Different brand products have different design concepts. On the one hand, you understand that it is one thing to reduce costs. On the other hand, when designing civil vehicles as a whole, you will consider the maximum durability of the vehicles and configure them when necessary. If it is not needed, it can ensure the stability of driving within a certain mileage, and it can be designed without configuration. At the same time, the engine room space is limited, which may be due to the overall engine room layout, and there is no battery box!
