Manufacturer range figures for electric cars are almost always higher than what you'll see in real life — sometimes significantly so. Here's an honest guide to what those numbers actually mean, what affects your real-world range, and whether range anxiety is something you genuinely need to worry about.
Why are manufacturer range figures misleading?
EV range figures are tested under the WLTP standard — a controlled laboratory cycle that uses moderate speeds, mild temperatures and no accessories like heating or air conditioning. Real-world driving involves all of these, which is why you'll typically see 10–25% less range than the official figure in everyday use.
| Popular EV | Official WLTP range | Realistic real-world range |
|---|---|---|
| Tesla Model 3 (RWD) | 374 miles | 280–320 miles |
| Volkswagen ID.4 | 323 miles | 240–280 miles |
| Kia EV6 (Standard) | 328 miles | 250–290 miles |
| Nissan Leaf (40kWh) | 168 miles | 120–145 miles |
| MG4 Standard Range | 218 miles | 160–190 miles |
| Hyundai Ioniq 6 | 338 miles | 260–300 miles |
What actually affects your range?
Speed — the biggest factor
Air resistance increases dramatically with speed — at motorway speeds an EV uses significantly more energy per mile than at lower urban speeds. Driving at 70mph typically uses around 30–40% more energy per mile than driving at 50mph. If you're doing a lot of motorway driving, expect range closer to the lower end of estimates.
Temperature — especially cold weather
Cold weather affects EV range in two ways: the battery chemistry is less efficient at low temperatures, and you're using energy to heat the cabin. In winter, you might see 15–30% less range than in summer. Most modern EVs have heat pump systems that reduce this impact, but it's still noticeable in a cold UK January.
Heating and air conditioning
Running the heater on a cold morning is one of the most energy-intensive things an EV does. Many EV owners pre-condition their car while it's still plugged in — heating the cabin using grid electricity rather than battery power — which preserves range for the journey.
Driving style
Smooth, anticipatory driving extends range significantly. Heavy acceleration and hard braking waste energy. Using regenerative braking — where the car recovers energy as you slow down — helps. In urban driving with lots of stops and starts, regenerative braking can add meaningful range back.
Load and accessories
Roof boxes, bikes on the back, extra passengers and cargo all add weight and drag. A roof box at motorway speeds can reduce range by 10–15%.
Is range anxiety a real problem?
For most drivers — honestly, no. Here's why.
The average UK driver covers around 20–25 miles per day. Even the shortest-range modern EVs can do 120+ miles on a full charge. If you charge at home overnight, you start every day with a full battery and the concept of running low simply doesn't arise for daily driving.
Where range anxiety is genuinely real is for drivers who:
- Regularly do long motorway journeys of 200+ miles without a charge stop
- Don't have home charging and rely on public chargers
- Drive in particularly cold climates that reduce battery performance significantly
For everyone else — anyone with a home charger doing typical UK commuting and occasional longer trips — range anxiety fades quickly. Most EV owners report it as a non-issue within a month of ownership.

Range anxiety stops being a thing.
What about long motorway journeys?
This is where planning matters. A 300-mile motorway trip in a petrol car is straightforward. In an EV, you'd plan a charge stop — typically 20–30 minutes at a rapid charger to add 100+ miles. Apps like Zap-Map and A Better Route Planner show you working chargers on your route and plan stops automatically.
It requires more thought than petrol — but most EV drivers adapt quickly and find the charging stop often coincides naturally with a comfort break anyway. The frustration comes when chargers are broken or busy, which is improving but still an occasional reality.
How much range do you actually need?
A useful rule of thumb: you need enough range to cover your longest regular journey with 20% remaining as a buffer. For most UK drivers that means anything over 150 real-world miles is more than sufficient.
- Urban and suburban commuters — under 50 miles daily: almost any modern EV is fine
- Mixed use, occasional longer trips — 150–200 real-world miles: covers most needs comfortably
- Frequent long-distance drivers — 250+ real-world miles: worth paying for a higher-spec battery
Real-world range is 15–25% less than advertised — but it's usually enough
Expect 15–25% less than the official WLTP figure in real-world driving, with more reduction in cold weather and at motorway speeds. For most drivers doing typical UK mileage with home charging, this still leaves plenty of range for daily use. Range anxiety is a genuine concern for frequent long-distance drivers and those without home charging — for everyone else, it tends to disappear within weeks of ownership.
