EnglishDriving -> Driving with the combustion engine: POWER for your BMW i8 2014-2020
Driving
CONTROLS
As a result, other road users, for instance pedes‐
trians or cyclists, can better perceive the vehicle.
eBOOST
Accelerating quickly, such as when passing, re‐
quires the maximum available power from the
electric motor. To do this, depress the accelera‐
tor pedal firmly.
Driving with the combustion
engine: POWER
Energy recovery: CHARGE
Depending on the operating state, the combus‐
tion engine is automatically switched on:
▷ Selector lever position Sport is engaged.
▷ Speed for electric driving is exceeded.
Concept
The high-voltage battery is recharged in part
through energy recovery. The electric motor acts
as a generator when decelerating and converts
the kinetic energy into electrical energy.
▷ The high-voltage battery has an insufficient
charge.
▷ High-voltage battery is fully charged, for in‐
stance when driving downhill.
General information
Energy cannot be recovered in the following sit‐
uations:
▷ For improved traction, for instance on slip‐
pery roads.
▷ When accelerating heavily or on uphill grades.
▷ Selector lever position N is engaged.
▷ System-related demand from the hybrid
components.
▷ While driving stability control system DSC are
regulating, even if it is not indicated by an in‐
dicator light.
▷ Adapting to the course of the road when des‐
tination guidance is activated.
▷ The high-voltage battery is fully charged.
When reducing speed, the combustion engine is
switched off when the conditions for electric driv‐
ing, refer to page 96, are met.
▷ When temperature of the high-voltage bat‐
tery is very low or very high.
With cold external temperatures, it is possible
that the energy recovery is temporarily un‐
available after startup.
Assistance from the electric
motor
Functional requirements
Energy can be recovered if conditions such as
the following are met:
Concept
Depending on the operating state, the electric
motor provides assistance with additional propul‐
sive power.
▷ The vehicle is moving.
▷ Speed higher than approx. 12 mph/20 km/h.
▷ Selector lever in selector lever position D, R
or S.
ASSIST
▷ The high-voltage battery is not fully charged.
▷ Accelerator pedal is not operated.
During normal vehicle operation, the electric mo‐
tor assists the combustion engine, depending on
the situation.
