Since it is now official that next year's Mexican Grand Prix of F1 will be held at Mexico City
http://www.autosport.com/news/report.php/id/115106 it should come as no surprise that, on this track-minded discussion board, the question would come up on how to actually modify the Hermanos Rodriguez circuit for the needs of current F1.
Is F1 going to use the rectangular baseball stadium loop as ChampCar did, or will F1 be daring and use the full Peraltada as A1GP did? How will the runoff need to be altered? Is it even possible to increase runoff and safety on the outside of Peraltada since there is a highway behind?
Apart from that, I feel the current track layout should best be left largely unchanged to keep the circuit as original as possible. This is a track with a long heritage after all. Turn 1 should make for a wonderful overtaking opportunity even with today's F1 cars and the other significant overtaking opportunity should be at the end of the back straight, no matter what type of corner there is going to be in the end.
But most importantly, a best case scenario for an update must please keep that undulating left-right-left-right-etc. combination of corners which leads out onto the back straight. It surely is going to get new kerbs, though, but the architect will have to tame himself from putting too much tarmac runoff in place, otherwise it would be an invitation to short-cutting. (A similar case would be the final corner of Dijon-Prenois where they have since broken up the tarmac runoff and brought back a small area of grass to keep drivers from shortcutting).
So how would your best and your worst (Tilkefied) updates to Hermanos Rodriguez look like?
Thank you in advance for your contributions.
