F1 2023: This will be F1 in 2023: All the tech changes you should know

AndIn the second year of the new sports regulations, the most radical of this century, one cannot expect a revolution, and even more so, a readjustment of what last year was less restrictive. In sports and technical regulations These are the updates for this season in the Formula 1 World Cup.

Technical changes

new Horizons. The FIA ​​had already had to adjust the height-to-ground for the flat bottom midway through the 2022 season due to a happy ‘porpoise’ (rebound effect), which should already be further mitigated in 2023 with the new height standard: 15mm more in the middle and 10mm more on the sides.

who became In a riddle for engineers, who fear losing performance by creating a space that makes it difficult to seal off the air that passes underneath, with the consequent loss of efficiency when cornering.

The side effect is that The height of the diffuser is also raised And also the FIA ​​measure that was ordered Installing an additional sensor to monitor the “porpoise” phenomenon more effectively (The position of the impact meter is also unified) It can penalize a team that does not set its heights to what has been set this year.

The hardness of the floor itself also changes, which requires more rigidity so that it flexes as little as possible, and the strength tests will be carried out at 6 points at a time, the test being doubled at the edges. And be careful because the FIA ​​reserves the right to cancel what it deems not in accordance with the spirit of the rule.

More rigidity on the head. Cho’s massive accident at Silverstone, the incident in which he dragged across the asphalt until he ended up in the ditch, prompted the FIA ​​to strengthen the anti-roll bar. The new design calls for a rounded top on the flange, which reduces the chance of it digging into the ground during an accident, while ensuring a minimum elevation for the point of application of the smoothing test.

pregnancy test will be more rigorous, In addition to a new material that resists corrosion, The thing they don’t resist now well. In addition, there will be a new physical certification test as the load pushes the winding loop forward.

More visibility and the thing is lighter. Rearview mirrors, the reflective surface, grow by 30 percent, 5 cm more, (increased from 150 mm to 200 mm) while The minimum weight decreases from 798 to 796. You cannot weigh less, by regulations, at any time during a weekend. The engine is 151 kg.

Appointed with gasoline. this year The maximum cooling of the fuel is limited to 10 degrees below the ambient temperature in every scenario. The FIA ​​is also installing a new sensor for all teams to measure the pressure inside the tank (not the controversial flow), which should be 1 bar.

also There should be a minimum of liters To check the fuel at the end of the race and not just in practice and qualifying.

DRS cameras, transmission and helmet. In some races, DRS will be left to use from the first lap of the race on a restart (now the first two races on start and restart are prohibited for safety’s sake) and it will be tried to lead in using it 1v on the start itself.

Hitherto prohibited changes may be made in the gearboxes, as well as in the engine, for the sake of reliability, safety, or some improvement in materials without indicating an improvement in performance. those, The gear ratio can no longer be changed in the middle of the year It was also allowed in 2021 when the regulation changed. When China falls out of the calendar, the allowed tiles are again 4.

Finally the brakes, in this case the “brake by wire” will only affect the rear brakes.

Along the same lines It will be mandatory for pilots to wear a camera in their helmets with a view in their eyes What an impact they had last season. In total, there will be 7 things that can be done per shift.

Mathematical changes

6 races to race. This is the major change since doubles-doubles races on Saturdays doubled from previous years. Azerbaijan (BAC), Austria (Red Bull Ring), Belgium (Spa-Francorchamps), Qatar (Lusail), USA (Circuit of the Americas) and São Paulo (Interlagos) are the chosen venues, after extensive investigation into suitability..

And there really are a lot The accident damage allocation this short will now be a fixed amount per team, Each race weekend includes a sprint session. The amount of the allocation will double to €300,000 from 2023.

in addition to , Park-fermé weekend Sprint rules are being revised for 2023, After the FIA ​​cited a “significant increase in Parc Fermi demands” between Friday’s qualifying session and Saturday’s sprint.

Classification change in two posts. A Revised Qualifying Format (RQF) will be run at two races in 2023 to see if the format can be improved. Races haven’t been decided yet, but the shape will be He qualified in Q1 with hard only, in Q2 with medium and in Q3 with soft (all if it doesn’t rain, of course).

in these two experimental runs Only 11 sets of tires will be available For the weekend, it increased by 12 in the six dates that include the Sprint and 13 in the rest of the championship.

New solid tyres. Pirelli creates a sixth compound, although they continue to use three per race, hard, medium and soft. The new one is less rigid than C1, so the current one will be the same as C0.

Explain the penalties. Grid penalties were in the spotlight at last year’s Italian Grand Prix, where a group of drivers suffered power unit and gearbox penalties, along with the traditional penalties. She was armed A terrible mess in which no one knew where. After some confusion as to how they should be applied, the wording of the rules has been updated.

Now qualifying drivers who have accumulated more than 15 cumulative grid penalties, or who have been penalized for starting in the back of the grid, They will start behind any other qualified driver. Their relative position will be determined according to their ranking in qualification.

Fewer options to skip this mode. In order to avoid marathon days, the emphasis is still placed on comfort. The number of hours worked by F1 team members during racing weekends will be reduced in future seasons, And for now, the third of the three restricted periods (starting on Fridays) will start an hour earlier this year.

To complete the procedure, the number of curfews allowed for the first (Wednesday) and second (Thursday) will also be halved, from eight to four and from six to three, respectively. Next year they will be cut again.
