Sure thing @keithcollantine
I remember this article, the suggestions came from Wéber Gábor (WTCC driver, Michelisz’s teammate last year, also the commentator of the F1 TV broadcast), and if I remember correctly @atticus-2 posted this in the forum at that time.
In the article he says:
“We have a finite number of options because of the terrain and the lack of space. I wouldnt touch the combination after the chicane, its technical and challenging, the track would lose some of its essence, moreover it would be a lot shorter. It would be possible, to expand the circuit moving inward, but it would require a lot of logging (chopping trees), it wouldnt give mutch more space, and it is not preferable from the view of environmental protection. After turn 2 it would be possible to extend the rundown to Mansell (turn 4), but there wouldnt be more overtakes, moreover it is a charasteristic, ‘traditional’ turn too, it would be a shame to lose it.
In my opinion, we should think about the part after Mansell, the left side of the track near or at the drive-in-movie. I would turn the trace sharply down with a combinaton or a short straight. From there to the right again, so I would turn upward with a straight, which either would end in a hairpin or a turn simmilar to T14 in Sepang. The point would be to guide the track down to the left and then up-right back to the original trace, in a way that allows different lines: one should be able to try an out-brake maneuver, but the car on the inside should be in a disadvantage on the – now longer – rundown to the chicane.
The other, longer versions lower-right part could be a long righthander, with a fast entry but sharper exit, or a long fast S curve, like on the new part of Silverstone, where the drivers enter with high speed but can make different lines work.
Both additions would end at the chicane, creating a plus overtaking opportunity. I think the runoff area could be extended if neccessary, but thy chicane could be moved too.”
I think his ideas are valid, but he drives touring cars, so there is a difference between his experiences and his idea of ideal overtaking spots compared to F1. He was overtaken at the chicane this year by Michelisz but he lifted to let Norbi through, and it was still narrow at a mutch lower speed, so it might be a good idea to either lose the chicane and have the drivers to drive more carefully (because the lack of runoff), or widen the chicane too.
