Body and Chassis

The chassis includes the suspension. It supports the engine and the car body. The chassis also includes the frame, the brakes, and steering components. Older cars had heavy frames, but most cars are built today with what is known as a unibody design. This design has a floorpan and a small subframe section in the front and rear. The body includes the interior of the car, windows, door latches, the body electrical system, and the body accessories.
