The Circuit Hermanos Rodriguez is expected to be a medium to high speed track.
- The average speed is predicted to be 190kph, comparable to the previous event in Austin.
Simulations suggest a low percentage of the lap will be spent at wide open throttle. Just 45% of the 4.304km circuit will be taken at full throttle, less than the Hungaroring. This is due to the slow corners and the twisty Sectors 2 and 3 where the driver will maintain partial throttle rather than being flat on the pedal.
- There are two principle opportunities for the ICE to reach its maximum rotational speed. The straight from the final turn to the first corner is over 1km and the driver will be at full throttle for around 15secs. The second is the burst from Turn 3 to 4, which is another 600m and 7secs.
- The top speed is predicted be extremely high in Mexico, most likely the highest we have seen all season. Down the back straight the speed is expected to peak at over 340kph in practice and over 350kph in qualifying. The speeds are increased by the high altitude of Mexico City: at altitude the air is thinner and there is less resistance to the car.
- Another issue with the thinner air will be the ability to adequately cool the car. To get adequate air flow to the ICE water and oil radiators the bodywork will be specially designed to aid cooling.
- At an altitude in excess of 2,200m – or just under half the height of Mont Blanc – the circuit is by far the highest point of the season. By comparison, Sao Paulo is just 800m. In the normally aspirated era this would have meant a power output some 22% less than normal, but a turbocharged engine will produce the same power as a sea-level event such as Abu Dhabi. To do this, the turbo spins at a higher rate to input more oxygen into the ICE. To compare: the turbo will spin some 8% more in Mexico than in Abu Dhabi.
- The circuit will be medium difficulty for the MGU-K, with three large stops over the course of the lap. The first is Turn 1, where the driver brakes from close to 350kph to under 100kph in just under a second. The physical forces going through the car at this moment will be close to 5g.
- The second stop is Turn 4, which also comes after a long period of throttle. The turn in speed for this will be around 95kph. The final stop is Turn 12, but the entry speed for this will be in the order of 120kph.
- From Turns 6 to 13 the driver will be dancing on the throttle as he negotiates a series of esses similar to Suzuka’s famous section. With a speed ranging between 240kph and 120kph, the driver will not touch the brakes through this section, instead applying more or less pedal travel.
- Fuel consumption over one lap is expected to be quite low so energy recovery is less critical in Mexico than at other circuits.
