What is the difference between a sedan and a three-box car?

[SanAurora]

The main differences between a hatchback and a three-box car are as follows: 1. Noise: In a hatchback, rear wheel noise is directly transmitted into the cabin. With advancements in sound insulation technology, the noise difference between the two types of cars is narrowing. Three-box cars have much better sound insulation than hatchbacks. 2. Temperature retention: When the rear hatch of a hatchback is opened, the cabin temperature is more affected by the external environment, whereas a three-box car is not affected. 3. Privacy: Large items placed in a hatchback are easily visible, while a three-box car has good privacy because the trunk is separated from the cabin. 4. Body components: Hatchbacks have a rear windshield wiper installed on the rear window, which can wipe away water during rainy days to provide clearer rear visibility, whereas three-box cars do not have this feature.
