A crash-tolerant system arrangement in an engine compartment situated in the front end region of a motor vehicle includes an exhaust emission control system having an essentially cylindrical first catalytic converter housing situated in front of the exhaust gas turbocharger in the travel direction. The exhaust gas turbocharger is mechanically connected to an exhaust gas manifold via a first fastening device, and to an engine block via a second fastening device, the first and the second fastening devices being designed in such a way that a detachment of the connection of the exhaust gas turbocharger to the exhaust gas manifold and/or a detachment of the connection of the exhaust gas turbocharger to the engine block take(s) place within a predefined upper value range for the pressure force.
