Range
A number of factors can affect electric driving range. The ability to achieve a long driving range varies according to the outside conditions and to how the vehicle is driven.
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
The estimated range is shown in the instrument panel.
When the vehicle is delivered from the factory, the range is based on the certified value. Once the vehicle has been driven for a while, range is instead based on historical 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.
20 °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 ratio between constant speed and range.
The graph shows that a lower speed gives a longer range. The ambient temperature also affects the range, so that very cold or very warm ambient temperatures give a shorter range.
Lines 1 and 2 show the approximate difference in range that is affected by the climate functions. Turning off the climate system is more favorable for the range.
