Can Perfume Be Placed in the Car?

Yes, but placing perfume in the car may cause an explosion, so it is recommended not to do so. Here are the relevant details: 1. Types: Car perfumes can generally be divided into three types: liquid, solid, and spray. Solid perfumes are inexpensive, come in cute and diverse designs, and are favored by young car owners. 2. Effects: High-quality car perfumes have long-lasting fragrances and can kill bacteria, but if chosen improperly, under the heat dissipation conditions of the air conditioning, they can not only affect the mood of people in the car but also their health. 3. Hazards: If low-quality perfumes are used, they not only fail to improve air pollution in the car but can also worsen it. Low-quality perfumes contain excessive levels of alcohol and fragrance, with overly strong scents that can cause dizziness, nausea, and other adverse effects on the human body.

BMW X1 has a four-wheel drive version. The four-wheel drive models are the BMW X1 2021 xDrive25Li Premium and the BMW X1 2020 xDrive25Li Premium.
