What is the raised section in the middle of the car's rear row called?
1 Answers
Sedan rear row middle raised section is to maintain chassis flatness. Since the car's underbody chassis has exhaust pipes or drive shafts, usually rear-wheel-drive cars must transmit engine power to the rear wheels through the drive shaft, so structurally this raised section is necessary. Below are specific introductions to related content: 1. The car adopts front-engine rear-wheel-drive layout: The middle section needs to accommodate the drive shaft. The front-mounted engine transmits power to the rear wheels through the drive shaft. If the drive shaft is too low, it may easily scrape the ground, affecting the car's passing ability. If the body height is increased, it will affect the car's center of gravity. Therefore, the local floor needs to be made into a raised shape to protect the car's drive shaft and improve the car's stability, passing ability and handling. 2. The car chassis design is relatively low: The car may be front-wheel-drive, but needs to pass the exhaust pipe, so the middle raised section provides space for exhaust pipe design. 3. The car is front-wheel-drive: But the car chassis uses rear-wheel-drive platform, or shares a platform with its own high-end models (rear-wheel-drive platform), resulting in the raised section in the middle of the car's rear row.
