Usually attached just behind the front axle or around the rear axle and diffuser, these fences are known as aerodynamic rakes and measure the air pressure over the car at any one point.
One aspect of the old cars that has already been swept away is the high-rake concept most notably used by Red Bull, which saw the car run with the rear jacked up in the air while the front would run close to the ground. F1 managing director Brawn has played a key role in forming the new regulations for 2022.
What is negative rake on a car?
Positive rake is where the front of the car is lower than the rear, and negative rake is where the rear of the car is higher than the front. In pretty much all modern race cars, you will want to lean towards positive rake.
It is the distance between the bottom of the car and the ground, measured at the front and rear. If the rear is taller (more distant from the ground) there is said to be a positive rake. If the front is taller there is negative rake, which is seldom if ever used real life (F3).

How does rake affect car handling?
Rake helps the aerodynamics of the car work efficiently, lowering the nose but allowing the floor of the car to interact effectively with the airflow around it.
What does raking a car mean?
How do you find the drag force of a car?
F = ma or a = F/m
Since these forces are equal and opposite, the net force on the car is zero, so the car maintains its constant speed. If you take away the force produced by the engine (by putting the car in neutral, for instance) then the only force on the car is the drag.
How do you find the drag coefficient of a car?
How do I find the frontal area of my car?
One rule of thumb way for a car, is to measure the width and the height and multiply them to get an area. 85% of that area will equal the cars frontal area.
What is a good drag coefficient for a car?
The average modern automobile achieves a drag coefficient of between 0.25 and 0.3. Sport utility vehicles (SUVs), with their typically boxy shapes, typically achieve a Cd=0.35–0.45.
To have a drag coefficient of under 0.28 is truly a feat, especially for a car regular car which was designed on a budget, for a budget. Here we find models like Toyota’s current Auris, with 0.277. And even the seventh-gen VW Golf is a top aero performer, with a measured 0.27 Cd.
What reduces drag on a car?
Spoiler is one of the most widely used and important aerodynamic devices in the automotive domain. Its main purpose is to “spoil” the unwanted airflow and channel the airflow in order, which helps in reducing the drag.
What is the drag coefficient of a Tesla?
Our initial simulations calculated a drag coefficient of 0.48, which is more than double the drag of the Tesla Model 3 (Cd of 0.23).
What is the drag coefficient of a Bugatti Chiron?
The Bugatti Chiron has a drag coefficient of around 0.36. That’s not very impressive, but then again, sports cars are usually aiming for good downforce & style. An F1 car, for example, has a terrible drag coefficient of around 1.00, as it has enough power to overcome the drag penalty in favor of more downforce.

What is the drag coefficient of a Porsche 911?
The drag coefficient (cd) of the 911 Turbo S varies depending on the aerodynamic setting. The most efficient configuration with the minimum cd value of 0.33 is achieved with closed flaps and retracted front and rear spoilers.
2022 Update: We have been informed that the Mercedes EQS got the title.

What is the drag coefficient of a Tesla Model 3?
A perfect example of this is the Tesla Model 3, which has a drag coefficient of just 0.23 – making it the most aerodynamic standard roadworthy car in the world.
Is Mercedes EQ the most aerodynamic car ever?
World’s Most Aerodynamically Efficient Car
The figure also makes EQS, the most aerodynamic road car from Mercedes Benz ahead of its A-Class saloon and 7th-generation S-Class.
What is the most aerodynamic thing on earth?
For speeds lower than the speed of sound, the most aerodynamically efficient shape is the teardrop. The teardrop has a rounded nose that tapers as it moves backward, forming a narrow, yet rounded tail, which gradually brings the air around the object back together instead of creating eddy currents.
