WLTP to real-world — correction calculator

What range or consumption will you actually get?

Enter a WLTP manufacturer figure for range or consumption, choose the correction you find realistic, read the corrected indication.

Unit

Pick the unit of your manufacturer figure. The correction is a percentage, so the unit only labels the result. Petrol or diesel car: use l/100 km. Electric car: use km (range) or kWh/100 km. A CO₂ figure: use g/km.

The manufacturer figure per WLTP — range (km), consumption (l/100km or kWh/100km) or CO₂ (g/km). Unit does not matter: the correction is a percentage.

Not sure? Look up your model

Correction you find realistic

Electric car on the motorway or in winter? Many pick −20% or −25%. Mixed daily driving? −15%. Petrol or diesel? Usually −10% to −15%.

Guide figure only — your chosen percentage applied to the manufacturer figure. Driving style, route and temperature shift the actual value up or down.

How the correction works

The rule is simple: corrected value = WLTP value multiplied by (1 + your chosen percentage divided by 100). For a range, -20% means you count on four fifths of the WLTP figure. The percentages are fixed choices you make, not a prediction from us. For figures per model side by side, see the model pages with WLTP next to reported real-world data.

WLTP is measured on a standardised test cycle in mild conditions. Real driving rarely matches it: cold air and a cold battery cut EV range, motorway speeds raise both consumption and energy use, and a heavier right foot widens the gap. That is why a fixed lab figure tends to overstate what you reach day to day — and why you set your own margin above.

Typical WLTP figures and the correction band buyers commonly apply (indicative).
Vehicle type WLTP (typical) Common correction
EV range±400–600 km−15% to −25%
Petrol consumption±6–8 l/100 km−5% to −15%
Diesel consumption±5–7 l/100 km−5% to −10%

Bands are user-chosen guides, not a recommendation from us. Sources and method: how we rate and source.

No tax or financial advice. Every figure shows its source and reference date. Always compare with an independent adviser and the official source. Source: OEM WLTP datasheets; correction percentage chosen by the user. Reference date: calculation rule, not a time-bound figure.
