Overview
Vehicle features and options
This chapter describes all standard, country-spe‐
cific and optional features offered with the series.
It also describes features that are not necessarily
available in your vehicle, for instance, due to the
selected options or country versions. This also
applies to safety-related functions and systems.
When using these functions and systems, the
applicable laws and regulations must be ob‐
served.

Special features of the BMW i
Combustion engine

High-voltage system
This BMW i is a hybrid vehicle. In addition to the
combustion engine, the vehicle features a high-
voltage system that consists of an electric motor
and a high-voltage battery among other things.
Concept
The hybrid system makes it possible to optimize
fuel consumption and driving characteristics.
An electric motor assists the combustion engine.
In certain driving situations, the vehicle can also
be driven using only electric power, thereby re‐
ducing fuel consumption.
Carbon body
The vehicle consists of the functional units:
▷ Drive module of aluminum.
In addition to this, the electric motor acts like a
generator: during braking and coasting, the elec‐
tric motor converts the vehicle's kinetic energy
into electricity. The current is stored in the high-
voltage battery and is used to drive the electric
motor.
▷ Life module of carbon fiber reinforced plastic,
CFRP.
Functions
Assistance from the electric motor:
ASSIST and eBOOST
Driving off and accelerating require a lot of en‐
ergy. To reduce fuel consumption during high
acceleration and to optimize acceleration, the

electric motor supports the combustion engine.
For this purpose, the electric motor is supplied
by the high-voltage battery.
When exerting gentle pressure on the brakes,
the vehicle is only braked by the electric motor.
When the brake pedal is depressed further, the
brake system is activated additionally. This is
why only part of the brake energy is used to
charge the high-voltage battery when exerting
firm pressure on the brake.
Electric driving: ePOWER
Under certain conditions, refer to page 96, the
vehicle is powered only by the electric motor.
The mark in the instrument cluster is located
within the CHARGE range.
Variable drive configuration
Sensible driving and early speed reduction are
important to make full use of the energy recovery
feature.
The electric motor drives the front axle and the
combustion engine the rear axle. Depending on
the operating condition, the vehicle has the op‐
tions of front-wheel drive, rear-wheel drive or
combined for four-wheel drive.
Display
Follow the instructions for electric driving
eDRIVE, refer to page 96, driving with the com‐
bustion engine DRIVE, refer to page 98, and
driving stability, refer to page 148.
The displays of the hybrid system, refer to
page 112, provide information about the current
state of the drive and show the system activity in
a chart.
Acoustic pedestrian protection
Energy-saving driving
Depending on the country-specific version, the
system generates a continuous driving noise
during electric driving at low speeds.
To store energy while driving, read the following
descriptions:
Before driving
Driving with the combustion engine:
POWER
The combustion engine provides the drive power
to move the vehicle. If required, the high-voltage
battery is charged at the same time.
eDRIVE allows use of the air conditioner even
before driving off. The stationary climate control,
refer to page 169, provides more range than us‐
ing full air conditioning while driving.
Parked vehicle ventilation during the charging
process can provide maximum range when driv‐
ing off.
The hybrid system always starts the combustion
engine automatically.
Energy recovery: CHARGE
During driving
The high-voltage battery is charged while driving
through energy recovery.
▷ General driving tips, refer to page 189, for in‐
creasing the range.
The electric motor acts as a generator and con‐
verts the kinetic energy of the vehicle into electri‐
cal energy.
▷ Use the eDRIVE system efficiently, refer to
page 182, for an optimized driving style.
▷ ECO PRO driving mode, refer to page 190,
for increasing the range.
Charging can take place in various situations
while the vehicle is in motion:
▷ Display of hybrid system utilization, refer to
page 113.
▷ When the vehicle is rolling if the accelerator
pedal is not pressed.
▷ Information on saving fuel, refer to page 189,
for reducing fuel consumption.
▷ During vehicle braking.
