A hybrid system, comprising: a hybrid module including an eMachine having a generator mode in which the eMachine generates energy that is stored in an energy storage system, the eMachine having a motor mode in which the eMachine draws energy from the energy storage system to provide torque, and a clutch providing a sole connection for transferring torque between an engine and a torque converter of a transmission, the clutch having an engaged state where the torque is able to be transferred between the engine and the torque converter, the clutch having a disengaged state where the torque is unable to be transferred between the engine and the torque converter; the hybrid system further comprising: a rotor hub mechanically connected to the torque converter, wherein the rotor hub and the torque converter rotate in unison together; a clutch hub mechanically connected to the engine; the clutch including clutch plates disposed between the rotor hub and the clutch hub to transfer torque between the engine and the torque converter when the clutch is in the engaged state; the rotor hub defining a piston cavity in which a piston for the clutch is slidably disposed, the piston dividing the piston cavity into an activation cavity and a deactivation cavity; characterized by the piston having an offset section bumped out from the rest of the piston in which portions of the piston facing the activation chamber and the deactivation chamber have similar effective areas so that the clutch is centrifugally neutral; the clutch including a deactivation fluid passage that supplies fluid to the deactivation chamber; and the rotor hub including a spillover gap proximal the deactivation fluid passage that allows excess fluid to spill over to prevent hydrostatic lock of the piston. a hybrid module including an eMachine having a generator mode in which the eMachine generates energy that is stored in an energy storage system, the eMachine having a motor mode in which the eMachine draws energy from the energy storage system to provide torque, and a clutch providing a sole connection for transferring torque between an engine and a torque converter of a transmission, the clutch having an engaged state where the torque is able to be transferred between the engine and the torque converter, the clutch having a disengaged state where the torque is unable to be transferred between the engine and the torque converter;
