How it is calculated
- Adjusted planning range = reference range × (1 − selected reduction percentage).
06 · Cold weather
Estimate a winter range adjustment
Apply a chosen cold-weather reduction to a known reference range. The tool helps you compare planning scenarios without claiming to predict the range of a particular vehicle at a specific temperature.

The percentage is a planning assumption, not a prediction for a specific temperature, vehicle, or trip.
How to use this tool
- Enter a reference range in kilometres and keep its test cycle in mind.
- Choose the 15%, 25% or 35% planning allowance.
- Calculate and compare the adjusted figure with your route length and an additional reserve.
Worked example
A 25% winter planning reduction
- Reference range
- 450 km
- Cold-weather allowance
- Cold conditions · 25%
Expected result About 338 km planning range
450 × (1 − 0.25) = 337.5 km, displayed rounded to 338 km. A separate arrival reserve is not subtracted.

How to read this result
The result is an adjusted scenario range. Speed, cabin heating, wind and battery temperature can produce a different real result; confirm charging options for the actual route.
Assumptions
- The preset reductions are broad scenarios selected by the reader, not measured model-specific data.
What this estimate cannot tell you
- Cabin heat, speed, wind, tires, route, preconditioning, and battery temperature can move real-world range well outside this estimate.
