specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.

The concept The hybrid system makes it possible to opti‐
mize fuel consumption and driving characteris‐
tics.
An electric motor assists the combustion en‐
gine. In certain driving situations, the vehicle
can also be driven using only electric power,
thereby reducing fuel consumption.
In addition to this, the electric motor acts like
an alternator: during braking and coasting, it
converts the vehicle's kinetic energy into elec‐ tricity. The current is stored in the high-voltage
battery and is used to drive the electric motor.
Functions
Electric driving: eDRIVE Under certain conditions, refer to page 74,
the vehicle is powered only by the electric mo‐
tor.
Acceleration boost: ASSIST and
eBOOST
Driving off and accelerating require a lot of en‐
ergy.
To optimize acceleration and to reduce fuel
consumption, the electric motor boosts the
combustion engine. To do this, the electric
motor uses the energy saved in the high-volt‐
age battery.
The ASSIST acceleration boost is automati‐
cally controlled and is not indicated in the in‐
strument cluster.
CoastingThe engine is automatically switched off. This
driving condition is referred to as coasting, re‐
fer to page 74.
Driving with combustion engine:
DRIVE
The combustion engine, refer to page 75,
provides the primary performance to move the
vehicle. If necessary, the high-voltage battery
is charged at the same time.
The hybrid system always starts the combus‐
tion engine automatically.Seite 31BMW ActiveHybridAt a glance31
