What is a good coefficient of drag?
Typical drag coefficients 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. The drag coefficient of a vehicle is affected by the shape of body of the vehicle.
What race car has the lowest drag coefficient?
But according to Mercedes, the new A-Class sedan features the lowest drag of any production vehicle in the world, with a coefficient of 0.22. At this level, it defends the world record held by the Mercedes-Benz CLA.
What car has the highest drag coefficient?
The electric Mercedes EQS is the world’s most aerodynamic production car. Its 0.20 drag coefficient beats the Tesla Model S and Lucid Air. The cab-forward design isn’t just for good looks.
Is higher or lower drag coefficient better?
A low coefficient is conducive to high top speed and low fuel consumption, while a higher drag coefficient is generally found in cars searching for high cornering speeds influenced by downforce. It shows that a car’s coefficient of drag can be found by analysing the drag force acting on the car at a given speed.
How can drag coefficient be reduced?
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.
What is the most aerodynamic shape?
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.

What is the most aerodynamic muscle car?
The limited production Volkswagen XL1 is the most aerodynamic car produced by a major manufacturer to date, with a cD of 0.186, but was only offered in Europe. Our list of the 10 Most Aerodynamic Cars Sold in America takes ties into account, with cDs that range from 0.24 through 0.27.
What is the most effective way to reduce the drag coefficient?
The most effective way to reduce the drag of a supersonic airfoil is to reduce its thickness.
Can drag be reduced using aerodynamics?
It has been found that aerodynamic drag can be influenced by using different add on devices. In consideration to reduce drag, it is favorable that the flow is attached to the vehicle’s body as long as possible. A streamlined body would result in less flow separation, which would cause less turbulence.
Why is reducing drag important?
Aerodynamic drag reduction plays an important part in achieving fuel consumption targets. These include increased fuel efficiency, better cooling, improved engine compartment packaging and lower production costs.
