The term "underbody" refers to the underside of a vehicle, including the chassis and components that support the structure. It plays a crucial role in the vehicle's overall stability, safety, and performance. The underbody houses essential parts such as the exhaust system, fuel tank, and suspension components, which are vital for the vehicle's operation. In addition to its functional aspects, the underbody is also important for aerodynamics. A well-designed underbody can reduce drag and improve fuel efficiency. Many modern vehicles, including electric cars and sports cars, feature streamlined underbodies to enhance performance and reduce wind resistance.
