Abstract: A motor vehicle with a combustion engine (2), a transmission (8) and a mechanical drive line (6) comprises a coaxially disposed electric generator (10) for providing power to electric loads, said generator being coupled directly with the crankshaft (4) of the combustion engine. The rotor of the generator serves as a flywheel in particular when the generator is designed in outside rotor construction. Stator and rotor of the generator are each formed as hollow cylinders and have a small axial length in comparison to the mounting diameter of the generator. The generator can also be used as a starter motor when operated as a motor. An additional possibility of application is for damping the torsional vibration of the crankshaft of the combustion engine, the transmission and the mechanical drive line.
