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 good drag coefficient for a car?
between 0.25 and 0.3
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=0.350.45. The drag coefficient of a vehicle is affected by the shape of body of the vehicle.
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.
Do Formula 1 cars have a low drag coefficient?
Despite all the best efforts of Formula 1, Indy car etc designers, the drag of such cars is very high. ! 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 shape has the lowest coefficient of drag?
streamlined symmetric airfoil
A quick comparison shows that a flat plate gives the highest drag, and a streamlined symmetric airfoil gives the lowest drag–by a factor of almost 30! Therefore, we can conclude that: Shape has a very large effect on the amount of drag produced.
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.
Is a higher 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.
What is the drag coefficient of a Prius?
Cd 0.25
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 drag coefficient of the Tesla Model 3?
0.23
The shape has purpose, thoughthe 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.
Can coefficient of drag be greater than 1?
It’s only approximately constant. For example the drag coefficient of a sphere can vary depending on the speed and can have values greater than 1 at low Reynolds numbers.
How heavy is an F1 car?
F1 car weight over the years
| Year | Weight |
|---|---|
| 2017 | 728 kg |
| 2018 | 734 kg |
| 2019 | 743 kg |
| 2020 | 746 kg |
What is F1 drag?
F1 Technique: Explaining the activation of the Drag Reduction System (DRS)The rear wing of an F1 car is designed to generate downforce (pushing the car down) but as a consequence it also produces massive turbulence called drag. And drag reduces the top speed of the car.
How do F1 cars reduce drag?
In Formula One, the DRS opens an adjustable flap on the rear wing of the car, in order to reduce drag, thus giving a pursuing car an overtaking advantage over the car in front. The FIA estimate the speed increase to be between 1012 km/h by the end of the activation zone.
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.
Can a drag coefficient be negative?
When drag is termed “positive”, that means that it is exerting a force against the force of thrust. Negative drag means the opposite, that there is a reduction in the drag force.When drag is negative, we can assume it is accelerating.
What is the highest 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.
How do you lower drag coefficient?
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?
Drag coefficient can be fairly constant over a wide range of Reynolds numbers and then abruptly shift to a different value due to the change in the boundary layer turbulence, for example. My favorite example of his is the Drag crisis .
Does size affect drag coefficient?
Effect of Size on Drag. The amount of drag generated by an object depends on the size of the object.Like the other aerodynamic force, lift, the drag is directly proportional to the area of the object. Doubling the area doubles the drag.
What is the drag coefficient of the Tesla Roadster?
0.31
Tesla has been working on the original roadster occasionally, for example giving it an aero kit in 2014 which reduced its drag coefficient down from 0.36 to 0.31. The new Roadster has some killer specs. As it so happens, that’s exactly its purpose.
What is the drag coefficient of the Tesla Model Y?
0.23 Cd
With the instant electric torque and acceleration, driving a gas car feels like old technology, according to Gali. Gali also points out the fact that besides being bigger than the Model 3, Model Y has the same drag coefficient of 0.23 Cd that’s a noteworthy engineering achievement on the part of Tesla.
