A dynamically-shiftable multi-speed dual-clutch transmission (DCT) for operative connection to an engine and to an electric motor in a hybrid vehicle includes a first clutch, a second clutch, and a third clutch. The first clutch is configured to transmit torque of the engine and withstand energy of the vehicle at launch from rest. The second clutch is configured to select a first set of forward speed ratios. The third clutch is configured to select a second set of forward speed ratios alternating with the speed ratios of the first set. The second and third clutches are each configured to withstand combined torque of the electric motor and torque of the engine during shifts into the respective set of forward speed ratios, but not to withstand torque of the engine at launch or energy of the vehicle at launch.
