Aerodynamics:
Every car is produced to be as aerodynamic as possible. That means that there is as little air resistance as possible. While driving, the air should flow as smoothly as possible along the sides, over the top, and under the car, with as little resistance as possible. The higher the car is, or the flatter the front is, the less aerodynamic this car will be. During the production of the car, various scale models are made and tested for aerodynamics in a wind tunnel. They are adjusted if necessary, for example with tighter lines or a different shape of the exterior mirrors. Wind is then blown over the car mixed with smoke. This makes it easy to see whether the car is aerodynamic, or whether adjustments are needed.
Aerodynamics are also taken into account for the underside of the car. There is often a lot of plastic underbody cladding under the car, and as a result the engine block and the gearbox are often no longer even visible. The underside is then almost one visible whole, where the air can easily flow past. The air then does not encounter resistance from, for example, openings, protruding parts, etc.
A sporty car is usually low and has sleek lines. The air has as little resistance as possible (see the image below).
