2015 BMW I8 fuel consumption

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.

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 respectively applicable country
provisions must be observed when using the
respective features and systems.
BMW eDRIVE Special features of the BMW i
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 elec‐
tric motor and a high-voltage battery among
other things.
Carbon bodyThe vehicle consists of two different functional
units: the drive module made from aluminum
and the life module made from carbon fiber re‐
inforced plastic (carbon).At a glance1Vehicle battery2Electrical drive unit3High-voltage battery4Fuel filler flap5Combustion engine6Charging port
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‐

Energy recovery: CHARGE
The energy recovered is indicated in the COM‐
FORT and ECO PRO modes by four bars in the
CHARGE range. The high-voltage battery is
being charged. Depending on the available
output of the high-voltage battery, more or
less eBOOST could be recovered. If the high-
voltage battery is completely charged, no en‐
ergy can be recovered. The four bars are
grayed-out.
For further information, please refer to Energy
recovery CHARGE, refer to page 66.
Acceleration boost: eBOOST
Five bars indicate the available output of the
electric motor for the eBOOST, refer to
page 31, acceleration boost. Depending on the
available output of the high-voltage battery,
there could be more or less eBOOST available.
If the high-voltage battery is completely dis‐
charged, all five bars are grayed-out.
Maintaining charging state
In the Maintaining charging state mode, the
arrow indicates the charging state of the high-
voltage battery that should be conserved for a
later point in the trip.
▷Gray arrow: maintaining charging state
mode deactivated.▷Orange arrow: maintaining charging state
mode activated.
Activating/deactivating the Maintaining charg‐
ing state mode, refer to page 64.
