What does DRS mean in Formula 1?

DRS is an important feature of Formula 1 racing. What does it mean? Who can use it? And why has it had such an impact on F1?

While watching Formula 1 races, you have no doubt heard the phrase “DRS is very powerful”.

Indeed, DRS is one of the most important factors in F1. It allows the driver to overtake. That is often the difference between winning the race or second place.

But what exactly does it mean?

F1 explained: What does DRS mean in Formula 1?

DRS stands for “Drag Reduction System”. It’s really a system designed to reduce drag, just as you might imagine, and it’s a feature of the rear wing of every Formula 1 car.

Basically, the rear spoiler is adjustable. In the closed position, it provides downforce, which improves traction through corners. In the open position, it allows air to pass through, reducing vehicle drag. Opening the wings in a straight line allows for a higher top speed.

Drivers can use the DRS (open or close the rear wing) at any time during practice or qualifying, although they really only gain an advantage in a straight line.

During racing, the use of DRS is restricted to designated sections of the road known as DRS zones. Drivers are only allowed to open the rear spoiler in those areas if they are within one second of the vehicle in front. This allows for a greater chance of a pass.

Since a vehicle with an open rear wing has an advantage over a vehicle in front with (probably) closed wings, the driver in front must try to keep a chasing vehicle out of DRS range while the driver behind must Try to go within DRS to have a chance to pass.

What is the DRS train in F1?

Sometimes races end with something called a DRS train. That’s when multiple cars are picking DRS from each other.

For example, a Red Bull is leading a Ferrari, close enough to trigger DRS. However, behind the Ferrari is a Mercedes that is also close enough to the DRS. In that case, Mercedes no longer really has an advantage over Ferrari as both have open rear wings. Overtaking becomes more difficult in that situation.

DRS is not allowed during the first two laps or after a safety car restart. It is also disabled in wet weather conditions.
