Lack of passing 'an obvious flaw' in current F1 cars - Hamilton

Hamilton started from the pit lane and finished fourth in Brazil, making 10 passing moves along the way.

However, he admitted that it would have been harder to repeat his charge at other venues, because the laptime advantage required to overtake cars ahead would have been greater than it is at Interlagos.

"When I was in GP2 that was good fun. It was easier in GP2 to overtake," Hamilton said. "The way their floors are it was easier to be close. So to come back through the field [was easier].

"This actually is a race track where it is difficult to get past here, but the delta is slightly smaller than it is in other places.

"But if you look at most of the circuits we go to, the delta to be able to overtake the car in front is usually a second and a half, or something like that.

"You've got to be a second and a half faster, that's a whole tyre compound and a bit.

"So that just shows there's obviously a flaw in the cars' design, and whilst the cars are fantastic this year, that's an area we can improve on for the future."

Asked if his Brazil charge suggested that reverse grids would make F1 more entertaining, he said: "Reversing the grid, I mean, you didn't see the top four move around, did you?

"So reversing the grid, you'll just reverse that role, and it'll be the same."
