The effect of wind on an F1 Car
As F1 cars have really sensitive aerodynamic components they are typically very sensitive to the wind, specifically the direction that the wind is blowing in regards to their direction of travel.
These wind directions can essentially be broken down into headwinds, tailwinds and sidewinds, and if there is wind at a circuit, a driver is likely going to be affected by all 3 at different points on the track.
Some circuits are more affected by wind than others namely Bahrain, Jeddah, Silverstone among others, and also some cars are more sensitive to the wind than others and that’s usually something to do with the inherent design of the car and can be tricky to try to dial out.
As the above drawing shows, this is when the wind is hitting the car head on, so it travels from the front of the car to the back.
A headwind makes it harder for the car to accelerate, meaning that they will have a lower top speed, and the car will also consume more fuel in order to try to overcome this resistance. Aerodynamic drag will also increase. However a headwind is not all bad, if a headwind occurs on a straight, it’ll actually make DRS more effective, and the increased resistance will actually help the car to slow down when braking, which allows the drivers to brake later than they would without a headwind.
A tailwind occurs when the wind is coming from the back of the car, the gusts of air will push the accelerating car giving it more speed in less time. This actually reduces the fuel consumption of the car but allows it to reach faster speeds. However when there is a tailwind, drivers have to brake earlier and they have to judge how much earlier in the moment. Also if there’s a tailwind in a corner it could result in the car experiencing a sudden loss of downforce which could case the car snap unexpectedly.
When the wind blows towards the side of the car, it is called a sidewind or a crosswind. These don’t come with any advantages unlike headwinds and tailwinds, and they are also quite hard for the drivers to predict. When the wind blows sideways it can cause the car to yaw (move left to right) which is specifically hard to deal with whilst cornering. There is also the risk of a gust of wind causing a sudden loss of downforce resulting in the car oversteering.
