Method manual for the Belgian Grand Prix

F1 Grand Prix, GP Belgium, Circuit de Spa-Francorchamps

Thanks to the difficult weather conditions on Friday, when the two follow periods took location in moist disorders, groups and Pirelli have been not able to assemble as considerably knowledge as they desired, leaving both equally the a single-cease and two-cease tactic a practical solution for today’s Belgian Grand Prix. F1Technical’s Balázs Szabó analyses the feasible race techniques for the Spa race.

For the very first of the remaining 9 races, the Belgian Grand Prix, Pirelli has preferred the 3 compounds in the center of the vary: C2 as the P Zero White tough, C3 as the P Zero Yellow medium, C4 as the P Zero Pink comfortable.

The seven.004km Spa-Francorchamps is a single of the most demanding circuits for tyres on the calendar, that includes notably higher lateral masses. The well-known Eau Rouge-Raidillon intricate is just a single of the areas in which tyres are subjected to a number of forces: pushed into the floor by downforce and compression, though cornering at the exact same time.

The monitor has long gone via number of modifications for this 12 months with new asphalt laid among Turns two and four, and Turns eight and nine, with the bumps taken out and enhanced grip. In addition, gravel traps have been extra shut to the monitor at Turns one, six, seven, and nine. The gravel characteristics sharp stones, and there are also some sharp edges shut to the concrete kerbing.

So significantly weather conditions disorders have been variable, but the race is anticipated to acquire location in much more secure and hotter disorders. With rain distracting the lengthy operate simulations in Cost-free Observe two, most of the groups carried out major gas race operate simulation in yesterday’s last follow, albeit it took location in pretty chilly disorders, which means that the knowledge collected could be deceptive when it will come to race tactic.

Centered on the simulations and knowledge from earlier a long time, Pirelli thinks that the forty four-lap Belgian Grand Prix can be tackled with possibly a a single-cease or a two-cease tactic. It was attention-grabbing to see on Friday that there was pretty a massive effectiveness distinction among the tough and the comfortable compound with the image reminiscent of what we noticed at the Hungaroring with motorists not able to heat the tough compound up adequately.

Even if disorders are much more secure and hotter right now, it could be dangerous to generate a tactic close to the tough compound as motorists could confront very similar troubles that prevented Charles Leclerc from securing a at ease acquire at the Hungarian Grand Prix.

In accordance to the Milan based mostly tyre provider, the a single-cease tactic is a much more conservative solution which could be recognized in unique permutations.

Setting up on the P Zero Yellow medium is the most adaptable method, which offers the solution to swap to possibly the P Zero White tough or the P Zero Pink comfortable as section of a a single-stopper, though leaving the doorway open up for a two-stopper if essential.

One more permutation for a a single-stopper is to begin on the comfortable, but it needs possibly an early cease for the tough or cautious administration to then go on the medium.

A unique and much more intense method could be to use the comfortable as a section of two-stopper, potentially with two stints on the medium tyre. This may compromise monitor situation but could be a great solution for a rapid motor vehicle if there is a security motor vehicle, or degradation on the comfortable turns out to be pretty higher.
