Driven in high-load conditions
(e.g., when accelerating, going
uphill):
•
The Electric Motor provides
propulsion to the wheels.
•
The petrol engine drives the
generator, supplying electricity
to the electric motor for added
propulsion or to the High
Voltage battery for charging.

Engine (Direct Drive)
Driven in high-speed, low-load
conditions:
•
The petrol engine provides
propulsion to the wheels.
•
The High Voltage battery
supplies electricity to the electric
motor for added propulsion.
•
The electric motor provides electricity
to the High Voltage battery through
regenerative braking.
