A suspension support for improving collision performance, a power assembly structure, and an automobile. The suspension support includes a first sub-frame mounting portion, a suspension front arm and a power assembly mounting portion. The suspension front arm is connected between the first sub-frame mounting portion and the power assembly mounting portion. The first sub-frame mounting portion is connected to a sub-frame. The power assembly mounting portion is connected to a power assembly. The suspension support is configured to break at the suspension front arm under the squeeze of the power assembly. The suspension support is designed into a collision fracture structure, such that the suspension support may break in a collision, avoiding the power assembly impacting with a front dash panel, and solving the problem of serious collision injuries of the occupants due to the power assembly squeezing on a passenger compartment and causing serious deformation.

A motor vehicle has a forward moving direction, a rear frame having a front end and a rear end according to the forward moving direction, a driving unit comprising an engine and a gearbox, elastic suspension devices which couple the driving unit to the rear frame in an elastically oscillating manner relative to the rear frame around an equilibrium position, and a crash body for absorbing a rear crash along the forward moving direction, the crash body being fixed to the driving unit so as to project in a cantilever manner from a back of the driving unit according to the forward moving direction beyond said rear end along the forward moving direction.
