Presented are dual-clutch engine disconnect devices, methods for making/using such disconnect devices, and motor vehicles equipped with such disconnect devices. An engine disconnect device for a vehicle includes a first one-way clutch (OWC) with concentric inner and outer races and torque elements interposed between and transferring torque across these races in a first direction. The first outer race rigidly attaches to a damper plate for common rotation therewith, and the first inner race rigidly attaches to a pump cover of a torque converter for common rotation therewith. A second OWC, which concentrically aligns within the first OWC, includes concentric inner and outer races with torque elements interposed between and transferring torque across these races in a second direction. The second outer race is splined to the first inner race for common rotation with the pump cover. The second inner race rigidly attaches to the damper plate for common rotation therewith.
