The WLTP driving cycle consists of several phases, which are based on everyday driving profiles of motorists from around the world.
While the current NEDC determines "urban, extra-urban and combined" values are based on of a theoretical driving profile, the WLTP uses "real" driving profiles drawn from a global statistical survey. The WLTP driving cycle is divided into four parts with different average speeds: low, medium, high and extra high. Each part contains a variety of driving phases, stops, acceleration and braking phases, etc. that represent everyday driving profiles. Each engine/transmission combination is tested with the most economical as well as the most fuel-intensive vehicle equipment.
Starting with the Astra, Opel will test each and every model. The published values define a range from the lowest to the highest consumption for each engine/transmission combination. This gives a good indication of the expected daily consumption of each model.
Please note: The values based on the WLTP driving cycle are determined using a standardized, predefined drive cycle on a test rig.
