All-wheel drive*

All-wheel drive, AWD (All Wheel Drive), means
that the car is driving all four wheels at the same
time, which improves traction.
To achieve the best possible traction, the motive
force is distributed automatically to the wheels
with the best grip. The system continuously cal-
culates the need for torque to the rear wheels,
and can immediately redistribute up to half of the
motor's torque to the rear wheels.
All-wheel drive also has a stabilising effect at
higher speeds. Under normal driving conditions,
the majority of power is transmitted to the front
wheels. When stationary, the all-wheel drive is
always engaged in preparation for maximum trac-
tion during acceleration.
All-wheel drive characteristics vary depending on
the selected drive mode*.
