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.

 Reducing fuel consumption

General information The vehicle contains advanced technologies for the reduction of consumption and emission values. Fuel consumption depends on a number of different factors. Carrying out certain measures, such as a moderate driving style and regular maintenance, can influence fuel consumption an

 Procedure after an accident

The safety concept of the high-voltage system ensures that, even during or after an accident, there is no danger to the customer, the rescue services or the service employee. The high-voltage system is automatically switched off in the event of an accident in such a way that no dangerous voltage
