ABSTRACT:
In a forward engine compartment of a vehicle a power unit is suspended so as to have a controlled rearward movement in the engine compartment when exposed to excessive forces in the lengthwise direction of the vehicle during a collision. There is at least one rear mounting having a resilient body separating two members secured to the power unit and to structural portions of the vehicle body, respectively. Said rear mounting allows one of the members a limited movement relative to the other while absorbing deformation work. As the power unit travels further back the attachment of the rear mounting is gradually destroyed, but it holds long enough to allow the power unit to hit a cowl panel at the rear of the engine compartment, thus controlling the travel of the power unit.
