WLTP
European type-approval test that has set the stated consumption and range since 2018.
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.
