Abstract: A vehicle includes a body including a beltline and a rear wheelhouse, an input line assembly packaged about the rear wheelhouse, a component packaged about the rear wheelhouse rearward of the input line assembly, and a spare wheel stowed rearward of the rear wheelhouse. The component is secured by a permanent beltline-side attachment and a semi-permanent rear wheelhouse-side attachment. In response to rear impact, the body is configured to allow forward movement of the spare wheel, under which the spare wheel has a trajectory relative to which the component is between the spare wheel and the input line assembly, and relative displacement between the beltline-side attachment and the rear wheelhouse-side attachment, under which the rear wheelhouse-side attachment breaks against the beltline-side attachment, and the beltline-side attachment thereafter carries the component from between the spare wheel and the input line assembly relative to the trajectory of the spare wheel.
