1. A wheeled vehicle with a hybrid drive system, comprising:
an opposed-piston, internal-combustion engine comprising at least one cylinder, and a pair of pistons disposed for opposed sliding movement in the cylinder;
a power transducer device coupled to be driven by the opposed-piston, internal combustion engine;
a hybrid powertrain system configured to receive power from the power transducer device; and,
one of a driveshaft, an axle, and a hub flange for rotatably coupling the hybrid powertrain system to at least one wheel of the wheeled vehicle; in which:
the hybrid powertrain system comprises a first electric motor/generator device and the power transducer device comprises a second electric motor/generator device;
the opposed-piston, internal combustion engine comprises a first crankshaft, a second crankshaft, and a mechanical connection interlinking the first crankshaft and the second crankshaft;
the power transducer device further comprises a third electric motor/generator device; and
a motor shaft of the second electric motor/generator device is coupled to the first crankshaft, and a motor shaft of the third electric motor/generator device is coupled to the second crankshaft.
