You may not think an entry-level luxury sedan could claim the title of the most aerodynamic car. 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.
Is 0.27 drag coefficient good?
The 0.27 Cd Club
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 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. The drag coefficient of a vehicle is affected by the shape of body of the vehicle.
What car has the highest coefficient of drag?
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 a low coefficient of drag good?
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.
What is the drag coefficient of a f1 car?
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.
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.
Is drag coefficient constant?
The drag coefficient can depend upon velocity, but we will assume that it is a constant here . Table 1 lists some typical drag coefficients for a variety of objects. Notice that the drag coefficient is a dimensionless quantity. At highway speeds, over 50% of the power of a car is used to overcome air drag.
Is drag good or bad?
An excellent example of drag being a useful force is during skydiving: skydivers rely on drag to slow down their falls so that safe landings take place — hence, the reason for parachutes. Like any other object that moves through the air, airplanes also experience drag.
What shape has the lowest coefficient of drag?
It is generally accepted that some variation of the teardrop/airfoil shape has the lowest drag coefficient.
What is the most aerodynamic shape in the world?
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 least aerodynamic car?
You may not think an entry-level luxury sedan could claim the title of the most aerodynamic car. 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 is the drag coefficient of a teardrop?
For reference, an aerodynamically-ideal teardrop shape has a coefficient of drag of around 0.04 .
How big should drag coefficient be?
| Type of Object Drag Coefficient – c d – Frontal Area | Streamlined body 0.04 π / 4 d2 | Airplane wing, normal position 0.05 | Sreamlined half-body 0.09 | Long stream-lined body 0.1 |
|---|
How do you interpret drag coefficients?
The drag coefficient Cd is equal to the drag D divided by the quantity : density r times half the velocity V squared times the reference area A. The drag coefficient then expresses the ratio of the drag force to the force produced by the dynamic pressure times the area.
