Energy distribution in hybrid mode using map data*

Updated 2020-03-19

The Hybrid drive mode is the vehicle's default drive mode in which the electric motor and the combustion engine work separately or together in hybrid mode. If a destination has been selected in the navigation system*, the Predictive Efficiency1 function can use map data to effectively distribute the electric power consumption throughout the trip.

This can lower fuel consumption in comparison with normal hybrid mode, in which the vehicle first runs on electricity and then switches to the gasoline engine when the hybrid battery is discharged.

Function

If the distance to the selected destination is greater than the calculated range on the electric motor, the function will distribute the electric power to optimize consumption throughout the trip. This makes it possible to avoid situations in which normal hybrid mode would otherwise use a large portion of the electric power to e.g. use the electric motor at high speeds on a highway and then use the combustion engine at lower speeds during city driving.

The greatest fuel savings are achieved when

the trip begins on a highway
the trip is between 50 and 100 km (30 and 60 miles) long
the hybrid battery is fully charged at the start of the trip.

Requirements for the function

Certain conditions must be met for the function to be possible:

A destination must be set in the navigation system and the distance to the destination must be longer than the possible range using only the electric motor.
Hybrid drive mode must be selected.
The Hold and Charge functions must be disabled.
The hybrid battery must be charged.

Usage tips

If you commute and it is not possible to charge the vehicle at work, enter your workplace as a waypoint and your home as the destination. Discharging of the hybrid battery will then be distributed over the entire commute to and from work.

Add similar commutes, i.e. the route between two charges, as Favorites in the navigation system to facilitate access.
