WLTP
What is WLTP?
The official EU laboratory test that has set the stated fuel consumption and electric range since 2018 — the figure you see on every brochure.
WLTP stands for Worldwide Harmonised Light Vehicles Test Procedure. Since September 2018 this has been the mandatory EU type-approval test for consumption, CO2 emissions and, on electric cars, range. The test runs on a chassis dynamometer with a fixed speed profile: four phases up to 131 km/h, together over 23 km and about 30 minutes.
A WLTP figure is a manufacturer statement under laboratory conditions, not a measurement we make ourselves. The test is closer to real-world use than its predecessor NEDC, but it still deviates from it: temperature, speed, load, tyres and driving style weigh heavily. In practice owners typically report higher consumption and, on EVs, a shorter range, especially in cold weather.
On this site WLTP is the default we set the stated consumption and range against. The figure always carries a manufacturer-statement label; the real-world picture comes from the owner reviews. To turn a WLTP figure into an indicative real-world value you set yourself, use the correction calculator under Tools.
