Methods of decreasing the drag coefficient of a vehicle include re-shaping the rear end, covering the underside of the vehicles, and reducing the amount of protrusions on the surface of the car.

How do race cars reduce drag?
The low-pressure zone behind the vehicle is reduced, thus less turbulence is created, which subsequently leads to drag reduction (Fig. 2). The wing is another essential aerodynamic device often used by race cars. ... But using a wing may add up the drag to the vehicle body.
How can you reduce drag?
Ways to reduce it include using the handlebar drops or aerobars. Getting down low into a crouched position with elbows in reduces drag because there is a more streamlined shape and there is less frontal area.
How does drag affect a race car?
Aerodynamic drag is one of the main obstacles to accelerate a solid body when it moves in the air. When a racing car or road vehicle burns fuel to accelerate, drag force pulls it from back to reduce the speed and hence the fuel efficiency is adversely affected.
How do f1 cars reduce drag?
The most commonly used tactic is to simply run smaller wings to cut drag. The cars in some cases having almost no rear wing at all. The picture below is the wing Ferrari used at Monza in 2009. Now compare it to the wing used on the same car at other races (below).
What does it mean to reduce drag?
Drag reduction is a physical phenomenon that causes friction to be reduced and fluid flow to be increased. Chemicals that reduce drag are known as drag-reducing agents (DRA). Several polymeric compounds can reduce the wall shear stress of flowing liquids at low concentrations.
What affects drag?
Some factors that impact the magnitude of air resistance (drag) include the size and shape of the object, the velocity of the object and the air, and other properties of the air such as its viscosity, mass, and compressibility.
How can you reduce drag and friction?
Friction drag can be reduced by delaying the point at which laminar flow becomes turbulent. This can be accomplished by smoothing the exposed surfaces of the aeroplane by using flush rivets on the leading edges and through painting, cleaning, waxing, polishing or the application of surface coatings.
How do rockets reduce drag?
Drag depends on the cross-sectional area of the object pushing through the air. Making a rocket as narrow as possible is the best way to reduce drag. The speed of a rocket through the air similarly increases drag.
How does drag affect car speed?
Aerodynamic drag increases with the square of speed; therefore it becomes critically important at higher speeds. Reducing the drag coefficient in an automobile improves the performance of the vehicle as it pertains to speed and fuel efficiency. There are many different ways to reduce the drag of a vehicle.
How do airplanes reduce drag?
Engineers reduce friction drag by making the airplane more streamlined, the wings narrower, or by using new materials that make the surface more smooth, decreasing the ability for the force of drag to effect it. As the roughness and surface area of the airplane decreases the friction drag will decrease.
Why does downforce increase drag?
For a given aerofoil, increasing lift (downforce) will give a corresponding increase in drag. This is because to increase lift you increase the angle of attack. The teams will look at the car in terms of L/D (the ratio of lift (downforce) to drag).
Why do F1 cars have high drag?
Typical Formula 1 car drag coefficients are between 0.7 and 1.1, depending on the circuit the car is set up for. ... A lot of this drag is due to the wings but a lot of it is due to the uncovered wheels.
What causes drag on an F1 car?
Skin friction drag is caused by the actual contact of the air particles against the surface of the moving object. The layer above these attached particles slides over them, but is consequently slowed down by the non-moving particles on the surface. The layers above this slowed layer move faster.
Why don t F1 drivers use DRS all the time?
The reason DRS is not available to use in all parts of the track is because the rear wing is there for a reason, and that is aerodynamics. This helps generate downforce that pins the car to the ground and keeps it from sliding or losing traction while cornering (when the lateral forces are acting on the car).
