FOR OVER THREE QUARTERS OF A
CENTURY, THE BASIC IDEA BEHIND THE
CAR WAS LEFT UNTOUCHED.
Until now. BMW i has launched a groundbreaking sports car with a
wide range of technological innovations – the BMW i8. The innovative
BMW eDrive technology effectively combines an electric motor with
a BMW TwinPower Turbo engine (hybrid electric vehicle). The result
is a breathtaking plug-in hybrid sports car with the fuel consumption
and emissions of a compact vehicle.
The weight of the BMW i8 is a result of the Life module – the passen-
ger cell made of light and extremely robust carbon fiber. It substantially
reduces the weight of the vehicle and has a significant impact on the
design of the BMW i8. The principle of intelligent lightweight design has
also been applied to all other components of the BMW i8. Moreover,
streamflow aerodynamics reduce drag and energy consumption.
With its dynamic proportions and sporty, progressive design, the BMW i8
embodies lightness – as well as efficiency and sheer driving pleasure.
The development process itself is the first of many innovations. In order
to ensure that the BMW i8 is a truly sustainable product, measurable
targets were defined at the design phase and throughout the entire life
cycle of the vehicle, from the extraction of raw materials, production
and use to recycling and the end of product life. The deliberate use of
recycled and environmentally friendly materials in production guarantees
holistic sustainability throughout the entire value chain.

A SUSTAINABLE COMBINATION:
INTELLIGENT ENERGY MANAGEMENT
FOR INSPIRING PERFORMANCE AND
OPTIMUM EFFICIENCY.
BMW has been pursuing its EfficientDynamics strategy for more than
a decade. However, no other vehicle combines driving pleasure and
sustainability like the BMW i8. Equipped with innovative BMW eDrive
technology that intelligently combines an internal combustion engine
with an electric drive system, the BMW i8 offers maximum perfor-
mance and sustainable efficiency.

In an urban environment, the BMW i8 offers a range of up to 37 kilo-
meters when traveling on electric power only. For longer distances,
support is provided by the BMW TwinPower Turbo engine – with an
especially intense boost feature in SPORT mode or maximum efficiency
in ECO PRO mode. A predictive power management system developed
specifically for the BMW i8 ensures optimal settings for the two drive
units at all times.

Additionally, every driver can also help to optimize sustainability when
recharging the car: if renewable energy is used to charge the battery,
CO² emissions are reduced even further. Therefore, BMW i recom-
mends green electricity suppliers to make an even greater contributi-
on to environmental protection.

text of that section should be
disregarded and the following text
should be read in lieu thereof:
The manufacturer of your vehicle
strongly suggests that you use
wheels and tires that have been
recommended by the vehicle
manufacturer for your vehicle type;
otherwise, for example, despite
having the same official size ratings,
variations can lead to body contact
and with it, the risk of severe
accidents.
The manufacturer of your vehicle
does not evaluate non-
recommended wheels and tires to
determine if they are suitable for
use on your vehicle.
15.At page 164, under the heading:

“Suitable.” Where it reads: “You
can add oils with the following
specifications,” that text should be
disregarded, and the following text
read in lieu thereof: “Add engine
oils that meet the following oil rating
standards: . . .”
18.At page 168, under the heading:
“Alternative oil types,” the text
preceding the chart should be

Parts and accessories
BMW recommends using parts and accesso‐
ries approved by BMW for this purpose.
Your BMW center is the right contact for genu‐
ine BMW parts and accessories, other prod‐
ucts approved by BMW and related qualified
advice.
BMW has tested these products for safety and
suitability in relation to BMW vehicles.
BMW can assume responsibility for them.
However, we cannot assume any responsibility
whatsoever for parts and accessories that have
not been specifically approved by BMW.
BMW cannot evaluate whether each individual
product from another manufacturer can be
used with BMW vehicles without presenting a
safety hazard. This guarantee is also not appli‐
cable when country-specific government ap‐
proval has been granted. Testing of this kind
may fail to embrace the entire range of poten‐
tial operating conditions to which components
might be exposed on BMW vehicles. Such
products could conceivably fail to comply with
BMW's own stringent quality standards.

BMW eDRIVEVehicle features and options
This chapter describes all standard, country-
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
Acceleration boost: 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 en‐
gine. For this purpose, the electric motor is
supplied by the high-voltage battery.
Electric driving: ePOWER
Under certain conditions, refer to page 61,
the vehicle is powered only by the electric mo‐
tor.
Variable drive configuration
The electric motor drives the front axle and the
combustion engine the rear axle. Depending
on the operating condition, the vehicle has the
options of front-wheel drive, rear-wheel drive
or bundled for four-wheel drive.
Follow instructions for electric driving eDRIVE,
refer to page 61, driving with the combustion
engine DRIVE, refer to page 62, and driving
stability, refer to page 105.
Acoustic pedestrian protection Depending on the country variant, the system
generates an artificial engine sound during
electric driving up to approx. 20 mph/30 km/h.
Driving with the combustion engine:

The combustion engine provides the perform‐
ance to move the vehicle. If necessary, theSeite 31BMW eDRIVEAt a glance31
