Formula 1 with the United States Grand Prix has entered the cycle of races that are held in the great American continent, now it’s time for the Mexico GP, home race of the much-discussed Sergio Perez.
CHARATERISTICS OF CIRCUIT
The circuit is 4,304 meters long and will take 71 laps. is a circuit that has different types of curves, from high speed as the second sector or low speed as the last sector.
It will require a very loaded setup because of its high altitude (well 2229m above sea level) one of the most difficult races on this point of view, where not only the aerodynamic load will increase, But the Power Units will also have to push much more and this is not good news for the Alpine with its Renault engine that can not boast of its performance.
Also because it is a very fast circuit, and thanks to the low density of air, in 2016 Valterri Bottas with his williams managed to reach a speed of 372.5 km/h on the main straight.
Straight line of the longest, 1320m and covering the greatest distance from the first curve where very often there are bends and hairpin turns, just like last year.
FORMULA PADDOCK'S NEWS:
Sorry for the interruption, but I wanted to announce that this will be the last article for the moment in a totally free way, I have included the possibility of being able to read my articles and analyses with a small sum (the minimum that the site allowed me to do) To make it accessible to all.
Unfortunately it’s not good news, but I have thought a lot about it in these weeks of break, but with the expenses that I have and with the little time available, I made the decision to insert a small subscription.
Of course I will continue to publish on twitter, but only a summary of the most important things, and those who are subscribed will be able to read this article with more details and in a very early way.
I’m also working on new more detailed analyses, so if you’d like to subscribe here’s the link.
Now I leave you to the reading of the rest of the article, sorry for the inconvenience.
WEATHER CONDITION:
At the moment there is no rain forecast and maximum temperatures are around 22°C, so temperatures are not very hot. As for the wind condition, its speed on Friday is maximum 20 km/h, with gusts that can reach up to 35 km/h, on Saturday it increases slightly with a maximum speed of 25 km/h, with gusts that exceed 40 km/h, On race day the wind speed is just over 20 km/h, with gusts less fast than on Saturday, just over 30 km/h.
TYRE SELECTION BY PIRELLI:
We start to observe the choice of compounds: Pirelli for MexicoGp has brought the set of softer tires, this because of the little stress generated on the wheels (Pirelli reports that the degree of stress is 2), for the abrasion of the asphalt, Also 2 and for the low grip that the Mexican circuit offers.
It is to be noted however that the evolution of the track is high, so it will eraser very quickly, favoring the grip. The lateral force is also low and would also explain why the stress generated was low.
From the image above we can confirm that the stress on the tires is not high, especially for the front axle. Different situation for the rear wheels, subjected to longitudinal force during the traction phase (of which Pirelli indicates that grade 3) therefore the stress on the rear wheels is greater and this is a very important aspect for those stables that suffer a lot from the temperature management of the rear tyres.
THE REAR WING OF THE PREVIOUS EDITION:
As stated above, due to the high altitude of the circuit, the downforce requirement is very high so teams carry a high load configuration to meet this requirement.
This year, as Red Bull did in the previous year, to get a higher speed on the main straight, some teams may opt for a V-cut at the center of the flap, to reduce drag.
