A mechanical energy storage system and an electric or hybrid vehicle with an energy storage system of this type are provided. The energy storage system has a planetary gear. The sun wheel of same is connected to an electric motor of the vehicle. An outer wheel of the planetary gear is connected to a wheel drive of the vehicle. The planet wheels are connected rigidly to one another via a planet wheel linkage. To increase the flywheel mass, the planet wheels have “flywheel mass regions” which have a larger diameter than a gearwheel region situated between the sun wheel and the outer wheel. Due to these flywheel mass regions, a considerable amount of rotational energy may be stored in the rotating planet wheels with the planetary gear. Such a storage of kinetic energy is intended to improve a degree of recuperation or the starting characteristics of an electric vehicle.
