BYD Seal: real-world range vs WLTP
The BYD Seal has an official WLTP range of 323 mi–354 mi from a 82.5 kWh usable battery. Lab figures rarely match the road, so here is what to really expect — and a calculator to tune it to your weather, route and battery health.

Estimates for an as-new battery, based on the BYD Seal (2025). Cold weather and motorway speeds cut range the most; town driving recovers some through regenerative braking.

How to read these numbers
Each estimate takes the BYD Seal WLTP range and applies a transparent derate for temperature, driving profile, climate use and battery health. They are guides, not guarantees — your own efficiency, tyres, load and route all matter, so use the calculator above to match your situation.
Frequently asked questions
- What is the real range of the BYD Seal in winter?
- In cold weather (around −10 °C) with the heating on, expect roughly 235 mi from the BYD Seal — well below its WLTP rating, because batteries lose capacity in the cold and cabin heating draws extra power.
- How far does the BYD Seal go on the motorway?
- At sustained motorway speeds the BYD Seal manages about 277 mi. High speed is the single biggest drain on an EV, so motorway range is noticeably shorter than the WLTP figure.
- Why is the BYD Seal real range lower than WLTP?
- WLTP is measured in a controlled lab cycle. Real driving adds cold or hot weather, higher speeds, climate control and an ageing battery — together they typically cut range by 20–40%, which is what these estimates reflect.
