    Abstract: A motor vehicle has a bodyshell which forms a passenger cell. The bodyshell has two lateral side frames with in each case one front, lateral bodyshell pillar or A pillar. On a front side of the bodyshell, a front-end structure is formed, wherein the front-end structure has, on both sides, in each case one spring strut dome, one horizontally running support member arranged between the spring strut dome and the respective A pillar, and one support member running diagonally between the spring strut dome and a lower end of the A pillar. The two support members and the A pillar are assembled in monocoque construction from member profiles, wherein the three members form in each case one triangular load-bearing structure.
