What is the difference between a streamlined car and a normal car?

A streamlined car is designed with an aerodynamic shape that reduces air resistance, enhancing fuel efficiency and performance. In contrast, a normal car may have a more traditional design that prioritizes aesthetics or other features over aerodynamics. The streamlined design typically results in smoother airflow around the vehicle, which can lead to better handling and lower energy consumption at higher speeds. Overall, the key difference lies in the focus on reducing drag versus a more conventional approach to vehicle design.
