咦还是没有根据啊,急死我了。。。
级别=尺寸
以下是IIHS的原话
All other things being equal, occupants in a bigger, heavier vehicle are better protected than those in a smaller, lighter vehicle. BOTH size and weight affect the forces people inside a vehicle experience during a crash. The magnitude of those forces is directly related to the risk of injury.
Weight comes into play in a collision involving two vehicles. The bigger vehicle will push the lighter one backward during the impact. As a result, there will be less force on the occupants of the heavier vehicle and more on the people in the lighter vehicle. Heavier vehicles also fare better in some single-vehicle crashes because they are more likely to move, bend or deform objects they hit.
