Qatar, we were probably second quickest behind Red Bull.
“And this weekend, I don't think we will be, or if we are, it’ll be a lot closer with Ferrari and Mercedes."
