A camshaft phaser assembly, including: an axis of rotation; a hydraulic camshaft phaser including a stator arranged to receive rotational torque and including a plurality of radially inwardly extending protrusions, a rotor arranged to be non-rotatably connected to a first camshaft and including a plurality of radially outwardly extending protrusions circumferentially interleaved with the plurality of radially inwardly extending protrusions, and a plurality of chambers bounded at least in part by the plurality of radially inwardly extending protrusions and the plurality of radially outwardly extending protrusions; an electric camshaft phaser including an output gear arranged to be non-rotatably connected to a second camshaft located concentrically within the first camshaft and an input non-rotatably connected to the stator; and a connection plate non-rotatably connecting the input and the stator. The rotor and the output gear are rotatable with respect to each other about the axis of rotation.
