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.

The system provides an early look at cross traffic
at blind driveways and intersections.
General information
Road users concealed by obstacles to the left
and right of the vehicle can only be detected relatively
late from the driver's seat. The cameras in
the front and rear capture the side
System limits
Temperature
The tire inflation pressure depends on the tire's
temperature.
Driving or exposure to the sun will increase the
tire's temperature, thus increasing the tire inflation
pressure.
The tire inflation pressure is reduced when the
tire temperature falls again.
These circumstances may cause
