Aerodynamics:
Every car is manufactured to be as aerodynamic as possible. This means that there is as little air resistance as possible. During driving, air must pass as smoothly as possible along the sides, top, and underside of the car, with minimal resistance. The higher the car, or the flatter the front, the less aerodynamic it will be. Various scale models of the car are made during production and tested for aerodynamics in a wind tunnel. They are adjusted as needed, with tighter lines or a different shape of the side mirrors, for example. Wind mixed with smoke is blown over the car to visibly test its aerodynamics and to determine if adjustments are required.
Aerodynamics are also considered for the vehicle’s underside. There is often a significant amount of plastic undercarriage shielding below the vehicle, making the engine block and transmission barely visible. The underside becomes almost a single, seamless piece, allowing air to flow easily without resistance from openings, protruding parts, etc.
A sporty car is usually low and has sleek lines, minimizing air resistance (see the image below).
