A vehicle front suspension includes a lower suspension support structure, an upper suspension support structure, a steering knuckle and a strut. The steering knuckle has a lower end pivotally coupled to the lower suspension support structure and an upper end. The strut has an upper end connected to the upper suspension support structure, and a lower end fixedly attached to the upper end of the steering knuckle by an upper knuckle breakaway structure. The upper knuckle breakaway structure has a predetermined frangible part that releases the upper end of the steering knuckle from the strut upon application of a prescribed rearward directed force on at least one of the lower suspension support structure and the steering knuckle.
