I think ride control as hamilton says is maybe what's at play along sith ride height.
Since 2022 redbull seem to have very fine control of their floor as it approaches the lower regions of compression.
In fact i hate to say it but i did enjoy watching the Redbull go through the esses at COTA each lap. It's a very mesmerizing car to watch. Super smooth.
Mexico would give a good idea of how real Mercedes performance was at COTA. But i am hoping that next year they improve the suspension. They have admitted openly that rheir ride is not the best.
