BMW 3: Design
The main components of the electrical machine are:
- Rotor and stator
- Connections
- Rotor position sensor
- Cooling
The hybrid system in the G20 PHEV is a so-called parallel hybrid system. Both the combustion engine and the electrical machine are mechanically coupled with the sprockets. For vehicle drive it is possible to use both drive systems individually and at the same time.

Speed warning
Concept
A speed limit can be set that when reached will
cause a warning to be issued.
General information
The warning is repeated if the vehicle speed exceeds
the set speed limit again, after it has dropped
below it by 3 mph/5 km/h.
Adjusting
Via iDrive:
1. "CAR".
2. "Settings".
3. "General settin
Removing the flat high-voltage connector
Bridge for high-voltage interlock loop
Before the high-voltage connector can be
disconnected, the bridge for the high-voltage
interlock loop must first be removed. The bridge
closes the circuit of the high-voltage interlock
loop in a connected state. The SME and EME
control units continuous
