The organisers of the Abu Dhabi Grand Prix plan to make wider the entrance to the main fork of the circuit, but the most important on the Yas Marina circuit change is perhaps the inclusion of a peraltada curve, which we can see already in the Grand Prize of this year.
In fact, this is not a new curve, but by what he says, alter the cant of an already existing curve. This lets us see that it won't be a curve peraltada Indianapolis-style, but it is probably something similar to what exists today in day at the Shanghai circuit.
These changes are supposed to facilitate overtaking, although to be honest, and having seen the current circuits, the problem is probably in the car. In any case, from Autosport, they give us three points which appear to be those who will be changed.
These points are the curved 5 and 6, leading to the entrance of the fork (curve 7). These points will be expanded so that there is more than one drawn and facilitate overtaking. The curve 9, which is a bit contraperaltada, will be changed to make it otherwise, and thus also give more drawn.
It is assumed that it may be the curve by abroad, trying to pass through the area. Finally, two curves to the left of the final sector, which are quite slow, will be changed to make them faster, and keep the "rhythm" of the circuit. It's the curved 13 and 14.
The pilots have welcomed these changes, since that implies that they are willing to change the circuit if necessary from Abu Dhabi. But we must also say that there have the money to do so, which, in other places, is not the case.
