Abstract

A drive system for a vehicle comprises an internal combustion engine and a torsional vibration damping arrangement. The internal combustion engine is switchable between operating modes of different performance capability, and the torsional vibration damping arrangement comprises a flywheel mass arrangement and at least one deflection mass pendulum unit with a deflection mass carrier and a deflection mass arrangement supported at the deflection mass carrier such that it can deflect out of a basic relative position with respect to the latter by means of a deflection mass coupling arrangement.
