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 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 car has the highest drag coefficient?
With a drag coefficient of 0.20, Mercedes-Benz claims its upcoming luxury electric car, the EQS, is the world’s most aerodynamically efficient production car.
How do you calculate the 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 f1 car?
between 0.7 and 1.1
What is the most aerodynamic car?
electric Mercedes EQS
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 least aerodynamic shape?
For most practical, subsonic applications, the teardrop shape has the least “theoretical” aerodynamic drag.
What shape makes a car go faster?
The shape of the chasis is similar to an upside down airfoil. The air moving under the car moves faster than that above it, creating downforce or negative lift on the car.
What is better hp or torque?
Torque, simply, is the ability of a vehicle to perform work — specifically, the twisting force applied by the crankshaft. Horsepower is how rapidly the vehicle can perform that work. Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms.
Do spoilers make a car faster?
Spoilers are supposed to change airflow above, around and underneath vehicles to reduce wind resistance (or drag) or use the air to create more downforce and enable more grip at high speeds. As a vehicle travels faster, aerodynamic drag increases, making the engine work harder to maintain speed. …
What is the top speed of a Indycar?
380km/h
