The certified value for the vehicle's range should not be considered an expected driving range. The certified value is obtained during special test cycles and is primarily intended to be used for comparisons between different vehicles.
Range in the instrument panel
When the vehicle leaves the factory, or after a factory reset, range is based on the certified value.
Once the vehicle has been driven for a while, range is instead based on historical driving patterns. The amount of history used depends on the battery's charge level. The lower the charge level of the hybrid battery, the more quickly the range adapts to changed driving patterns.
Factors affecting driving range
There are a number of other factors in addition to historical trip data that affect range. The longest range is achieved under very favorable conditions when all factors positively influence range.
Factors affecting range include:
- speed
- climate control settings
- topography
- preconditioning
- tires and tire pressure
- the current traffic situation
- temperature and weather
- road conditions.
Range based on speed and ambient temperature
20 °C (68 °F) ambient temperature and passenger compartment climate control off.
0 °C (68 °F) ambient temperature and passenger compartment climate control on.
35 °C (95 °F) ambient temperature and passenger compartment climate control on.
-10 °C (14 °F) ambient temperature and passenger compartment climate control on.
The graph shows the approximate relationship between constant speed and driving range. Driving at a lower constant speed helps increase the electric motor's driving range.
Higher ambient temperature and deactivated climate system are also more favorable for range.
