STARTING AND DRIVING

Gearbox
The gearbox is part of the car's powertrain
(power transmission) between engine and
drive wheels. The function of the gearbox is
to change the gear ratio depending on speed
and power requirements.
The car has an eight-speed automatic gear-
box, and an electric motor for rear-wheel drive.
The number of gear changes means that the
engine's torque and power range can be used
effectively. Two of the gears are overdrive
gears that save fuel when driving at constant
engine speed. It is also possible to select
gears manually. The driver display shows
which gear position is currently in use.
