2015 BMW I8 fuel

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 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‐

Lighting lights up steady blue
After drive readiness is switched on, light turns
blue. The vehicle is ready to drive. The READY
indicator lights up in the instrument cluster. In
addition, a signal sounds.
Lighting off
Drive readiness, operating readiness and
radio-ready state are turned off. The vehicle is
in the idle state. The charging cable may be
connected.
Activating drive readiness1.Close the driver's door.2.Depress the brake pedal.3.Press the Start/Stop button.
Drive readiness is active, electric driving, Silent
Start or Start of the combustion engine.
Electric drive readiness, Silent Start
The vehicle is ready for driving without starting
the combustion engine.
Silent Start is possible if the requirements for
Electric driving, refer to page 64, are met.
Display READY indicates drive readi‐
ness.
Starting the combustion engine Enclosed areas
Do not let the engine run in enclosed
areas, since breathing in exhaust fumes may
lead to loss of consciousness and death. The
exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Unattended vehicle
Do not leave the vehicle unattended with
engine running or drive readiness switched on;
otherwise, it may pose a risk.
Before leaving the vehicle, engage lever in po‐
sition P P, and set the parking brake; other‐
wise, the vehicle is not secured against rolling
away.◀
Repeated starting in quick succession
Avoid trying to start the vehicle repeat‐
edly and in quick succession. Otherwise, the
fuel is not burned or is inadequately burned,
posing a risk of overheating and damage to the
catalytic converter.◀
The combustion engine is started with Acti‐
vate drive, refer to page 63, readiness under
the following conditions:▷The temperature of the hybrid system is
too high.▷The charge level or temperature of the
high-voltage battery is too low.
Driving away
1.Activate drive readiness.2.Apply the brake and engage lever in posi‐
tion P D, SPORT or R.3.Release the parking brake.4.Drive away.
Deactivating drive readiness
After parking the vehicle, you may hear noises due to operation of the hybrid system, such as
for cooling of the high-voltage battery.
After stopping the vehicle:
1.Depress the brake pedal.2.Set the parking brake.3.Press the Start/Stop button.
The READY indicator goes out and a signal
sounds. In case of longer idle times, follow the
instructions in the Care chapter, refer to
page 190.

Before driving into a car wash
So that the vehicle can roll into a car wash ob‐
serve instructions for going into an automatic
car wash, refer to page 187.
Electric driving: ePOWER
Note Awareness of vehicle reduced when
driven in electric mode
When driving in electric mode, note that, due
to the lack of engine noise, pedestrians and
other traffic might pay less attention to the ve‐
hicle due to missing engine noises. Please
take special care when parking or leaving a
parking space.◀
General information
In ePOWER, the vehicle is driven exclusively
electrically. ePOWER works automatically.
Depending on the charging state of the high-
voltage battery, maximum speed and range
achieved can vary.
For electrical driving, certain Conditions, refer
to page 64, must be satisfied.
Displays of the hybrid system, refer to
page 77.
Requirements▷State of charge and temperature of the
high-voltage battery is sufficient.▷Selector lever position D or R engaged.▷The accelerator pedal is only slightly de‐
pressed.▷The possible maximum speed for electric
driving is not exceeded.▷The driver's door is closed.Auto eDRIVE
General information
With each starting operation, Auto eDRIVE is
activated using the Start/Stop button.
In Auto eDRIVE, the vehicle is driven in hybrid
mode corresponding to the various driving sit‐
uations, i.e. the drive combines combustion
engine and electric motor. The respectively
most effective drive type is preferred.
SAVE Battery, maintaining charging
state
Should it be necessary, e.g., to conserve the
electrical range for a later point in time on the
trip, the current charging state of the high-volt‐
age battery can be maintained with this func‐ tion.
The function is possible under the following
conditions:▷The fuel fill level is sufficient.▷Engaged selector lever position D▷Drive mode Auto eDrive

ing.
With Max eDRIVE, a speed of
approx. 75 mph, approx.
120 km/h is possible.
In special situations, the speed limit can con‐
sciously be exceeded by applying the acceler‐
ator pedal beyond the full throttle point, kick‐
