The driver can influence some factors, but has no influence over others.
The longest range is achieved under extremely favourable conditions when all factors have a positive impact.
Factors that affect the range
Factors the driver cannot influence
There are several external factors that affect the range in varying degrees:
- traffic situation
 - short driving distances
 - topography
 - outside temperature and headwind
 - road condition and surface.
 
The table shows the approximate ratio between the outside temperature and the range of a car with reduced climate settings. A warmer outside temperature has a positive effect on range.
| 25°C | 105 % | 
| 20°C | 100 % | 
| 10°C | 90 % | 
| 5°C | 85 % | 
| 0°C | 80 % | 
| 5°C | 75 % | 
| 10°C | 70 % | 
Factors the driver can influence
The driver should be aware that the following factors affect the range so he/she can operate the car in an energy-efficient manner:
- regular charging
 - Preconditioning
 - drive mode Pure
 - Climate settings
 - speed and acceleration
 - drive mode Save
 - tyres and tyre pressure.
 
The table shows the approximate ratio between constant speed and range, where a lower constant speed has a positive effect on range.
| 100 km/h (62 mph) | 70 % | 
| 90 km/h (56 mph) | 80 % | 
| 80 km/h (50 mph) | 90 % | 
| 70 km/h (43 mph) | 100 % | 
| 60 km/h (37 mph) | 110 % | 
| 50 km/h (31 mph) | 120 % | 
Note
- The values shown in the tables relate to a new car.
 - These are not absolute values, but are dependent upon driving behaviour, environment and other circumstances.
 
Driving with electric operation
Select drive mode Pure for the most energy-efficient driving - to get as far as possible with electric power alone.
Select drive mode Save at higher speeds during drives which are longer than the range of the electricity.
