The back part of a car is most commonly called the rear section or rear end. However, this area is made up of several specific components, each with its own name and function. The main storage compartment is the trunk in a sedan or the cargo area in an SUV, hatchback, or minivan. The vertical panel that opens to access this space is the trunk lid or liftgate. Below that, the rear bumper protects the vehicle's body from minor impacts. The most visible parts are the taillights, which include brake lights, turn signals, and reverse lights. Above the trunk, you have the rear windshield (back window), and at the very top, the roof spoiler on some models, which improves aerodynamics.
Understanding these terms is useful for everything from describing a minor fender-bender to shopping for accessories. For instance, if you need to replace a broken light, knowing it's called a "taillight housing" will get you the right part faster. The design of the rear end also significantly defines a car's body style; a hatchback has a large, single rear door that includes the window, while a sedan has a distinct trunk separate from the window.
