1. A hybrid propulsion system for a vehicle, comprising:
a battery for storing electrical energy;
a power controller adapted to route electrical energy to and from the battery;
a hybrid transaxle positioned between and interconnecting an engine and a first drive axle, the hybrid transaxle including:
a planetary gear set including a sun gear, planet gears rotationally supported on a carrier, and a ring gear, the carrier continuously connected to the engine;
a first electric motor/generator continuously connected to the sun gear of the planetary gear set;
final drive gears continuously connected to and interconnecting the ring gear of the planetary gear set to the first drive axle; and
a second electric motor/generator selectively connectable to the final drive gears through an intermediary gearset having a single gear ratio.
