Introduction
The Electrical Machine Electronics (EME) is primarily used as control
electronics for the electrical
machine. It is also responsible for converting the direct current voltage from
the high-voltage b

Launch Control
Concept
Launch Control enables optimum acceleration
on surfaces with good traction under dry surrounding
conditions.
General information
The use of Launch Control causes premature
component wear since this function represents a
very heavy load for the vehicle.
Do not use Launch Control during the b
STANDARD
With a sufficient state of charge of the high-voltage battery unit,
all-electric driving of the vehicle with
maximum power of the electric drive is possible for up to 41 miles (66 km). The
maximum speed in this
case is 87 mph (140 km/h).
In the STANDARD variant, all ECO PRO setting
