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.

General information
The navigation system can determine the precise
position of the vehicle with the aid of satellites,
and can reliably guide you to every entered
destination.
Navigation data is stored in the vehicle and can
be updated from a USB storage device.
