BYD Dolphin Surf: real-world range in Ireland
The BYD Dolphin Surf is rated at 220 to 322 km on the WLTP lab cycle, but in real Irish driving you should plan for about 183 to 267 km. ShamAuto trims every WLTP figure by 17 per cent (the WLTP-minus-17% method) to give an honest real-world estimate for our roads, speeds and weather.
Because the Dolphin Surf was sold in 3 versions, the honest answer depends on which one you are looking at. The table below gives the real-world range for every variant.

| Version | Battery (kWh) | WLTP (km) | Real-world (km) | Charging |
|---|---|---|---|---|
| Comfort 43.2 kWh | 43.2 | 310 | 257 | CCS / 85 kW |
| Boost 43.2 kWh | 43.2 | 322 | 267 | CCS / 85 kW |
| Active 30 kWh | 30 | 220 | 183 | CCS / 65 kW |
How we calculate real-world range
WLTP is a standardised lab test, and almost no one matches it in normal driving. Rather than guess, we apply a single cautious adjustment to every car: real-world range = WLTP minus 17 per cent. It is deliberately conservative, so the figure is one you can plan a journey around. For the full method, read real-world range vs WLTP, explained.
Estimate the range for your conditions
Pick a version, the season and the kind of driving you do, then set the battery health to match your car. You always get an honest from-to corridor, not a single number - real range is a spread. Nothing is sent anywhere; the maths runs in your browser.
Lower this to your car's state-of-health to see its corridor.
About 245 to 270 km (mild weather, mixed driving)
The full honest spread at 100% battery health:
| City | Mixed | Motorway | |
|---|---|---|---|
| Mild | 255 to 285 | 245 to 270 | 215 to 250 |
| Cold | 185 to 225 | 190 to 230 | 190 to 230 |
Estimate based on WLTP minus 17% (our real-world baseline), adjusted for Irish conditions - not a guarantee. Real range also depends on speed, terrain, heating, tyres and driving style.
Winter range in Ireland
Cold weather temporarily cuts EV range, so in an Irish winter you may see less than the real-world figure above until things warm up. It is temporary, not battery wear. See EV winter range in Ireland for what to expect and how to win most of it back.
Frequently asked questions
What is the real-world range of a BYD Dolphin Surf?
In Irish driving, expect about 183 to 267 km from a BYD Dolphin Surf. That is the WLTP figure cut by 17 per cent (the WLTP-minus-17% method), which gives a more honest estimate than the lab number once you account for motorway speeds, terrain and weather. See the per-version table for each variant.
How much range does a BYD Dolphin Surf lose in winter in Ireland?
Irish winters are relatively mild, so expect a moderate drop rather than a drastic one - mostly from cabin heating, and more noticeable on short stop-start trips than on a steady run. Use the range slider above to see an honest from-to estimate for your conditions and battery health.
Do electric cars go further in the city or on the motorway?
Unlike petrol or diesel, an EV is usually more efficient in town - regenerative braking recovers energy in stop-start traffic, while steady high motorway speeds use more. The slider above shows the difference for this model.
Is the range slider a guarantee?
No - it is a conservative estimate built on our WLTP-minus-17% baseline and adjusted for Irish seasons and your battery health. Real range still depends on speed, terrain, heating, tyres and how you drive.
