1. A hybrid vehicle, comprising:
- (a) an internal combustion engine having output at an engine shaft;
(b) a generator connected to said engine shaft, said generator including;
a first stator; and
a first rotor rotatably mounted coaxially with said first stator;
(c) an electric motor axially aligned with said engine shaft and including;
a second stator; and
a second rotor rotatably mounted coaxially with said second stator;
(d) an output gear assembly connected to an output shaft driven by said second rotor and located between said generator and said electric motor;
.[.(e) a clutch adapted to connect and disconnect said engine shaft to/from said second rotor;
(f).]. .Iadd.(e) .Iaddend.a differential gear unit driven by said output gear assembly; and
.[.(g).]. .Iadd.(f) .Iaddend.a counter shaft oriented in parallel with the output shaft, said counter shaft including gears for transmitting torque from said output gear assembly to said differential gear unit.

Abstract
A hybrid vehicle having an internal combustion engine, a generator connected with an output shaft extending from the internal combustion engine, an electric motor axially aligned with the output shaft, an output gear assembly connected to an output shaft driven by the rotor of the electric motor and positioned between the generator and the electric motor, a clutch adapted to connect and disconnect the generator to/from the output gear assembly, a differential gear unit, and a counter shaft oriented in parallel the output shaft driven by the rotor.
