Market or version specificIs the BYD Seal U DM-i worth considering?
Our view. One of the strongest equipment-for-money PHEVs to understand. It works best when charged routinely; range, battery size, and even its name vary by market.
How far can it go?
The published reference is 70–125 km electric (WLTP, version dependent). Compare it only with figures from the same test cycle. For a plug-in hybrid this is the electric-only range before the engine takes over.

- Toyota Prius Up to 86 km electric
- Toyota RAV4 Hybrid Not published Market dependent
- Honda CR-V Hybrid Not published Market dependent
Speed, temperature, wind, elevation, tyres, load and cabin heating or cooling all change real-world range. How EPA, WLTP and CLTC differ.
How quickly does it charge?
The highest published DC figure is Up to 18 kW. 30–80% in about 35 minutes claimed. A peak rate is reached briefly; the average across a session is lower.
Home charging time depends on the energy added, the car’s AC limit, the charger and the supply. Estimate a session with this car’s battery.
