is
powered by both the gasoline eng ine
and the electric motor when in fu
ll
acceleration.
Boost is only available for a short time because it
uses
a large amount of energy. Availability
de-
pends
on the high-voltage battery charge level.
Coasting
The gasoline engine switches
off
and disengages
at speeds up to approximate ly 112 mph
(180
km/h)
if the acce lerator pedal
is
not press-
ed and the D position is selected. Driving conser-
vatively like this can reduce fuel consumption
.
Energy recovery
(recuperation)
When braking, the electric motor will act as a
generator creating electric energy that
is
then
stored in the high-voltage battery
.
This also oc-
curs when the vehicle is coasting or driving down-
hill.
If the brakes are applied early and evenly, the
electric motor
will
brake the vehicle

.
By doing this
,
a large
amount of the kinetic energy is
recovered
and
may be stored as electric energy in the
high-volt-
age battery
.
The conventional
brakes
are also ac-
tivated when the brakes
are pressed
very hard.
The strength of recuperation can depend on the
following
factors:
-
If you are in tiptronic mode

If the sport driving mode 5 was selected.
