Last Updated on September 1, 2023

In a Formula 1 race, a driver can use DRS when they are within one second of the car in front of them on the straight. This is known as the “DRS detection zone” and is measured at specific points before a DRS zone using sensors that can accurately measure the time gap between cars down to one-thousandth of a second.

Since its debut in 2011, the Drag Reduction System (DRS) has been a contentious tool utilized in Formula 1 racing. When running within a second of the car in front, the system involves the driver deploying a flap in their rear wing to minimize drag and increase top speed. DRS is meant to help overtaking and increase audience excitement during racing, but both F1 drivers and fans disagree with the technology. The purpose of DRS in Formula One will be discussed, along with how it functions, when it can be used, and any limitations.

What does DRS aim to achieve?

DRS’s main objective is to facilitate overtaking. With the ability to dump rear wing drag through a gap that can open when a car is running within one second of the car in front, it was developed in 2011 to make overtaking simpler. Even when driving alone on the circuit during practice and qualifying, drivers can use the technology. The gadget is frequently criticized since it intentionally gives drivers an advantage over competitors who are driving in front of them, detracting from the ability required to execute a difficult overtaking technique.

How Does DRS Function?

DRS works by raising a flap on the vehicle’s rear wing, which lowers drag and raises the peak speed. To increase aerodynamic grip, the flap is closed as the driver brakes or makes a turn. Drivers benefit from DRS to varying degrees depending on the particular track, but on average it is thought to increase speed by about 10–12 km/h (6-7 mph).

When Is DRS Useful for Drivers?

During the duration of a Formula 1 race, a driver may utilize DRS if they are on the straight and less than one second behind the car in front of them. The “DRS detection zone” refers to this area. The driver can turn on the DRS and use it to try to pass the vehicle in front once they approach the DRS activation zone, which is a specified straight on the course. However, during the first two laps of a race and during qualifying, drivers are not permitted to use DRS.


The Drag Reduction System (DRS) is a crucial tool used in Formula 1 racing to promote overtaking and wheel-to-wheel competition. There are several limitations on how the technology may be used, but it does allow drivers to minimize drag and increase top speed while running within a second of a car in front. Despite the criticism surrounding it, DRS is still a crucial component of the sport and is probably going to be employed in F1 racing going forward.
