A micromechanical rotation rate sensor system and a corresponding manufacturing method are described. The micromechanical rotation rate sensor system includes a first rotation rate sensor unit drivable rotatorily about a first axis in an oscillating manner for detecting a first outside rotation rate about a second axis and a second outside rotation rate about a third axis, the first, second and third axes being situated perpendicularly to one another, and a second rotation rate sensor unit linearly drivable by a drive unit along the second axis in an oscillating manner for detecting a third outside rotation rate about the first axis. The second rotation rate sensor unit is connected to the first rotation rate sensor unit via a first coupling unit for driving the first rotation rate sensor unit by the drive unit.
