What production car has the lowest coefficient of drag?
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 a typical coefficient of drag?
The drag coefficient of an object in a moving fluid influence drag force
| Type of Object | Drag Coefficient – cd – | Frontal Area |
|---|---|---|
| Person standing | 1.0 – 1.3 | |
| Bike – Upright Commuter | 1.1 | 5.5 ft2 (0.51 m2) |
| Thin Disk | 1.1 | π / 4 d2 |
| Solid Hemisphere flow normal to flat side | 1.17 | π / 4 d2 |
How do you calculate drag coefficient on a car?
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.
What is the drag coefficient of a Prius?
It slips through the air with a remarkable drag coefficient of just Cd 0.25, which has secured its position as the world’s most aerodynamic hatchback as well as one of the most instantly recognisable.
What is the best 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.
What is a bad drag coefficient?
Usually if a carmaker is bragging about it, it’s in the low region, somewhere between 0.26 and 0.22 – and the lower the number, the better.
What is a high drag coefficient?
A low drag coefficient implies that the streamline shape of the vehicle’s body is such as to enable it to move easily through the surrounding viscous air with the minimum of resistance; conversely a high drag coefficient is caused by poor streamlining of the body profile so that there is a high air resistance when the …
What is the highest possible drag coefficient?
According to Sighard Hoerner’s Fluid Dynamic Drag, this would be the half-sphere with the open side exposed to the wind. Its drag coefficient is 1.42. A rod with a hemispherical cross section will even have a drag coefficient of 2.3 (right column in the graph below).
Which car has the best coefficient of drag?
How is drag calculated?
The drag equation states that drag D is equal to the drag coefficient Cd times the density r times half of the velocity V squared times the reference area A. Drag coefficients are almost always determined experimentally using a wind tunnel.
What is the drag coefficient of Tesla Model 3?
0.23
The shape has purpose, though—the Model 3 has a drag coefficient (Cd) of just 0.23, lower than almost any other production car, although a little worse than CEO Elon Musk’s original target of just 0.21.
