BMW i3: real-world range in Ireland
On paper the BMW i3 quotes 310 km WLTP. In practice, on Irish roads, that works out at around 257 km once you trim the lab figure by 17 per cent - the real-world range we show on every listing so you can compare cars honestly.
The i3 came in one version, so the figure above applies across the board - though your own range will still move with speed, load, terrain and the weather.

|---|---|---|---|---|
| 120Ah | 37.9 | 310 | 257 | CCS / 50 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.

The full honest spread at 100% battery health:
| City | Mixed | Motorway | |
|---|---|---|---|
| Mild | 245 to 275 | 235 to 260 | 210 to 240 |
| Cold | 175 to 220 | 185 to 220 | 185 to 225 |
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 BMW i3?
In Irish driving, expect about 257 km from a BMW i3. 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 BMW i3 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.
