The idea behind this project is to design a car trailer that aerodynamically and aesthetically complements the car. In addition to these characteristics, the trailer also has improved driving characteristics with independent suspension, braking, as well as parking sensors and sensors for detecting oncoming vehicles. It also has cameras that provide a complete picture behind the vehicle. The presented models are only examples that would be used in the case of Audi and BMW vehicles, which complements their aerodynamics and aesthetics.
