What Causes the Smell of Leather in the Car?

[Jean]

It is normal to smell leather in the car. Here are specific explanations for the smell of leather in the car: 1. For new cars: It is generally normal for new cars to have this smell. Various rubber/plastic components in new cars are fresh and may produce this odor under high temperatures, which will gradually fade away until it becomes unnoticeable over time. 2. Someone burning materials near the car: If rubber or plastic products are being burned nearby, this smell may be produced and enter the car through the external air circulation system. 3. Mistaking gasoline smell for burning rubber smell/incomplete combustion: For example, when starting the car in winter, due to low temperatures, it becomes harder to atomize gasoline, affecting combustion. Some unburned gasoline molecules may exit through the exhaust pipe and then enter the car via the external air circulation system.
