Fuel consumption can then be reduced compared with normal hybrid drive when the car is first driven on electricity, to then change over to being driven by the internal combustion engine when the hybrid battery has been discharged.
If the distance to the destination is greater than the calculated range in electric drive, the function distributes the electric energy to the option most advantageous for the whole driving distance. This makes it possible to avoid situations where normal hybrid drive would otherwise use a large proportion of the electric energy, for example, to run electric drive at high speed on a motorway and then use the internal combustion engine at low speed in urban driving.
Greatest fuel saving is when the driving distance starts with motorway driving, is between 50 and 100 km (30 and 60 miles) long and the hybrid battery is fully charged when starting.
Conditions for the function
For the function to work requires that a number of conditions are met:
- A destination is set in the navigation system and the driving distance to the destination is longer than the range possible only on electric drive.
- Hybrid drive mode is selected.
- The Hold and Charge functions are deactivated.
- The hybrid battery is charged.
Tips for use
If the car is used for commuting to work and it is not possible to charge the car at the place of work, specify the place of work as an intermediate destination and your home as the final destination. The discharging of the hybrid battery will then take place over your runs both to and from work.
Add similar commuting routes, i.e. the route between two charging points, as Favourites in the navigation system to facilitate arrival.
