DRS (Drag Reduction System) is translated as drag reduction system or variable tail. The driver uses the buttons on the steering wheel to level the angle of the rear wing of the car, so that the downforce at the tail is reduced to reduce air resistance, so that the car can get faster speed and have the opportunity to overtake the car in front.
Turning on DRS will increase the vehicle speed by 10-12 km/h. Turning off DRS can increase downforce and enable better cornering.
DRS Usage Rules
-When the time difference between the following car and the preceding car is within one second, the following car can be activated
-The following car can only overtake on the prescribed track Use
in the area (DRS area)-Qualifying can use DRS
in the specified area-Cannot use
in the first two laps of the race-Cannot use
in the two laps after the safety car leaves -The front car cannot use DRS for defense.
-Can not use
in the rainy day. In addition to DRS can accelerate, KERS can also accelerate the car.
KERS (Kinetic Energy Recovery System) is a kinetic energy recovery system that recovers and stores the kinetic energy when braking, and releases the energy as auxiliary power when acceleration is needed to increase the speed of the vehicle.
KERS was launched in 2009 and discontinued in 2011. Currently using an upgraded version of ERS from KERS.
ERS (energy recovery system) consists of two parts, MGU-K and MGU-H (K stands for kinetic energy, H stands for heat).
MGU-K converts the kinetic energy generated during braking into electric energy, and MGU-H converts the heat energy in the exhaust gas into electric energy. This electrical energy can be returned to the drive system to provide more horsepower to the car.
The previous KERS and DRS were controlled by the driver through the buttons on the steering wheel, but the current ERS changes it from manual to automatic, and it can be activated under specific circumstances as needed.
