They have a streamlined bonnet so that the air will be pushed over the car.
so that the car will go faster and thecorners and the distence from the ground makes it streamlined .The rounder the corners the more streamlined it is
By designing the car to be as streamlined as possible.
after market body panels.
Wind tunnel test
It's mainly to reduce fuel consumption. A streamlined shape needs less energy to push it forward against standard air pressure - than one that isn't streamlined.
A streamlined car reduces air resistance, known as drag, which allows the car to move through the air more efficiently. This results in less energy being needed to maintain speed, enabling the car to travel faster.
To reduce air friction.
Every part of the car exposed to the air-stream except the tires
The new software is very streamlined.We need to make sure it is all streamlined and perfect.
A streamlined car would be more efficient than the same car without streamlining as it would present less drag. Unfortunately, streamlining by itself does not make a car efficient. Efficiency is the product of may different things such as the type of and inflation of the tires, the size and efficiency of the engine and etc.
To reduce friction and fuel consumption not to mention making it pleasing to the eye.
