2015 BMW I8 fuel consumption

The driving style is efficient as long as the ac‐
celerator pedal pointer is within the lower
range highlighted in blue during acceleration
and deceleration.
The energy recovery occurs during coasting
and braking and is displayed in the perform‐
ance display by the accelerator pedal indicator.
The accelerator pedal pointer is within the
CHARGE range.
Efficient energy recovery:
▷The accelerator pedal moves to the left
within the blue range of the CHARGE dis‐
play, arrow 1.▷The energy use while driving can be opti‐
mized by efficient acceleration.
Efficient acceleration:
▷The accelerator pedal moves to the right
within the blue range of the eDRIVE dis‐
play, arrow 2.▷Use deceleration during coasting as often
as possible for energy recovery.
Brake according to traffic and circum‐
stances
Brake in accordance with the traffic conditions,
or there is the risk of accident.◀
Using drive modes and assistance
systems
Max eDRIVE
Max eDRIVE, refer to page 64, forces electric
driving. Electric driving is especially efficient
for short distances, low to medium speeds and
in stop-and-go traffic.
SAVE battery
SAVE Battery, refer to page 64, conserves the
electric range for a later point in time. In this
case, the vehicle is driven primarily by the
combustion engine.
ECO PRO ECO PRO, refer to page 145, supports a driv‐
ing style that saves on fuel consumption. For
this purpose, the engine control and comfort
features, e. g. the climate control output, are
adjusted.
Discharge of the high-voltage battery Longer idle periods, refer to page 190, can re‐
duce the charging state of the high-voltage
battery.
Do not allow the vehicle to sit idle for ex‐
tended periods with a low charging state
Before storing the vehicle for an extended pe‐
riod, check the battery charge indicator to en‐
sure that the high-voltage battery is fully
charged. During the idle period, connect the
vehicle to a charging station at a suitable
charging location. If necessary, the high-volt‐
age battery will be charged automatically.
Make sure that the charging process takes
place. Regularly check the charging state.
Don't allow battery charge status to drop too
low - it will damage the battery.◀

Increase rangeGeneral informationThe vehicle contains comprehensive technolo‐
gies for reducing the energy consumption and
for maximizing the range.
The range depends on a number of different
factors.
The implementation of certain measures, driv‐
ing style and regular maintenance can increase
range and thereby also reduce the environ‐
mental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Attached parts on the vehicle impair the aero‐
dynamics and increase the energy consump‐
tion.
Closing the windows
Open windows increase air resistance and
therefore lead to greater fuel consumption.
Tires General information Tires can affect energy consumption in various
ways, for instance energy consumption can be
influenced by tire size.Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflationpressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises energy consumption
and tire wear.
Standing air conditioning Run advance climate control, refer to
page 127, in the vehicle during charging if pos‐
sible before driving off.
Heating and cooling operations are very en‐
ergy intensive and substantially reduce the
electric range.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and proactively reduces fuel
consumption.
Longer braking procedures result in more effi‐
cient charging of the high-voltage battery via
energy recovery from braking.
Use coasting
When approaching a red light, take your foot
off the accelerator and let the vehicle coast to
a halt.Seite 144Driving tipsIncrease range144

Switch off any functions that
are not currently needed
Functions such as seat heating and the rear
window defroster require a lot of energy and
reduce the range, especially in city and stop-
and-go traffic.
Reel off these functions if they are not needed.
The ECO PRO driving program supports the
energy conserving use of comfort features.
These functions are automatically deactivated
partially or completely.
Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle efficiency and operating life.
The maintenance should be carried out by
your service center.
Also note the BMW Maintenance System, refer
to page 178.
ECO PRO
The concept
ECO PRO supports a driving style that saves
on fuel consumption. For this purpose, the en‐
gine control and comfort features, e. g. the cli‐
mate control output, are adjusted.
Under certain conditions the engine is auto‐
matically decoupled from the transmission in
the D selector lever position and the engine is
switched off. Selector lever position D remains
engaged.

Engine oilVehicle 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.
General information The engine oil consumption is dependent on
the driving style and driving conditions. When
a sporty driving style is used, the engine oil
consumption, e.g., is clearly higher.
Therefore, regularly check the engine oil level
after refueling.
When a dynamic driving style is used, such as
when cornering fast, the system is unable to
measure the engine oil level. With this driving
style, measure the engine oil level using a de‐
tailed measurement, refer to page 173.
The vehicle is equipped with electronic oil
measurement.
Electronic oil measurement Status display
The concept
The engine oil level is monitored electronically
while driving and shown on the Control Dis‐
play.
If the engine oil level reaches the minimum
level, a check control message is displayed.Requirements
A current measured value is available after ap‐
prox. 30 minutes of driving. During a shorter
trip, the status of the last, sufficiently long trip
is displayed.
With frequent short-distance trips, regularly
perform a detailed measurement.

Engine oil level display messages
Different messages appear on the display de‐
pending on the engine oil level. Pay attention
to these messages.
If the engine oil level is too low, within the next
125 miles/200 km Add engine oil, refer to
page 175.
Engine oil level too low
Add engine oil immediately; otherwise,
an insufficient amount of engine oil could re‐
sult in engine damage.◀
Take care not to add too much engine oil. Too much engine oil
Have the vehicle checked immediately;
otherwise, surplus engine oil can lead to en‐
gine damage.◀
Detailed measurement
