1. An actuation system (9) for facilitating opening and closing of a closure panel (13) of a vehicle (11), the actuation system comprising:
a hinge (12) coupled to a body of the vehicle and to the closure panel, the hinge having a normal mode for moving the closure panel to an open position and an active pedestrian protection mode for moving the closure panel to an active pedestrian protection position;
a first actuator (16) for actuating the hinge to move the closure panel to the open position in the normal mode;
a second actuator (300) for actuating the hinge to move the closure panel to an active pedestrian position in the active pedestrian protection mode; and
a counterbalance (308) adapted to assist with moving the closure panel;
wherein the counterbalance is adapted to assist with moving the B closure panel during both the normal mode and the active pedestrian mode; wherein
the first actuator comprises an electric motor and the second actuator comprises a pyrotechnic device; wherein
the first actuator further comprises gearing actuated by the electric motor during the normal mode, wherein the gearing is not actuated by the electric motor during the active pedestrian protection mode.
