A car frame is the structural foundation of a vehicle, providing support and shape. It is typically made from materials like steel or aluminum, designed to withstand various forces during driving. The frame holds all the essential components, including the engine, suspension, and body, ensuring they work together effectively. The design of a car frame can vary significantly between different types of vehicles, such as sedans, SUVs, and trucks. A well-constructed frame enhances safety by absorbing impact during collisions and contributes to the overall performance and handling of the car.
