Subframe

A subframe is like a special frame that helps support other things. It's kind of like how a building has a foundation to keep it sturdy. In a car, the subframe helps support the engine and the wheels. It's important because if the subframe isn't strong or if it breaks, then the car might not work right or even be dangerous to drive. So just like how you need a strong foundation for a castle made of blocks, a car needs a strong subframe to stay safe and work properly.
