In the recent race, a record pitstop phase was set up for only 1.89 seconds by the British F1 racing team. Let's find out, why workers can serve cars so fast?
In each race, we often only care about the drivers and the cars they control. But to be able to participate in the race and win, each fleet cannot lack pitstop.
The total length of the race is about 300km, each race car will need at least one stop at the maintenance site (pitstop) to change tires and modify the car. As soon as the driver pulled into the pitstop area, about a dozen workers rushed out, lifted the car, replaced all four wheels, wiped the glass, lowered it, and the car launched and continued the fierce race. The whole process usually takes less than 10 seconds.
In order to do that, workers need absolute precision, coordinating effortlessly to do the job in the shortest time possible because the slow time of a millisecond can also decide to win both. fleet.
With the Nascar track, a team of up to 6 people needs 11 to 13 seconds to replace four tires for a pitstop. Even with long races like Le Mans 24 Now the pitstop takes longer but never takes a minute.
In the European Grand Prix race in Baku, Azerbaijan took place last June, the British F1 team Williams set a new record when making a pitstop phase at a glance, costing only 1.89 seconds. The previously set record break was 1.92 seconds of Red Bull racing team at US Grand Prix, Texas in 2013.

So, what happened to the pitstop with the cars?
For F1 racing, the car will be driven by a rider into a small stop lane, just before the waiting stand has been loaded at a speed of about 60km / h. This requires extremely high precision, riders have to stop the car extremely accurately to not hit the waiting workers. A person will lift the car with a hydraulic lift and the other two members will balance the sides of the car.
As soon as the car stopped, 12 workers would simultaneously change four wheels. Each tire will have 3 people waiting, one will remove the wheel nut with the pneumatic screw gun, the wheel is removed, the new wheel is installed and the person holding the gun is ready to tighten the belt.
With the long race, the car will be filled with fuel, which can change the driver and with some vehicles, with some types of light and glass cars will be cleaned.
There are skillful mechanic teams, the car has not stopped completely, it can twist the gun valve to the nut. This, which requires absolute accuracy because of the powerful torque of these guns, only a small mistake when used can lead to very serious injuries.
When the gun leaves the wheel, the mechanic will check it carefully to make sure everything is ready, who will signal the car to join the track.
Grounding vehicle, lifters and car regulators quickly leave as soon as the pit road lights are bright, the car rushes into the track.
The speed of the pitstop has reached its peak, always hovering at the threshold of two seconds, even less than two seconds.
Why, can they achieve such a short time?
In order to achieve such a time record, the fleets all have terrible training time. Pat Symonds, chief technology officer of Williams F1, said his team made about 1700 pitstop phases each season including workshops at the weekend.
Besides, the FIA (World Automobile Federation) introduced a law to ban gasoline pumping in F1 tournament from the 2010 season and it also suggested that the pitstop time reduced significantly.
The pumping of more fuel to help things happen more safely, faster, because in the past there have been a few fire accidents occurred. In 1994, at the German GP circuit, Jos Verstappen's car was engulfed in fireballs. In 2009, in Brazil GP, Kimi Räikkönen's car caught fire.
Difficult to imagine in the next years, how will the pitstop grow? Can the pitstop's time be reduced to 1.5 seconds? Let's wait, it will definitely be interesting.
