After being forced onto the grass to avoid hitting Sebastian Vettel, Hamilton saw Verstappen pull up alongside him into Turn 1 and the pair could not make it through Turn 2 without colliding and escaping on another verge.
Both dropped down the order, although Hamilton only fell two places and was able to make a dicey one-stop strategy work to secure a 1oth victory of 2019 and move to the brink of a sixth world title.
As the image shows below, however, he did so with not-so insignificant damage to his W10.
Describing how the missing pieces affected his race afterwards, Hamilton said: “I was not expecting to have that pace and to be able to keep up with the Ferraris but it worked and even with a damaged car.
“A big part of the side of my rear floor was missing. I didn’t actually know how much was missing or what was damaged but the balance was quite a lot different.
“The rear end was quite weak so I was particularly sliding around a lot in the high-speed, so I had to change my settings quite a lot and had to drive it a little bit differently because I couldn’t attack the same way on the entry of corners because the rear stability wasn’t the same.
“I would imagine a good couple of tenths probably, just from rear floor damage.
“It’s quite a sensitive area around where the tyres is. But why I’m probably even more happy that I was able to make these tyres last the way we did.”
