Driving systems
Twin Engine Plug-in Hybrid vehicles are parallel
hybrids, which means that they have two sepa-
rate drive systems: an electric motor and a gaso-
line engine.
Two drive systems
Depending on the drive mode selected and the
amount of electric power available in the hybrid
battery, the two systems can be used in tandem
or separately.
The electric motor is powered by a hybrid battery
located under the tunnel console. This battery
can be charged from a wall socket or special
charging stations. The gasoline engine can also
charge the hybrid battery using a special high-
voltage generator.
The gasoline engine and electric motor both gen-
erate power directly to the wheels. A control sys-
tem coordinates both of the drive systems to help
optimize driving economy.
Hybrid battery: stores electrical current,
which is provided by connecting the charging
cable to the electricity grid, through regener-
ative braking or from the high-voltage gener-
ator. This makes it possible to drive using the
electric motor or to power the electrical air
conditioning to precondition the passenger
compartment.
Gasoline engine: starts when the charge
level in the electric motor is too low to pro-
vide the power output that the driver requires.
High voltage generator
2
: charges the hybrid
battery and starts the gasoline engine. It can
also provide the gasoline engine with extra
electrical current.
Electric motor: powers the vehicle using
electricity and can provide extra torque and
power during acceleration. It combines with

Combined generator and starter motor (Crank Integrated Starter Generator).
