DRS system is an indispensable part of an F1 car, but DRS is not only a system that helps riders exceed that many people think.
The DRS (Drag Reduction System) is a system that reduces drag and reduces the grip force downforce on F1 cars placed in the rear spoiler. The system has been put into use by the FIA since the 2011 season after the F1 organizers were worried about the possibility of cars crossing each other on the track. Especially in the 2010 season, there were many cases where the cars could not pass each other, thereby creating a boring race.
Each F1 race will have 2 to 3 points to use DRS, usually the DRS trigger points will be in straight lines to help riders have a better chance of getting into the curve. However, the DRS law will have the difference between trial run, classification and main race.
At trial and grading sessions, riders are entitled to use DRS at the point of use at any time. But in the main race, drivers are only allowed to activate the DRS system when the distance between cars is only 1 second. The system will be activated during the race after the second lap (and 2 laps after finishing the safety regulation). In addition, DRS will not be activated in rainy conditions, only when the judges see the track is dry, will the DRS be activated again.
When the DRS system is activated, the flaps on the rear spoiler will open up to 85mm, thereby reducing the wind’s resistance and the speed will increase from 10-15 km/h.
Not only that, DRS not only helps riders to overcome but also helps balance the race. The problem realized from the 2010 season shows that the cars behind can not be overcome by entering the turbulent airflow of the vehicle ahead. The car behind will lose 45% of the pressure, thereby not being able to grip the road as well as the car ahead and will lose more time. Therefore, the DRS system is used to balance the advantage of the rear vehicle to pull back the lost time with the previous vehicle.
Despite receiving mixed reactions from riders and fans, it is undeniable that the DRS system helps the race more attractive.
