2014 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 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:
POWER
The combustion engine provides the perform‐
ance to move the vehicle. If necessary, theSeite 31BMW eDRIVEAt a glance31

high-voltage battery is charged at the same
time.
The hybrid system always starts the combus‐
tion engine automatically.
Energy recovery: CHARGE The high-voltage battery is charged while driv‐
ing through energy recovery.
The electric motor acts as a generator and
converts the kinetic energy of the vehicle into
electric current.
Charging can take place in various situations
while the vehicle is in motion:▷When the vehicle is rolling if the accelera‐
tor pedal is not pressed.▷During vehicle braking.
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.
The mark in the instrument cluster is located
within the CHARGE range.
Sensible driving and early speed reduction are
important to make full use of the energy recov‐
ery feature.
Display The eDRIVE displays, refer to page 72, pro‐
vide information about the current state of the
drive and visualize the system's use in a dia‐
gram.
Energy-saving driving To save energy while driving, read the follow‐
ing information:
Before driving eDRIVE allows using the air conditioner even
before driving off. The stationary climate con‐
trol, refer to page 123, provides more range
than full air conditioning while driving.
Parked car ventilation during the charging
process can provide maximum range when
driving off.
During driving▷General driving tips, refer to page 140, for
increasing the range.▷Use the eDRIVE system efficiently, refer to
page 134, for an optimized driving style.▷ECO PRO mode, refer to page 141, for in‐
creasing the range.▷Display of hybrid system utilization, refer to
