What range will you really get?
WLTP is a lab figure measured in mild conditions. In a British winter - cold battery, heater on, motorway speeds - you'll see noticeably less. Enter a WLTP range to get a realistic estimate.
Your car UK
WLTP is the official UK lab figure, measured in mild conditions. It is the right starting point - just never the number you should plan a winter journey around.
Estimated real-world range UK
On a cold winter run expect roughly 180 miles from a 257-mile WLTP car - about 30% less than the headline. In mild weather, nearer 218 miles.
* Owner-reported rules of thumb (summer ~85%, winter ~70% of WLTP), not a physics model. Speed, terrain, tyres and heating all move the result. Bars share a 0-450 mi scale.
How this is worked out
These are rules of thumb from owner reports, not a physics model. We take the WLTP figure and apply two multipliers: about 85% in mild weather and about 70% in a cold winter. Your own mileage will vary with speed, terrain, tyres and how you drive - so treat the result as a sensible ballpark.
