2014 BMW I8 engine

Gears will only be shifted at appropriate engine
and road speeds, for example downshifting is
not possible if the engine speed is too high.
The selected gear is briefly displayed in the in‐
strument cluster, followed by the current gear.
If the shift paddles on the steering wheel are
used to shift gears in automatic mode, the
transmission temporarily switches to manual
mode.
In the manual mode, if there has been no ac‐
celeration or shifting of the shift paddles within
a certain amount of time, the transmission
switches back to automatic mode.

Acceleration boost: eBOOST
Five bars indicate the available output of the
electric motor for the eBOOST 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 discharged, all five bars
are grayed-out.
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

Driving stability control systemsVehicle features and optionsThis 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.
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking.
The vehicle contains its steering power even
during full brake applications, thus increasing
active safety.
ABS is ready when car is ready to drive.
Brake assistant
When you apply the brakes rapidly, this system automatically produces the greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
DSC Dynamic StabilityControl
The concept DSC prevents traction loss in the powerwheels when driving off and accelerating.
DSC also recognizes unstable vehicle condi‐
tions such as fishtailing or nose-diving. Within
the physical limits DSC helps to keep the vehi‐cle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
A change in the drive type, refer to page 31,
can be made to improve traction.
Note Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, not
even with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Do not deactivate DSC when driving with
roof load
Do not deactivate Dynamic Stability Control
DSC when driving with roof load, e.g. roof-
mounted luggage rack.
Otherwise, driving safety is not given in driv‐
ing-critical situation due to the elevated center
of gravity.◀

TRACTION is displayed in the instrument clus‐
ter and the indicator lamp for DSC OFF lights
up.
Deactivating DTC Press button again.
TRACTION and the DSC OFF indica‐
tor lamp go out.
Performance Control Performance Control enhances the agility of
the vehicle.
To increase maneuverability, with a corre‐
spondingly sporty driving style, wheels are
braked individually. The resulting braking
power is simultaneously largely compensated
by an engine intervention.
Due to the variable drive configuration, this in‐
tervention can be done either on the front axle,
the rear axle or on both axles simultaneously.
Driving Dynamics Control The conceptThe Driving Dynamics Control helps to fine-
tune the vehicle's settings and features. Vari‐
ous programs can be selected for this purpose.
Note
Pressing the Driving Dynamics Control deacti‐
vates the Sport program, refer to page 69, of
the vehicle. The selector lever automatically
switches out of the Sport program in selector
lever position D. Use the Driving Dynamics
Control to select the COMFORT or ECO PRO
programs.At a glance

Activating COMFORT Press button repeatedly until COM‐
FORT is displayed in the instrument
cluster.
ECO PRO ECO PRO, refer to page 141, provides consis‐
tent tuning to maximize range.
Comfort functions and the engine controller
are adjusted.
The program can be configured to individual
specifications.
